Weil Nutritional Supplements are based on stringent scientific research. Current, valid studies (published in peer-reviewed scientific journals) are the basis of our formulations, and all products are designed, selected, and approved by Dr. Weil and a team of physicians and researchers who are experts in the field of nutritional supplementation.

"Vitamins, minerals and other supplements won't compensate for a poor diet, but they can help fill nutritional gaps in a good one," says Dr. Weil.
