Formula SF722®: A Potent Undecenoic Acid for Gut and Vaginal Flora Balance

Thorne’s Formula SF722® is a best-selling supplement that provides a unique and powerful form of undecenoic acid to support a healthy balance of microorganisms in the GI tract and vagina. This well-researched fatty acid is derived from castor bean oil and is six times more effective than caprylic acid for promoting a healthy gut flora. It is an ideal foundational supplement for individuals seeking to support a healthy microbiome, particularly in addressing the challenges of intestinal and vaginal yeast overgrowth.*

How It Works: The Science of a Healthy Microbiome

The health of your gut and vaginal flora is dependent on a healthy balance between beneficial microbes and potentially harmful ones like Candida albicans.

Supporting a Balanced Flora
Formula SF722® delivers 10-undecenoic acid in a base of pure, extra-virgin olive oil. This potent fatty acid works by helping to disrupt the biofilms that can protect opportunistic yeast and bacteria. This action helps to inhibit the overgrowth of unwanted microbes, allowing beneficial flora like Lactobacillus to thrive. Therefore, it supports a healthy and balanced microbial environment in both the gut and the vagina.*

A Gentle and Effective Approach
Unlike some harsher botanical formulas, Formula SF722® is generally well-tolerated and provides targeted support without disrupting the body’s beneficial bacteria. Because of this, it has been a go-to choice for health-care practitioners for decades for promoting optimal GI and vaginal health.*
