Not All Vitamin C Products Are Created Equal For your body to truly get all the benefits of vitamin C, it needs to get it from more than one source. Vitamin C⁸ combines calcium, magnesium, potassium, zinc, manganese, selenium, and sodium mineral ascorbates with ascorbyl palmitate to provide a full spectrum of powerful antioxidant benefits. Only Vitamin C⁸ offers eight assisted pathways of absorption and retention for 24 hours or more. Vitamin C⁸ does even more for your health: Vitamin C⁸ helps enhance your immune strength and is an excellent source of electrolytes which can replenish those lost through perspiration. It also delivers the antioxidant action of three cups worth of green tea per capsule.
