About eight hundred dietary supplements were sold over counter from the year 2007 to 2017 which contained illegal ingredients of drugs, says an analysis by Food & Drug Administration of the US. In 20 percent of those dietary supplements, many unapproved ingredients were found, says the study during JAMA network show on Friday. The addition of such prescription medicines in unknown concentrations makes it harmful for the users’ health, study reveals. Such products can severely affect the health owing to overuse, accidental misuse, underlying health problems, or mixing it with different medications, said the authors. About, 50 percent of the adults make use of dietary supplements which is a $35billion industry so far.
The authors reviewed database of FDA for 2007 to 2017, which is kept on the website of agency as resource for customers in order to increase public awareness and transparency. The researchers have performed new analysis which is independent of FDA. Many adulterated products, were offered for sexual improvements which included tadalafil, vardenafil and sildenafil, which are prescribed for issues like erectile dysfunction that can cause major damages to blood vessels when overused. The very common ingredient found in the adulterated weight reducing products was sibutramine, which is vanished from the market of US in 2010 as it caused cardiovascular problems and laxative phenolphthalein. Most of muscles gaining products have anabolic steroids that can cause mental, kidney problems as well as heart and liver problems.
As dietary supplements market is growing continuously in the US, it has been really essential to address such important public health factors, said the authors. Dr. Peter Cohen said that though FDA has found about 746 adulterated dietary supplements, it has recalled about half of those products. About 48 percent of those products were recalled, by leaving the rest of adulterated dietary supplements available to sale, writes Cohen in the editorial published during his study.
