Caprylic Acid, Undecylenic Acid And Candida Yeast Infections

My Two Secret Weapons To Fight Candida

Many organic fatty acids and medium chained triglycerides (MCTs) are fungicidal and have been used literally for centuries as antifungal and antimicrobial agents. It was centuries ago discovered that soaps made up from fats were great cleansers, but only 50 years ago that they had other properties about them apart from cleansing; they were also antimicrobial and antifungal. Caprylic acid is an MCT that comes from the coconut and undecylenic acid is a monounsaturated fatty acid that comes from the vacuum distillation of the castor bean. Let’s take a look at both and then I’ll explain why I like using them, especially when combined with GSE (grapefruit seed extract) and other antifungals.

After treating many candida patients over the past twenty seven years, one tends to experiment and try different products out. You use and recommend what works and tend to move on from those products that give poor or average results. Caprylic acid and undecylenic acid have now become some of my favorite and key anti-candida products, because they effectively inhibit and kill the growth specifically of candida yeast infections in the small and intestine and are very well tolerated – without creating very strong reactions in patients. I like to use what works and stop using products that give consistently very average results, this combo works, but even more so when carefully combined with several other key antifungals as you will see.

Beware Of Die-Off With Many Yeast Infection Supplements

Die-off is also known as a Herxheimer reaction. You will often find that successful candida treatment can cause in many cases, but certainly not all cases, the rapid death of large numbers of yeast organisms, during which time great amounts of toxins are released from the dead candida microorganisms.  These toxins cause problems in their own right, but are often attacked by an over zealous immune system, and can also cause allergies in many people. In my clinical experience, I have found that caprylic acid and undecylenic acid do not cause this die-off that so many talk about, and this is something I have witnessed with many patients in my clinic taking all manner of candida products. Of course not everybody who takes these acids will avoid a reaction, but in my experience it is much less common.

Caprylic Acid and Dr. William Crook

Caprylic Acid is designed to nutritionally support the needs of those who want to maintain optimal balance in their friendly flora; it has anti-fungal properties and is widely recognized as one of the key candida supplements.
Dr. William Crook, author of the famous book on internal ecology, “The Yeast Connection”, first made caprylic acid popular. Dr. Crook found caprylic acid to be the most effective anti-candida supplement in the 1980’s, and today it is still just as effective, I believe that there is little need to take the latest “scientific discovery”, chances are you are most probably paying more than you should for a product without the impressive 50 year track record of caprylic acid. My Candida Crusher product contains high-grade caprylic acid; so do keep an eye out for the new product release through candidacrusher.com

Undecylenic Acid Or Caprylic Acid?

We once used to recommended just caprylic acid as a stand-alone candida treatment, and then just undecylenic acid as a stand-alone treatment, but have since discovered that a combination of undecylenic acid and caprylic acid to be a much more effective product combination in most all candida cases. My naturopathic clinic has tried well over one hundred candida kill products and I’ve consistently found undecylenic acid and caprylic acids when used on their own or combined to be considerably less effective than when grapefruit seed extract was used in addition. So now I tend to recommend the combination of all three: undecylenic acid, caprylic acid AND grapefruit seed extract. A killer triple combination, and one I’ve recommended many times over because it just works.

I think I’ve discovered why this is such a potent combo, it’s because the combination of different fatty acids together with the potent anti microbial and anti fungal action of GSE have a powerful broad-spectrum effect on the many (19) different species of candida as well as the literally hundreds of other strains of yeast and bacteria which populate the gastrointestinal tract of many patients with chronic yeast infections. Do you really need the latest whiz-bang enzymatic product? I don’t think so; you just need to figure out the right combination of nutrients that have proven themselves over the past 50 years in therapy.

Caprylic acid inhibits the growth of detrimental yeasts such as candida albicans within the intestines.  It exerts this effect via its incorporation into the cell membranes of yeasts, the cell membranes then rupture that effectively kills the yeast cell. Caprylic acid is an 8 carbon-chained MCTs (medium chained triglycerides), and MCTs have an excellent stability of oxidation, and most top quality dietary supplements containing this acid have a two-year shelf life. Capric acid is similar to caprylic acid, but is a 10-carbon chained MCT, and the best candida formulations will contain both of these fatty acids. Besides being great antifungals, caprylic and capric acids are also beneficial in treating bacterial infections. Due to their relatively short chain length they have little difficulty in penetrating fatty cell wall membranes, hence their effectiveness in combating certain bacteria, such as Staphylococcus aureus and various species of Streptococcus.

Always Looking Out For The Latest And Greatest?

Some practitioners tell me that garlic, caprylic acid, grapefruit seed extract and even Lactobacillus acidophilus are all old hat and that it’s time to “upgrade” the candida product lines I use in my clinic. Such opinions generally stem from dietary supplement wholesalers who convince their customers (the health-care professionals) that the most effective products are the latest ones they release every year. I don’t like entertaining sales reps that don’t teach me something of actual use to my patients, but rather just try to sell me the “latest and greatest” product out, yawn.

The practitioners I know who continually look for “the latest thing out” still use good old Zinc, Vitamin C and B Vitamins. They still recommend Echinacea and Golden Seal as well. But aren’t these herbs and vitamins a little “old hat” too? We still recommend them because we know they work, just like they did fifty years ago. Besides, their patients don’t really change much either; they still like beer, chocolate and take antibiotics – just like they did fifty years ago. Their habits, diets and lifestyles are much the same; the causative factors for yeast infections haven’t really changed much either. And in my opinion, the most effective candida treatment protocol is still the one that uses what has proven to work in the past, along with an excellent understanding of human nature and the actual causative effects of candida.

So why do we continually need to look for the “latest and greatest thing” when it comes to yeast infection supplements? Maybe as practitioners it’s because we are more focused on trying to make a buck out of products instead of actually spending time with our patients and instructing them on the right ways to live, no profits there, the medical profession worked that one out many years ago. As cynical as it may sound, there is little profit in getting people well, but plenty of profit in managing their sickness with drugs or dietary supplements.

Dietary supplement companies are focused on their bottom line, profits, not on patient outcomes, and their customers (practitioners) needs to always bear this point in mind. There is nothing wrong with taking a dietary supplement to recover from a yeast infection, but there comes a time when you won’t need these products anymore because they have served their purpose. And let me tell you, the latest and greatest won’t necessarily get you there any faster. Expect to pay more too.

Many folks with major yeast infections just like me back in the 80’s and 90’s recovered from candida without the help of all these “amazing” candida formulations that seem to come out each year. I’m interested in herbs and dietary supplements with a solid track record, products that have proven themselves over many decades of use, used by many tens of thousands of yeast infection sufferers, and that’s why I still recommend supplements like caprylic acid and GSE, just like Vitamin C and Golden seal. Now, let’s take a closer look at two great candida inhibitors, caprylic and undecylenic acid.

Caprylic Acid Is Tasteless But Undecylenic Acid Is Certainly Not

Unlike undecylenic acid, a monounsaturated fatty acid, a big plus is that MCTs are known for not having any taste, scent or color whatsoever and also aid in weight loss. MCTs are derived from coconut oil, and naturally occur in breast milk, goat’s milk and butterfat. Capsules or gel caps containing undecylenic acid should preferably not be opened, as the average person will certainly not appreciate the taste and odor! Besides, the oil can be quite irritating to the mucous membranes.

Undecylenic Acid Can Be Tricky To Use With Candida

Undecylenic acid is an 11-carbon mono-unsaturated fatty acid that comes from the castor bean. It has proven to be a most effective antifungal agent and is the active ingredient in many over-the-counter antifungal preparations. Just because something is difficult to use doesn’t mean it should be avoided, sometimes you just have to learn a work-around, and I’ve discovered by studying and trial and error that there is an excellent work around with undecylenic acid.

Even though the antifungal activity of undecylenic acid has shown to be more potent than caprylic acid, the problem is that this mono-unsaturated fatty acid is much more sensitive to pH imbalances commonly found in those with candida. Many people with candida have shown to have alkaline pH issues with their small intestine in particular, directly due to the yeast infection and dysbiosis. Many practitioners who recommend different formulations of this fatty acid, whether it is the oil found in gel caps or in a powder (in case of its salts), are not even aware that there are potentially serious delivery issues with undecylenic acid, it is more difficult to use most effectively than caprylic acid with candida. That is, I find it easier to get a good result with caprylic acid than with undecylenic acid but prefer the combined action of both. All you need to do is to add a good quality digestive enzyme along with it or include a little betaine HCL with the supplement itself. Let me explain.

Unlike caprylic acid, studies have shown that undecylenic acid works best in a predominantly acid environment. To ensure that undecylenic acid works best in the small bowel, I have included a small amount of time-release betaine hydrochloride in my Candida Crusher formulation. This ensures that the undecylenic acid will work exactly where you want it to, in the duodenum and ileum, the two parts of the small bowel mostly effected by candida, thus avoiding the release of excessive bicarbonate (an alkaline solution) produced by the pancreas which would potentially render this fatty acid useless. Many people with candida have multiple issues with their digestive system, including their stomach, pancreas, small and large intestine. As the yeast infection subsides, the digestion slowly but surely improves in health. Fatty acids work better if you take between one teaspoon up to one dessertspoon of extra-virgin olive oil daily as well

Is Your Candida Product Sustained-Released And Balanced?

A big downside of nearly all candida products I have trialed is that they are not “sustained release” like my product, CanXida Remove. A major benefit of CanXida Remove is that it delivers the highest concentration of the purest form of caprylic and capric acid in a controlled and sustained released form to both the central and lower intestinal tract out of any comparable product currently available.

CanXida Remove contains (in addition to many other nutrients and herbal medicines) a specially buffered sustained release compound in a very well tolerated form which can be reliably used time and again, even for long periods of time, without inhibiting the growth of normal gut bacteria necessary for optimal health. This is an important feature, because many candida product brands I have trialed over the years were simply too strong and actually added to the problem by inhibiting the reproduction of the friendly bacteria, and others were just too weak to be effective enough to inhibit the reproduction of the several candida strains some folks have when they present to my clinic with a major yeast infection. I’ve learned from many other products that the best product acts on several levels on both the 19 different strains of candida and other yeast species as well as the many different types of bad bacteria and parasites that populate the human digestive system in those with a yeast infection.

Experience has shown me, after analyzing many hundreds of stool tests:

  • The best natural medicines to use when it comes to a yeast infections
  • What proportions of each to use in my formulations.
  • To use standardized forms or herbal medicines to ensure actual potency.
  • To use the highest–grade vitamins & minerals.
  • To ensure slow-release of the formula, ensuring a 2–3 hour delivery.

As you are aware, I specialize in candida treatment and have found caprylic acid to be extremely well tolerated by even the most yeast-sensitive patients and very effective for the inhibition and control of the several strains of candida in both the small and large intestine, but it is important to understand that it is best used in addition to several other key nutrients in order to get a broad-spectrum effect. That way you will not have to rotate several anti-fungal formulations but just stick with the one top quality and proven formula. You save money and complete the job of permanently eradicating your yeast infection in much less time.

A Study Released In PubMed:

“The susceptibility of candida albicans to several fatty acids was tested with a short inactivation time, and ultra-thin sections were studied by transmission electron microscopy (TEM) after treatment with caprylic and capric acid.   The results show that caprylic and capric acids cause the fastest and most effective killing of all three strains of C. albicans tested, leaving the cytoplasm dis-organized and shrunken because of a disrupted or disintegrated plasma membrane”.

I have developed a product called CanXida Remove, it contains caprylic acid as well as undecylenic acid extract (standardized) in addition  to the many other of the best antifungal, antibacterial and anti parasitic natural medicines and is one of the leading candida crushing products on the market.
