A method of safely administering to a subject a nitrate with a reduced side effect, the method comprising:

• combining a quantity of an inorganic nitrate with a quantity of an amino acid compound to produce a composition or a dietary supplement comprising an amino acid nitrate salt, wherein the combining of the inorganic nitrate salt with the amino acid compound reduces the side effect or toxicity of the inorganic nitrate;
• and
• orally administering to the subject the composition or dietary supplement, wherein the subject has reduced side effect or toxicity from the inorganic nitrate and the quantity of the amino acid compound is at least the quantity of the inorganic nitrate,
• wherein the side effect is selected from the group consisting of nausea, gastric distress, gastric ulcer, diarrhea, abdominal pain, and methemoglobinemia, and the amino acid compound is selected from the group consisting of agmatine, arginine, asparagine, aspartic acid, beta alanine, betaine, carnitine, citrulline, creatine, cysteine, glutamine, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, norvaline, phenylalanine, ornithine, proline, taurine, tyrosine, and valine.
