Benefits
Antioxidant defense
Apple polyphenols (oligomeric procyanidins) act as antioxidants in laboratory tests. A protective effect on human cells or blood vessels has not been measured for this extract.
Skin support
In a randomized trial, generic apple polyphenols reduced UV-induced skin pigmentation in healthy women. Effects on cardiometabolic markers have not been shown for this extract.
Anti-inflammatory support
Anti-inflammatory activity has been described in laboratory studies. It has not been measured in people taking this extract.
Mechanism of action
Procyanidin antioxidants
Apple procyanidins scavenge free radicals and support the body's antioxidant defenses.
Vascular and metabolic signaling
In laboratory studies, apple polyphenols affect markers of blood-vessel function and of glucose and lipid handling. These are mechanistic findings, not outcomes measured in people taking this extract.
Clinical trials
Randomized, double-blind, placebo-controlled trial of apple polyphenol supplements in healthy women. (Shoji et al. 2020, Nutrients)
Healthy women.
In 65 healthy women, apple polyphenol tablets (300 or 600 mg/day) reduced UV-induced skin pigmentation over 12 weeks versus placebo, with no effect on skin water content or water loss. This was generic apple polyphenol funded by Asahi Breweries, not the Apfenol brand.
