Product Overview


  • Foundation for Longer Life
  • Vitamin C for Sensitive Stomachs
  • Dietary Supplement

Vitamin C, or ascorbic acid, is a white, crystalline, water-soluble substance found in citrus fruits. As an antioxidant, vitamin C scavenges free radicals in the body and protects tissues from oxidative stress. Vitamin C also promotes the absorption of iron, while preventing its oxidation. Vitamin C is a vital cofactor to the formation of collagen, the connective tissue that supports arterial walls, skin, bones, and teeth. A major immune-supporting activity of vitamin C is boosting glutathione levels in human lymphocytes, cells that make up about 25% of all white cells in the blood.

More vitamin C is contained in the adrenal glands than any other organ in the body and is required at higher levels during times of stress. Physical stresses on the body such as ingestion of heavy metals, cigarette smoking, immune impairment, extreme temperatures, and chronic use of certain medications such as aspirin also signal the need for increased intake of vitamin C.

Vitamin C Powder contains four buffering minerals, in addition to ascorbic acid. When mixed with water, this product produces a reduced-acid solution that is non-irritating to the stomach and intestinal lining. The minerals also make it a more pleasant-tasting and healthful drink. The substances used in this product make it effervesce for a short while when it is mixed with water.

Suggested Use

Read the entire label and follow the directions carefully prior to use.

Mix one (1) teaspoon of Buffered Vitamin C Powder into a glass of water. Wait for the fizz to stop before consuming. The minerals buffer out the normally acidic vitamin C to make a pleasant tasting drink.

Other Ingredients

great added to my smoothies

Posted by iHerb Customer on Aug 12, 2017 | Verified Purchase

Easily absorbed and I like to add to my smoothie to give extra boost along with my greens .

Thanks for your feedback!

Nice balanced formula

Posted by iHerb Customer on Jul 19, 2017 | Verified Purchase

I don't use a full teaspoon, more like 1/4 for maintenance. If I feel aches or sore throat coming on, I increase the dosage, plus use NAC. No infections for years.

Thanks for your feedback!

Vit C

I have found this to be a very good vit c for me..

Thanks for your feedback!

Definitely NOT a "pleasant tasting drink" - one star because I can't select zero stars

Posted by iHerb Customer on Jan 12, 2017 | Verified Purchase

Tastes disgusting! Taste can only be disguised by adding to smoothies with strong flavours and/or magnesium powder which seems to hide the soapy taste sufficiently. Each time I've only taken 1 rounded teaspoon as recommended and have had the worst digestive discomfort all day! This might be a suitable product if you a) have perfect digestive health, and b) can stomach gross, soapy drinks...but otherwise stick to the usual Vitamin C tablets or powder!!! Wish I hadn't wasted my money!

Thanks for your feedback!
