Dr Clark Niacin (Vitamin B3) Supplement – 25mg, 100 Gelatine Capsules

Dr Clark's Niacin supplement offers a straightforward, no-nonsense approach to vitamin B3 supplementation. Each capsule delivers 25mg of pure nicotinic acid—the form of niacin most widely studied for its cardiovascular benefits. Free from unnecessary additives and common allergens, this product is ideal for those seeking a clean, effective daily supplement.

What Is Vitamin B3 (Niacin)?

Vitamin B3, more commonly referred to as niacin, is an essential water-soluble vitamin that plays a fundamental role in converting the food we eat into usable energy. It is involved in over 400 enzymatic reactions, including those important for cellular metabolism, DNA repair, and cell signalling. In supplements, niacin is typically found as nicotinic acid (the form in this product) or niacinamide. Each form has its own unique properties; nicotinic acid is particularly noted for its effects on circulation and blood lipid levels.

Health Benefits of Niacin Supplementation

Niacin contributes to normal energy-yielding metabolism, meaning it helps your body extract energy from carbohydrates, fats, and proteins. It also supports the normal functioning of the nervous system and contributes to the maintenance of healthy skin and mucous membranes. Additionally, niacin plays a role in the maintenance of normal blood cholesterol levels. These benefits are recognised by the European Food Safety Authority (EFSA) and are authorised for use in the UK. This product is a food supplement and should not be used as a substitute for a varied diet and healthy lifestyle.

Niacin vs Niacinamide – Which Form Should You Choose?

This supplement contains niacin in its nicotinic acid form, which is particularly associated with supporting healthy circulation and cholesterol levels. Unlike niacinamide, nicotinic acid can cause a temporary flushing sensation—a warm, tingling redness of the skin that is harmless and typically diminishes with continued use. If you are sensitive to this effect, niacinamide might be a better option. However, for those seeking the classic cardiovascular benefits of niacin, nicotinic acid is the preferred choice.

Recommended Dosage and How to Take

Each capsule provides a moderate 25mg dose of niacin, suitable for daily maintenance. To reduce the likelihood of flushing, it is advisable to start with a low dose and gradually increase as your body adapts. Take one capsule daily with a meal and a full glass of water. Do not exceed the recommended dose unless supervised by a health care professional. Higher doses (above 50mg) may require medical oversight due to potential side effects such as flushing, itching, or gastrointestinal discomfort.

Potential Side Effects and Safety Considerations

The most common side effect of nicotinic acid is flushing, which usually lessens over time as your body becomes accustomed to the vitamin. Taking the supplement with food can help minimise this effect. In rare instances, very high doses may lead to liver toxicity, so it is important to adhere to the recommended dosage. If you have liver disease, gout, or stomach ulcers, consult your doctor before starting supplementation. This product is free from common allergens including soy, nuts, and milk, and contains no magnesium stearate, silica, or sulphates.
