Abstract:
[Problems] Amino acid composition with substantially no side effects which can not only efficiently supplement energy but also elevate the motor function. [Means for Solving Problems] Energy-imparting amino acid composition or amino acid solution containing glutamine comprising proline, alanine, valine, isoleucine, lysine and the glutamine. The energy-imparting amino acid composition is superior to the conventional amino acid compositions containing no glutamine in the energy supplementation and the motor function.
