NOW Foods Niacin (Vitamin B-3), 500 mg, 100 Capsules

Description
Additional Information

Selecting a Quality Niacin Supplement

When choosing a niacin supplement, look for products tested for purity and potency. NOW Foods Niacin is manufactured in GMP-certified facilities and is Non-GMO, vegan, and gluten-free. The 500 mg dose offers a potent immediate-release option. Always opt for a trusted brand with transparent labelling.

What Is Vitamin B3 (Niacin)?

Vitamin B3, or niacin, is a water-soluble B vitamin essential for energy metabolism. It helps convert food into usable energy, supports cellular function, and maintains healthy skin and nervous system. This NOW Foods supplement delivers 500 mg of niacin (as nicotinic acid) in a convenient capsule.

Benefits of Niacin for Your Health

Niacin contributes to normal energy-yielding metabolism, aiding your body in utilising carbohydrates, fats, and proteins. It also supports normal skin and mucous membrane maintenance and nervous system function. As part of a healthy diet, niacin helps maintain healthy cholesterol levels. This product is a source of niacin. Consult a healthcare practitioner for use as a supplement. Do not use if seal is broken. Keep out of reach of children.

Niacin vs. Niacinamide: Which Form Should You Choose?

Niacin (nicotinic acid) and niacinamide are two forms of vitamin B3. Niacin often causes a temporary flushing sensation—a harmless warmth and redness that many consider a sign of efficacy. Niacinamide does not cause flushing and is typically used for skin health. NOW Foods Niacin uses nicotinic acid, ideal for those seeking the classic niacin experience and cardiovascular support.

Recommended Dosage and Usage Tips

Each capsule provides 500 mg of niacin (nicotinic acid). Since this is a high dose, start with a lower amount if you are new to niacin—for instance, half a capsule (250 mg)—and gradually increase over several weeks. Taking niacin with food can reduce the flushing effect. Always consult a healthcare professional before starting high-dose supplementation.

Potential Side Effects and Precautions

The most common side effect of niacin is flushing, which is harmless and temporary. Others may include mild stomach discomfort. Those with liver conditions, peptic ulcers, or taking blood pressure or cholesterol medications should seek medical advice before use. Flushing can be minimized by starting low, taking with food, or using extended-release forms. Avoid exceeding the recommended dose. Niacin may cause a harmless flushing of the skin.

Frequently Asked Questions

What is the difference between niacin and niacinamide?

Niacin (nicotinic acid) causes flushing and is often used for cholesterol support; niacinamide does not flush and is more common for skin and joint health. Both are vitamin B3 but have different effects.

How much niacin should I take daily?

The recommended dietary allowance (RDA) for adults is about 14-16 mg, but higher doses target specific health goals. Follow label directions and consult a healthcare practitioner for personalized advice.

Can niacin help with cholesterol?

Research suggests niacin may help maintain healthy cholesterol levels when combined with diet and lifestyle changes. It is not a substitute for medical treatment. Speak with your healthcare provider.

Does niacin cause a flush?

Yes, immediate-release niacin like this product can cause a harmless flushing sensation. This effect usually lessens with continued use and can be reduced by starting with a lower dose.
