For high cholesterol, 300-1,2000 milligrams of niacin has been taken by mouth daily for 6-44 weeks as wax-matrix, immediate-release (crystalline); 2 grams of niacin has been injected into the vein over 11 hours. The maximum recommended daily dose is 3 grams.
The daily niacin requirement varies with the number of calories burned daily (the energy expenditure) and the protein intake. One niacin equivalent equals 1 mg of preformed niacin or 60 mg of dietary tryptophan. Niacin can be synthesized in the body from the essential amino acid tryptophan.Tissues can form an average of I mg of niacin from 60 mg of tryptophan provided by dietary protein. Consequently a high-quality protein diet supplies substantial tryptophan for niacin synthesis.he daily niacin requirement varies with the number of calories burned daily (the energy expenditure) and the protein intake.
