Tag: Liver damage from niacin

While niacin, or vitamin B3, is vital for converting food into energy, nervous system function, and skin health, consuming it in high doses via supplements can lead to significant side effects. Understanding these potential reactions is crucial before starting any high-dose regimen.

According to the National Institutes of Health, exceeding the Tolerable Upper Intake Level of 35 milligrams per day for niacin significantly increases the risk of adverse effects. This can lead to a condition known as niacin toxicity, where the body's systems become overwhelmed by an excess of this essential vitamin.

According to the NIH Office of Dietary Supplements, the Tolerable Upper Intake Level for niacin from supplements is 35 milligrams for adults, and intake beyond this can lead to high niacin levels. While a mild niacin flush is the most common sign, other, more severe symptoms can indicate potential niacin toxicity.

High-dose niacin supplements, particularly in the form of nicotinic acid, are known to cause a range of side effects, from the uncomfortable "niacin flush" to more serious issues like liver damage. Understanding **what are the signs of too much niacin** is crucial for anyone taking this supplement, whether for cholesterol management or other health reasons.
