Source Naturals Niacinamide Vitamin B-3 100mg – 250 Tablets (Pack of 3)

Key Health Benefits of Niacinamide

Niacinamide, a form of vitamin B-3, contributes to normal energy-yielding metabolism, helping your body convert food into usable energy. It also supports the normal functioning of the nervous system and helps maintain healthy skin. As part of a balanced diet, adequate intake of niacinamide may reduce tiredness and fatigue.*

Unlike nicotinic acid, niacinamide does not cause the characteristic niacin flush, making it a comfortable choice for daily supplementation.

What Is Niacinamide (Vitamin B-3)?

Niacinamide, also known as nicotinamide, is a water-soluble B vitamin that plays a vital role in energy metabolism. It is essential for the function of over 50 metabolic reactions, most of which involve enzymes that support cellular energy production. Its bioactive forms — NAD+, NADH, NADP, and NADPH — act as catalysts in the mitochondria, helping your cells generate the energy they need to thrive.

Niacinamide is the amide form of niacin, distinct from nicotinic acid, and is preferred by those who want the benefits of vitamin B-3 without the uncomfortable skin redness and warmth associated with the flush.

Niacin vs Niacinamide: What's the Difference?

Vitamin B-3 comes in two primary supplementary forms: nicotinic acid and niacinamide. Nicotinic acid is known for causing a temporary flush reaction — redness, tingling, and warmth — due to vasodilation. Niacinamide, on the other hand, does not provoke this flush, making it more tolerable for many individuals.

Both forms support energy metabolism and cellular health, but niacinamide is often preferred for daily supplementation at higher doses because of its gentler profile. Some users may choose nicotinic acid specifically for its effects on lipid metabolism, but niacinamide offers the same foundational B-3 benefits with greater comfort.

How to Choose a High-Quality Niacinamide Supplement

When selecting a vitamin B-3 supplement, consider the form (niacinamide vs nicotinic acid), dosage, and purity. Source Naturals Niacinamide tablets are made with high-quality ingredients and are free from common allergens such as gluten, dairy, soya, and artificial colours. They are suitable for vegetarians and vegans.

Look for supplements that undergo third-party testing for potency and purity. This ensures you receive the amount of niacinamide stated on the label without contaminants. A trusted brand like Source Naturals follows Good Manufacturing Practises (GMP) to deliver consistent quality.

Recommended Dosage and How to Take

Each tablet contains 100 mg of niacinamide. The suggested use is one tablet daily, or as recommended by your health care professional. This dosage provides a substantial amount of vitamin B-3 while remaining well within safe upper intake levels for most adults.

For best absorption, take with food and a full glass of water. If you are new to niacinamide, you may start with a lower dose and gradually increase. Always follow the label instructions and consult your health care provider before exceeding the recommended serving, especially if you are pregnant, nursing, or taking medication.

Safety and Potential Side Effects

Niacinamide is generally well-tolerated at recommended doses. The most common side effects are mild and may include gastrointestinal upset or headache. Unlike nicotinic acid, niacinamide does not cause flushing at standard doses.

High doses of niacinamide (above 500 mg daily) have been associated with potential liver enzyme changes and other effects. Do not exceed the recommended dosage unless under medical supervision. Keep out of reach of children. If you experience any unusual symptoms, discontinue use and consult a health care professional.
