Review: This is a life saver! - I was diagnosed with systemic Candida after 2 decades of eating mostly fast food and having no idea what gut flora was or how it affects your health. I was given an anti fungal prescription by my doctor, but the Rx was also poisoned my liver when taken at dosages high enough to kill my overgrowth. I spent hours and hours reading about what to eat and what supplements kill Candida, but weren't harmful to my body. After reading about UA (Undecenoic Acid) and its use in WWI and WWII to cure fungal growth in service members, I tried it. The directions call for 5 capsules, 3 times daily which gives you about 3.5g of UA. The articles I read about our service members called for 7g/day for 30 days, so I rolled with that amount. I'm not recommending anyone else take that dose. I'm simply telling you my experience. Along with a completely clean diet of non-GMO, non-antibiotic chicken, turkey, sourdough bread, almonds and almond butter washed down with PH-balanced water, I took 30 capsules a day, 10 capsules 3 times a day. In about 3-4 days, I could feel a difference. My energy levels started to come back, my strength started to come back, my short term memory even improved. The brain fog I had suffered for months was leaving and after 3-4 weeks, belly fat started disappearing. My uncharacteristic depression that had taken hold of me on and off as a result of my systemic Candida was gone. I also had shortness of breath from the lining of Candida in my lungs and that, too, is gone. After being on the Rx for almost 90 days and having to get my blood tested every 3-4 weeks to check my liver's health, I stopped taking it after a week using the UA and haven't even missed it. Mind you, during that 3 months, I felt no improvements in any of the areas I listed and it was harming by body. After 30 days with Thorne UA, I was the me I remembered years from ago. Vibrant, physically and mentally healthy, and no die off symptoms at all. Anyone that has had to deal with Candida die-off knows how miserable the headaches and body aches can be. In the past, if I strayed from my strict diet at all, I always had die-off symptoms while on the Rx. Because the UA killed off most of my Candida and does a phenomenal job at keeping it at bay, I no longer have any die-off symptoms and can eat out with my family from time to time without worrying about being 'hungover' for the next 24-48 hours. I have been using Thorne UA for over 3 months now and am so grateful to them for making such a wonderful, safe product. I have learned so much about gut flora, healthy eating and nutrition, I am now enlightening health care professionals that used to just push their choice of Rx on their patients and are now sold on Thorne UA. I have talked with several people in the last 3-4 months that have similar symptoms to mine. I always recommend they get tested at their Dr's office to see if they do have Candida and if their Practitioner isn't aware of Candida (many aren't), educate them. The friends that have been diagnosed and have used Thorne UA all agree that it is a life saver.
Review: SF722 is amazing! I've had sinus pain - SF722 is amazing! I've had sinus pain,migraines, depression, anxiety, and brain fog for most of my life. Two years ago I began to be truly exhausted, it was all I could do just to work 8 hrs and could barely keep up with anything else. I had a severe case of angioadema, and later a sinus migraine which caused so much pain I was begging doctors to operate...I was desperate. They gave me antibiotics (Bactrim) which made me feel worse..didn't think that was possible, and of course loads of painkillers that didn't really work. I finally got some now brand NAC and took two capsules, in about 10 minutes the pain diminished to almost nothing. I cried a little. At the time I had no idea it was a fungal/yeast infection in my sinuses (broken nose in my 20s) that was producing acetaldehyde causing horrible migraines and fibromyalgia in my neck and shoulders along with periodontal disease and other issues. The NAC is a precursor for glutathione and it also contained molybdenum and selenium. These are substances which allow your body to break down acetaldehyde (look up acetaldehyde - explains a lot). Pantethene, molybdenum, magnesium, Sulforaphane, liposomal vitamin c, and liposomal glutathione - both from seeking health (only brand of liposomals that worked for me so far) all break down acetaldehyde and support healing. Quercetin, a powerful antioxidant, is also extremely helpful for die off symptoms. It stabilizes mast cells to prevent histamine release wich is another byproduct of acetaldehyde. I also had a genetics panel done by 23andme and discovered I am homozygous for one of two major methylation genes 677 - I also had my doctor test me (insurance paid for it) to confirm it. It is estimated that 40 to 50 percent of the population has some degree of this genetic condition that causes so many problems, yeast overgrowth being one. Dr. Ben Lynch and Amy Yasko have websites regarding this. This is also a big deal because your body can't use vitamin b9 (folate) and needs the methylated version. Do your research before taking methylated b9...it can cause serious reactions in some people. My blood was very thick because of this which caused extreme fatigue. I was also b12 deficient which my blood tests didn't show correctly. What does all this have to do with sf722? It's all interrelated; yeast overgrowth, vitamin deficiencies, sluggish liver from toxin overload, hormonal imbalances, insulin imbalance, blood pressure too high or too low...the list goes on and on. Sf722 and the candida diet worked immediately to improve my sinuses and other issues. I research all these subjects relentlessly because your health and wellbeing is about taking responsibility for the state of your body and making it a personalized journey.

### ⭐⭐⭐⭐⭐ If you have a Candida problem, you should take this
*by H***N on April 2, 2026*

A review I saw on this product by T. Burton convinced me to give this a shot. I have severe candidasis that was very close to becoming systemic candida. I went on the candida diet, started taking Thorne's undecylenic acid, and taking monolaurin to boost my immune system. The combination has literally saved my life. As a side note, this product is a bit spendy, but well worth it. In order to make each bottle last a month, I take 5 in the morning and 3 in the afternoon. This amount has been working perfectly.
