Niacin Powder (2 lb / 907 g) - Vitamin B3 Bulk Supplement, Immediate Release with Flush, Non-GMO, Vegan

The Niacin Flush: What It Is and Why It Happens

If you've never taken niacin before, you might be surprised by a warm, tingling sensation shortly after swallowing. This is the famous 'niacin flush' – a temporary reaction caused by vasodilation (widening of blood vessels) that increases blood flow to the skin. You may feel warmth, redness, or tingling on your face, chest, or arms. It is harmless, not an allergy, and typically fades within 30–60 minutes. The flush often becomes less intense with regular uses. Starting with a lower dose can help minimise discomfort.

Health Benefits of Vitamin B3

Vitamin B3 (niacin) offers several well-supported health benefits. According to European Food Safety Authority (EFSA) approved claims, niacin contributes to normal energy-yielding metabolism, helps maintain normal skin and mucous membranes, supports normal function of the nervous system, and reduces tiredness and fatigue. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.

What Is Vitamin B3 (Niacin)?

So what exactly is vitamin B3? Also known as niacin, it is a water-soluble B vitamin essential for converting food into usable energy. It plays a critical role in cellular metabolism, DNA repair, and the production of certain hormones. Niacin comes in two main forms: nicotinic acid (the form used in this supplement) and niacinamide (nicotinamide). The nicotinic acid form causes the flush, which many users associate with effective absorption.

How to Take Niacin Powder Safely

Each serving delivers 500 mg of vitamin B3 (as nicotinic acid). This is a high-dose, so start low and increase gradually to assess your tolerance. Mix the powder with water or your favourite beverage. Taking with food can reduce the intensity of the flush. Because niacin can interact with certain medications and medical conditions, consult your health care provider before beginning supplementation, especially if you are pregnant, nursing, or have liver issues. Store in a cool, dry place.
