Supreme Whey, from MET-Rx, is one of our most popular protein powders. And not without good reason. This high quality whey supplement not only tastes delicious, but is also great value for money.

Muscles are 70% water and therefore they cannot function at maximum levels whilst exercising if we are dehydrated. Met-Rx Isotonic Drink Mix is designed to provide a balanced formula of carbohydrates and electrolytes which are lost during exercise.

f you were to pick a single amino acid as part of your daily supplementation, L-glutamine powder would be a great choice. This is because Glutamine makes up approx 60% of the amino-acids in skeletal muscle, meaning the regulation of intramuscular glutamine has significant effects on skeletal muscle metabolism.

Glutamine actually helps you store muscle glycogen, the primary fuel source for intense exercise.
