Niacin (vitamin B3) capsules 50 mg to 1000 mg as nicotinic acid, nicotinamide or inositol hexanicotinate, sold as supplements in most markets, for importers, distributors and private-label brand owners.

Product Description:

Niacin, or vitamin B3, is a water-soluble B vitamin. The body turns it into the coenzymes NAD and NADP, which take part in hundreds of energy-releasing reactions. The name covers several forms. Nicotinic acid is the classic form and often causes a warm skin flush at higher amounts. Nicotinamide, also called niacinamide, does not flush. Inositol hexanicotinate is sold as a no-flush form with nicotinic acid bound to inositol. This page covers capsules from 50 mg to 1000 mg, and the form defines the product as much as the strength.

Niacin capsules are sold in most markets as food or dietary supplements, labelled with niacin per serving. Many authorities set an upper intake level, and some cap the amount allowed per daily dose, so the higher strengths here may not fit the supplement category everywhere. In some markets, high-dose modified-release nicotinic acid is a registered prescription medicine, used under medical supervision because of flushing and effects on liver tests and blood sugar. People on regular medicines should ask a pharmacist first.

Sourcing notes. State the form you need (nicotinic acid, nicotinamide or inositol hexanicotinate), the strength per capsule and whether the label claim is for the compound or niacin equivalent. Ask for a CoA per batch with assay by a validated method, content uniformity, heavy metals, residual solvents and microbial limits. Confirm the shell type, gelatin or plant-based, with halal or kosher certificates if needed, and a GMP or food-safety certificate for the plant. Moisture-protective bottles or blisters suit room-temperature storage. Confirm each strength's category in your market.
