A method of treating metabolic endotoxemia comprising identifying a subject having post-prandial dietary endotoxemia and administering an effective amount of a spore-based probiotic. While any spore-based probiotic may be used, the probiotic supplement may comprise Bacillus indicus (HU36), Bacillus subtilis (HU58), Bacillus coagulans, Bacillus licheniformis, and Bacillus clausii. One or more of a level of blood endotoxin, triglyceride, post-prandial insulin, post-prandial ghrelin level, MCP-1, GM-CSF, IL-12p70, IL-13, IL-1beta, IL-4, IL-5, IL-6, IL-7, IL-8, and TNF-α is observed as being lower after spore-based probiotic supplementation when compared to placebo. At least one of post-prandial leptin and IL-10 is observed as being higher after spore-based probiotic supplementation when compared to placebo.
