“This best grape seed extract supplement is the best one we tested. In terms of quality, brand and price, we couldn't ask for more.”

Main Highlights

OUTSTANDING VALUE: Our Extra Strength Grape Seed Extract contains 20,000 mg strength per capsule, is standardized to 95% Polyphenols, AND contains 180 capsules per bottle an amazing value! A single bottle contains a 6 month supply. Compare this to other leading brands that require 2 capsules per serving, contain less than 180 capsules, and use a much less potent, non-extract powder. Our Extra Strength Grape Seed Extract is a bargain not be found elsewhere!
95% POLYPHENOLS: Polyphenols are the good stuff, the beneficial compound in Grape Seed Extract that provides the desired results. Our Grape Seed Extract has been standardized to contain a minimum of 95% Polyphenols, which is one of the highest standardization numbers available. The higher the numbers, the more potent the extract. Clearly, not all Grape Seed Extracts are created equal!
POTENT 50:1 EXTRACT / 20,000 MG STRENGTH PER CAPSULE / HIGH BIOAVAILABILITY: Each capsule contains 20,000 mg strength of Grape Seed Extract from a potent, powerful 50:1 extract. Combine that with a minimum of 95% Polyphenols, and our Extra Strength Grape Seed Extract is one of the strongest dosages available! The key to our extraction is an all-natural process that ensures high bioavailablity - which means your body receives maximum absorption and maximum benefits.
NATURAL, VEGAN & NON-GMO: All ingredients, including the capsule, are 100% vegan. Our Extra Strength Grape Seed Extract does not contain any sweeteners, artificial flavors, wheat, corn, gluten, soy, milk, egg, fish, shellfish, or tree nut ingredients. Enjoy the amazing benefits of our potent Grape Seed Extract without worrying about what else might be hiding in each capsule!

For that reason, our Extra Strength Grape Seed Extract is manufactured in the USA, in a fully certified facility with adherence to good manufacturing policies and under the most stringent quality control.
