Anyone who looks into the legitimacy of the “RDAs” knows it is a sick joke. That is people are getting sick when they follow such poor advice. In one day of research I have discovered countless testimonials of people curing depression and other illnesses using high amounts of Niacin, up to 3 -7000 mg per day with great benefits. I read there is less than one death per year reported from Niacin overdose. That would be much higher than the therapeutic dose of 3-7000. It seems irresponsible to me to warn people not to supplement with this powerful healing vitamin. It could save their lives!

Nicotinamide has been discovered to lower occurrence of Basal Cell Carcinoma and Actinic Keratosis if taken in doses of 500 mg twice a day. The benefit ends when the nicotinamide is discontinued. This has been researched, studied and tested in Australia by Professor Diona Damian and her team at the University of Sydney. Dr Andrew Chen, a final year PhD student who worked with Professor Damian on the trial, won The Rising Star PhD Award in 2016 for Outstanding Cancer Research.

I used to take a lot of niacin because my family has high lp(a) and a lot of heart disease. I didn’t mind the flush, actually came to like it. But then my ears started hurting really badly, and that is harder to deal with. I’m thinking of dropping to a lower dose more often. But do you think niacin works for NAD+ if you don’t flush? I have a theory that the flushing is important for effectiveness.

Niacin doesn’t appear to be toxic until it’s prolonged and quite a ways over the insanely low RDA.
I have noticed the best benefits (for sleep, mood) from doses between 300-500mg/day.

I do agree that very high-dose Niacin CAN be toxic and that taking it over 500mg/daily wouldn’t be a good idea.

There is a good breakdown here: http://lpi.oregonstate.edu/mic/vitamins/niacin

“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)

Also, “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” (25)
