I first saw it reported here ( I would invite people to read this and the comments for themselves )
Apparently you can even kill deadly MRSA with high dose niacin! No need to spend hours in freezing cold water AKA Jack Kruse.
Nicotinamide is the version of niacin that I kind of dont like because it doesnt cause the skin flushing affect, personally I would stick with nicotinic acid, the flushing variety. REMEMBER the secret to niacin is to take it away from food and to fast for 5-6 hours after because it makes your serum FFA spike which in turns make you severely glucose intolerant and insulin resistant.
