Buying Guide

Choose the right form of B3

Niacinamide (nicotinamide), niacin (nicotinic acid), and NAD precursors like NMNH differ in effects—niacin can cause a flush, niacinamide is flush-free, and NMNH targets cellular NAD+ pathways

Consider delivery method

Capsules, sublingual NAD precursors, and vegan formulations affect absorption and convenience—pick the form that fits your routine and tolerability

Check formulation and additional ingredients

Some supplements combine niacin with antioxidants or branded extracts; verify additive ingredients if you have allergies or are taking other therapies

Verify brand transparency and review signals

Prioritize products with clear labeling (dosage per capsule, vegetarian/vegan claims) and substantial, consistent user ratings to gauge real-world tolerability
