Muscle Milk Zero and Optimum Gold Standard Casein both focus on providing slow-digesting proteins for sustained muscle recovery. Muscle Milk Zero offers 15g of protein per serving, using a blend of casein and whey protein isolate, along with added vitamins and minerals. Optimum Gold Standard Casein delivers a higher protein content at 24g per serving, focusing solely on micellar casein for a more targeted and purer approach. The fat and carbohydrate content are both lower in Optimum, making it a leaner option overall.
Optimum Gold Standard Casein takes the win with its purer, more targeted formula, higher protein content, and better overall value. Its focus on micellar casein ensures a steady release of amino acids, while its lower carbohydrate and fat content make it an ideal choice for those managing macros more closely.
