Life Extension Buffered Vitamin C Powder, 1 lb (454 g)
UPC: 737870084457
Life Extension's Buffered Vitamin C Powder is a vitamin C supplement formulated for individuals with sensitive digestive systems, aiming to provide antioxidant support without stomach irritation. It contains ascorbic acid buffered with four minerals—calcium, magnesium, zinc, and potassium—which, when mixed with water, create a reduced-acid solution that the manufacturer states is non-irritating to the stomach and intestinal lining. The powder effervesces briefly upon mixing, resulting in a pleasant-tasting drink.
This product is designed to deliver a high dose of vitamin C, with the buffering minerals intended to mitigate the gastric upset that can sometimes accompany standard ascorbic acid supplements. Life Extension notes that it has over 40 years of experience in developing science-backed formulations. The powder is gluten-free, non-GMO, and vegetarian, and it comes in a 1 lb (454 g) container providing approximately 84 servings based on a teaspoon serving size.
