100% PURE Whey protein powder A high quality blend of whey protein isolate and whey protein concentrate, MET-Rx? Supreme Whey protein powder is perfect for those wishing to build and maintain a strong, healthy physique. Whey is one of the most absorbable forms of protein and MET-Rx? Supreme Whey is used by top athletes who demand results fast. Protein is essential in building lean muscle, strength and optimizing recovery and is also one of the most important nutrients for health, growth and well-being, especially when training. Even people trying to lose excess fat are aware of the excellent benefits of following a high protein, low carb diet and while some brands require you to ?top up? the calories or ?improve? the taste by adding milk, MET-Rx? recognises that some people find it hard to digest milk. MET-Rx ? Supreme Whey is one of the only protein drinks that are designed to be mixed with water and taste great. For those that feel Casein in milk is a benefit at bedtime, MET-RX ?Supreme Whey can be easily mixed with milk resulting in slower digestion. High concentration of BCAAs The very high concentration of branched chain amino acids (BCAAs) found in whey protein is of special importance to body builders and power athletes. BCAAs L-leucine, L-isoleucine and L-valine make up about one third of the total protein content of human muscle tissue. BCCA may help to increase endurance during exercise as well as improve strength.
