NOW Foods Niacinamida 500mg Vitamina B-3, 100 Cápsulas (Paquete de 3)

What is Niacinamide (Vitamin B3)?

NOW Foods Niacinamide 500Mg — Niacinamide, also known as nicotinamide, is a form of vitamin B3 (niacin). Unlike common niacin, niacinamide does not cause the characteristic redness or "flush" that many people experience when taking high doses of niacin. This water-soluble vitamin plays an essential role in cellular energy metabolism, helping convert food into usable energy for the body. Additionally, it is a precursor to key coenzymes such as NAD+, NADH, NADP, and NADPH, which are involved in hundreds of biochemical reactions, including DNA repair and cell signaling.

Each capsule of this supplement provides 500 mg of pure niacinamide, in a vegan, non-GMO, and Kosher certified format. NOW Foods is a family-owned American company with over 50 years of experience manufacturing high-quality supplements, ensuring GMP processes and stability and potency analyses.

Benefits backed by the EFSA

The European Food Safety Authority (EFSA) has approved several health claims for niacin (and by extension, niacinamide). These include:

• Niacin contributes to normal energy-yielding metabolism.
• Niacin contributes to the normal functioning of the nervous system.
• Niacin contributes to normal psychological function.
• Niacin contributes to the maintenance of normal skin and mucous membranes.
• Niacin contributes to the reduction of tiredness and fatigue.

These benefits are backed by decades of scientific research. By taking niacinamide regularly, you can support your daily energy, skin health, and mental well-being, always within a balanced diet and a healthy lifestyle.

Niacin vs. Niacinamide: which to choose?

The main difference between niacin (nicotinic acid) and niacinamide is their effect on vasodilation. Niacin produces temporary redness due to the release of prostaglandins, while niacinamide does not. For this reason, niacinamide is the preferred form for those who wish to avoid that sensation of heat and flushing.

Both forms are converted into the same active coenzymes (NAD+, NADH, etc.), so their metabolic benefits are equivalent. However, niacinamide is more commonly used in formulations for skin health, cognitive support, and energy without discomfort. Furthermore, some studies suggest that niacinamide may have additional antioxidant and cell-protective properties.

In this NOW Foods supplement, niacinamide has been chosen, offering a gentle and effective experience for daily vitamin B3 supplementation.

Recommended dosage and how to take

The recommended daily dose for adults is one 500 mg capsule daily, preferably with a meal to facilitate absorption. Do not exceed this dose without consulting a healthcare professional, as very high doses of niacinamide (above 2-3 grams per day) can cause side effects such as liver discomfort.

This pack contains 3 bottles of 100 capsules each, providing a supply for approximately 300 days. It is important to store the product in a cool, dry place, out of reach of children.

Possible side effects and precautions

Niacinamide is generally well tolerated. Unlike niacin, it does not produce flushing, but in very high doses, it can cause nausea, headache, or elevated liver enzymes. Therefore, it is essential to respect the indicated dose.

People with liver disease, gastric ulcers, or diabetes should consult their doctor before taking niacinamide supplements. Caution is also recommended for pregnant or breastfeeding women, although moderate doses are usually safe.

This product is a food supplement and should not be used as a substitute for a varied and balanced diet. Consult a healthcare professional before starting any supplementation.

Who should consider niacinamide supplementation?

Niacinamide can be beneficial for people with restrictive diets (vegans, vegetarians), those experiencing frequent fatigue, athletes seeking to optimize energy metabolism, or those wishing to maintain skin and nervous system health. It is also useful for those taking medications that interfere with the absorption of B vitamins.

If you are looking for a high-quality, flush-free vitamin B3 supplement with certifications that guarantee its purity, NOW Foods niacinamide is an excellent choice. Its capsule format facilitates dosage, and its triple pack offers excellent value for money.
