Simultaneously, Met-Rx Food Bars are low in fat and 97% lactose free! Met-Rx takes the guesswork out of nutrition.

As a result, the exclusive Met-Rx formula contains more vital nutrients, key amino acids, vitamins, minerals and trace elements than you could ever hope to get from a regular 330-calorie meal.

So these Met-Rx Food Bars are meant to fill the gap.
