Product Overview


  • Where Science Works Naturally
  • Pharmaceutical Grade
  • Dietary Supplement
  • pH 2.1‡
  • Naturally Fresh Nitro Pak Bacteria Free Environment
  • Highly Soluble

    NutriBiotic Ascorbic Acid is 100% pharmaceutical grade vitamin C, an essential nutrient beneficial to the body's overall health. This highly soluble form of vitamin C provides antioxidant protection to the immune system. It has several purposes including maintaining and developing health bones and tissue, and plays important roles in many biochemical reactions. Since vitamin C is not produced by the body, it must be replenished daily.

    Very affordable

    Posted by iHerb Customer on March 22 2018 | Verified Purchase

    We take high dose vitamin C and this is a very affordable way to take it. One 5lb container lasts our family approximately 9 months

    Thanks for your feedback!

    Excellent !!!

    I have tried several brands of Vitamin C (Ascorbic Acid), this is one of the best grade product. Refine crystal grains, easily dissolve and taste not so sour

    Thanks for your feedback!

    We have been using this for years and it has been a wonder at the results! I take very high doses each day and have been able to completely stop taking my asthma maintenance inhaler and Singulair plus I could stop taking allergy shots after 30 years! We use this daily and we don't get sick like we used to and if we do we just increase our intake and it shortens the duration. Also great anti inflammatory product for arthritis or injuries. Best product ever if you want a natural remedy instead of harmful prescription drugs that have such horrible side effects.

    Thanks for your feedback!

    So sour it's hard to take consistently

    Posted by iHerb Customer on September 10 2017 | Verified Purchase

    I bought it after reading reviews regarding its taste but boy were the reviewers generous. 1 teaspoon in 250ml of water and I can't even tolerate that. No chance for my kids to use it. Probably wasted the whole tub unless I can mix it in something to mask the taste

    Thanks for your feedback!

    Always Good.
