Tag: 500mg niacin

According to a randomized, placebo-controlled study involving healthy volunteers, a single 500mg dose of immediate-release niacin on an empty stomach can cause flushing with an average duration of about 75 minutes. This temporary side effect, often accompanied by a prickly or burning sensation, is a common reaction for those taking higher doses of the vitamin.

The Tolerable Upper Intake Level for niacin from supplements for adults is 35 milligrams, meaning a 500mg niacin dose is significantly higher than the recommended daily limit and should not be taken without medical guidance. This comprehensive guide explores whether 500mg niacin is too much and delves into the potential risks and benefits associated with this high dosage.
