NSF International certifies nearly 600 products as part of their Certified for Sport® program. They also randomly test a number of products each year as part of their market surveillance or in partnership with different organizations and sports bodies.
Last year, NSF found 41 products in the market that failed athletic banned substance (ABS) testing. These were adulterants not listed on the product label. Three of these had voluntarily submitted to NSF.
