Undecylenic acid - potent fatty acid support of healthy gut and vaginal flora

Optimal gastrointestinal tract functioning is vital to the absorption of nutrients, elimination of waste, and proper immune function. Many health-care practitioners consider gut function and especially good gut ecology – maintaining a healthy balance of gut flora, the microorganisms that normally live in the digestive tract – to be a key component to overall health. Many situations can contribute to an imbalance in the microbial flora of the digestive tract, including an unhealthy diet, inadequate digestive enzymes, oral contraceptives, and the use of various prescription and OTC drugs. Increasing recognition is also being given in women's health to the relationship between gut flora and vaginal flora; i.e., a healthy balance of gut flora has corresponding benefit to the vaginal flora.

Fatty acids have been used for centuries to help maintain a healthy balance of the microorganisms that normally live in the gastrointestinal tract. In the last 50 years, fatty acids have demonstrated effectiveness in supporting a healthy gut flora in a number of studies.

Undecylenic acid (10-undecenoic acid) is an eleven-carbon, mono-unsaturated fatty acid occurring naturally in the body's perspiration. While several fatty acids have beneficial effects on the flora that naturally inhabit the gastrointestinal tract, undecylenic acid is the most potent.

A Thorne Research innovation, Formula SF722 contains undecylenic acid in a base of pure, extra-virgin olive oil. Formula SF722 aids in the establishment of healthy gut and vaginal flora and has been one of Thorne Research's best-selling products for over two decades.

This product really works, but

Posted by 5564075400975371890 on Sep 28, 2016

Theres only one drawback : its very potent and & ''synthetic'' in the way it works, so for many people ( including ) this can cause slight irritation of the skin and eyes. Really does the job well for candida. Should be combined with something that has some anti-bacterial properties as well ( ex coconut oil, oregano oil, etc ).

Best Anti-fungal supplement for Candida

Posted by 5579789213982681664 on Jul 01, 2016

This is the best antifungal available at the moment. The key is to drink lots of water, sweat using shower or far red sauna. Take a lot of Vitamin C and molybdenum glycinate to keep herx reaction in control. Also take a good multistrain probiotic with 20 Billion CFUs or more.
