Description
Additional Information

Recommended Dosage and How to Take Niacin

For adults, take one tablet daily with a meal. The sustained release formulation allows for a gradual release of niacin, which can further reduce the likelihood of flushing. Start with a lower dose if you are new to niacin and gradually increase as tolerated. Always consult a healthcare professional before taking high-dose niacin.

Health Benefits of Niacin Supplements

Niacin contributes to normal energy-yielding metabolism and helps maintain healthy skin and mucous membranes. It also supports psychological function and reduces tiredness and fatigue. Research indicates that niacin may help maintain healthy cholesterol levels when used as part of a balanced diet. These statements have not been evaluated by Health Canada. This product is not intended to diagnose, treat, , or prevent any disease.

Niacin vs. Niacinamide – Which Form Is Right for You?

Niacin comes in two common forms: nicotinic acid (niacin) and niacinamide. Nicotinic acid is known for its potential to cause a temporary flushing sensation, while niacinamide does not cause flushing. NOW Foods Niacin is in the nicotinic acid form, but the sustained release design helps minimize flushing. If you prefer a non-flush option, consider a niacinamide supplement.

Frequently Asked Questions

What is the difference between immediate release and sustained release niacin?

Immediate release niacin enters the bloodstream quickly, often causing a more intense flushing reaction. Sustained release niacin releases gradually, which can minimize flushing and provide a more consistent level of the vitamin in your system.

Can I take niacin on an empty stomach?

It is best to take niacin with a meal to reduce the risk of stomach upset and minimize flushing. Food can also help slow absorption.

How long does the flushing last?

The flushing sensation typically lasts 15 to 30 minutes, though it can vary. It usually decreases with consistent use. Avoid taking niacin with hot beverages or alcohol, as these can worsen flushing.

Potential Side Effects and Safety Considerations

Niacin may cause temporary flushing, itching, or tingling, especially when starting supplementation. This reaction is harmless and often diminishes with continued use. Taking niacin with food and not skipping doses can help manage these symptoms. Avoid taking this product if you have liver disease, active peptic ulcer, or low blood pressure. Consult your doctor if you are pregnant, nursing, or taking any medications. Always read the label and follow directions for use.

How to Choose a High-Quality Niacin Supplement

Look for supplements from reputable brands that undergo third-party testing, such as NOW Foods. Check for certifications like Non-GMO, vegan, and gluten-free. The sustained release form ensures a steady absorption and reduced side effects. NOW Foods has been family-owned since 1968 and packages their products in the USA.

What Is Vitamin B3 (Niacin)?

Niacin, also known as vitamin B3, is a water-soluble vitamin that plays a vital role in energy metabolism, DNA repair, and cellular signaling. As an essential nutrient, your body cannot produce it—you must obtain it through diet or supplementation. NOW Foods Niacin 500 mg Sustained Release offers a convenient way to support your daily nutritional needs.
