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 DRIs for niacin are reported in niacin equivalents (NE) because niacin can be synthesized by the body from tryptophan. The RDA is 14 mg NE for women and 16 mg NE for men. The UL is 35 mg NE/day for adults. Niacin deficiency (pellagra) is not common in the United States.
