Recommended Products

R4 is a dietary supplement based on 100% KYOWA quality branched chain amino acids, which provides a selective supply of essential amino acids derived from whey protein hydrolysate. R4 is made up of an excellent mixture of carbohydrates (Fructose, Maltodextrin and Dextrose), L-Carnitine and medium chain MCT fats, which is perfect for energy recovery. This exclusive formula is completed by a balanced combination of vitamins and minerals: the group B vitamins help to sustain energy metabolism and reduce tiredness and fatigue; vitamin B6 also aids efficient protein and glycogen metabolism. Vitamin C helps to protect the cells from oxidative stress.

After physical activity, it is important to quickly restore the nutritional metabolic balance and remove the metabolites that result from muscle fatigue. The rate of glycogen re-synthesis, which is the main energy source for the muscles during activity, is at its maximum in the hours immediately following physical activity. This is the best time to consume a specific product that quickly supplies all the nutrients that the body needs to make the most effective physical-muscular recovery.
