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.\u003c\/p\u003e\u003cp\u003eEach 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.\u003c\/p\u003e\u003ch2\u003eBenefits backed by the EFSA\u003c\/h2\u003e\u003cp\u003eThe European Food Safety Authority (EFSA) has approved several health claims for niacin (and by extension, niacinamide). These include:\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003eNiacin contributes to normal energy-yielding metabolism.\u003c\/li\u003e\n\n\u003cli\u003eNiacin contributes to the normal functioning of the nervous system.\u003c\/li\u003e\n\n\u003cli\u003eNiacin contributes to normal psychological function.\u003c\/li\u003e\n\n\u003cli\u003eNiacin contributes to the maintenance of normal skin and mucous membranes.\u003c\/li\u003e\n\n\u003cli\u003eNiacin contributes to the reduction of tiredness and fatigue.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003cp\u003eThese 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.\u003c\/p\u003e\u003ch2\u003eNiacin vs. Niacinamide: which to choose?\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eBoth 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.\u003c\/p\u003e\u003cp\u003eIn this NOW Foods supplement, niacinamide has been chosen, offering a gentle and effective experience for daily vitamin B3 supplementation.\u003c\/p\u003e\u003ch2\u003eRecommended dosage and how to take\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch2\u003ePossible side effects and precautions\u003c\/h2\u003e\u003cp\u003eNiacinamide 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.\u003c\/p\u003e\u003cp\u003ePeople 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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch2\u003eWho should consider niacinamide supplementation?\u003c\/h2\u003e\u003cp\u003eNiacinamide 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.\u003c\/p\u003e\u003cp\u003eIf 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.\u003c\/p\u003e","brand":"NOW Foods","offers":[{"title":"Default Title","offer_id":48765057859738,"sku":null,"price":46.03,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/4831\/0170\/files\/51Jyxe2pH1L._AC_SL1000.jpg?v=1784494165","url":"https:\/\/vitaminaspain.es\/es\/products\/now-foods-niacinamida-500mg-vitamina-b3-100-capsulas-paquete-3-b01kyaizru","provider":"vitaminaspain","version":"1.0","type":"link"}
