Optimum Nutrition Gold Standard 100% Casein Slow down the rate of protein digestion – not your performance! Gold Standard 100% Casein by Optimum Nutrition contains – as the name suggests – 100% of the dairy protein Casein to help with recovery, boost muscle growth and reduce muscle breakdown while you sleep. This slow-digesting protein releases amino acids slowly over a long period of time. This process can help your cells synthesize protein during times when your body might normally be breaking down its own muscles to energise itself. While athletes and bodybuilders use fast-digesting protein immediately before and after their workout to help refuel recovering muscles, slow-digestion is more beneficial at other times including bedtime when your body typically goes for hours without food. Slow-release protein. 24g of anti-catabolic micellar casein per serve. 5g BCAAs per serve. Over 5g glutamine & glutamic acid per serve. Optimum Nutrition Gold Standard 100% Casein is “anti-catabolic” and helps reduce muscle breakdown, making it the perfect slow-release protein to add to your supplement stack. It is also rich in antioxidants and prohibits the rise of dangerous free radicals. Optimum Nutrition Gold Standard 100% Casein contains essential and non-essential amino acids, as well as the BCAAs L-Leucine, L-Valine and L-Isoleucine plus 5g Glutamine & Glutamic Acid per serving for optimal regeneration of damaged cells and recovery. Nutritional Information (Based on Chocolate Supreme flavour) Directions of Use Add 1 heaping scoop of Gold Standard 100% Casein to your shaker cup and then pour in 295mL-354mL of your preferred beverage. Cover and shake for 25-30 seconds.
