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 needs improvement

Posted by 5715424124926484160 on Dec 01, 2016

The product is difficult to take in case of damaged stomach mucosa. This problem might be corrected by adding some substances that would help the patients to tolerate it better.

I'm taking the pills for 3 weeks already and although I didnt kept a strict diet against candida, i've got no signs of it back in my organism! I will be back with a review after I the treatment will be over. Fingers crossed!

Great Product

Posted by 5080207170725383535 on Oct 28, 2016

I have not been officially diagnosed with candida but started to suspect it was linked to my chronic UTI issues, and I have thrush very often. I started on this and there has been a marked improvement, in what I would suggest isnt even a bad case. Im using it in conjunction with oregano oil and marshmallow root and have finally kicked an infection thats lurked for 8mo. Have just purchased a second bottle and cleared my diet of sugar and refined carbd so should improve further. I experienced no die-off symptoms but know for a fact its kicked my thrush.

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 ).
