Major Niacin 500 mg - Dietary Supplement - 100 Tablets

How to Choose a Quality Niacin Supplement in Australia

When selecting a niacin supplement, it's important to consider the form, dosage, and manufacturing standards. Major Pharmaceuticals sticks to strict regulatory compliance, so each tablet meets high quality and purity standards. Third-party testing by organisations like TGA or independent labs gives extra peace of mind. Look for supplements that clearly list the active ingredient (here, 500 mg nicotinic acid) and avoid unnecessary fillers or additives. This product is non-GM and Gluten Free, suitable for many diets. Always check the expiry date and store tablets in a cool, dry place away from sunlight.

Recommended Dosage and How to Take Niacin

For adults, take one tablet daily, preferably with a meal. Since 500 mg is a strong dose, it's wise to consult your health care provider before starting, especially if you're new to niacin. Some folks might start with a lower dose (like 50–100 mg) and gradually increase to 500 mg to reduce flushing. Don't exceed the recommended intake unless your doctor says so. Niacin absorbs best with food to minimize stomach upset. If you miss a dose, take it as soon as you remember, but skip it if it's nearly time for the next one.

Health Benefits of Niacin Supplements

Niacin helps maintain healthy functions of the nervous system, digestive system, and skin. It contributes to normal energy-yielding metabolism, breaking down carbs, fats, and proteins efficiently. The skin benefits from niacin's role in cellular regeneration and maintaining the skin barrier. Your nervous system relies on niacin for proper nerve signalling and neurotransmitter production. Many people use niacin to support healthy cholesterol levels already within normal range. Research suggests niacin may raise HDL ("good") cholesterol and support healthy triglycerides. These effects are best managed under medical supervision, especially at higher doses.

Niacin vs Niacinamide – Which Form Should You Choose?

Niacin supplements come in different forms, each with unique properties. This product uses nicotinic acid, the classic form that may cause a temporary flush—a harmless warmth and redness of the skin. This flush comes from prostaglandin release and usually fades within 30–60 minutes. In contrast, niacinamide (nicotinamide) doesn't cause flushing but lacks certain lipid-modulating effects. Inositol hexanicotinate, a "no-flush" niacin, is another option, though its bioavailability is debated. If you want the full metabolic benefits and can handle the flush, nicotinic acid is often the preferred choice. Starting with a lower dose and taking it with food can reduce flushing intensity.

Potential Side Effects and Safety Considerations

The most common side effect of nicotinic acid is a flush, sometimes with itching or tingling. This reaction is harmless but can be uncomfortable. To manage it, take niacin with food, avoid hot drinks or alcohol around the time, or use this immediate-release form (flushing tends to be less severe with sustained-release forms, but liver toxicity risk is higher). High doses (over 500 mg daily) may affect liver function, so periodic monitoring is recommended. People with liver disease, peptic ulcers, gout, or diabetes should only use niacin under medical supervision. Pregnant or breast-feeding women's should consult a healthcare professional. If you experience severe allergic reactions, dark urine, or jaundice, stop use and seek medical help.

What Is Vitamin B3 (Niacin)?

Vitamin B3, commonly called niacin, is a water-soluble B vitamin essential for turning food into energy. It plays a critical role in the function of over 400 enzymes, especially those involved in cellular metabolism. Niacin comes in two main forms: nicotinic acid (used in this supplement) and niacinamide. Both support the body's production of NAD and NADP—coenzymes vital for redox reactions—but nicotinic acid is known for its ability to promote healthy circulation and lipid metabolism. This product provides 500 mg of niacin per tablet as niacin acid, a potent dose that supports various physiological processes. It's designed to fill nutritional gaps and promote overall wellbeing as part of a balanced diet.

Can I take niacin on an empty stomach?

It's best to take niacin with food to reduce the chance of flushing and stomach upset. Taking it on an empty stomach may make the flush worse.

How long does it take for niacin to work for energy?

Niacin supports energy metabolism at the cellular level, so benefits may appear within a few days to weeks, depending on your diet and health.

Is 500 mg of niacin too much?

The recommended dietary allowance for niacin is 16 mg for men and 14 mg for women's. Doses of 500 mg and above are considered therapeutic and should be taken under medical supervision. This product is for adults who have discussed its use with a health care provider.
