Tag: Niacin vs nicotinamide

According to the National Institutes of Health (NIH), the recommended daily allowance (RDA) for niacin equivalents in adult men is 16 mg and 14 mg for adult women. While this amount is typically met through diet, the safe upper intake level for supplemental nicotinamide is significantly higher, allowing for targeted use in certain contexts.

While most people tolerate nicotinamide well at standard uses, reports indicate that high-dose supplementation may be linked to headaches. It is crucial for those considering or currently taking this form of vitamin B3 to understand the potential side effects and the differences between nicotinamide and other B3 forms.
