Energy drink 'fuel hepatitis risk'

With regards to niacin (vitamin b3) :

Each had around 40mg of niacin (vitamin B3) - UK recommendations are that men have no more than 17mg a day and women 13mg.
People usually experience toxic symptoms only if they have more than 500mg, but in this man’s case, 160mg-200mg a day was enough to affect his liver. His symptoms disappeared when he stopped consuming energy drinks.

i was under the impression that hepatitis is a social disease.

Hepatitis is an inflammation of the liver.

> He already had an underlying liver problem, which doctors think increased the risk from his four or five drinks per day.
