What Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Insulin
In healthy adults, taking 900-1800 mg of a polyphenol-rich apple extract prior to a meal delays the time to peak postprandial blood glucose levels. Theoretically, apple polyphenols might have additive effects when used concomitantly with certain insulin products and may increase the risk of hypoglycemia. Monitor blood glucose levels closely. Timing of insulin administration may need to be adjusted.
Apple Polyphenols: Uses, Safety & Side Effects
Apple polyphenols are antioxidant plant compounds taken from apples and marketed for heart, weight, and blood sugar health. Early research is interesting, but there is not enough reliable human evidence to confirm these benefits. They appear generally safe in food-like amounts, but talk with your pharmacist or doctor before using concentrated supplements.

Overview
Apple polyphenols are natural plant compounds (phytochemicals) found in apples, especially in the peel and in unripe fruit. They are concentrated and sold as supplements made from apple extract.
Apples come from the apple tree, Malus domestica, which is grown around the world in temperate climates. The fruit naturally contains a mix of polyphenols such as chlorogenic acid, phlorizin, phloretin, epicatechin, procyanidins, quercetin, and kaempferol.
People take apple polyphenol supplements hoping to support heart health, manage weight, lower blood sugar, and get general antioxidant benefits. Some products are also used on the skin.
How it works
Apple polyphenols are studied mainly for their antioxidant activity, meaning they may help reduce damage from unstable molecules called free radicals.
The mix of compounds includes procyanidins, epicatechin, chlorogenic acid, quercetin, phloretin, and phlorizin. In laboratory and animal research, some of these compounds appear to affect how the body handles fats and sugar. For example, phlorizin has been studied for blocking sugar absorption in the gut, and certain polyphenols may have anti-inflammatory effects.
It is important to know that much of this research comes from test tube and animal studies, not large human trials. So these mechanisms are best seen as proposed explanations, not proven effects in people.
Does Apple Polyphenols work?
How to read these evidence grades
Natural Medicines’ 7-point scale. We show each rating’s label word-for-word.
For Apple Polyphenols, current evidence isn’t strong enough to rate any specific use. The conditions it has been studied for are listed below.
Also studied for 6 conditions — evidence insufficient to rate
Insufficient Reliable Evidence To Rate Allergic rhinitis (hay fever)
Preliminary clinical research in adults with moderate or severe persistent allergic rhinitis due to dust mite allergy shows that taking a specific supplement (Applephenon, Asahi Food and Healthcare Ltd) containing apple polyphenols 50 mg or 200 mg in a drink daily for 4 weeks reduces the frequency of sneezing attacks when compared with placebo. The higher 200 mg dose also reduces nasal discharge when compared with placebo. Preliminary clinical research in patients with allergic rhinitis caused by Japanese cedar shows that taking apple polyphenol 500 mg once daily for 12 weeks, beginning about 2 weeks prior to cedar pollen dispersion, reduces sneezing, but not symptoms such as rhinorrhea and eye itching, when compared with placebo.
Insufficient Reliable Evidence To Rate Androgenic alopecia
Preliminary clinical research in adults with male pattern baldness shows that applying 1.8 mL of apple polyphenol procyanidin 0.7% to 1% twice daily to the scalp for 6-12 months increases hair growth when compared with placebo.
Insufficient Reliable Evidence To Rate Athletic performance
Clinical research in healthy physically active males shows that taking a specific supplement (Vinitrox, Nexira) containing 500 mg apple and grape polyphenols two times prior to an endurance test results in a 10% increase in time to exhaustion, or about 3 additional minutes, when compared with placebo. However, there were no differences between groups in recovery time and muscle pain.
Insufficient Reliable Evidence To Rate Hyperlipidemia
Preliminary clinical research in adults with hyperlipidemia shows that consuming lyophilized apples containing polyphenols 1.43 grams daily for 4 weeks does not affect cholesterol levels or brachial artery flow-mediated vasodilation (FMD) when compared with consuming apples containing polyphenols 0.21 grams. However, other preliminary clinical research shows that taking 2 capsules of a specific supplement (AppleMetS) containing 400 mg of apple polyphenolic extract per capsule daily for 8 weeks reduces low-density lipoprotein (LDL) cholesterol levels and increases high-density lipoprotein (HDL) cholesterol levels in patients with hyperlipidemia when compared to baseline. The validity of these findings is limited by the lack of a comparator group.
Insufficient Reliable Evidence To Rate Hypertension
Preliminary clinical research in patients with hypertension or borderline hypertension shows that taking an apple polyphenol extract 330 mg daily for 4 weeks does not improve blood pressure or endothelial function, as measured by flow-mediated vasodilation (FMD), when compared with placebo. However, given the small study size and that blood pressure was a secondary endpoint, it is likely the study was not adequately powered to detect a difference between groups.
Insufficient Reliable Evidence To Rate Obesity
Clinical research in healthy, overweight adults shows that drinking a beverage containing 600 mg of a specific apple polyphenol product (Applephenon, Asahi Food and Healthcare, Ltd.) daily for 12 weeks reduces total fat when compared with placebo. Additional clinical research in adults with a body mass index (BMI) in the range of 23-30 shows that taking apple polyphenol 600 mg before dinner for 12 weeks reduces visceral fat when compared to control.

Where Natural Medicines hasn’t rated a use, HelloPharmacist’s pharmacists may add their own reviewed rating and evidence (each such entry is labeled). This is educational information, not medical advice — talk with your pharmacist or doctor before starting, stopping, or changing a supplement.
Safety & precautions
Apples as a food are widely eaten and considered safe. Apple polyphenols as a concentrated supplement appear to be generally well tolerated when used by mouth for the short term, but long-term safety is not well studied.
People with allergies to apples should avoid these products. If you have a medical condition or take prescription medicines, check with your pharmacist or doctor before starting a supplement.
For pregnancy and breastfeeding, eating apples is fine, but concentrated extracts have not been properly studied. To be safe, avoid apple polyphenol supplements during pregnancy and breastfeeding unless your healthcare provider says otherwise.
Side effects
Apple polyphenol supplements are usually well tolerated. When side effects occur, they tend to be mild and may include stomach upset, gas, or bloating.
Allergic reactions are possible in people sensitive to apples. Serious side effects have not been commonly reported, but because long-term human data are limited, it is wise to start with a low amount and watch how your body responds.

Cluster headache Neurologic/CNS
Orally, taking apple polyphenols may cause headache in some patients. In one clinical trial, around 26% of patients taking apple polyphenols 330 mg daily for 4 weeks reported headaches, although this adverse effect was also reported in nearly 24% of patients taking placebo.
Diarrhea Gastrointestinal
Orally, taking 600 mg apple polyphenols was reported to cause diarrhea and loose stools in one clinical study.
Myasthenia gravis Pulmonary/Respiratory
Orally, taking apple polyphenols might cause nasopharyngitis in some patients. In one clinical trial, 8.6% of patients taking apple polyphenols 330 mg daily for 4 weeks experienced nasopharyngitis. This adverse effect was also reported in 5.1% of patients taking placebo.

Dosing
There is no standardized, well-established dose for apple polyphenols. Products vary widely in how much polyphenol they contain.
The best approach is to follow the directions on the product label and not exceed the suggested amount. Because doses and product quality differ, talk with your pharmacist or doctor before starting, especially if you have a health condition or take other medicines.
