SUPERIOR IMMUNE BOOST. Vitamin C is vital for immune support, playing an important role when it comes to helping your body fight off infection by supporting the production of antibodies that latch onto invading microbes to neutralize them. Solaray Vitamin C's clean, Non-GMO formula gives you 1,000 mg of Vitamin C in each lab-verified liquid capsule, that's 1,667% your daily value of Vitamin C from our proprietary blend of Ascorbic Acid, Acerola, and Rosehips. FAST ACTING, LONG LASTING. This time release formula is designed to release half of the Vitamin C into your body rapidly and the other half gradually over a period of up to 12 hours, which may help extend the availability of Vitamin C for a longer period of time. SKIN AND COLLAGEN SUPPORT. Vitamin C is great for boosting immunity, but you also get help with the synthesis of collagen, the absorption of iron, wound healing, and the maintenance of cartilage, bones and teeth.
