Many health-care practitioners believe that maintaining a healthy balance of gut flora is a key component of overall health.* In women's health, increasing recognition is also being given to the relationship between gut flora and vaginal flora; i.e., a healthy balance of gut flora has a corresponding benefit for the vaginal flora.* Studies going back 50 years demonstrate that fatty acids are effective in supporting a healthy gut flora.* The undecylenic acid in Formula SF722 is the most potent fatty acid – six times more effective than caprylic acid.* That efficacy has helped make Formula SF722 one of Thorne's best-selling products for more than two decades.*

Optimal functioning of the gastrointestinal tract is vital to the absorption of nutrients, the elimination of waste, and proper immune function.* Unhealthy diet, inadequate digestive enzymes, oral contraceptive use, and taking various prescription and OTC drugs can cause imbalances in the gut flora. Fatty acids have been used for many years to help maintain a healthy balance of the microorganisms that live in the gastrointestinal tract.* Formula SF722's undecylenic acid (10-undecenoic acid) is an eleven-carbon, mono-unsaturated fatty acid that occurs naturally in the body's perspiration.
