Amino Acid Cocktail

Scientists at the University of Milan think they may have found the elixir of life.  By feeding mice a cocktail of amino acids (aminoisohezoic acid, isoleucine and valine) they prolonged their lives "significantly". 

Amino acids are the building blocks of protein. And the mice fed this cocktail didn't just live longer, they also benefited from an increase in the energy intake of their cells and an overall decrease in oxidation damage caused by free radicals. Their stamina also increased and coordination of their muscles improved.
