Niacin (Vitamin B3)

Supportive evidenceEveningConditional

Best for: Healthy aging

Dose & timing

Dose
General-adequacy doses are 14–16 mg daily. Lipid-modifying doses (1–2 g) require clinician oversight, monitored liver enzymes, and immediate-release form only — sustained-release niacin at gram-scale doses has caused hepatotoxicity and is not recommended.
Timing
Evening with food to mute flushing.
Review
Reassess after 8 weeks with lipid panel and liver enzymes.
Forms
immediate-release niacin

What this supplement is for

  • Real lipid signal at gram-scale doses; not appropriate without clinician oversight.
  • Cardiovascular outcomes data is mixed despite the lipid effects (AIM-HIGH, HPS2-THRIVE).
  • Sustained-release forms have a documented hepatotoxicity signal at lipid doses; this engine never auto-recommends gram-scale niacin without clinician routing.

Cautions

2 flagged
  • Avoid if you have a history of liver issues.
  • Check for interactions if you take prescription medication.

What to look for in a product

  • Preferred third-party verification: USP Verified.
  • Common contamination risks: Mislabeling / identity.
  • Form: Immediate-release niacin has the lipid evidence but causes flushing. Sustained-release forms have hepatotoxicity risk.

Talk to a clinician first

Gated

This is a supplement we won’t link to a specific product without clinician context. Hepatotoxicity risk with sustained-release forms; flushing causes confusion with allergic reactions.Once we offer clinician partner pathways, this is where they’ll appear.

If you’re working with a doctor or qualified practitioner, they can advise on dose, brand, and monitoring.
