Yes, there are regulations in place to ensure the safety and quality of health supplements in many countries. In the United States, for example, the Food and Drug Administration (FDA) regulates dietary supplements under the Dietary Supplement Health and Education Act (DSHEA). This includes requirements for good manufacturing practices, ingredient testing, and labeling standards to help ensure the safety and quality of health supplements. Other countries may have similar regulatory frameworks in place to oversee the production and distribution of health supplements.
