ENDUR Niacin IR 500 mg – Immediate Release Niacin (Vitamin B3) Supplement – 100 Tablets

What Makes ENDUR Niacin IR Different?

ENDUR Niacin IR utilises immediate-release nicotinic acid embedded in a proprietary vegetable-based wax matrix. This matrix slows the dissolution of the tablet, releg the niacin gradually over approximately one hour rather than all at once. This unique delivery system may help reduce the intensity of the characteristic niacin flush while still providing the full benefits of nicotinic acid. Additionally, ENDUR Niacin IR is free of common allergens: no milk, egg, fish, shellfish, tree nuts, peanuts, wheat, corn, yeast, soya, gluten, salt, sugar, starch, artificial flavours, or preservatives. It is suitable for vegan and vegetarian diets.

What Is Niacin (Vitamin B3)?

Niacin, also known as vitamin B3, is an essential water-soluble vitamin that your body requires to convert food into energy. It plays a critical role in cellular metabolism, DNA repair, and the production of certain hormones. Niacin exists in two primary forms: nicotinic acid (the form used in ENDUR Niacin IR) and niacinamide (also called nicotinamide). While both support the same basic bodily functions, nicotinic acid is known to influence lipid metabolism.*

Key Benefits of Niacin Supplements

Niacin contributes to normal energy-yielding metabolism, normal functioning of the nervous system, and the maintenance of normal skin. It also helps reduce tiredness and fatigue. These are established health claims approved by the European Food Safety Authority (EFSA).

How to Take Niacin Safely

The recommended serving is one tablet (500 mg) daily, preferably with food. If you are new to niacin, start with a lower dose and gradually increase to allow your body to adjust. Niacin can cause a temporary flush – a warm, tingling sensation with redness – especially at the start. Taking the tablet with food and avoiding alcohol or hot beverages around the time of intake may help minimise this effect. If you are pregnant, nursing, taking medication, or have a medical condition, consult your health care professional before uses. Do not exceed the recommended serving.

Frequently Asked Questions

What is the difference between niacin and niacinamide?

Niacin (nicotinic acid) and niacinamide are both forms of vitamin B3, but they have slightly different effects. Nicotinic acid is known for its ability to influence lipid metabolism but may cause flushing. Niacinamide does not cause flushing but has not been shown to have the same lipid effects.

Will I experience flushing?

Flushing is a common but temporary side effect of nicotinic acid, especially with higher doses. The wax matrix in ENDUR Niacin IR is designed to slow release and may reduce the intensity. Starting with a lower dose and taking with food can help. If flushing persists, consider splitting the dose or consulting your health care professional.

How should I store this product?

Store in a cool, dry place away from direct sunlight. Keep the bottle tightly closed when not in uses.

Can I take this with other supplements?

Niacin can be taken alongside most other supplements, but always consult your health care professional to ensure there are no interactions, especially with medications that affect blood pressure or liver function.
