Methods of producing an amino acid nitrate supplement drink suitable for human consumption are provided. The methods comprise providing a solid nitrate salt of an amino acid and adding an amount of water to the solid nitrate salt of the amino acid to produce the amino acid and nitrate drink, wherein the amount of water is sufficient to dissolve the solid nitrate salt of the amino acid. In particular implementations, the solid nitrate salt of an amino acid is selected from the group consisting of: creatine nitrate, arginine nitrate, leucine nitrate, isoleucine nitrate, valine nitrate, cysteine nitrate, glycine nitrate, agmatine nitrate, beta-alanine nitrate, N-acetyl cysteine nitrate, aspartic acid nitrate, lysine nitrate, histidine nitrate, norvaline nitrate, ornithine nitrate, glutamine nitrate, citrulline nitrate, and betaine nitrate.
