About Us

Doctors Designs is the premier dietary supplement brand serving weight management providers and their patients. Through our decades of work in the nutritional supplement and weight management sector we have developed the highest quality, science based dietary supplements for medical weight management patients.

Our Philosophy

Our philosophy is quite simple, use what works!

We know your patients rely on you for results, and we don’t take this lightly. We select only ingredients based on pharmacognostical principles; we only use ingredients with identified active constituents, extensively studied, and when synergistically combined at active levels are known to exert appropriate and beneficial effects on the structure and function of the human body. No marketing hype. If there is no sound scientific basis for an ingredient, you will not find it in our products.


Our products are subject to all appropriate quality control procedures before we release them for sale. Our ingredient sources are carefully vetted, monitored and qualified before we conduct business with them.
