Monolaurin is a monoester of glycerol and lauric acid, a medium-chain fatty acid abundant in coconut oil and human breast milk. In laboratory studies, it destabilizes lipid envelopes of certain viruses and membranes of gram-positive bacteria and fungi, and can inhibit bacterial toxin production. Small pilot studies and clinical observations have explored it for herpes simplex outbreaks, Staphylococcus aureus colonization, and Candida overgrowth, though robust randomized human data are lacking. People with recurrent infections or gut dysbiosis sometimes use it experimentally.

Who Should Consider

Food Sources

• Coconut oil (~50% lauric acid; partial conversion to monolaurin)
• Palm kernel oil (~50% lauric acid)
• Human breast milk (naturally occurring)

How It Works

Monolaurin integrates into microbial lipid bilayers and viral envelopes, increasing membrane permeability and leading to cell lysis. It also interferes with signal transduction and virulence factor expression in gram-positive bacteria such as Staphylococcus aureus, and may modulate host immune responses by altering cytokine production in vitro.
