Regulators are cracking down on herbal supplements after determining that some of them might not actually contain any herbs.
New York Attorney General Eric Schneiderman announced an agreement on Wednesday with manufacturer NBTY, which sells popular supplement brands including Solgar and Nature Bounty.
As per the agreement, the company’s products will go through a more thorough screening process to ensure that they contain the proper ingredients.
USA Today reports that Schneiderman commissioned a study in 2015 that looked at various different supplement products, including some of NBTY’s. Using DNA barcoding technology to determine the contents of the supplements, it was unable to confirm that they contained the plants that their labels claimed they did. However, it did show that they contained fillers like powdered rice.
