I found myself able to be on the go since taking 3 -5 tablets of Niacin daily. Energised and not tired at all! Wonder product!

Thanks for your feedback!

Niacin flush is normal and not harmful.

It's not an allergic reaction, sadly the package doesn't mention this in its label, it could save an expensive visit to the ER. Read about 'Niacin Flush' before taking. Otherwise, a an extremely healthy supplement to take.

these made me flush a lot for 30+ minutes, but it only lasts a few days, and then you get used to it. Problem is, you have to take it religiously or the flush comes back.

Thanks for your feedback!

Cost effective, good size
