A polyphenol-rich botanical included for general antioxidant support.
Grape skin extract brings polyphenols to the formula, a category of plant compounds commonly included in wellness products for antioxidant support. It works alongside pine bark extract to round out the formula's broader antioxidant profile rather than standing alone as a single active.
Grape Skin Extract is one of eight ingredients named openly on the HoneyFil label — no vague "proprietary blend" wording anywhere. As with the rest of the formula, we don't attach a specific milligram figure to it, since that number isn't part of the publicly available material we were able to review; your bottle's Supplement Facts panel remains the accurate source.
