At 500mg, this is immediate-release **niacin** (nicotinic acid) — the flushing, lipid-active form dosed for cholesterol support, not the ~16mg used for everyday energy. So if lowering cholesterol is your goal, the dose lands at the top of the clinical range and delivers a full effective amount.
The honest caveat: niacin does raise HDL and lower triglycerides. But the two definitive outcome trials, AIM-HIGH and HPS2-THRIVE, found no heart benefit added to statin therapy, and the larger one flagged a 55% jump in new-onset diabetes — so the cholesterol payoff you'd expect is weaker than the dose alone suggests.
Expect the niacin flush — temporary redness, warmth, and tingling that's harmless but startling at first; taking it with a meal softens it. At 500mg you're well above the 35mg upper limit for this form, so treat it as cholesterol-level dosing to clear with your doctor, not casual energy support.
