Key Benefits and Actions*

  • With natural supportive bioflavonoids
  • May help support a healthy immune system
  • May help support healthy eyes and skin
  • May help support cardiovascular health

Optimal Vitamin C Powder by Seeking Health provides over 2,500 mg of vitamin C in a great-tasting effervescent powder. This important antioxidant may help support the immune system, healthy connective tissue and skin and normal levels of glutathione within the body. As an antioxidant, vitamin C may protect cells from the damage caused by free radicals. Free radicals are compounds formed as normal products of metabolism and in response to environmental exposures. We are exposed to free radicals each day in the environment from cigarette smoke, air pollution, and ultraviolet light from the sun. In addition to supporting the body’s healthy response to these exposures, the body also needs vitamin C to make collagen, a protein required to help wounds heal.*

Optimal Vitamin C Plus features antioxidant- and immune-supportive bioflavonoids quercetin, rutin and hesperidin. These are naturally occurring bioflavonoids found in citrus fruits. Quercetin is also found in red wine and tea. It is sweetened with stevia, without fructose or other undesirable sweeteners. When added to water, the powder turns into a delicious fizzy drink, making it easy for kids or others with finicky palates to use.*

Also try our Optimal Liposomal Vitamin C, providing 1000 mg of vitamin C per serving with an advanced liposomal delivery format to facilitate optimal absorption.*
