Unlike niacin (nicotinic acid), niacinamide does not cause the characteristic skin redness or flush. This water-soluble vitamin actively participates in over 50 metabolic reactions, primarily enzymatic. Its bioactive forms—NAD+, NADH, NADP, and NADPH—act as cofactors in cellular energy production, protein and fatty acid metabolism, fatty acid synthesis, and the formation of steroid hormones and red blood cells. Each Source Naturals tablet provides 100 mg of high-purity niacinamide, ideal for those seeking daily nutritional support without unwanted side effects.\u003c\/p\u003e\u003ch2\u003eBenefits Supported by EFSA\u003c\/h2\u003e\u003cp\u003eThe European Food Safety Authority (EFSA) has approved several health claims for vitamin B3.

It is especially useful during periods of increased physical or mental demands.\u003c\/p\u003e\u003ch2\u003eNiacin vs. Niacinamide: Which to Choose?\u003c\/h2\u003e\u003cp\u003eVitamin B3 comes in two main forms: niacin (nicotinic acid) and niacinamide (nicotinamide). The main difference lies in their effect on blood vessels. Niacin can cause a temporary flush due to vasodilation, while niacinamide does not produce this effect. Therefore, niacinamide is the preferred option for those who wish to avoid this reaction. Both forms share metabolic benefits, but niacinamide is better tolerated at high doses. Source Naturals offers niacinamide in easy-to-take tablets, ensuring optimal absorption without discomfort.\u003c\/p\u003e\u003ch2\u003eRecommended Dosage of Vitamin B3\u003c\/h2\u003e\u003cp\u003eThe recommended daily dose of vitamin B3 for adults is approximately 14-16 mg, although needs may vary depending on diet and lifestyle. Each Source Naturals tablet provides 100 mg, a significantly higher amount than the reference intake. It is recommended to take one tablet daily with water, preferably with a meal, or as directed by a healthcare professional. This pack includes three bottles of 250 tablets, providing a supply for over two years at the indicated dose. Do not exceed the daily dose without consulting a specialist.\u003c\/p\u003e\u003ch2\u003ePossible Side Effects of Niacinamide\u003c\/h2\u003e\u003cp\u003eNiacinamide is considered safe and well-tolerated by most people. Unlike niacin, it does not cause flushing or itching. However, very high doses (generally above 500 mg per day) can cause mild gastrointestinal discomfort, such as nausea or headache. It is important to respect the recommended dose and consult a doctor if you are pregnant, breastfeeding, or taking medication. Food supplements should not be used as a substitute for a balanced and varied diet.\u003c\/p\u003e\u003ch2\u003eWhy Choose Source Naturals?\u003c\/h2\u003e\u003cp\u003eSource Naturals is a renowned brand in the supplement industry, committed to the quality and purity of its ingredients.
