Amino acid-containing composition for preventing or improving decrease in skeletal muscle mass in the elderly

摘要

The present invention provides an amino acid-containing composition for preventing or remedying a decrease in skeletal muscle mass of aged people, comprising L-leucine at a molar composition ratio of 35% or more with respect to total of essential amino acids. According to the invention, the protein anabolism of skeletal muscle can be promoted to prevent or remedy a decrease of the skeletal muscle mass of aged people.
