Red Grape Skin Extract

Yes, red grape skin is one of nature's most concentrated sources of beneficial polyphenols and resveratrol. These compounds have been linked to heart health, antioxidant protection, and anti-inflammatory effects. Mega Resveratrol's extract captures these benefits in a concentrated, excipient-free capsule form with standardized 25% polyphenol and 1.5% Piceid content per serving.

Each 500mg capsule contains 25% polyphenols (100mg) and 1.5% Piceid resveratrol (7.5mg). The product also delivers 10% trans-resveratrol at 50mg per capsule. No excipients, fillers, or binders are included — just pure red grape skin extract encapsulated for maximum potency and clean supplementation.

Yes. The product is certified non-GMO, gluten-free, and pesticide-free. It contains zero synthetic ingredients and no excipients of any kind. It is manufactured in the USA in a GMP-certified, FDA-regulated facility and undergoes independent third-party laboratory testing to verify purity before each batch is released.

Red grape skin extract is water-soluble, offering significantly higher bioavailability and absorption compared to trans-resveratrol derived from Japanese Knotweed. The grape skin source also provides a natural matrix of polyphenols alongside Piceid resveratrol, making it a more comprehensive cardiovascular supplement. Knotweed-derived products typically offer higher trans-resveratrol concentrations but lack this broader polyphenol profile.

The suggested serving is 1 to 4 capsules daily, each containing 500mg of red grape skin extract. Most users seeking cardiovascular support take 1 to 2 capsules per day, providing 100 to 200mg of trans-resveratrol equivalent. Consult your healthcare provider to determine the optimal dosage for your individual health goals and medical history.
