It is part of the B vitamin complex and acts as a precursor to key coenzymes such as NAD and NADP, which are involved in over 400 enzymatic reactions. These coenzymes are fundamental for converting food into usable energy for cells, which explains their role in energy metabolism. Additionally, niacin is necessary for the maintenance of skin, mucous membranes, and the nervous system.\u003c\/p\u003e\u003cp\u003eAlthough it can be obtained through a balanced diet including meats, fish, legumes, and whole grains, many people turn to supplements to ensure adequate intake, especially those with restrictive diets or increased needs.\u003c\/p\u003e\u003ch2\u003eBenefits backed by EFSA\u003c\/h2\u003e\u003cp\u003eThe European Food Safety Authority (EFSA) has approved several health claims for niacin, provided the dose is sufficient. This 100 mg per tablet supplement contributes to:\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003eNormal energy-yielding metabolism.\u003c\/li\u003e\n\n\u003cli\u003eNormal functioning of the nervous system.\u003c\/li\u003e\n\n\u003cli\u003eNormal psychological function.\u003c\/li\u003e\n\n\u003cli\u003eThe maintenance of normal skin and mucous membranes.\u003c\/li\u003e\n\n\u003cli\u003eThe reduction of tiredness and fatigue.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003cp\u003eThese benefits are backed by a broad scientific consensus and are not isolated claims. It is important to note that niacin cannot replace a varied diet or a healthy lifestyle, but it can be a valuable complement.\u003c\/p\u003e\u003ch2\u003eNiacin vs Niacinamide: key differences\u003c\/h2\u003e\u003cp\u003eVitamin B3 comes in two main forms: niacin (nicotinic acid) and niacinamide (nicotinamide). The main difference lies in the flush effect or skin redness caused by niacin at moderate to high doses. This effect is temporary and generally harmless, caused by peripheral vasodilation. Niacinamide, on the other hand, does not produce a flush and is often used in skin formulations or for those looking to avoid this reaction.\u003c\/p\u003e\u003cp\u003eThis product contains niacin in its nicotinic acid form, which is the one that offers the characteristic flush effect. Many users prefer it because they associate that warmth and redness with an active metabolic response. If you are sensitive to the flush, you can start with lower doses or take it with food to minimize the intensity. However, it is a normal reaction and should not be a cause for alarm.\u003c\/p\u003e\u003ch2\u003eRecommended dosage and how to take it\u003c\/h2\u003e\u003cp\u003eEach tablet provides 100 mg of niacin, a moderate dose that is below the tolerable upper intake level established by EFSA (500 mg\/day for immediate-release niacin). The recommended daily dose for adults is one tablet per day, preferably with a meal to improve tolerance.\u003c\/p\u003e\u003cp\u003eThe indicated dose should not be exceeded without consulting a healthcare professional. The 110-tablet container provides approximately three and a half months of supply if one unit is taken daily. Remember that food supplements should not be used as a substitute for a balanced diet.\u003c\/p\u003e\u003ch2\u003ePossible side effects: the flush\u003c\/h2\u003e\u003cp\u003eThe most well-known effect of niacin is the flush, a sensation of warmth, itching, or redness in the face, neck, and chest. It occurs between 15 and 30 minutes after ingestion and usually lasts between 15 and 60 minutes. It is a normal and harmless vasodilatory reaction. To reduce its occurrence, it is recommended to take niacin with food or to gradually increase the dose (although this product already comes in fixed doses).\u003c\/p\u003e\u003cp\u003eOther less common possible side effects include mild gastrointestinal discomfort or headache. If you experience symptoms such as severe hives, difficulty breathing, or swelling, discontinue use and consult a doctor. This product is gluten-free, contains no genetically modified organisms, and is suitable for vegans, minimizing risks for people with allergies or dietary restrictions.\u003c\/p\u003e\u003ch2\u003eWho should consider this supplement?\u003c\/h2\u003e\u003cp\u003eThis niacin supplement is suitable for anyone who wishes to support their daily energy and nervous system function. It is especially useful for those who experience frequent fatigue, follow vegetarian or vegan diets (where animal sources of B3 are limited), or have an increased need due to stress or physical activity. It is also an option for those looking to maintain skin and mucous membrane health.\u003c\/p\u003e\u003cp\u003eSince it is suitable for vegans, gluten-free, and non-GMO, it adapts to a wide variety of lifestyles. However, if you are pregnant, breastfeeding, taking any medication, or suffer from any liver disease or peptic ulcer, consult your doctor before starting supplementation. Niacin is safe when used correctly, but a professional can guide you on the most appropriate dose for you.\u003c\/p\u003e","brand":"21st Century","offers":[{"title":"Default Title","offer_id":48761682690202,"sku":null,"price":22.12,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/4831\/0170\/files\/618OQTG5JYL._AC_SL1500.jpg?v=1784396097","url":"https:\/\/vitaminaspain.es\/es\/products\/niacina-100-mg-110-comprimidos-21st-century-b004rcxnqk","provider":"vitaminaspain","version":"1.0","type":"link"}
