Our History

In 1996, Andrew Weil, M.D., recognized the potential of the young medium known as the Internet to provide interactive tools that would promote healthy living. Shortly after the launch of his “AskDrWeil.com” website that year, he debuted a feature called the "Vitamin Advisor" that became instantly popular. It used a simple questionnaire - eight questions for men, nine for women - to recommend basic supplements that were appropriate for the taker.

In the summer of 2001, he expanded the Vitamin Advisor’s mission to include detailed questions about diet, lifestyle, and health history, and he created a Science Advisory Board to monitor nutrition science and make sure the recommendations were based on the latest research. Finally, he specified that the new Vitamin Advisor should not just recommend supplements - it should also allow visitors to purchase them in a convenient form.

After months of development, the re-designed Vitamin Advisor launched in November of 2001.

Dr. Weil insisted from the start that this tool must be offered with no obligation. Anyone was free to answer the questions receive a free supplement recommendation, which could be taken to a physician or retailer to be fulfilled. However, if the visitor chose to do so, he or she could order the unique supplements in convenient daily packs - these would be delivered fresh each month.  

The Vitamin Advisor clearly filled a need. From 2001 to 2013, millions of visitors filled out the questionnaire and received personalized recommendations. Through the years, the tool was regularly improved to provide more precise assessments and targeted supplementation – all informed by the latest in nutrition science.

In 2012, Tieraona Low Dog, M.D., joined the Vitamin Advisor team. A longtime associate of Dr. Weil’s, Dr. Low Dog chaired the United States Pharmacopoeia Dietary Supplements and Botanicals Expert Information Committee from 2000-2010 and now serves as the Chair of the Dietary Supplements and Botanicals sub-committee on safety, where she helps oversee the evaluation of the safety of commonly used dietary supplements.

As world-renowned authority on supplementation and health, she envisioned a major upgrade. Under her direction, the Weil Vitamin Advisor was expanded, refined and re-imagined to reflect the latest discoveries in nutrition science.

The new questionnaire covers not only the user’s basic nutrition needs based on lifestyle questions, but also inquires – and offers solutions – regarding specific health goals such as better sleep. More health-goal-oriented modules will be added to the Weil Vitamin Advisor on a regular basis. An extensive health check was developed to reduce the risk of someone getting a supplement that might interact with prescription medications, and to ensure that customers do not get too much of a particular ingredient

Dr. Low Dog worked with first-tier supplement manufacturers to create customized formulations available, for the most part, exclusively through the Weil Vitamin Advisor.

“The earliest incarnation of the Vitamin Advisor offered a great service to health-conscious consumers, but was restricted to offering only tablet and capsule formulations already available in the marketplace,” said Dr. Low Dog. “Later versions offered some customized tablet formulations. But the new Weil Vitamin Advisor was designed literally from the ingredient-level up. We created custom supplements, which in turn are combined with other supplements in customized packets, to create a coordinated health solution that just doesn’t exist anywhere else. I’ve very proud of the hard work that dozens of talented people have put into this product over the course of 18 months. If you’ve ever been confused or frustrated by the bewildering variety of supplements on the market, I urge you to visit the new Weil Vitamin Advisor.”
