Undecylenic acid is a monounsaturated fatty acid that comes from castor oil. It’s often used in creams and ointments to treat fungal infections like athlete’s foot and nail fungus.
We are learning more and more about the importance of the gut microbiome. This complex ecosystem plays a critical role in digestion, immunity, nutrient absorption, and overall health. The bacteria, fungi, viruses, and other microorganisms that live in your gut help keep you healthy.

This article explores the evidence about whether undecylenic acid negatively impacts beneficial gut bacteria.
