Caprylic AcidSkip to the navigation
Caprylic acid is a saturated fatty acid containing eight carbon atoms, making it one of the family known as medium-chain fatty acids. Test tube and animal research has shown caprylic acid to have antibacterial,1 antiviral,2 and antifungal properties.3 Preliminary reports from the 1940s and 1950s indicated that caprylic acid may be effective against yeast (Candida) infections in humans.4 5
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
500 to 1,000 mg three times a day
Based on some historical use and theoretical research, caprylic acid is sometimes recommended as a treatment for yeast.
Test tube studies and case reports from the 1940s and 1950s indicated that caprylic acid (a naturally occurring fatty acid) was effective against yeast (Candida) infections of the intestines. However, these effects have not been studied or proven in controlled trials. Doctors sometimes recommend amounts of 500 to 1,000 mg three times a day.
