How to Choose Niacin
The current Niacin rule incorrectly includes the generic Vitamin B tag, producing many unrelated products. Require label-disclosed niacin or vitamin B3 and distinguish standalone niacin from B-complex formulas.
Niacin forms and amounts differ, and higher-dose nicotinic acid may cause flushing and other adverse effects. Review directions, medication and liver considerations, laboratory monitoring, and qualified healthcare guidance.
