Swanson Niacin (Vitamin B3) 500 mg, 250 Capsules

What Is Vitamin B3 (Niacin)?

Niacin, also known as vitamin B3, is a water-soluble B vitamin essential for turning food into energy. It plays a key role in carbohydrate metabolism, helping your body break down nutrients for fuel. Additionally, niacin supports healthy blood lipid levels, making it a popular supplement for heart health. Swanson Niacin delivers 500 mg of high-quality niacin per capsule, derived from plant-based ingredients.

Niacin vs Niacinamide – Which Form Is Right for You?

Niacin supplements come in different forms. The most common is nicotinic acid, the type used in Swanson Niacin. Nicotinic acid is known for supporting lipid metabolism, but it can cause a temporary, harmless flushing sensation (warmth, redness, tingling) as blood vessels dilate. This feeling usually eases with continued use or by starting with a lower dose. Niacinamide, another form of vitamin B3, doesn't cause flushing but lacks the same lipid-supporting properties. Swanson Niacin uses nicotinic acid for those looking for comprehensive cardiovascular and metabolic support.

Health Benefits of Niacin Supplements

Niacin contributes to normal energy-yielding metabolism, helping your body efficiently produce energy from food. It also helps maintain healthy skin and mucous membranes. Many people use niacin to support healthy cholesterol levels already within the normal range. Research suggests niacin may help raise HDL ('good') cholesterol while supporting healthy triglyceride levels. Results vary, so it's important to maintain a balanced diet and active lifestyle.

Dietary supplements are not medicines. Always read the label and follow directions for use.

Recommended Dosage and How to Take Niacin

Each capsule contains 500 mg of niacin (as nicotinic acid). Take one capsule daily with food and water. To minimize the risk of flushing, start with a lower dose (e.g., 100–250 mg) and increase gradually over several weeks. Don't exceed the recommended serving unless a healthcare professional tells you to. High-dose niacin (above 50 mg) should only be taken under medical supervision, especially if you're on cholesterol-lowering medications or have liver concerns.

Potential Side Effects and Safety Considerations

Niacin is generally well tolerated, but high doses can cause side effects. The most common is the 'niacin flush' – a harmless but sometimes uncomfortable sensation of warmth, itching, or redness. Taking niacin with food or using an extended-release formula can reduce this effect. Other possible side effects include stomach upset, headache, or dizziness. If you experience severe or ongoing reactions, stop use and see your doctor. Niacin may interact with some medications, so always talk to a healthcare provider before starting supplements, especially if you have a medical condition or are pregnant or breastfeeding.

How to Choose a High-Quality Niacin Supplement

Quality matters when choosing a niacin supplement. Swanson Niacin is made in GMP-certified facilities and undergoes independent third-party testing for purity and strength. The formula is plant-based and free from unnecessary processing. Since 1969, Swanson Health has been committed to providing science-backed supplements you can trust. Look for products that clearly state the niacin form (nicotinic acid vs niacinamide) and amount per serve. Third-party certifications like Non-GM or vegan-friendly add confidence in the product's integrity.
