General Suggestions for Using Weight Loss Supplements
If you do use weight loss supplements, be aware that the vast majority of products sold as diet supplements are not regulated by the FDA. To make sure that the product you are purchasing has undergone quality control testing, look for diet supplements that bear a United States Pharmacopeia (USP) seal or that have passed assembly on the ConsumerLab.com website.
Be sure to ask your doctor about taking weight loss supplements before you use them. Avoid products with excessive levels of caffeine, which can cause side effects, such as increased heart rate and blood pressure.
