NutriBiotic Calcium Ascorbate is a fully reacted, buffered comp0und combining vitamin C and calcium in a highly soluble form.

Vitamin C is an essential nutrient that cannot be produced by the body and, therefore, must be replenished daily. Vitamins C has several beneficial purposes including developing and maintaining healthy skin and bones and plays important roles in many biochemical reactions. Vitamin C provides support to the body's immune system by protection cells from oxidative stresses.

Calcium helps maintain bone density. Adequate calcium as part of a healthy diet, along with physical activity, may reduce the risk of osteoporosis in later life. Calcium not only serves as the principle component of skeletal tissue, but also plays a vital role in many bodily functions.

Suggested Use

Mix 1/2 teaspoon or more into a glass of juice or water. Take with or without meals, or as directed by a licensed healthcare professional.

Vitamin C for Everything

Posted by Reviewer1434258 on Feb 25, 2014

Dr. Paul Levy has written a book, "Curing the Incurable", which says it all about C. Calcium ascorbate C is gentle on the stomach and allows large doses to be taken. I have taken 20 grams for food poisoning, and been normal within 2 hours. Nutribiotics web site explains how they completely react their calcium ascorbate to make a very safe and effective form of vitamin C, for those who want the benefits described in Dr. Levy's book. Vitamin C has a bad habit of working.

Non-gmo. My dogs take it.

Posted by Reviewer1841085 on Jan 07, 2014

This dissolves well with a few seconds of vigorous stirring. The taste is not gag-worthy. I purchase this brand because it lasts a while, is non-gmo, and is in one of the best non-acidic forms. I give two doses to my dogs daily in their Honest kitchen.

Great Vitamin C

Posted by Reviewer2781861 on Sep 02, 2012

I use this Vitamin C. It dissolves well and the taste is not bad. I do add fresh lemon to it when I use it just because I enjoy the lemon flavor.
