MET-RX Partners with John Cena to Launch 44-Gram Protein Milkshake

MET-Rx has launched 44g High Protein Shake, marking the brand’s entry into the ready-to-drink category. The new lineup is available in three flavors: Strawberry Shortcake, Vanilla Milkshake, and Chocolate Milkshake. Each shake delivers 44 grams of protein, 6 grams of fiber, five key nutrients, and up to 2,500 mg of electrolytes per bottle, combining high-protein nutrition with recovery support.

The brand’s Level-Up campaign, anchored by multi-year brand ambassador John Cena, actor, entrepreneur, and former WWE wrestler, continues to evolve with this launch. The category expansion will be supported by exciting new content featuring Cena in an animated, video-game-inspired format.

“MET-Rx remains my go-to for recovery after any tough workout,” said Cena. “The new 44g shake packs high protein with fiber and electrolytes for recovery, making it easier than ever to get the protein and essential nutrients I need. Plus, they taste great!”

“MET-Rx’s new RTD shake is a real step forward in how we help people meet their protein goals, pairing high-quality protein with added benefits like hydration support, all in one convenient bottle,” said David Del Pozo, chief innovaiton officer at 1440 Foods. “Accessible nutrition matters more than ever, and this launch makes getting high-protein nutrition as effortless as grabbing a bottle.”
