Robert Keller MD products are absolutely state of the art! I take the OGF and the GRB energy drink. I feel their energy drink is the best of its kind on the market. Besides providing energy without the use of caffeine, it also enhances the body’s production of glutathione and nourishes the body all at the same time. As a bonus, it also tastes great! I feel Dr. Keller was way ahead of his time.
