How It Works

When you are on the run or finishing an intense training session, your muscles need immediate access to essential amino acids to start the recovery process. Optimum Nutrition High Protein Shake RTD utilizes a bioavailable milk protein base that digests efficiently to feed your muscles and halt catabolism.

By delivering 25 grammes of protein in a convenient liquid format, it rapidly elevates circulating amino acids to promote muscle protein synthesis and support muscle repair. Because it is pre-portioned and shelf-stable, you get consistent, high-grade nutrition whenever your schedule demands it.

Recommended Use

Shake well before opening. Drink one bottle immediately post-workout to kickstart muscle recovery, or enjoy anytime during the day as a high-protein, satisfying snack between meals. Best served chilled. Once opened, keep refrigerated and consume within 24 hours.
