The present invention provides novel methods of making a non-corrosive base solution for use as an alkalinity increasing agent and/or antioxidant. The present invention further provides novel compositions and methods which can be used to provide relief from disorders related to or complicated by acidosis or excessive free radical or other reactive oxygen species production including, but not limited to, gout, Lesch-Nyhan syndrome, hemochromatosis, Alzheimer's, amyotropic lateral sclerosis, arthritis, atherosclerosis, cancer, cataracts, chronic obstructive pulmonary disease, diabetes, cellulitis, coronary artery disease, heart failure, hypertension, inflammatory bowel disease, macular degeneration, multiple sclerosis, Parkinson's, Reynaud's phenomenon, reperfusion injury, pancreatic impairment, skin infections, Hepatitis C, methicillin-resistant Staphylococcus aureus and infection. The compositions and methods of the present invention additionally supply relief from microbial infections including fungal infections as well as prevent secondary infections. Additional compositions and methods are provided which employ a non-corrosive base solution in combination with a second alkalinity increasing agent and/or antioxidant, or other therapeutic agent to yield a more effective treatment tool against acidosis and/or excessive ROS production including free radical production useful to prevent or reduce acidosis and/or excessive ROS production or related symptoms or conditions associated with acidosis and/or excessive free radical production in mammalian subjects.
