“The physical demands of years in the NBA had taken a real toll on my body. My energy levels had dropped. With Douglas’s systems, the change in my health was impressive–and I could see that it was actually a change at the cellular level through the testing they provided. My performance improved dramatically, and I continue to use his nutritional formulations on a daily basis.”

“Here is my 5-star review on Mr. Douglas D. and Optimal Health Systems…”

“In the world of natural healthcare and metabolic nutrition, I have found no better mentor than Douglas. I’ve attended many of his lectures, listened to his videos, spoken with him in person, and always walked away feeling optimistic and excited about the products and protocols he’s developed. It’s one thing to know about health and another to implement the practices necessary to maintain it. Douglas D. has made it easier for me to explain and motivate my patients to take on the challenge of improving their health and as a result, the health and wellbeing of their families and loved ones!”
