Optimized Quercetin from Life Extension comes in a pack of 60 vegetarian capsules, each delivering 250 mg of quercetin dihydrate alongside a 210 mg food blend of citrus bioflavonoids, apple, and onion extracts. Vitamin C (30 mg per capsule, sourced from ascorbic acid and wildcrafted camu-camu berry extract, 60 mg) rounds out the formula, making this a thoughtfully composed bioflavonoid supplement in a single daily capsule format.
Quercetin is a naturally occurring bioflavonoid present in red onions, apples, red grape skins, and buckwheat. Here it is supplied as quercetin dihydrate, a form chosen for its bioavailability, and paired with complementary whole-food-derived ingredients rather than delivered in isolation. Each capsule is suitable for vegetarians.
This product appeals to those who follow a plant-rich diet and want a supplement that reflects similar food-source ingredients in concentrated capsule form. It is equally well suited to athletes and health-conscious adults looking to add a recognised bioflavonoid to their daily stack without unnecessary fillers or additives.
