Description
Additional Information

What Makes Niacinamide Different from Nicotinic Acid?

If you've ever taken regular niacin, you might have experienced the infamous "niacin flush"—a harmless but uncomfortable tingling and redness. Niacinamide, also known as nicotinamide, avoids this reaction entirely. While both forms of vitamin B3 support energy metabolism, niacinamide offers a gentler experience, making it ideal for those who want the benefits of B3 without the flush. Source Naturals Niacinamide B-3 provides 100 mg of pure niacinamide per tablet, so you can support your body's processes comfortably.

Health Benefits of Niacinamide Supplement

Niacinamide contributes to normal energy-yielding metabolism, helping your body convert food into usable energy. It also helps maintain healthy skin and supports the normal function of the nervous system. As a precursor to NAD+, niacinamide plays a key role in cellular repair and healthy aging. *

* This product is a Natural Health Product. Always read and follow the label. Consult your healthcare practitioner before use, especially if you are pregnant, breastfeeding, or taking any medications.

Recommended Dosage and How to Take Niacinamide

Adults should take one 100 mg tablet daily, preferably with a meal to enhance absorption and minimize possible stomach discomfort. This moderate dose is suitable for daily maintenance. Store in a cool, dry place. Do not exceed the recommended serving unless directed by your healthcare practitioner.

Safety and Side Effects

Niacinamide is generally well-tolerated. Because it does not cause flushing, it is often preferred for long-term use. Some individuals may experience mild nausea or stomach upset, which can be reduced by taking it with food. High doses (above 500 mg daily) should only be used under medical supervision, as excessive intake may affect liver function. Do not use this product as a substitute for a balanced diet or medical treatment. Keep out of reach of children.

Why Choose Source Naturals Niacinamide B-3?

What Is Niacinamide (Vitamin B3)?

Niacinamide, also called nicotinamide, is one of two primary forms of vitamin B3. This water-soluble nutrient is essential for over 50 metabolic reactions, particularly those involved in energy production, DNA repair, and cellular signaling. Unlike nicotinic acid, niacinamide does not cause the characteristic niacin flush. Source Naturals Niacinamide B-3 delivers 100 mg of pure niacinamide per tablet, providing a comfortable way to support your body's fundamental processes.

Frequently Asked Questions

Is niacinamide the same as niacin?

Niacinamide and niacin are both forms of vitamin B3, but they have slightly different chemical structures and effects. Niacinamide does not cause flushing.

Can I take niacinamide on an empty stomach?

While niacinamide is generally gentle, taking it with food may help reduce the risk of stomach discomfort.

How long does it take to see benefits?

Consistent daily use supports ongoing metabolic health. Individual benefits may vary based on diet and lifestyle.

Can I take more than one tablet?

We recommend following the suggested use of one tablet daily. Do not exceed unless directed by a healthcare professional.
