I get better results with low doses of niacin (not niacinamide). NOTE: may not be suitable for hypothyroid conditions
I find I get better results taking small amounts of niacin instead (50mg or less), so will stick with that. I found 250mg of this to be way too much at once - took at night, had a fog-ache all the next day and was over-tired. Not the desired result at all. At this dose it depletes too many other things, necessitating their supplementation or increased doses to compensate - terrible if you've already had a difficult time trying to find a balance. Additionally, I've since read that niacin/niacinamide decreases thyroid hormone levels, which is true of my experience. In one small study - after a year of taking niacin, thyroid hormone levels had fallen significantly in each person. In another - thyroid hormone levels decreased in two people, and one of these two was diagnosed with hypothyroidism. Fortunately - when the niacin was discontinued for one month, thyroid hormone levels returned to normal. Please be careful. If this review was helpful to you, please click YES below - thank you.

Help for Alzheimer's
I read an article about curing Alzheimer's with niacinamide in mice (Second Opinion newsletter, February 2009) - decided to try it - the niacinamide has helped my Mother very much, she is calmer, more alert, speaks better, more like her old self, I highly recommend it. I plan to double her niacinamide dose.
