Vitamin C is one of the leading vitamins for immune support, and for good reason.** It is essential for the optimal functioning of white blood cells, and is a potent antioxidant that helps to fight free radicals.** It also helps to regenerate vitamin E to their active state to maintain antioxidant support.** Unlike most other animals, humans cannot synthesize their own vitamin C so it must be obtained from dietary sources. As a water soluble vitamin, it cannot be readily stored in the body. This means adequate amounts of vitamin C should be consumed every day.
The Recommended Dietary Allowance (RDA) for adults is between 75-90 mg per day depending on gender, but some experts recommend a daily intake of at least 200 mg per day for healthy individuals. 3
National survey data indicates Americans are not meeting the recommendations for daily fruit and vegetable intake, resulting in a significant prevalence of about 40% of Americans with inadequate dietary intake of vitamin C.1 A study gave subjects either regular Vitamin C or a specialized form of Vitamin C known as Ester-C®.2 Results found that Vitamin C from Ester-C® stayed in the white blood cells for up to 24 hours, which was longer than regular Vitamin C. White blood cells are an important part of the immune system.
