Rating (out of 5): 2

Monolaurin is a monoglyceride derived from lauric acid, which is found naturally in coconut oil and breast milk. It has attracted scientific interest due to its antimicrobial properties, particularly against certain bacteria. Laboratory (in vitro) studies have demonstrated that monolaurin can disrupt the lipid membranes of various gram-positive bacteria, such as Staphylococcus aureus, Streptococcus species, and Helicobacter pylori. The mechanism involves the integration of monolaurin into the bacterial cell membrane, leading to structural disintegration and cell death. These findings provide a plausible biochemical basis for its antibacterial activity.

However, while the preclinical evidence is promising, there is a lack of robust human clinical trials evaluating the effectiveness of monolaurin in treating or preventing bacterial infections. Most of the available data comes from laboratory or animal studies, and it is uncertain how these results translate to real-world use in humans. There are also no widely-accepted guidelines or regulatory approvals for using monolaurin as a treatment for bacterial infections.

In summary, monolaurin’s use for bacterial infections is supported by laboratory research, but its clinical efficacy and safety for this purpose in humans remain unproven. Thus, while the scientific rationale exists, the current level of evidence is limited, justifying a moderate-low rating (2 out of 5) for its use in this context.
