It is part of the B complex and plays a key role in converting food into energy. This Nutricost supplement provides 500 mg of niacin per capsule, in its quick-release form, which produces the characteristic \"flush\" or skin reddening, a harmless but noticeable reaction.\u003c\/p\u003e\u003cp\u003eNiacin is a precursor to the coenzymes NAD and NADP, which are fundamental in over 400 enzymatic reactions related to cellular metabolism. Therefore, an adequate intake of this vitamin contributes to normal energy metabolism, the functioning of the nervous system, and the reduction of tiredness and fatigue, according to EFSA-approved claims.\u003c\/p\u003e\u003ch2\u003eEFSA-backed benefits\u003c\/h2\u003e\u003cp\u003eThe European Food Safety Authority (EFSA) has evaluated and authorized several health claims for niacin.

However, \u003cstrong\u003ethis product should not be used as a substitute for a balanced diet\u003c\/strong\u003e, and it is important to consult a healthcare professional before starting any supplementation, especially at high doses.\u003c\/p\u003e\u003ch2\u003eForms of Niacin: Flush Niacin vs. Niacinamide\u003c\/h2\u003e\u003cp\u003eThere are two main forms of vitamin B3 in supplements: nicotinic acid (niacin) and nicotinamide (niacinamide). The key difference is the \"flush\" or reddening caused by niacin. This effect is due to the release of prostaglandins and usually lasts between 15 and 30 minutes. Although it can be uncomfortable, it is harmless and tends to decrease with continued use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNiacinamide\u003c\/strong\u003e, on the other hand, does not cause flushing and is often used in skin health formulations and flush-free supplements. Some products combine both forms or use inositol hexanicotinate, a sustained-release form that minimizes the flush.\u003c\/p\u003e\u003cp\u003eIn this case, Nutricost offers pure niacin in its nicotinic acid form, ideal for those seeking the complete metabolic effects of vitamin B3. If you prefer to avoid the flush, you can opt for niacinamide, but keep in mind that the effects on lipid metabolism may differ.\u003c\/p\u003e\u003ch2\u003eRecommended dosage and use\u003c\/h2\u003e\u003cp\u003eEach capsule contains 500 mg of niacin. The recommended daily dose for adults varies according to individual needs, but generally ranges from 15 to 20 mg per day to maintain adequate levels. However, in therapeutic contexts or under medical supervision, much higher doses, such as those offered by this product, are used.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e Do not exceed the recommended dose without consulting a healthcare professional. High doses of niacin (above 500 mg\/day) can cause side effects such as flushing, itching, gastrointestinal discomfort, or, in rare cases, liver toxicity. It is recommended to start with a lower dose (e.g., 100 mg) and gradually increase to assess tolerance. Taking the supplement with food may reduce the intensity of the flush.\u003c\/p\u003e\u003ch2\u003ePossible side effects and warnings\u003c\/h2\u003e\u003cp\u003eThe most common effect of niacin is the \u003cstrong\u003eflush\u003c\/strong\u003e or skin reddening, accompanied by a sensation of warmth and itching. This effect is transient and disappears on its own. To minimize it, the supplement can be taken after meals or with aspirin (under medical advice).\u003c\/p\u003e\u003cp\u003eOther possible side effects include: stomach upset, nausea, headache, and dizziness. At very high doses (\u0026gt; 2 g\/day) and for prolonged periods, it has been associated with elevated liver enzymes and liver toxicity. Therefore, its use is not recommended in people with liver disease, peptic ulcer, or arterial hypotension without medical supervision.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWarning:\u003c\/strong\u003e This product contains high doses of niacin and may cause intense flushing.

It occurs 15 to 30 minutes after taking niacin and disappears in approximately one hour. It is caused by the release of prostaglandins and is harmless, though it can be uncomfortable.\u003c\/p\u003e\u003ch3\u003eHow much niacin should I take daily?\u003c\/h3\u003e\u003cp\u003eThe recommended daily allowance (RDA) for adults is 15-20 mg.
