Because the FDA does not regulate supplements it is important to select supplements that are approved by a third party for quality, purity and disintegration. Look for one of the seven following certifications: CL (Consumer Labs), UL, USP (The United States Pharmacopeia) or if you are an athlete, NSF and Informed-Choice, Aegis Shield Certified, BSCG Certified Drug Free marks. These marks must be present on the supplement bottle to ensure that they have been tested and approved. To see which supplements carry a certification visit their respective websites.
* Always check with your doctor before taking a supplement.
