NOW Foods Niacin (Vitamin B-3) 500 mg, Flush-Free, Double Strength, 90 Veg Capsules

What Is Inositol Hexanicotinate?

Niacin, or vitamin B-3, is an essential water-soluble vitamin that helps convert food into energy and supports the nervous system. However, many people avoid regular niacin because of the harmless but unpleasant 'niacin flush' – a warm, tingling feeling. NOW Foods Flush-Free Niacin 500 mg uses inositol hexanicotinate, a form where six niacin molecules bind to inositol, allowing a gradual release that minimises flushing. Each double-strength capsule delivers 500 mg of niacin without the discomfort, making it easier to get your daily B-3.

Dosage Recommendations and Tips

Each capsule provides 500 mg of flush-free niacin – a double-strength dose. For most adults, taking one capsule daily with food is sufficient. Since niacin is water-soluble, excess is excreted in urine, but high doses (above 50 mg) require caution. If you’re new to niacin, start with a lower dose and increase gradually. Do not exceed the recommended serving without consulting your healthcare professional. This product is vegan, non-GM, Gluten Free, and GMP certified.

Comparing Flush and Flush-Free

Standard niacin (nicotinic acid) triggers a temporary flush as blood vessels dilate – it’s harmless but can be alarming. Flush-free niacin (inositol hexanicotinate) is absorbed more slowly, avoiding that sudden release. This makes it ideal for those sensitive to flushing. Some research suggests inositol hexanicotinate may affect cholesterol differently, so if you’re taking niacin for specific health reasons, talk to your doctor about which form suits you.

Supporting Your Health with Niacin

Niacin plays a key role in energy metabolism, DNA repair, and cellular signalling. It supports normal nervous system function, healthy skin, and contributes to psychological wellbeing as part of a balanced diet. The flush-free form offers the same nutritional support without the typical side effects. Niacin also helps maintain normal mucous membranes and reduces tiredness and fatigue. As with all B vitamins, it works best alongside other B-complex nutrients.

Safety and Precautions

Although flush-free niacin greatly reduces the chance of flushing, mild gastrointestinal discomfort or headache may still occur. Inositol hexanicotinate is generally well-tolerated, but high intakes of niacin (especially as nicotinic acid) have been linked to liver toxicity and elevated blood sugar. Pregnant or nursing women's, and those with liver disease, peptic ulcers, gout, or diabetes should consult a doctor before use. Always read the labelled and follow the directions for use.

Selecting a Trusted Supplement

When choosing a niacin supplement, look for third-party testing to insure purity and potency. NOW Foods follows strict GMP certification, with in-house ISO/IEC accredited labs testing stability and formulation. This flush-free formula is vegan, non-GM, and Gluten Free – important for many health-conscious Australians. The double-strength 500 mg dose means fewer capsules. Since 1968, NOW Foods has been a family- and employee-owned manufacturer committed to quality and transparency.
