Lauric acid, a saturated fatty acid predominantly found in coconut oil and palm kernel oil, has demonstrated antifungal properties in several in vitro studies. Athlete's foot (tinea pedis) is a common fungal infection typically caused by dermatophytes such as Trichophyton species. Research shows that lauric acid can disrupt the lipid membranes of certain fungi, leading to cell death. While these findings provide a mechanistic rationale for its potential use, most evidence comes from laboratory experiments rather than clinical trials in humans. A handful of small-scale studies and anecdotal reports suggest that topical application of coconut oil (rich in lauric acid) may help manage minor fungal infections, including athlete's foot, but rigorous, large-scale clinical trials are lacking. There is limited peer-reviewed research specifically evaluating purified lauric acid against dermatophytes in vivo or comparing its efficacy to standard antifungal medications.

In summary, while there is a plausible scientific basis for using lauric acid to support the treatment of athlete's foot, the quality and quantity of clinical evidence are currently low. Its use is therefore best described as having preliminary scientific support, with more robust human studies needed before it can be considered a reliable or primary treatment.
