Fatty acid support for a healthy balance of gut and vaginal flora.

Formula SF722 contains undecylenic acid, the most potent of the fatty acids that studies have shown can be effective in maintaining a healthy balance of gastrointestinal and vaginal flora.

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.

iHerb Customer Reviews

The Product Works!

Posted by iHerb Customer on April 2 2018 | Verified Purchase

I started off slowly with 2 x 3 times a day and I had a couple of days where I was feeling really bad. Now I am up to 5 x 3 times a day and I am feeling much better. I am up to my 3rd bottle. Highly recommend.

Thanks for your feedback!

It seems to be working!

Posted by iHerb Customer on March 12 2018 | Verified Purchase

It is very strong. I had a migraine with vomiting the first day taking 4 pills so work yourself up to the full dosage. It's been a week now for me and I can feel the effects already on my joint pain and other symptoms of candida. Too soon to really tell the extent this will help, but so far so good. I am using it as recommended by the Candida Plan, including sweating. I am on a stricter AIP diet at the same time. I am hoping for remission from arthritis. Big thanks to iHerb for their friendly international shipping rates.

This product has changed my life!!

Posted by iHerb Customer on February 15 2018 | Verified Purchase

I have been at war with systemic Candida for over 12 months after being misdiagnosed with different ailments for years. I have tried everything, even pure gum turpentine which was meant to be a miracle cure for all parasites. I could not heal myself even with a very clean diet of no grains, no sugar, no dairy or nuts. As soon as I started the SF722 I could feel a big change happening and I am finally winning this war at last. I would also recommend daily coffee enemas as a must to keep your digestive system free and flowing.

Not For Sensitive Stomachs

Posted by iHerb Customer on February 2 2018 | Verified Purchase

Very disappointed with this product after reading so many good reviews. I made sure to take it with food to prevent any stomach discomfort but had to stop it after four days of only taking 2 pills a day. Caused acid reflux and burning stomach pain. Also made my oral thrush a lot worse, I think because it has thrown my stomach so out of balance. Now on top of Candida I am having to deal with trying to get my stomach back to normal. Very annoyed. This product should have a warning on it.
