If I understand the study correctly, they were giving the rats 800mg and 4grs PER KILO of bodyweight. Nobody takes such large doses of niacin. Not even close. If my understanding is correct, that study is not of any clinical relevance for us.

Doses of more than 4.5 grams daily can result in hepatotoxicity in humans, I cannot even imagine what 800mg/kg can do. Probably kill you with one single dose.
Ok haidut thanks for clarifying. 80mg/kg is still, averagely speaking, inside the hepatotoxic doses. 4.5 grams for a person of let's say 70 kg is 64mg/kg, thus 80 mg/kg is far beyond safe limits.This was in mg/kg of diet. So, to get the mg/kg bodyweight dose simply divide by 10, which gives 80mg/kg to 400mg/kg range. The first dose is probably relevant for humans, but the second one is too high and potentially toxic. Also, even though the study is niacin I don't see why the same results would not also be achievable with niacinamide.

Edit: There have been reported cases in medical literature of hepatotoxicity with 3gr dosage, so NOBODY should be even close (averagely speaking again) to 80 mg/kg
Thanks again haidut. So I eat up my words LOL.This dose is for rats. So, the 80mg/kg has to be scaled down to a human dose. The HED of 80mg/kg is about 13mg/kg for a human, which means about 1g for a 75kg human. Not a low dose but certainly not hepatotoxic either.
