    Healthy Bacteria for Women's Health Needs

    Billions of beneficial bacteria help keep our bodies healthy. And they're not just in our stomach - they also help maintain vaginal health. Ladies, get a probiotic supplement that caters to your unique needs with Undecylenic Acid by Thorne Research.

    Undecylenic Acid is a Thorne Research innovation that contains undecylenic acid in a base of pure, extra-virgin olive oil to support the establishment of healthy gut and vaginal flora.

    Our balance of digestive flora can become unbalanced for a variety of reasons including poor diet, insufficient digestive enzymes, oral contraceptive use, other medications and drugs, and more. Not only can this imbalance cause gastrointestinal discomfort and poor nutrient absorption, but it may also affect the balance of vaginal flora.

    In addition to probiotics, fatty acids may also support healthy gut flora, and undecylenic acid may be one of the most potent available for this purpose. Undecylenic acid is a natural component of human sweat and is derived commercially from castor bean oil. This fatty acid may be up to six times more useful than caprylic acid.

    For unique, double-duty beneficial bacteria support, order Undecylenic Acid.

    Very Effective Product:

    I am trying to kill fungus, and I like the product. It was recommended to me by a physician.

    I take on average, 3/day around meals plus Undecyn off and on. I think it helps with digestion and with containing bacterial overgrowth, at any rate, I am not suffering these days. This routine has supplanted my caprylic acid intake although I do still take a capsule at bedtime when I think about it. I do not want to be without the sf722 and undecyn because I they seem to work for me.

    This product is amazing for folks recovering from candida! It's one of the best anti-fungals out there. The only downside is you have to take a ton of them, and that it's made from animal products :(

    A product I have used for years!

    I started using this product many years ago when I was recovering from Poly-systemic candidiasis. It, along with a restricted diet and some other high-quality vitamin supplements, is what helped me turn the corner in my recovery and help me regain my health and my life. I now use it to maintain a healthy balance of intestinal flora.

    This has reduced my Candida! Amazing!

    Feel better on SF722

    My doctor is recommending supplements which will achieve proper balance and digestion for my unique body and disease issues, and this is one of them. I started with 1 SF722 after each meal, and built up to 4 capsules after meals for weeks. I feel great, and did not crave sweets as much as usual. I was advised to minimize sugar and carbs while on this in order to allow it to work. I believe this supplement has been key in helping me achieve a healthier ""gut"" flora and my digestive tract works more effectively and feels better.

    Top product for yeast infections

    My husband takes this product daily for systemic yeast infections (i.e. ""jock itch""). It has cleared his rash and relieved his back pain. (He continues to take it at night for the relief of back pain.) In addition to taking this supplement, he has curbed his sugar intake (even healthier ""raw"" sugars feed yeast, a fungi) and reduced ""stress.""
