Vitamin C is a powerhouse antioxidant that should be included in every vitamin regimen! Vitamin C in combination with bioflavonoids offers protection against free radical damage, helps keep capillary walls and blood vessels strong, and supports healthy teeth, gums, and bones. Because vitamin C is water soluble it needs to be replenished on a daily basis.
