This water-soluble vitamin is essential for the body, as it participates in more than 50 metabolic reactions, most of them enzymatic. Unlike niacin (nicotinic acid), niacinamide does not produce the characteristic skin flushing, making it an ideal option for those seeking the benefits of vitamin B3 without discomfort.\u003c\/p\u003e\u003cp\u003eSource Naturals offers this supplement in a dosage of 100 mg per tablet, with 250 tablets per container, manufactured in the USA under strict Good Manufacturing Practices (cGMP) standards.\u003c\/p\u003e\u003ch2\u003eEFSA-backed benefits\u003c\/h2\u003e\u003cp\u003eThe European Food Safety Authority (EFSA) has approved several health claims for niacin (including niacinamide).

Niacin (nicotinic acid) can cause a temporary redness known as \"flush\" due to vasodilation. This effect is harmless but annoying for many people. Niacinamide, on the other hand, does not cause this redness, making it more suitable for daily use without discomfort.\u003c\/p\u003e\u003cp\u003eFrom a functional point of view, both forms participate in the same metabolic reactions and provide the same EFSA-backed benefits. The choice between one or the other depends on personal tolerance and specific needs. If you want to avoid the flush, niacinamide is your best option.\u003c\/p\u003e\u003ch2\u003eHow much niacinamide should I take per day?\u003c\/h2\u003e\u003cp\u003eThe recommended dose in this product is 1 tablet per day, which provides 100 mg of niacinamide. This amount is within the safe and effective range for most adults. The reference intake for vitamin B3 in the EU is 16 mg per day, so this supplement provides a significantly higher amount, suitable for covering specific needs.\u003c\/p\u003e\u003cp\u003eIt is recommended not to exceed the daily dose without prior consultation with a healthcare professional. Very high doses (above 500 mg\/day) can have adverse effects, although niacinamide is generally well tolerated.\u003c\/p\u003e\u003ch2\u003eWho should consider this supplement?\u003c\/h2\u003e\u003cp\u003eThis niacinamide supplement is suitable for people who:\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003eSeek to support their energy metabolism and reduce tiredness.\u003c\/li\u003e\n\n\u003cli\u003eWish to maintain the health of their nervous system and psychological function.\u003c\/li\u003e\n\n\u003cli\u003eWant to care for their skin and mucous membranes.\u003c\/li\u003e\n\n\u003cli\u003eFollow restrictive diets or have increased nutritional needs.\u003c\/li\u003e\n\n\u003cli\u003ePrefer to avoid the flushing associated with niacin.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003cp\u003eAs with any supplement, it is important to consult a healthcare professional before starting to take it, especially if you are pregnant, breastfeeding, or undergoing medical treatment.\u003c\/p\u003e\u003ch2\u003ePossible side effects and precautions\u003c\/h2\u003e\u003cp\u003eNiacinamide is safe and well-tolerated at recommended doses. However, at very high doses (e.g., more than 500 mg per day), it can cause mild digestive discomfort, headache, or dizziness. The flushing effect does not occur with niacinamide, unlike niacin.\u003c\/p\u003e\u003cp\u003eThe recommended daily dose should not be exceeded without medical supervision. This product is a food supplement, not a medicine, and should not be used as a substitute for a balanced diet and a healthy lifestyle. Keep out of reach of children.
