Muscle Milk, the original ready-to-drink protein shake brand with nearly 30 years of nutrition expertise, announced the complete reformulation of its protein shake lineup -- now made with ultra-filtered milk, delivering 26-42 grams of complete protein per serving with no artificial sweeteners, flavors or added colors and half the ingredients of the previous formula.

Muscle Milk's reformulation meets the moment with convenient shakes made with complete protein from ultra-filtered milk with no artificial sweeteners, artificial flavors, or added colors.

Real ultra-filtered milk is a complete protein, containing whey protein, a fast-acting muscle building protein, as well as casein, a protein that is more slowly digested to support on-going muscle support. Each shake is crafted with half the number of ingredients of the previous formula and delivers the protein consumers expect from Muscle Milk, with 26 grams in the standard subline and 33-42 grams in the Pro subline.

The result is a smooth, great-tasting shake that helps support healthy muscles. Muscle Milk is now the only national ready-to-drink protein shake made with high quality protein made from real ultra-filtered milk and no added colors, no artificial sweeteners, and no artificial flavors. It is available in indulgent flavors, including Chocolate, Vanilla Crème, Cookies 'n Crème and Strawberries 'n Crème.

"Protein has never been more popular, but it's also never been more confusing," said Turk Budak, Muscle Milk senior director at PepsiCo. "We saw an opportunity to simplify the experience for consumers. With our new formula, we're delivering high-quality protein from real ultra-filtered milk, with no artificial sweeteners, flavors or added colors and the great taste people expect from Muscle Milk. This is the formula Muscle Milk has always been building toward; great tasting with fewer ingredients and built for how people actually use protein today."

The reformulated Muscle Milk protein shakes are available at retailers nationwide, including grocery, mass and convenience stores, as well as online. The lineup includes 11-ounce cartons and 14-ounce bottles, with multipack options also available.
