I have a book by Saul about vitamins.
He makes it all appear so simple. For example he claims nobody ever died from vitamins and so on.
This simplicity directly made me a bit sceptical.
Anyway, I read what he writes about niacin. He writes in one of his books that 3000mg niacin per day are absolutely safe.
So I considered taking niacin against depression.
But guess what, at the Linus Pauling Institute it sounds totally different. They mention cases where already 500mg were enough to cause liver damage!
I feel absolutely fooled by Saul. How can he make such claims? I think this is absolutely irresponsible! Now where I know that niacin is not "absolutely safe" I also can't believe anything else he wrote. His books are now totally useless to me. I am really angry about this.http://lpi.oregonstate.edu/infocenter/vitamins/niacin/
"Nicotinamide
Nicotinamide is generally better tolerated than niacin. It does not generally cause flushing. However, nausea, vomiting, and signs of liver toxicity (elevated liver enzymes, jaundice) have been observed at doses of 3 grams/day (84). Nicotinamide has resulted in decreased insulin sensitivity at doses of 2 grams/day in adults at high risk for insulin-dependent diabetes (49)."
"Niacin
Common side effects of niacin include flushing, itching, and gastrointestinal disturbances, such as nausea and vomiting. Hepatotoxicity (liver cell damage), including elevated liver enzymes and jaundice, has been observed at intakes as low as 750 mg of niacin per day for less than three months (84, 85). Hepatitis has been observed with timed-release niacin at dosages as little as 500 mg/day for two months, although almost all reports of severe hepatitis have been associated with the timed-release form of niacin at doses of 3 to 9 grams per day used to treat high cholesterol for months or years (24)"
