In the United States, the Food and Drug Administration (FDA) does not regulate dietary supplements the way it regulates prescription medications. As a result, some supplement products may not contain the ingredients listed on the label.
When choosing a supplement, look for products independently tested or certified by organizations such as NSF, U.S. Pharmacopeia, or ConsumerLab.com.
For personalized guidance, consult your healthcare provider, registered dietitian nutritionist (RD or RDN), or pharmacist.
