Formulated to release gradually, this product aims to provide steady niacin availability while minimizing common short-term effects associated with immediate-release formulas. The tablets are crafted without unnecessary additives—gluten-free, vegan, and free of salt, sugar, starch, artificial flavors, colors, sweeteners, or preservatives—and manufactured in the USA by a long-standing family-owned company.\u003c\/p\u003e\n\n\u003ch3\u003eHow does extended-release niacin differ from immediate-release?\u003c\/h3\u003e\n\n\u003cp\u003eExtended-release niacin is formulated to release the active ingredient more slowly into the body compared with immediate-release forms. That slower delivery can reduce sharp spikes in blood levels and tends to lower the incidence of transient flushing for many users. ENDUR-ACIN uses an extended-release matrix to balance effectiveness and tolerability for daily use.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e500 mg nicotinic acid per tablet in an extended-release form\u003c\/li\u003e\n  \u003cli\u003eGradual absorption designed to moderate short-term side effects\u003c\/li\u003e\n  \u003cli\u003eConvenient once-daily or as-directed dosing for steady intake\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the product's key ingredients and purity features?\u003c\/h3\u003e\n\n\u003cp\u003eThe active ingredient is nicotinic acid (vitamin B3) at a 500 mg dose per tablet; there are no extra fillers or common additives that some users prefer to avoid.
