This 500mg **niacin** tablet is plain nicotinic acid — the one form of B3 that actually shifts your lipid profile, raising HDL and lowering triglycerides. At this strength it's working as cholesterol support rather than basic nutrition, and 500mg sits at the top of the studied range for that purpose.
Expect flushing. Nicotinic acid causes warmth and skin redness above roughly 30-50mg, so 500mg will likely trigger it at first — harmless but uncomfortable, and taking it with food helps.
One honest caveat: the two largest trials (AIM-HIGH and HPS2-THRIVE) found no drop in heart events when niacin was added to a statin, and flagged higher diabetes risk at gram-level doses. If you're on a statin or have liver concerns, talk to your doctor before starting.
