A recent study found that dietary supplements for weight loss may harm your health and that women in lower-income households are more likely to purchase them. The United States Food and Drug Administration (USFDA) states that some dietary supplements have been found to be dangerous or ineffective. A2012 study points out some of the facts and figures involved in the more than $37 billion U.S. annual dietary-supplement business. Dietary supplements include vitamins, minerals, herbs and amino acids purchased without a prescription. The USFDA cites such products as dangerous and/or ineffective ones that may have been compromised with unspecified prescription drugs, chemicals or banned substances.
The USFDA stated that the adverse health effects associated with WL products include cardiac arrhythmia and renal failure; MB products with testicular cancer and coronary artery disease; and SF products seizures and blood-pressure changes.
