What would a reaction to niacin look like?


Answer by  Napasaurus (243)

Typically an adverse reaction or overdose of Niacin should be easy to identify. The skin will turn bright red and a consistent burning sensation will be felt, sometimes for upwards of eight to twelve hours. Dosages this high are often used in an attempt to prevent positive drug tests.

The most common adverse reaction to Vitamin B3 involves the skin, which can flush and become itchy for up to half an hour. Skin may become dry or develop a rash. Sometimes the skin can develop brown or black spots of pigment. Besides developing skin problems, you can get indigestion or liver problems, although that is less common.

Niacin reaction generally manifests as a flushing of the skin. The dosage required to cause this reaction varies by person. Extreme reactions can include itching and rashes forming on the skin. Time release versions of niacin are available, and this minimize flushing by slowing the bodies absorption of the niacin from the intestines.

There should be no reaction from normal food intake but if you take a niacin supplement, from 50g and upwards, then there is a possibility of harmless skin flushing and a slight rash. Nausea and vomiting are also possible.
