NEW YORK (TheStreet) -- GNC Holdings (GNC) - Get Report reached an agreement with the New York State Attorney General on the vitamins and other supplements it sells, and that has given the stock a healthy 7% boost Monday.

That's good, said TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio. But reading "between the lines" he said that GNC and its ilk will now turn to vitamins and other supplements that come from the U.S., not cheaper ones from China that might not contain what the label says they contain.

That can only helpPerrigo (PRGO) - Get Report, he said on CNBC's "Stop Trading" segment.

Supplements coming out of China have taken a lot of market share from Perrigo on cost, Cramer said. But Perrigo -- headquartered in Dublin but whose supplements business is run out of South Carolina -- is "going to soar" 

Perrigo, an Irish-based company, makes its supplements in the U.S. and the stock "is going to soar" once stores like GNC turn to Perrigo's quality supplements.

So investors shouldn't be surprised if Perrigo turns out to be a winner in this decision between the New York State Attorney General and GNC Holdings, Cramer concluded.
