This occurs when nicotinic acid binds to receptors in the skin, causing blood vessels to dilate. While harmless, it can be surprising for first time users.\u003c\/p\u003e\u003cp\u003eENDUR Niacin IR employs a proprietary vegetable-based wax matrix tablet core that gradually releases nicotinic acid over approximately one hour. This slower delivery helps moderate the intensity of the flush whilst still providing the benefits of immediate-release nicotinic acid. Many users find that taking the tablet with food or after a meal further minimises the flush sensation.\u003c\/p\u003e\u003cp\u003eIf you prefer to avoid the flush entirely, you might consider niacinamide (nicotinamide) supplements. However, niacinamide does not contribute to cholesterol balance in the same way as nicotinic acid. For those specifically interested in the form supported by scientific research, immediate-release nicotinic acid remains the recommended choice.\u003c\/p\u003e\u003ch2\u003eWhy Choose Nicotinic Acid?\u003c\/h2\u003e\u003cp\u003eNicotinic acid—also known as crystalline niacin—is the only form of vitamin B3 that has been extensively studied for its effects on cholesterol and heart health. However, it is important to note that EFSA has not authorised health claims relating to cholesterol for niacin. Instead, niacin contributes to normal energy-yielding metabolism and the maintenance of normal skin and mucous membranes. It also supports normal functioning of the nervous system and contributes to the reduction of tiredness and fatigue.\u003c\/p\u003e\u003cp\u003eAs a water-soluble B vitamin, niacin is involved in over 400 enzymatic reactions, including DNA repair and cellular signalling. Ensuring adequate intake supports your body's fundamental processes. Note that other 'flush-free' forms, such as niacinamide or inositol hexanicotinate, have not demonstrated the same effects on cholesterol as nicotinic acid in clinical studies.\u003c\/p\u003e\u003ch2\u003eWhat Makes ENDUR Niacin IR Different?\u003c\/h2\u003e\u003cp\u003eENDUR Niacin IR (Immediate Release) provides 500 mg of nicotinic acid per tablet. Unlike many standard niacin supplements that release the entire dose at once, ENDUR utilises a proprietary vegetable-based wax matrix tablet core that gradually releases nicotinic acid over about one hour. This design helps moderate the intensity of the niacin flush whilst providing the benefits of immediate-release nicotinic acid.\u003c\/p\u003e\u003cp\u003eEach bottle contains 100 tablets, offering over three months' supply when taken as directed. This product is manufactured in the Pacific Northwest, United States at an FDA-registered facility that follows strict Good Manufacturing Practice (GMP).\u003c\/p\u003e\u003ch2\u003eHow to Take ENDUR Niacin IR\u003c\/h2\u003e\u003cp\u003eBecause 500 mg is a relatively high-dose of niacin, it is usually recommended to start with a lower dose and gradually increase to allow your body to adjust to the flush. This product is intended for individuals already accustomed to niacin or under the guidance of a health care professional. The typical serving is one tablet per day, preferably with a meal.\u003c\/p\u003e\u003cp\u003eTo minimise flush symptoms:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStart with half a tablet (if easily split) or a lower dose product first.\u003c\/li\u003e\n\u003cli\u003eTake the tablet with food, especially a meal that contains some fat.\u003c\/li\u003e\n\u003cli\u003eAvoid taking on an empty stomach.\u003c\/li\u003e\n\u003cli\u003eStay consistent with timing—taking it at the same time each day helps your body adapt.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eDo not exceed the recommended dosage unless directed by a health care provider.
