What is Vitamin C? Vitamin C is an essential nutrient that provides support for many areas of your health, including your immune and nervous systems. It can also help to reduce tiredness and fatigue, protect your cells from oxidative stress, and assists collagen formation, helping the normal function of cartilage, skin and bones. But vitamin C is water soluble, meaning the body cannot store it, so it’s important to maintain a regular intake. Why is Healthspan’s better? Vitamin C 1,000mg is the strongest vitamin C supplement in their range. They’ve packed 1,000mg of vitamin C into a convenient one-a-day tablet. That means each tablet provides 1,250% NRV, far above the level of vitamin C required daily to safeguard your health from deficiencies.
