Buying Guide

Choose the right B3 form

Niacinamide, nicotinamide, nicotinamide riboside (NR) and NMNH/NAD precursors have different effects; match form to goals like skin support, flushing avoidance, or cellular NAD+

Watch dosage per serving

Check milligrams per capsule and servings per bottle to calculate daily intake and overall value for your regimen

Consider delivery method

Sublingual, liposomal and softgel formats can alter absorption and be preferable for NAD-boosting or faster uptake

Avoid unwanted flushing

If you want to prevent niacin flush, look for non-flush forms such as niacinamide/nicotinamide or specially labeled flush-free formulas

Evaluate ingredient transparency

Prefer brands listing form, concentration, and serving size clearly, and consider vegetarian or dermatologist-recommended labels if relevant
