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 buffered 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 features antioxidant- and immune-supportive bioflavonoids quercetin, rutin and hesperidin. These are all naturally occurring bioflavonoids found in citrus fruits. Quercetin is also found in red wine and tea. Our vitamin C is buffered with calcium and magnesium, making this product a gentler vitamin C option than other powders on the market. It is sweetened with stevia extract, 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.*

More than just vitamin C

I love adding this with the seltzer electrolytes! Win-win and honestly, this is more than just vitamin C! It has important extras like Quercetin to help its efficacy even more.

Love this stuff!

I have people counting on me to take care of them so I do everything in my power to boost my immune system. I had heard that sipping vitamin C all day was a good idea. For the last year I have been adding seeking health Vitamjn C powder to every glass of water I drink during the day. I order the 3 pack on auto ship, I love the flavor... one of daughters love’s it and one hates it.

Recently I was exposed to several people who had a virus and everyone got sick...really sick, I also felt under the weather but never had to even spend one day in bed. I believe that’s because I do all the things as a prophylactic vitamin C in my water, glutathione, immune intensive, zinc, vitamin D and more.
