Product Overview

Niacin, also known as Vitamin B-3, is an essential nutrient that plays a critical role in energy production, DNA repair, and cellular health. NOW Foods Niacin 500 mg Sustained Release tablets are designed to provide a controlled release of this vital vitamin throughout the day, ensuring optimal absorption and minimizing the common 'niacin flush' associated with immediate-release forms. Each bottle contains 250 tablets, offering a convenient two-month supply at the recommended dosage.

Key Features and Benefits

  • Sustained Release Formula: The unique sustained release technology delivers niacin gradually, reducing the likelihood of the temporary flushing and itching sensation often experienced with standard niacin supplements.
  • High Potency: Each tablet provides 500 mg of Niacin (as Niacinamide and Niacin), supporting healthy cholesterol levels already within normal range and promoting cardiovascular wellness.
  • Energy Metabolism Support: Niacin is a key component of coenzymes NAD and NADP, which are essential for converting food into cellular energy. This makes it ideal for those with active lifestyles or increased energy demands.
  • Nutritional Health: As part of the B-complex family, niacin supports nervous system function, healthy skin, and proper digestion. It also aids in the synthesis of hormones and red blood cells.
  • Quality Assured: NOW Foods is a trusted brand known for rigorous quality testing. This product is non-GMO, vegan/vegetarian, and free from common allergens like gluten, soy, and dairy.

How to Use

Take one (1) tablet daily with a meal. Swallow whole — do not crush or chew, as this may interfere with the sustained release mechanism. For best results, use consistently as part of a balanced diet and healthy lifestyle. Consult your healthcare practitioner before use if you are pregnant, nursing, taking medication, or have a medical condition.

Who It Is For

This supplement is ideal for adults seeking to support their cardiovascular health, energy levels, and overall nutritional well-being. It is particularly beneficial for individuals who follow a vegetarian or vegan diet, as niacin from food sources may be limited. The sustained release formula is perfect for those who are sensitive to the niacin flush but still want the benefits of high-dose niacin.

Why Choose This Product

NOW Foods Niacin 500 mg Sustained Release stands out for its quality, potency, and value. With 250 tablets per bottle, you get a long-lasting supply at an affordable price. The sustained release technology ensures maximum comfort and efficacy, making it a preferred choice for daily supplementation. Backed by decades of manufacturing excellence, NOW Foods guarantees purity and potency through third-party testing. Choose this product for reliable support of your nutritional health.
