The makers of an over-the-counter weight-loss product have suspended sales following accusations the product contains but does not list an ingredient banned by the NFL.

"We've received notice of the problem with the NFL," the makers of StarCaps said in a statement released by e-mail Thursday.

Saints players Jamar Nesbit and Deuce McAllister say they tested positive for Bumetanide after using StarCaps. Nesbit, who filed suit against StarCaps this week, and McAllister are among six to eight players under investigation by the league for taking a diuretic, considered a masking agent for steroids.

A person familiar with the case provided the number of players involved and spoke on condition of anonymity because the players are appealing.
