A member asked:
How much niacinamide can i take daily without risking liver damage?
A doctor has provided 1 answer
A large amount: The upper limit of the dose of niacinamide is over 3 grams. Most patients don't need nearly that much or can't take that much due to side effects such as flushing or diarrhea. Niacin is a B vitamin and thus is water soluble. It is extremely hard to overdose on Niacinamide and damage your liver.
