Should I take Vitamin B3 (niacin / nicotinamide)?

This is not personalized medical advice. Our file highlights plausible help contexts (Lipid management (prescription niacin era) NAD+ marketing adjacency) and caution contexts (Anyone replacing prescribed therapy without medical supervision Undiagnosed severe symptoms (chest pain, GI bleeding, sudden neurologic changes)). RDA ~14-16 mg NE/day; immediate-release niacin flush doses often 100-500+ mg - hepatotoxicity risk at high sustained doses. (typical supplement-label context, not individualized dosing).
