Deep dives

Many dietary supplements inaccurately labeled and contaminated

A study found that approximately 30% to 50% of dietary supplements are incorrectly labeled and 20% may be contaminated. The most common areas of contamination are muscle-building, sexual enhancement, and weight loss supplements. The lack of pre-market testing by the FDA allows these issues to occur. Manufacturers violators of good manufacturing practices, and some do not register with the FDA. The study tested 57 products and found that 23 of them did not contain the labeled ingredient, and only 6 had the ingredient within 10% of the labeled quantity. 12% of the products contained FDA-prohibited ingredients, including a fedrin-related stimulant and a cardiac stimulant. It is important to be cautious when purchasing dietary supplements due to potential inaccuracies and contamination.
