ENDUR Niacin IR (Immediate Release) Nicotinic Acid 250 mg – 100 Tablets

What Is Niacin and Why Does Your Body Need It?

Niacin, or vitamin B3, is an essential water-soluble vitamin that plays a vital role in converting the food you eat into usable energy. It also supports the maintenance of normal skin, mucous membranes, and psychological function, as authorised by the European Food Safety Authority (EFSA). Your body cannot produce niacin, so you must get it from your diet or supplements. ENDUR Niacin IR delivers 250 mg of immediate-release nicotinic acid per tablet, a form that dissolves gradually over about an hour to help reduce the common flushing sensation. This makes it a practicable choice for incorporating niacin into your daily routine.

How to Take ENDUR Niacin IR Safely

The recommended dietary allowance (RDA) for niacin varies, but therapeutic doses for supporting metabolism often start at 250 mg daily. Begin with one tablet of ENDUR Niacin IR each day, ideally with food to minimise any stomach discomfort. Avoid taking it with hot drinks or alcohol, as these can increase the likelihood of flushing. If you are new to niacin, you may wish to start with a lower dose and gradually increase under medical guidance. Do not exceed the recommended dosage unless advised by your health care professional.

Niacin vs Niacinamide: Which Form Is Best for You?

When choosing a vitamin B3 supplement, it helps to understand the difference between the two main forms: nicotinic acid (as in ENDUR Niacin IR) and niacinamide. Both forms provide the essential vitamin B3 activity and contribute to normal energy-yielding metabolism, as well as the maintenance of normal skin and mucous membranes, as authorised by EFSA. However, nicotinic acid is associated with a temporary flushing sensation due to vasodilation, while niacinamide does not cause this effect. Nicotinic acid has been more extensively studied in relation to lipid metabolism, although EFSA has not approved a specific claim for this. ENDUR Niacin IR uses immediate-release nicotinic acid to deliver a high-quality supplement that supports your overall nutritional needs.

Understanding the Potential Side Effects

Niacin is generally well tolerated, but high doses—typically above 50 mg—can cause a harmless flushing reaction: redness, warmth, or tingling of the skin. This sensation is temporary and often diminishes with continued uses. The immediate-release design of ENDUR Niacin IR helps minimise this effect by releg the active ingredient slowly. Other occasional side effects include mild gastrointestinal upset, dizziness, or headache. If symptoms persist or become bothersome, stop taking the product and consult your doctor. Niacin may interact with some medications, including statins and blood pressure treatments, so inform your health care provider about all supplements you take.
