Why Form Matters for Vitamin B3
Not all forms of Vitamin B3 are equal. The form determines how efficiently your body absorbs and uses the nutrient. Lower-quality forms — often found in mass-market supplements — can have dramatically lower bioavailability than premium alternatives.
FormulaForge ranks each form using a 100-point absorption score that combines peer-reviewed bioavailability percentage, formulary standing, relative multiplier versus the gold-standard form, and our bioavailability classification. Preferred forms represent the best available evidence for absorption efficiency.
