Coenzyme for a number of hydroxylation reactions; required for collagen synthesis. Widely distributed in plants and animals. Most primates (including humans), guinea pigs, and some birds and fish cannot synthesize ascorbic acid. Inadequate intake results in deficiency syndromes such as scurvy.” The second product, Chondroitin Sulfate Sodium, aka Chondroitin, hydrogen sulfate, sodium salt, is the sodium salt of the sulfated, linear glycosaminoglycan obtained from the dried, pulverized, and purified cartilage of healthy and domesticated animals (e.g., cows, pigs, and chickens) that are used for food by humans. You indicate in your letter that the product will be used in the manufacture of dietary supplements.
