Highly concentrated amino acid solution

A nutritionally useful amino acid solution comprising:

• approximately 18 to about 22% branched chain amino acids (wt/wt);
• and
• a total amino acid concentration equal to or greater than 18% (wt/vol);
• and wherein
• the solution further includes nonbranched chain ionic and nonionic amino acids, the ratio (wt/wt) of the nonbranched nonionic to nonbranched chain ionic amino acids being 0.57 to 0.65.

A stable high concentration amino acid solution having a nutritionally useful amino acid profile comprising:

• at least the amino acids leucine, isoleucine, valine, glutamic acid, aspartic acid, lysine, histidine, arginine, phenylalanine, methionine, threonine, alanine, glycine, proline, serine;
• the ratio (wt/wt) of glutamic acid, aspartic acid, lysine, histidine, and arginine to phenylalanine, methionine, threonine, alanine, glycine, proline, and serine being 0.57 to 0.65;
• and
• the ratio of (wt/wt) of glutamic acid, aspartic acid, lysine, histidine, and arginine to phenylalanine, methionine, threonine, alanine, glycine, proline, serine, leucine, isoleucine, and valine being approximately 0.45.
