Selecting a top-quality niacin supplement is key to getting the most from your health routine. Source Naturals Niacin is made in the USA under strict cGMP guidelines – it’s Non-GM, vegetarian-friendly, and backed by over 40 years of industry trust.

What Is Vitamin B3 (Niacin)?

Vitamin B3, often called niacin, is a water-soluble vitamin that’s essential for turning the food you eat into energy. It helps your body break down carbohydrates, fats, and proteins, and supports your nervous system, digestive system, and skin health. Source Naturals Niacin delivers 100 mg of pure nicotinic acid – the classic form of vitamin B3 that fuels these processes.

Health Benefits of Niacin Supplements

Niacin plays a key role in normal energy-yielding metabolism, helping to reduce tiredness and fatigue when part of a balanced diet. It also supports healthy skin and mucous membranes, and contributes to the normal function of the nervous system. Adequate niacin intake helps maintain normal psychological function. Always read the label and follow the directions for use. Supplements should not replace a balanced diet.

Recommended Dosage and How to Take Niacin

The suggested dose is one tablet daily, providing 100 mg of niacin. To minimize flushing, start with a low dose and take it with food – avoid hot drinks as they can make the sensation stronger. Stick to the recommended dose unless advised otherwise by your doctor or health professional. Always read the label and follow the directions for use.

Potential Side Effects and Safety Considerations

Niacin (nicotinic acid) can cause a harmless flushing feeling – warmth, tingling, and redness, especially on the face and chest. This is a normal reaction caused by prostaglandin release and usually fades with regular use. Taking an aspirin 30 minutes beforehand may help, but check with your doctor first. High doses (above 500 mg) may lead to liver issues, blood sugar changes, or stomach problems – this product is only 100 mg, but if you have liver disease, diabetes, or take medication, talk to your health professional before starting. Keep out of reach of children and store in a cool, dry place.

Niacin vs. Niacinamide – Which Form Is Right for You?

Niacin supplements come in different types. The most common are nicotinic acid (niacin) and niacinamide. Nicotinic acid can cause the harmless flushing sensation described above, while niacinamide doesn’t cause flushing but works a bit differently. Source Naturals Niacin uses nicotinic acid – the traditional choice for those wanting the classic niacin benefits. There’s also inositol hexanicotinate, a “no-flush” form that releases niacin more slowly. Your choice depends on your preference and how your body responds.

Frequently Asked Questions

What is niacin flushing?

Niacin flushing is a temporary feeling of warmth, itching, or redness on the skin, especially on the face and chest. It’s a normal reaction to nicotinic acid and usually lasts 15–30 minutes. Taking niacin with a low-fat snack or meal can help reduce it.

Can I take niacin on an empty stomach?

It’s best to take niacin with food to minimize stomach upset and reduce flushing. Avoid taking it with hot drinks, which can worsen the sensation.

How long does it take to see benefits?

You may notice improvements in energy and skin health within a few days to weeks – results vary. Consistent daily use is important for the best outcome.

Is 100 mg of niacin too much?

100 mg is above the recommended dietary intake (14–16 mg for adults), but it’s a common amount used for metabolic support. It’s generally safe, but if you’re unsure, check with your health professional.
