Monolaurin is a form of the fatty acid called lauric acid, which is found in large quantities in coconut milk and human milk. Some fatty acids, including lauric acid, reportedly have anti-bacterial, anti-fungal and antiviral properties. In test-tube studies, monolaurin has been shown to have antiviral activity against a number of viruses, including influenza and herpes. It seems to work by disrupting the lipid envelope of these viruses. Limited test-tube data also suggest that lauric acid may increase the production of immune cells in the body. There have been no clinical studies of monolaurin in PHAs. Monolaurin comes in capsules, however, lauric acid can also be found in raw or processed coconut.
