Pectin is a soluble fiber in the family of carbohydrates, a long chain built on galacturonic acid units that sits in the cell walls of fruits and vegetables. In water it swells into a gel, which is why jam sets, and that gel is what the research on cholesterol, blood sugar after a meal and stomach emptying is about. Our page on soluble fiber covers it together with beta-glucan and inulin.
Most commercial pectin comes from leftovers. Apple pomace and orange peel are the two major sources, and a review puts the pectin content of apple pomace at about 10 to 15% of dry matter and of citrus peel at 20 to 30%. The EU allows two health claims for pectins, one for blood cholesterol at 6 g a day and one for the blood glucose rise after a meal at 10 g per portion. Those are amounts of isolated pectin. A 2025 review puts the pectin in many fruits and vegetables at only 0.1 to 2.5% of their fresh weight.
What most readers do not know is that the type of pectin matters. In one crossover trial, 15 g a day of citrus or apple pectin with a degree of esterification of 70 lowered LDL cholesterol by 7 to 10%, and pectins with a lower degree of esterification, a lower molecular weight or no esterification did less. Pectin is also not absorbed intact. EFSA describes it as extensively fermented by gut bacteria.
Health benefits of pectin
Pectin’s best-supported effect is a modest fall in LDL cholesterol. A meta-analysis of 67 trials of soluble fibers, pectin among them, found 0.057 mmol/L less LDL cholesterol for each gram, and the EU accepts a cholesterol claim for pectins at 6 g a day. The size depends on the type: in a crossover trial, high-methoxyl pectin lowered LDL by 7 to 10% at 15 g a day. The EU also accepts a claim for a smaller blood glucose rise after a meal, though the human evidence we found is small meal tests. Pectin slows stomach emptying and raised fullness in short trials, and it has been tested against diarrhea in children, once on its own and once mixed with chamomile. The evidence for “modified citrus pectin” is small, uncontrolled or null, and one study was sponsored by its maker. Trials of apple products and of sugar beet pectin were mixed or null. Most trials use isolated pectin, not fruit, and each card says which. Here is what 21 studies found, strongest evidence first, including the trials that found nothing. Studies of particular forms of pectin are in the section on forms below.
In a meta-analysis of 67 controlled trials, each gram of soluble fiber (2 to 10 g a day) lowered LDL cholesterol by 0.057 mmol/L
The fibers were pectin, oat bran, guar gum and psyllium, and each gram also lowered total cholesterol by 0.045 mmol/L. Oat, psyllium and pectin worked by amounts that did not differ significantly, and triglycerides and HDL cholesterol did not change significantly. The authors call the effect small within the practical range: 3 g of soluble fiber from oats, about 3 servings of oatmeal, lowers total and LDL cholesterol by about 0.13 mmol/L. This is a result for soluble fibers together, not for pectin alone.
The EU allows the claim that pectins contribute to the maintenance of normal blood cholesterol levels, for foods that provide 6 g of pectins a day
The claim is in Regulation (EU) No 432/2012, based on EFSA’s 2010 opinion on pectins. A food can carry it only if it provides a daily intake of 6 g of pectins, and the consumer must be told that the effect comes with that daily intake. The label also has to warn of choking for people with swallowing difficulties or who take it without enough fluid, and advise taking it with plenty of water.
The EU also allows the claim that eating pectins with a meal contributes to the reduction of the blood glucose rise after that meal, at 10 g per portion
The claim may be used only for food that contains 10 g of pectins per quantified portion, and the consumer must be told that the effect comes from eating the 10 g as part of the meal. The same choking warning applies. Both pectin claims rest on the same EFSA opinion. They cover isolated pectin added to food, not a serving of fruit.
In adults with mildly high cholesterol, 15 g a day of citrus or apple pectin with a degree of esterification of 70 lowered LDL cholesterol by 7 to 10% against cellulose
Crossover trials in which people ate the pectin or cellulose with food for 4 weeks. Pectins with a lower degree of esterification (35 or 0), a lower molecular weight or an orange pulp source worked less well. At 6 g a day for 3 weeks, citrus pectin and a high molecular weight pectin, both with a degree of esterification of 70, lowered LDL by 6 to 7% without a change in total cholesterol. High-sensitivity C-reactive protein and homocysteine did not change. A trade report names Cargill, a pectin maker, as the funder.

In 18 trials of apples and apple products, total cholesterol fell by 2.69 mg/dL, a change that did not reach statistical significance
Systematic review and meta-analysis of randomized trials of whole apples, apple extracts and apple juice, so the result is not for pectin alone. LDL fell by 2.80 mg/dL, also not significant. Against a placebo control, both total and LDL cholesterol fell significantly, and people with higher starting cholesterol gained more. HDL fell by 1.04 mg/dL, and the other markers were mostly unchanged.
In 255 children with acute diarrhea, an apple pectin and chamomile extract preparation reduced stool frequency more than placebo
Multicenter, randomized, double-blind trial in children aged 6 months to 6 years, treated as outpatients. All of them received a glucose-electrolyte solution on the first day. The product combined apple pectin with chamomile extract, so the result cannot be credited to pectin alone. Side effects were similar to placebo.
In 62 infant boys with persistent diarrhea, a rice diet with pectin ended diarrhea by day 3 in 59%, against 15% on rice alone
Double-blind trial in hospital for 7 days, in boys aged 5 to 12 months. The rice-based diets had either 4 g/kg of pectin (19 boys), 250 g/L of cooked green banana (22) or nothing added (21). By day 4, 82% had recovered on pectin, 78% on green banana and 23% on rice alone. Pectin and banana also reduced stool amount, rehydration fluid and vomiting.
In 100 healthy adults, 15 g a day of sugar beet pectin for 4 weeks did not change gut bacteria, short-chain fatty acids or breath compounds
Randomized, double-blind, placebo-controlled trial in 52 young adults and 48 older adults, with maltodextrin as the placebo. Fecal bacteria were profiled by gene sequencing, fatty acids by gas chromatography and breath by mass spectrometry. At the start, young and older adults had similar profiles, with five bacterial genera differing in abundance.
In 66 adults with abnormal glucose metabolism, a sugar beet pectin drink for 12 weeks did not improve fasting or after-meal glucose or blood lipids
Randomized, double-blind, placebo-controlled trial with parallel groups. The drink, 4 dl a day, had sugar beet pectin (22 people), polydextrose (22) or no added fiber (22), and 24 people had a meal test. HbA1c rose marginally in both fiber groups and HDL cholesterol rose in both. The authors concluded that neither fiber had positive effects on glucose or lipids.
In 10 healthy young adults, 15 g a day of high- or low-methoxyl pectin lowered total cholesterol by 18% and 16%
Pectin was added to the usual diet. HDL cholesterol and triglycerides did not change, and stool fat and steroid excretion did not differ between the two pectins. The authors suggest that the gel-forming property of pectin, not a difference in bile acid binding between the two types, explains the fall. A small study in young, healthy people.
In 8 people, 10 g of pectin added to marmalade lowered blood glucose 15 minutes after a breakfast from 6.18 to 5.64 mmol/L
The test breakfast was bread, butter, marmalade and tea. Insulin was significantly lower at 15, 30 and 45 minutes. The same report tested guar gum in a liquid meal in 4 people, which lowered glucose more. These were single-meal tests, not long-term trials.
In 74 healthy adults, 5 g or more of pectin in orange juice raised fullness for up to 4 hours
US Army employees of normal weight (49 men and 25 women) drank orange juice with 5, 10, 15 or 20 g of pectin on one day and plain juice on another, then ate ice cream 4 hours later. Fullness was higher with pectin, and the dose made no significant difference (P=0.121). The effect lasted 60 minutes after the ice cream. The trial rated fullness; it did not measure food eaten or weight.
In 25 healthy adults, low-methoxyl pectin in orange juice raised fullness most, and amidated pectin had no effect
Orange juice with high-methoxyl, low-methoxyl or low-methoxyl amidated pectin, at a low or a high thickness, was drunk with a standard breakfast by 10 men and 15 women. High-methoxyl pectin had smaller but significant effects. Thickness measured in a simulated digestion did not track fullness closely, so thickness alone did not explain the results.
In 9 obese adults, 15 g of pectin slowed stomach emptying of a meal (half-time 116 against 71 minutes) and raised fullness
The same meal was eaten on two days in random order, with 15 g of pectin on one and 15 g of methylcellulose on the other. Fullness scores were 98 against 74. Release of the gut hormones cholecystokinin and pancreatic polypeptide did not change.
In 6 healthy men, 15 g of pectin delayed stomach emptying of liquid and solid meals
Pectin lengthened the emptying half-time and changed gut movement little. It lowered insulin 15, 30 and 45 minutes after the liquid meal but did not change blood glucose, and it had no effect on glucose, insulin or glucagon after the solid meal. The authors say the effect may come from thickening the meal. In their first tests, 15 g was the best dose.
In 6 people with an ileostomy, 70 to 100% of the uronic acids from 15 g of citrus pectin came out in the ileostomy output, so little was digested
The people took 15 g a day of citrus pectin for 3 days on a constant low-fiber diet. Apparent iron absorption fell significantly, while phosphorus, calcium, magnesium and zinc absorption did not change. Ileostomy output of fat, nitrogen, sodium and potassium rose. The authors found only limited digestion of pectin in the stomach and small intestine.
In 14 men, 20 g of pectin raised breath hydrogen, a sign of fermentation, in only 4
Each man also took 20 g of cellulose and 6 g of lactulose on separate occasions. Four men responded to both lactulose and pectin, 7 to lactulose alone and 3 to none. Hydrogen production depended on the person’s gut bacteria, and the men who produced it carried more Clostridium species.
In a proof-of-concept trial in people with high blood pressure and raised galectin-3, modified citrus pectin did not change markers of collagen turnover
Randomized, placebo-controlled trial of a modified citrus pectin meant to block galectin-3, a protein, and tested its effect on markers of collagen metabolism. The authors say the effect of blocking galectin-3 in people with heart failure deserves more study.
In healthy adults, 15 g a day of modified citrus pectin raised urinary arsenic by 130% and cadmium by 150%
Pilot trial with 5 days at 15 g and one day at 20 g, comparing urine with each person’s baseline. Lead excretion rose by 560%, but with a p-value below 0.08 that is not significant at the usual 0.05 cut-off. The study measured metals in urine, not body stores or health. The modified pectin had a degree of esterification of 3.8%.
In 59 men with prostate cancer that had returned after treatment, 75% had a longer PSA doubling time after 6 months of modified citrus pectin
Phase II study with no comparison group: 4.8 g three times a day for 6 months. Overall 78% responded, and no patient had grade 3 or 4 toxicity. PSA doubling time is a blood marker, not survival. One author developed the supplement company that sponsored the study. A 2023 report followed the patients without progression for 12 more months.
In a systematic review of lab fermentation studies, pectins were slowly but completely fermented, with more acetate than other fibers
In vitro studies with human stool bacteria. Pectin raised groups such as Ruminococcaceae, Bacteroides and Lachnospira, and the degree of esterification, the ratio of two pectin regions and the molecular weight were the most influential structural factors. The authors say the prebiotic effect still needs confirming in people. No people were involved.
How strong is the cholesterol evidence?
The EU claim rests on older evidence. FSANZ, the food regulator of Australia and New Zealand, noted in a 2015 review that EFSA based its opinion on one review and one meta-analysis, from 1987 and 1999, and that the 1999 meta-analysis included foods with mixed fibers or an undefined pectin content. FSANZ then ran its own systematic review and found only 7 randomized trials that tested pectin of known content, at 9 to 36 g a day. Of the 4 high-quality trials, 3 found a significant fall in total cholesterol and 1 a small, non-significant rise. FSANZ rated the certainty as moderate, and said there is very little reliable evidence that pectin lowers cholesterol in people whose cholesterol is already normal, below 5.5 mmol/L.
What is known about modified citrus pectin
Modified citrus pectin is pectin broken into shorter chains and sold as a supplement. Most of the research on it is in cells and animals, where it is described as blocking galectin-3, a carbohydrate-binding protein involved in cancer, in the words of the authors of the prostate study above. In people we found the small studies above: a urine test in healthy adults, a prostate cancer study with no comparison group whose authors include the developer of the sponsoring company, and one placebo-controlled trial that found no change in collagen markers. We found no randomized trial showing that it treats cancer, and no trial showing that it lowers the body’s load of toxic metals or improves health.

Foods high in pectin
We do not rank foods by pectin because our database holds no measured pectin values, so the figures below are published measurements, not our data. Pectin sits in the cell walls of fruits and vegetables such as apples, bananas, oranges, lemons, blueberries, grapefruit, carrots, fava beans and tomatoes. A review puts it at about 0.1 to 2.5% of the fresh weight of many fruits and vegetables, and estimates average intake from them at about 5 g a day on 500 g of produce, adding that real fruit and vegetable intake in most countries is under 200 g a day. See our pages on apples, oranges, lemons, bananas and carrots.
The richest sources are by-products. Citrus peel holds about 20 to 30% pectin and apple pomace, a food processing by-product, about 10 to 15%, both as a share of dry matter, and sugar beet and sunflower head residues about 10 to 20%. These are the industrial raw materials, not foods people eat. Our arithmetic shows why the claim doses are far from a normal diet: 6 g of pectin is the amount in 240 g of a food at the top of the 2.5% range, and in 6 kg of a food at the bottom, 0.1%. Ripeness, storage and processing change pectin, and heat degrades it, so a measured value is a rough guide.
| Food or source | Pectin | What the number is | Source |
|---|---|---|---|
| Many fruits and vegetables | 0.1 to 2.5 g per 100 g | Range quoted in a 2025 review, on a wet basis | 1 |
| Citrus peel | About 20 to 30 g per 100 g of dry matter | Pectin content, an industrial raw material | 2 |
| Apple pomace | About 10 to 15 g per 100 g of dry matter | Pectin content, a food processing by-product | 2 |
| Sunflower head residues, sugar beet | About 10 to 20 g per 100 g of dry weight | Pectin content, industrial raw materials | 2 |
| Apple pomace, extracted with subcritical water | Yield about 10 to 17% | Share of pectin extracted, which depends on the method | 2 |
| Apple pomace, citric acid extraction | Yield 22% | Highest of five methods compared in one study | 3 |
| Orange peel, acid extraction with microwave heating | Yield about 14 to 18% | Share of pectin extracted, from a table in a review | 2 |
| Orange peel, citric acid extraction | Yield 18.18% | Best result of an optimization, with a degree of esterification of 50% | 4 |
Jam is the food most people link with pectin, but we found no measurement of the pectin in a spoonful of jam to set against the 6 g or 10 g behind the EU claims. High-methoxyl pectin gels only at a pH below 3.5 and with more than 55% sugar, so jam is mostly sugar. See our page on sugars.

How pectin works
Most of what we know about how pectin works comes from meal tests, a few physiology trials and lab fermenters, and what it does to health over months is tested in the cards above. The main ideas are that its chemistry decides how it gels, that it thickens the stomach contents, that little of it is digested before the colon, and that its effect on cholesterol depends on its type and dose. Here is each one, and what has been seen in people.
Its chain and its esterification decide how it gels
Pectin has no single structure. It is a family of polysaccharides built on a backbone of galacturonic acid units, and the makeup depends on the plant, the ripeness and the processing. In the main region, homogalacturonan, some of the acid groups carry a methyl group, which is called esterification. Pectins with more than half of their groups esterified are called high-methoxyl, and those with 5 to 50% low-methoxyl. High-methoxyl pectin gels at a pH below 3.5 with more than 55% sugar, the conditions in jams and jellies. Low-methoxyl pectin gels with calcium ions, in an “egg-box” pattern.
Schematic of the two kinds of pectin. Each circle is a galacturonic acid unit, and the pattern of esterified units is illustrative. Not to scale.
It thickens the stomach contents and slows emptying
In 6 healthy men, 15 g of pectin delayed the emptying of liquid and solid meals, and the authors think the thickness of the meal explains it. In 1979 Holt and colleagues found that pectin lowered blood glucose after a glucose drink in 7 volunteers, and that adding guar gum and pectin slowed stomach emptying and paracetamol absorption. They concluded that the effects on glucose tolerance could be due simply to slower stomach emptying. A 1978 trial gave groups of 4 to 6 volunteers 12 g of fiber (or a fiber-like substance) equivalent with a 50 g glucose test. Guar, pectin, gum tragacanth, methylcellulose, wheat bran and cholestyramine each lowered blood glucose at one or more time points, and the fall in the peak correlated with viscosity (r = 0.926). Not every trial found a glucose effect: pectin did not lower blood sugar in the stomach-emptying study, and a sugar beet pectin drink did not change glucose over 12 weeks. The chart shows the stomach-emptying result in 9 obese adults.
Stomach emptying half-time and fullness after the same meal with pectin or methylcellulose, drawn to scale. A longer half-time means slower emptying. Both differences were significant (p below 0.001).
Little is digested, and gut bacteria ferment the rest
Human enzymes do little to pectin. In 6 people with an ileostomy, 70 to 100% of the uronic acids from 15 g of citrus pectin came out in the ileostomy output. EFSA’s 2017 opinion says pectin is not absorbed intact but extensively fermented by gut bacteria, and that the products formed in the gut are similar to manufactured pectin-derived acidic oligosaccharides. A systematic review of lab fermentations found that pectins are slowly but completely fermented, with more acetate than other fibers, and that this raised groups such as Ruminococcaceae and Lachnospira. These are results in a bottle. In people, 15 g a day of sugar beet pectin for 4 weeks did not change fecal bacteria or short-chain fatty acids, and breath hydrogen showed fermentation of 20 g of pectin in 4 of 14 men.
What happens to pectin in the gut. The ileostomy and breath findings come from small human studies and the fermentation pattern from lab models. Not to scale.
Type and dose set the cholesterol effect
The likely route is physical. FSANZ calls it plausible that soluble fiber lowers cholesterol by physically inhibiting the re-uptake of bile acids, and in the Judd trial both high- and low-methoxyl pectin lowered total cholesterol without a difference in stool steroids, which the authors take to mean the gel itself matters. The two best trials do not fully agree on the details. Judd found no difference between pectin types at 15 g a day in 10 people. Brouns found that a high degree of esterification and a high molecular weight were important, and that citrus and apple pectin with the same degree of esterification worked equally well. Dose matters too. The chart applies the pooled slope from the 1999 meta-analysis to three daily amounts, as our arithmetic.
Expected fall in LDL cholesterol at three daily amounts of soluble fiber, drawn to scale. Our arithmetic: 0.057 mmol/L per gram multiplied by 3, 6 and 10 g, inside the 2 to 10 g range of the meta-analysis. The slope covers pectin, oat bran, guar gum and psyllium together, individual trials vary, and the pectin type changes the result.
What has been seen in people
For cholesterol the pooled and regulatory evidence agrees on a modest effect, roughly 0.2 to 0.6 mmol/L of LDL for 3 to 10 g of soluble fiber by the straight-line arithmetic above, and 7 to 10% at 15 g of the right pectin in one trial. FSANZ’s own review was less sure, with moderate certainty. For blood glucose, the 1977 marmalade test and the 1978 viscosity test were small, and two later trials found no glucose effect. For fullness, single-meal tests in 74, 25 and 9 people found that pectin raised ratings, except for amidated pectin, but we found no trial that tested pectin for weight loss. For diarrhea, the trials are in children. For the gut, a human trial showed fermentation in some people, and another found no change in bacteria.

How much pectin do you need?
No daily need or upper limit is set for pectin on its own. The amounts behind the EU health claims are 6 g a day for blood cholesterol and 10 g in a meal for the blood glucose rise after it, and both are amounts of isolated pectin added to food. Pectin counts toward total fiber, where EFSA sets an adequate intake of 25 g a day for adults and the US values run from 21 to 38 g by age and sex, as shown on our fiber page.
| Source | Group | Value | Notes |

Forms of pectin: absorption and effects
Pectin reaches people inside whole fruit and vegetables, as an extracted powder or liquid used in jams, jellies and other foods (the food additive E 440), in medicines such as a kaolin-pectin antidiarrheal suspension, and as “modified” citrus pectin sold as a supplement. For pectin the useful question is not absorption, since it is not absorbed intact. What differs between forms is how thick the pectin gets and how readily it is fermented, which depend on its degree of esterification, its chain length and its source.
The honest bottom line is that the best human evidence for cholesterol is for isolated high-methoxyl pectin at several grams a day, and that the trials differ so much in type and dose that we cannot rank the forms. Two popular claims have little behind them. We found no trial in which pectin was tested for weight loss, only fullness ratings after single meals. And we found no randomized trial of modified citrus pectin for cancer, only small studies with no comparison group, and the study of metals measured urine, not health.
| Form | What it is | What studies show | Source |
|---|---|---|---|
| Pectin in whole fruit and vegetables | Part of the plant cell wall, eaten with other fibers, sugars and nutrients | In 18 trials of whole apples, apple extracts and apple juice, total cholesterol fell by 2.69 mg/dL, which was not statistically significant. The result is not for pectin alone. | 1 |
| High-methoxyl pectin (citrus, apple) | Extracted pectin with more than half of its acid groups esterified, the type used in jams | 15 g a day with a degree of esterification of 70 lowered LDL cholesterol by 7 to 10% against cellulose. 15 g of high-methoxyl pectin lowered total cholesterol by 18% in 10 young adults. | 2, 3 |
| Low-methoxyl pectin | Extracted pectin with 5 to 50% of its groups esterified, which gels with calcium | 15 g lowered total cholesterol by 16% in 10 young adults, and 15 g with a degree of esterification of 35 did less than 70 for LDL. In orange juice, low-methoxyl pectin raised fullness most. | 2, 3, 4 |
| Amidated pectin (E 440ii) | A variant of low-methoxyl pectin approved as an additive | Amidated pectin in orange juice had no effect on fullness in 25 adults. EFSA reached the same safety conclusion for it as for plain pectin. | 4, 5 |
| Sugar beet pectin | Pectin from beet pulp | 15 g a day for 4 weeks did not change gut bacteria or short-chain fatty acids in 100 adults. A 12-week drink did not improve glucose or lipids in 66 adults. | 6, 7 |
| Apple pectin with chamomile extract | A branded diarrhea preparation for children | Reduced stool frequency in 255 children with acute diarrhea. The pectin cannot be separated from the chamomile. | 8 |
| Modified citrus pectin | Citrus pectin broken into shorter chains. One study measured a weight-average molar mass of 15,400 and a degree of esterification of 3.8%. | Urinary arsenic and cadmium rose in 15 g a day pilot. In 59 men with prostate cancer, 75% had a longer PSA doubling time, with no comparison group. One placebo-controlled trial found no change in collagen markers. | 9, 10, 11 |
Two regulatory opinions cover pectin as a food additive, strongest evidence first, 2 in all.
EFSA found no safety concern for pectin (E 440i) and amidated pectin (E 440ii) as food additives and saw no need for a numerical limit
The panel noted that pectin is not absorbed intact but extensively fermented, and that rats showed no adverse effects at up to 5,000 mg/kg of body weight a day. In humans, 36 g a day (515 mg/kg a day) for 6 weeks caused no adverse effects. The highest estimated exposure from additive use was 442 mg/kg a day, in toddlers at the 95th percentile.
For babies under 16 weeks, EFSA found the margin of safety for pectin additives was below 1 in some scenarios, and advised lower maximum levels
The clinical studies provided had low internal validity, so a reference point came from a piglet study instead. At the maximum permitted levels, the methanol released from pectin could lead to adverse health effects in infants under 16 weeks old. The panel recommended lowering the maximum levels in two categories of infant food.

Is pectin safe? Supplements, dose and interactions
Pectin from food is not a safety concern for most people. EFSA found no safety concern for pectin as a food additive and no need for a numerical limit, and 36 g a day for 6 weeks in humans caused no adverse effects. The exceptions are very young infants, and a few practical points below.
- Gas and choking. Pectin is fermented in the colon, and breath hydrogen rose in 4 of 14 men after 20 g. The EU requires a warning of choking for people with swallowing difficulties, and advice to take pectin with plenty of water, on its claims.
- Minerals. In 6 people with an ileostomy, 15 g of citrus pectin lowered apparent iron absorption and left phosphorus, calcium, magnesium and zinc absorption unchanged. In a lab model of infant formulas, high- and low-esterified pectin lowered iron availability and high-esterified pectin lowered calcium availability. People with low iron may want to ask a doctor before taking pectin supplements.
- Medicines. Gel fibers such as pectin slow stomach emptying. In a small trial, adding guar gum and pectin to paracetamol slowed its absorption, but the total absorbed was not significantly reduced. A kaolin-pectin suspension prolonged the absorption half-time of clindamycin about 20-fold, from about 16 to more than 300 minutes, without changing the extent of absorption. Ask a pharmacist about timing with medicines. People who take glucose-lowering medicines should ask their doctor too, since pectin can lower the blood sugar rise after a meal.
- Infants. EFSA recommended lower maximum levels of pectin additives in foods for infants under 16 weeks. Do not add pectin to an infant’s feeds without a doctor’s advice.
- Modified citrus pectin. In the prostate study no patient had grade 3 or 4 toxicity, but the study had no comparison group and was sponsored by the product’s developer. Anyone in cancer treatment should ask the treating team before using it.
How to get more pectin
- Eat the fruits and vegetables that carry it. Apples, citrus, bananas and carrots are on the list in the review. At 0.1 to 2.5% of fresh weight, reaching 6 g from produce alone would take 240 g to 6 kg depending on the food (our arithmetic), but they add to total fiber, and 400 g of fruit and vegetables a day is the minimum that FAO and WHO recommend. See our pages on apples and oranges.
- Do not count on jam. High-methoxyl pectin needs more than 55% sugar to gel, and we found no measure of the pectin per spoonful. Fruit gives you the pectin without the added sugar.
- Read supplement labels for grams and type. The EU claim doses are 6 g a day and 10 g in a meal. In the cholesterol trial, a high degree of esterification and high molecular weight worked best. Take pectin with plenty of water.

History of pectin
The name goes back to 1825. A 2022 review credits Louis Nicolas Vauquelin with first isolating pectin from tamarind in 1790, and Henri Braconnot with coining the word in 1825 from the Greek pektikos, meaning to solidify or congeal. Another review credits Braconnot with first extracting it in 1825, in a paper on a new acid found in all plants, so the sources differ on who was first. By the 1990s a review could say that apple pomace and orange peel were the two major sources of commercial pectin, because pectin from other sources gelled poorly.
The health story began with fiber in the 1970s. In 1977 Jenkins and colleagues reported that 10 g of pectin added to marmalade lowered the glucose and insulin rise after breakfast, and in 1979 a Lancet trial linked the effect of gel fibers to slower stomach emptying. In 1982 Judd and Truswell found that 15 g of pectin lowered total cholesterol in 10 young adults. A 1987 review and the 1999 Brown meta-analysis then formed the evidence that EFSA assessed in 2010. The EU authorized the two pectin claims in Regulation (EU) No 432/2012, adopted on 16 May 2012. EFSA re-evaluated pectin as an additive in 2017 and looked again at its use in foods for infants in 2021.

Frequently asked questions about pectin
Does pectin lower cholesterol?
Yes, modestly. A meta-analysis of 67 trials found that each gram of soluble fiber (pectin, oat bran, guar gum or psyllium, 2 to 10 g a day) lowered LDL cholesterol by 0.057 mmol/L. In a crossover trial, 15 g a day of citrus or apple pectin with a degree of esterification of 70 lowered LDL by 7 to 10%, and 6 g a day of citrus pectin by 6 to 7%. FSANZ rated the certainty as moderate and found very little reliable evidence in people with normal cholesterol. The EU allows a cholesterol claim at 6 g a day.
Is pectin good for diarrhea?
It has been tested in children. In 62 infant boys with persistent diarrhea, 59% on a rice diet with pectin had recovered by day 3, against 15% on rice alone. In 255 children with acute diarrhea, a preparation of apple pectin and chamomile extract reduced stool frequency more than placebo, though the pectin cannot be separated from the chamomile. The trials we found were in children, so these results do not tell us about adults.
Is pectin a fiber?
Yes. Pectin is a soluble, gel-forming fiber that sits in the cell walls of fruits and vegetables, and the FDA’s definition of isolated fibers that count names it, as our fiber page explains. Unlike wheat bran it is fermented rather than left as bulk: EFSA describes it as extensively fermented by gut bacteria. It is a close relative of beta-glucan and inulin.
Does pectin help you lose weight?
We found no trial that tested pectin for weight loss. What exists is fullness ratings after single meals. In 74 healthy adults, 5 g or more of pectin in orange juice raised fullness for up to 4 hours, and in 9 obese adults 15 g slowed stomach emptying and raised fullness. Neither trial measured food eaten over time or weight.
What is modified citrus pectin, and does it work?
It is citrus pectin broken into shorter chains and sold as a supplement. In healthy adults, 15 g a day raised urinary arsenic by 130% and cadmium by 150%, but that is a urine test, not a health outcome. In 59 men with prostate cancer that had returned, 75% had a longer PSA doubling time, in a study with no comparison group whose authors include the sponsor’s developer. A placebo-controlled trial found no change in collagen markers. We found no randomized trial showing it treats cancer.
Does pectin cause gas?
It can, because gut bacteria ferment it. After 20 g of pectin, breath hydrogen rose in 4 of 14 men, and whether it did depended on the person’s gut bacteria. In humans, 36 g a day for 6 weeks caused no adverse effects, according to EFSA. Take pectin with plenty of water, because the EU requires a choking warning on pectin claims.
Is the pectin in jam good for you?
Jam contains pectin, but we found no measurement of how much per spoonful, to set against the 6 g or 10 g behind the EU claims. High-methoxyl pectin gels only with more than 55% sugar at a pH below 3.5, so jam is mostly sugar. Fruit gives you pectin without the added sugar.
Is apple pectin better than citrus pectin?
Not in the one trial that compared them. At 15 g a day, citrus and apple pectin with the same degree of esterification (70) lowered LDL cholesterol by the same 7 to 10%, and an orange pulp fiber of the same esterification worked less well. In that trial the degree of esterification and the molecular weight mattered more than the fruit.
