The FDA defines supplements as products "intended to add further nutritional value to supplement the diet. Half of all adult participants in a survey in the mids said they took at least one supplement every day — almost the same percentage of Americans who took them two decades ago. Yet research has consistently found the pills and powders to be ineffective and sometimes dangerous.
In November, researchers at Harvard Medical School and independent product testing company NSF International identified four unapproved, unlisted stimulants in six supplements currently marketed for weight loss and fitness.
Evidence suggests the stimulants could be similar to ephedrine, a compound derived from ephedra, the dangerous and lethal weight-loss supplement that the FDA banned in Steve Mister , the president and CEO of the Council for Responsible Nutrition, a Washington, DC-based trade organization representing more than supplement and other companies, told Business Insider in September that this kind of adulteration harms the supplement companies who make legitimate products.

Over that period, 34 people died as a result of using supplements, according to a study published in the Journal of Medical Toxicology.
Six of the deaths resulted from the banned supplement ephedra, and three people died from homeopathic remedies. One person died after using yohimbe, an herbal supplement used for weight loss and erectile dysfunction.
Certain formulations of it can be prescribed to treat erectile dysfunction. Jamshidi said he knew many people who took a daily multivitamin and tried herbal formulations now and again when they were feeling tired or unwell and always withheld judgment.
But he remembers the moment he became wary of supplements: when the pregnant woman his team was monitoring began coughing up phlegm. When Jamshidi and his team realized their patient's tuberculosis was back, they asked if she'd started any new medications.
She said no, but the next day she arrived at the clinic with a small bottle of St. She said she had been taking the herbal remedy for the feelings of depression she experienced after her last pregnancy.
