Vitamin Biochemistry.


Niacin

"Niacin should be classified with the amino acids since it is made in the body from tryptophan and by definition vitamins cannot be made in the body; this was not known for a while and long usage has placed it in the vitamin camp. If it were thought of as an amino acid the large doses so effective in many diseases would be easier to understand" - A. Hoffer M.D., Ph.D., F.R.C.P.(C),
Negative and Positive Side Effects of Vitamin B3, 2003
