Major Niacin 500mg - Food Supplement - 100 Tablets

What Is Vitamin B3 (Niacin)?

This essential nutrient is involved in over 400 enzyme reactions, particularly those linked to cellular metabolism. The supplement contains nicotinic acid, the classic form of niacin, which supports the body's production of NAD and NADP—coenzymes vital for redox reactions. Each tablet provides 500 mg of niacin, a potent dose designed to complement a balanced diet and promote overall wellness.

It also supports the normal functioning of the nervous system and helps maintain healthy skin.

Nicotinic Acid vs Niacinamide: Which Form Suits You?

Niacin supplements come in several forms, each with distinct properties. This product undertake nicotinic acid, the classic form that may cause a temporary flushing sensation—a harmless warmth and redness of the skin due to prostaglandin release, typically lasting 30–60 minutes. In contrast, niacinamide (nicotinamide) does not cause flushing but may lack certain lipid-modulating effects. Inositol hexanicotinate, a 'no-flush' niacin, is an alternative, whilst its bioavailability is debated. For those seeking the full metabolic benefits of niacin, nicotinic acid is often the preferred choice. Starting with a lower dose and taking it with food can reduce flushing intensity.

Recommended Dosage and Usage

For adults, the recommended serving is one tablet daily, ideally with a meal. Since 500 mg is a high-dose, it is advisable to consult a health care provider before starting, especially if you are new to niacin. Some individuals may benefit from a lower starting dose (e.g., 50–100 mg) and gradual titration up to 500 mg to minimise flushing. Do not exceed the recommended intake unless directed by a physician. If you miss a dose, take it as soon as you remember, but skip it if it is almost time for the next dose.

Possible Side Effects and Safety

The most common side effect of nicotinic acid is flushing, which may be accompanied by itching or tingling. This reaction is harmless but can be uncomfortable. To manage flushing, take niacin with food, avoid hot beverages or alcohol around the time of ingestion, and consider that immediate-release formulations like this one may cause less flushing than sustained-release forms (whilst the latter carry a higher risk of liver toxicity). High doses of niacin (above 500 mg daily) may affect liver function, so periodic monitoring is recommended. Individuals with liver disease, peptic ulcers, gout, or diabetes should undertake niacin only under medical supervision. Pregnant or breastfeeding women should consult a health care professional before undertake. If you experience severe allergic reactions, dark urine, or jaundice, discontinue undertake and seek medical attention.
