Lactoferrin for athlete's foot
Oral administration of bovine lactoferrin for treatment of tinea pedis. A placebo-controlled, double-blind study.
Mycoses. 2000;43(5):197-202.
A clinical study was conducted to evaluate the effectiveness of lactoferrin, which is a protein component of cow's milk, in the treatment of athlete's foot. Doses of either 600 mg or 2000 mg of lactoferrin, or a placebo was orally administered daily for 8 weeks to 37 adults who were judged to have mild or moderate athlete's foot. In the analysis limited to subjects with moderate vesicular or interdigital athlete's foot, dermatological symptoms scores in the lactoferrin-treated groups decreased significantly in comparison with the placebo group. The organisms isolated were Trichophyton rubrum and Trichophyton mentagrophytes. A mycological cure was not seen in any of the subjects.These results suggest that orally administered lactoferrin can improve the dermatological symptoms in some subjects with athlete's foot. The potential usefulness of lactoferrin as a functional food material for treating athlete's foot was seen for the first time in this study.
