We use a lot of supplements of this brand and like them as they are high quality. My parnts use niacinamide in higher dose to fight cancer, so i'm glad we've found this one from 1000mg- very potent. in just one pill. They take 2-3 a day altogether and vitamin B1 as well. The size of the pill is big, but it's not difficult to swallow. Niacinamide gives more cellular energy and no flush effect.

These tablets are vegetarian and definitely flush free. They are as sizeable (1000mg) as one might imagine, however, the design makes them easy to swallow.

I learned this stuff is great for slowing down phase 1 of the liver so I started taking it. It has helped a lot! I love the time release so it keeps it going all day and all night. (I take one on the morning and one at night.)

This tablet has helped me with my joint pain.Highly recommed to be taken by Arthistis patients and also joint pain.Will order soon a few more bottles.

Good price for such a high dose Couldn't find a better option so far. Although I live outside of the US, it was delivered much sooner than expected!

Taking this supplement (Niacinamide) with D3, B12 and Glutathione to combat my challenging melasma. Over months of intake of combination, I can clearly see improvement on my melasma and will continue using it from now on.

Niacinamide seems to help me with anxiety and sleep right before bed.

Gave this supplement to one of our pups with SLO. Seemed to help! good product.

Truly an excellent product! I'm very happy with the results!! The ZERO niacin flush makes a huge difference, too.

Great as a preventive measure for brain tumors as well as skin cancer.
