The present invention relates to the use of one or more nucleotides selected from the group consisting of GMP (guanosine monophosphate) and IMP (inosine monophosphate), a first amino acid selected from the group consisting of alanine, histidine and glycine or a mixture thereof; a second amino acid selected from the group consisting of proline and threonine or a mixture thereof; and furaneol for increasing the palatability of a foodstuff to a companion animal. The invention also relates to a pet food-stuff or supplement comprising one or more nucleotides selected from the group consisting of GMP and IMP, a first amino acid selected from the group consisting of alanine, histidine and glycine or a mixture thereof; a second amino acid selected from the group consisting of proline and threonine or a mixture thereof; and furaneol, and also to a method of increasing the palatability of a food-stuff to a companion animal.

An acetic acid-containing seasoning liquid includes acetic acid; at least one free amino acid selected from nine kinds of free amino acid groups consisting of valine, methionine, isoleucine, leucine, tyrosine, phenylalanine, histidine, lysine, and arginine; and a free amino acid other than the free amino acid groups. The acetic acid is contained in an amount of 0.1% by mass or more. A total content mass ratio of the nine kinds of free amino acid groups to total free amino acids is in a range of 0.20 to 0.70. A content mass ratio of the total free amino acids to the acetic acid is in a range of 0.01 to 0.30.

The present invention generally relates to compositions and methods for supporting exercise performance or activities of daily living. The compositions described herein are pharmaceutical or nutritional compositions suitable for enhancing exercise performance. The compositions are based on a specially formulated mixture of essential amino acids (EAAs) with additional components. The compositions target support of muscle protein synthesis and reduction of muscle breakdown during exercise, increasing muscle blood flow during exercise, decreasing the perception of fatigue by supporting optimal availability of neurotransmitter precursors, providing energy for rapids bursts of exertion during exercise, and maintaining adequate electrolyte balance during exercise.
