iHerb Customer Reviews
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.

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.
High quality niacinamide

These capsules are easy to swallow and I can feel the effect within minutes. Niacinamide counters methylation (so good to take if you feel hyperactive/overmethylated), but you don't want to slow down methylation too much either. So 250 mg is a great dosage. 500 mg capsules are less flexible and it's unnecessary to take that dosage if half the amount will do the trick.

I had holistic testing done on my husband and niacinamide showed to be needed for his condition. It is very helpful for him, very calming, has helped to heal his esophageal condition.
