Glyceryl monolaurate (GML), a monoglyceride derived from lauric acid, has garnered scientific interest as a potential alternative or adjunct to traditional antibiotics. Several in vitro and animal studies have demonstrated that GML exhibits broad-spectrum antimicrobial activity, particularly against Gram-positive bacteria such as Staphylococcus aureus and Streptococcus species. GML disrupts bacterial cell membranes, inhibits toxin production, and can interfere with biofilm formation, mechanisms that are distinct from many traditional antibiotics. These properties have led to its investigation as a possible tool to combat antibiotic-resistant pathogens.

Moreover, GML is generally recognized as safe (GRAS) for use in foods, which supports its potential for human applications. Some animal studies indicate that dietary supplementation with GML can reduce bacterial load and improve outcomes in models of infection. However, robust clinical trials in humans are lacking, and current evidence is insufficient to recommend GML as a standalone antibiotic replacement in medical practice. Its most promising applications may be as an adjunct to reduce antibiotic use or as a preventative agent in settings at high risk for infection. Overall, while scientific research supports the antimicrobial activity of GML, more high-quality clinical evidence is needed to fully validate its efficacy and safety as an antibiotic alternative.
