NKO is a product that I have realized is very important for my overall health. It is great for women's hormones and moods, and I am in the menopausal years. I ran out of it for three weeks last summer, and became very depressed. I did not think about the Krill. After starting it up again, I immediately felt alot better, after just two days. I asked my neurolink practitioner if this had anything to do with it, and he said "absolutely." I've been fine ever since. I'm amazed that this has had such an impact. I won't be running out of it again.
