susan P. reviewed Qualia NAD+ | Beta Tester
It wasn't always a guarantee of extra energy thanks to my own lifestyle but I did notice better function in the setting of when I also made sure to take care of myself in other ways (like getting enough sleep!)
I know it's working
I typically take Qualia NAD+ after about a half hour after my empty-stomach, morning supplements. In about a half hour I will feel a warmth come over me. Being that I am usually cold, it is a good sensation. I know then that it is working!
Solid product
I was pleasantly surprised with the increase energy and lack of brain fog I felt while taking this product.
