Abstract
Novel salts are prepared wherein the cation of the salt comprises a 1:1 ratio of a complex ion formed between zinc and methionine and any suitable anion, either inorganic or organic. The novel salts have the generic formula: [CH.sub.3 SCH.sub.2 CH.sub.2 CH(NH.sub.2)COO.Zn.sup.+.sup.+].sub.w X wherein X is an anion and w is an integer equal to the anionic charge of X. These novel compounds are useful nutritional supplements, both for animals and humans, in that they provide a readily-available source of the zinc ions necessary for dietary balance. In addition, certain of the compounds falling within the formula disclosed herein have been found to have therapeutic utility in the treatment of acne and colitis.
