good price

Posted by iHerb Customer on Sep 10, 2017 | Verified Purchase

Good product, i only wish i could easily break them in half, so i could take one half in the morning and one in later again on the day. Price is good though!

Thanks for your feedback!

Against Depression

Posted by iHerb Customer on Aug 19, 2017 | Verified Purchase

A friend told me that Niacinamide is helpful for people with depression. But higher doses are necessary. I hate to take antideresive grugs. For me it is 4 gramms daily which keep my mood bearable.

Thanks for your feedback!

For its price this is great. The pills are a bit hard to swallow. You can always spit though 😊
