Recommended Dosage

Each tablet contains 100 mg of niacinamide. The suggested serving is one tablet daily, or as recommended by your healthcare practitioner. This amount provides a substantial level of vitamin B-3 while remaining within safe upper intake limits for most adults.

For optimal absorption, consume with a meal 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 healthcare practitioner before exceeding the recommended serving, especially if you are pregnant, nursing, or taking medication.

What Is Niacinamide (Vitamin B-3)?

Niacinamide, also referred to as nicotinamide, is a form of vitamin B-3 that plays a vital role in energy metabolism. This water-soluble vitamin helps your body convert food into usable energy. It is essential for over 50 metabolic reactions, most involving enzymes that support cellular energy production. Its bioactive forms — NAD+, NADH, NADP, and NADPH — act as catalysts in the mitochondria, enabling your cells to generate the energy they need.

Unlike nicotinic acid (another form of niacin), niacinamide does not cause the characteristic niacin flush, making it a preferred choice for those who want the benefits of vitamin B-3 without the uncomfortable skin redness and warmth.

Key Health Benefits of Niacinamide

Niacinamide contributes to normal energy-yielding metabolism, helping your body break down proteins, fatty acids, and carbohydrates. It also supports the synthesis of fatty acids and the formation of steroid hormones and red blood cells. Additionally, it aids in the maintenance of normal skin health and nervous system function.

As a cofactor in numerous enzymatic reactions, niacinamide helps maintain healthy cells and tissues. Adequate vitamin B-3 intake helps maintain healthy cholesterol levels already within the normal range and promotes cardiovascular wellness.*

Niacin vs. Niacinamide – Understanding 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. While some users may choose nicotinic acid specifically for its effects on lipid metabolism, 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, soy, 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.

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 healthcare practitioner.
