The amino acid L-leucine tells the body that it can somewhat boost its necessary repair processes after your training. This characteristic made Berry de Mey Nutrition decide at an early stage that L-leucine would be part of our selection. But we did not suffice at that. By making Leucine ProElite we have made a supplement that enhances the operation of this special amino acid and that intensifies the uptake of amino acids from proteins at several levels: not only in the muscles but also in the stomach. Leucine ProElite is designed to be taken during protein rich meals and protein shakes. It makes your body more efficient in dealing with those proteins.
