What is Niacin?

Niacin is a Vitamin supplement available in 1 form.

FormulaForge carries a single form of Niacin, so there is no form to choose here. Forms on the market do differ in how well they absorb, which is why it is worth checking the form named on any product label.

The Form of Niacin We Carry

Nicotinic Acid (Niacin) (Secondary Form) has a bioavailability rating of good absorption.

What the Research Shows

Niacin (nicotinic acid, vitamin B3) is the flush-causing form of B3 with robust evidence for lipid management — it is the only nutrient that meaningfully raises HDL cholesterol. Unlike niacinamide, niacin activates the GPR109A receptor, triggering vasodilation (flushing) and supporting lipid transport. Multiple large-scale trials support its cardiovascular benefits.

How to Choose the Right Form

Multiple forms of Niacin are available. Start by comparing form ratings — Preferred Forms reflect the strongest bioavailability evidence, and higher-absorption forms deliver more active compound per dose unit.

The appropriate form depends on your individual goals and your healthcare provider’s recommendations. Consult a qualified professional before selecting a supplement form.

Dosing & Safety

Individual dose requirements vary based on health goals, body weight, and existing nutrient intake. Your healthcare provider can help you determine an appropriate amount of Niacin for you.

Side Effects: Consult your healthcare provider regarding tolerability, particularly at higher doses.
