Key Benefits
Vitamin C is an essential nutrient with powerful antioxidant properties. It helps neutralise free radicals, supports collagen formation, enhances iron absorption, and plays a key role in immune defence. While the body relies on vitamin C for numerous functions, it cannot produce it naturally, making supplementation crucial. However, high doses of standard vitamin C can be harsh on the stomach, leading to discomfort in sensitive individuals.
Life Extension’s Buffered Vitamin C Powder delivers 400 mg of vitamin C per serving in a stomach-friendly formula. It combines ascorbic acid with four buffering minerals—calcium, magnesium, zinc, and potassium—to create a reduced-acid solution. This unique blend makes it gentler on the digestive system while supporting overall health. When mixed with water, it produces a mild, effervescent drink that is easy to absorb and pleasant to take.
For over 40 years, Life Extension has been advancing nutritional science, driven by the belief that a healthier and longer life is within everyone's reach.
