Source Naturals Niacin 100 mg – Vitamin B3 Supplement – 100 Tablets

Niacin, also known as vitamin B3, is a water-soluble vitamin essential for turning food into energy. Your body can't make it on its own, so you need to get it from your diet or supplements. Source Naturals Niacin provides 100 mg of vitamin B3 in easy-to-swallow tablets, made from non-GMO ingredients and manufactured in the USA under strict quality controls. Always read the label and follow directions for use.

Key Health Benefits of Niacin

Niacin helps your body convert food into energy, supports normal skin and nervous system function, and plays a role in hormone production. It's also known to help maintain healthy cholesterol levels already within the normal range. These benefits are backed by research on the essential role of vitamin B3 in human health.

What's the Difference Between Niacin and Niacinamide?

This product contains nicotinic acid, which can cause a harmless 'niacin flush' – a warm, red, tingling sensation on the skin. This usually passes within 15 to 60 minutes and often lessens with regular use. Niacinamide, another form of B3, doesn't cause flushing but also doesn't affect lipid metabolism the same way. Inositol hexanicotinate is another no-flush option, though absorption varies. If you're new to niacin, starting with 100 mg can help you adjust.

How to Take Niacin

Take one 100 mg tablet daily, preferably with food, to reduce stomach discomfort. To minimise flushing, have it after a meal with a full glass of water – avoid hot drinks as they can make the flush worse. If you're just starting, consider breaking the tablet in half for a 50 mg dose. Never exceed the recommended dose without checking with your health care professional, especially if you're on medication or have underlying health issues.

Safety and Possible Side Effects

Niacin is generally safe, but high doses can cause itching, digestive upset, or liver problems. The 100 mg dose here is safe for most adults. However, if you have liver disease, ulcers, or gout, avoid high-dose niacin unless your doctor says it's okay. Always consult a professional before starting any new supplement, especially if you're pregnant, nursing, or taking prescription drugs.
