Yup, I give it to my old dog "Crackers" and I take it too---it is an excellent supplement.

I also find Vitamin D3--1000 units along with alot of B vitamins to help tremendously with sleep and mood.

Nowadays, Doctors and Nurse Practitioners will ask what supplements you take and will help you to take the right ones for you. They will take a CBC with Diff, and also levels of Calcium, etc, to make sure you are getting what you need.
