Product Overview


  • Where Science Works Naturally
  • Pharmaceutical Grade
  • Dietary Supplement

Highly Soluble

NutriBiotic Ascorbic Acid with Antioxidant Bioflavonoids delivers 100% pharmaceutical grade vitamin C, an essential nutrient beneficial to the body's overall health, and antioxidant bioflavonoids from lemon in a highly soluble form.

Since vitamin C is not produced by the body, it must be replenished daily. Vitamin C is often found in nature accompanied by bioflavonoids, a group of water-soluble plant pigments. Bioflavonoids work synergistically with vitamin C in the body to play an important role supporting numerous biochemical reactions, such as normal fluid balance, the function of various enzyme systems, tissue growth and repair, and strengthening the walls of blood vessels.

NutriBiotic Ascorbic Acid with Antioxidant Bioflavonoids is well tolerated by most highly allergic individuals.

Suggested Use

As a dietary supplement, mix 1 teaspoon or more into a glass of juice of water. Take with or without meals, or as directed by a licensed healthcare professional.

Pure pharmaceutical-grade Vitamin C with bioflavonoids

Posted by Reviewer2238935 on Nov 08, 2016

The brownish color puts some people off (I believe that's from the bioflavonoids; the plain Ascorbic Acid is pure white) but I love the fact that this C is pharmaceutical grade, pure, with nothing else in it but bioflavs. And I especially like that I can get those bioflavs without the addition of buffering minerals like calcium which are not so good to take at the same time as thyroid medication. This C is not as good to mix with juice as the plain version (kind of ruins the flavor of the liquid its put in) so I mix in water. Great for when you feel a cold coming on and want to take large doses to reach bowel tolerance without having to take lots of Vitamin C pills. I hope they never stop making it and that iHerb will keep selling it at a reasonable price!

Lovely product. Handy to have the bioflavonoids added when you don't have fresh lemons on hand.
