Aspects of the disclosure relate to compositions and methods for dietary management of certain conditions, such as infectious diseases. The disclosure is based, in part, on methods of identifying one or more single nucleotide polymorphisms (SNPs) in a subject and preparing a personalized report recommending a mixture of nutritional supplements and/or dietary aids based upon the presence of the SNPs. In some embodiments, the disclosure provides personalized compositions comprising nutritional supplements for dietary management of immune health and COVID support.

A germinant mixture includes a) a bile acid main germinant, b) an amino acid co-germinant, c) an edible spore solubilizing agent, and d) a divalent metal salt co-germinant. Also described is an oral pharmaceutical composition including the germinant mixture and a pharmaceutically acceptable excipient. A method of treating, decolonizing, and/or preventing C. difficile infection in the gastrointestinal tract of a patient in need thereof includes orally administering the germinant mixture or the oral pharmaceutical composition and an antibiotic that is active against C. difficile to the patient in need thereof.
