It is part of the B complex and plays a crucial role in converting food into energy. Niacin is naturally found in foods such as lean meats, fish, legumes, and whole grains, but sometimes a supplement may be necessary to meet daily needs.\u003c\/p\u003e\u003cp\u003eThis Swanson supplement offers 500 mg of niacin per capsule in its nicotinic acid form, ideal for those seeking an extra boost of this vitamin.\u003c\/p\u003e\u003ch2\u003eBenefits endorsed by the EFSA\u003c\/h2\u003e\u003cp\u003eThe European Food Safety Authority (EFSA) has approved several health claims for niacin. Among them, it highlights that niacin contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function, the maintenance of normal skin and mucous membranes, and the reduction of tiredness and fatigue.\u003c\/p\u003e\u003cp\u003eFurthermore, clinical studies have suggested that niacin may help maintain healthy blood lipid levels, although this claim is not authorized by the EFSA for food supplements. Therefore, it is important to consider niacin as part of a comprehensive approach to cardiovascular health, always under professional supervision.\u003c\/p\u003e\u003ch2\u003eForms of niacin: niacin vs. niacinamide\u003c\/h2\u003e\u003cp\u003eNiacin comes in several forms. The most common is nicotinic acid, which is the form used in this supplement. This form can cause a flushing or \"flush\" effect on the skin, especially at high doses, due to vasodilation. On the other hand, niacinamide (nicotinamide) does not produce this effect, but it also does not have the same effects on blood lipids.\u003c\/p\u003e\u003cp\u003eSome people prefer niacinamide to avoid the flush, while others specifically seek nicotinic acid for its potential cardiovascular benefits. It is important to choose the appropriate form based on personal goals and always in consultation with a healthcare professional.\u003c\/p\u003e\u003ch2\u003eRecommended dosage\u003c\/h2\u003e\u003cp\u003eThe recommended daily allowance (RDA) of niacin for adults is approximately 16 mg per day for men and 14 mg for women. However, in supplementation contexts, doses can be much higher, such as the 500 mg in this product.\u003c\/p\u003e\u003cp\u003eIt is essential not to exceed the recommended dose without medical supervision, as very high doses can cause side effects. Generally, it is recommended to start with a low dose and gradually increase it to minimize flushing. Ideally, the capsule should be taken with food to reduce stomach upset.\u003c\/p\u003e\u003ch2\u003ePossible side effects\u003c\/h2\u003e\u003cp\u003eThe most well-known side effect of niacin (nicotinic acid) is skin flushing, which may be accompanied by itching or a sensation of heat. This effect is temporary and usually subsides with continued use. To minimize it, the supplement can be taken with food or opt for sustained-release forms.\u003c\/p\u003e\u003cp\u003eOther less common effects include gastrointestinal discomfort, headache, or dizziness. At very high and prolonged doses, niacin can affect the liver. Therefore, it is important not to exceed the recommended doses and to consult a doctor before starting supplementation, especially if other medications are being taken.\u003c\/p\u003e\u003ch2\u003eWho should take niacin supplements?\u003c\/h2\u003e\u003cp\u003eNiacin supplements can be beneficial for people with a deficiency of this vitamin, which is rare in developed countries but possible with very restrictive diets. They can also be useful for those seeking to support their energy metabolism, reduce fatigue, or maintain skin and nervous system health.\u003c\/p\u003e\u003cp\u003eHowever, not everyone needs a supplement. A balanced diet usually provides sufficient amounts. Before taking any supplement, it is advisable to consult a healthcare professional to assess individual needs.\u003c\/p\u003e","brand":"Swanson","offers":[{"title":"Default Title","offer_id":48761035260058,"sku":null,"price":35.76,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/4831\/0170\/files\/71VQe918LBL._AC_SL1168.jpg?v=1784380814","url":"https:\/\/vitaminaspain.es\/es\/products\/swanson-niacina-vitamina-b3-500-mg-250-capsulas-b00068sj40","provider":"vitaminaspain","version":"1.0","type":"link"}
