In most cases, your biochemistry will change enough in the span of three months to require new supplementation, dietary modifications and detoxification protocols. WellnessShoppingOnline.com offers high quality testing performed by Analytical Research Laboratories, and Dr. Lawrence Wilson who is one of the most experienced doctors will design your program. In addition, you will receive a personal consultation and supplementation plan with lifestyle and diet recommendations.
