Is Caprylic Acid Good for Candida?

My Name is Eric Bakker (N.D.) & I'm Here to Teach You the Candida Cleanse I've Successfully Used On Over 60,000 Patients At My New Zealand Clinic

Is Caprylic Acid Good for Candida?

There’s lots of information online on different Candida websites about caprylic acid and how to use it. 

A lot of this information is put together by people who’ve never seen any patients, but there’s also plenty of information by people like me who do see patients.

Caprylic acid first became popular in 1983 when Dr. William Crook published his now famous book — The Yeast Connection. Dr. Crook believed caprylic acid to be the #1 most effective effective anti-candida supplement of the 80’s.  

And as you’ll soon learn, it's still just as effective today.

What is caprylic acid and where does it come from?

As you’ve probably heard, caprylic acid is a monounsaturated fatty acid (one of the healthy fats) found primarily in coconut. 

Coconut actually contains 3 of these acids, all of which are medium chain fatty acids (also known as MCT). If you’ve heard of MCT oil or MCT fats before, that’s what caprylic acid is. The other 2 MCT fats found in coconut are capric acid and lauric acid. 

All 3 of these fatty acids have been shown to be anti-fungal and kill yeast & bad bacteria. 

So why does everyone focus on caprylic acid you ask? Simple. Because caprylic acid is the most effective of the 3. 

This is not new information. Organic fatty acids like MCTs have been used literally since 2,800 B.C. (meaning 4,800 years ago) for their anti-fungal and anti-microbial purposes. That’s why soap was traditionally made from fats and why we use still use them today to clean things.

But it was only in 1961 that scientists in Japan discovered these MCT fats had other uses other than cleaning or washing our hands. That is, you can take them orally to kill off yeast & bad bacteria in the gut.

Can caprylic acid really kill Candida?

The answer is yes. Caprylic acid is HIGHLY effective at killing Candida.

Here’s what the Japanese study published in 1961 that I mentioned above had to say about it:

Caprylic acid exhibits the most remarkable fungistatic and fungicidal properties of all the normal saturated fatty acids with even numbered carbon atoms studied. The fungicidal activity of caprylic acid depends upon the concentration of the acid, the period of contact and the pH of the media.”

Pretty impressive, don’t you think? 

Notice the last sentence about concentration and pH being determining factors. This is very important and we’re going to get back to this in a minute when we talk about supplements & how to use caprylic acid for maximum effect. 

I’ve personally found caprylic acid to be extremely well tolerated (meaning no side effects or strong reactions) by even the most yeast-sensitive patients. 

How does caprylic acid work?

Caprylic acid stops the growth of Candida by weakening its cell membrane (the outer edge of the yeast cell).

So, I want you to think of a yeast cell like a rubber balloon filled with water. Now imagine what would happen if you poured something like acetone (the main ingredient in nail polish remover) which dissolves rubber on this poor little water balloon. 

The rubber would turn to goo and all the water would spill out. That’s what caprylic acid does to Candida.  

Once it gets weak enough, the yeast cell ruptures and all the cytoplasm (the liquid inside the cell) spills out. This allows your immune system to attack it and kill Candida. 

Here’s how a 2001 study you can find on PubMed describes it:

The results show that caprylic acid and capric acids cause the fastest and more effective killing of all three strains of C. Albicans tested, leaving the cytoplasm disorganized and shrunken because of a disrupted or disintegrated plasma membrane.”

I’ve personally seen caprylic acid stop the growth of several Candida strains in both the small and large intestine.

However, it is important to understand that while caprylic acid effective, it is best used in addition to several other anti-fungals that amplify its effect (which is the topic of the next section).

Why you should combine caprylic acid with something called undecenoic acid:

Many years ago I used to give caprylic acid alone to Candida patients who came to my naturopathic clinic. 

Then later on just undecenoic acid (also known as undecylenic acid or 10-undecenoic acid, they all refer to the came thing). But then I discovered that when you put these two acids together you get a much stronger or amplified effect.

So, undecenoic acid is a fatty acid that comes from castor bean. It’s a little more potent than caprylic acid but prefers a slightly more acidic environment to work. 

I’m not going to go super in-depth into undecnoic acid here. You can read my other article on it later

My naturopathic clinic has tried well over 100 Candida killing products in different combinations and I’ve consistently found undecenoic acid and caprylic acid to work better together. They kill off a wider range of Candida species when you combine them vs if you take them alone.

How to make caprylic acid & undecenoic acid even more effective:
I taught you that if you take caprylic acid with undecenoic acid (which comes from castor beans) you get a stronger kill effect on a wider range of Candida species.

But you can amplify caprylic acid EVEN MORE if you combine these two acids with something called Betaine HCL.  

Betaine HCL is another ingredient that works extremely well with a caprylic / undecenoic acid combination. Many people with Candida have pH issues in their small intestine which would inhibit the effect of undecenoic acid if betaine wasn't present.

Betaine helps because it lowers the pH a little in the environments where these two acids work together. 

Betaine also ensures undecenoic acid works exactly where it needs to, which is the duodenum and ileum (the two parts of the small bowel most effected by Candida). This is a very strategic combination you won't find in many supplements. 

Think of this caprylic acid / undecenoic acid / betaine combination as a shotgun approach vs a rifle approach. You end up with a broad spectrum effect that doesn’t just knock out Candida Albicans, but 19 other Candida strains as well. 

It also targets any bad bacteria that have teamed up with Candida & overgrown due to the toxic gut environment Candida creates for itself.

This is very important because in my experience doing thousands of comprehensive stool tests on patients — the majority of people who have Candida have also got dsybiotic (bad) bacteria in there as well that needs cleaning up.

That’s why I tell patients they shouldn’t take caprylic acid alone & why I’m telling the same thing to you. 

So make sure whatever formula you take has all three of these at the very least. You’re really missing the boat if you’re not. Keep reading and I’ll give you some supplement recommendations at the bottom of this page.

Can Candida become resistant to caprylic acid?

Resistance doesn’t occur with natural anti-fungals like caprylic acid or the other ingredients I mentioned.

That only happens with drugs.


This has been confirmed many times with studies done on things like grapefruit seed extract, caprylic acid, undecenoic acid, clove, and other natural anti-fungals. It just doesn’t happen.

It happens with pharmaceutical drugs because they are synthetic. They’re only made up of one thing. They’ve got one ultra refined chemical compound with a very narrow band of action. Once Candida develops a resistance to this action, the pharmaceutical drug is done. 

Remember, Candida is very adaptive. If you only hit it with one action it will soon work out how to fool this action. And you know what happens next. The drug no longer works and the yeast comes back. And then you go back to the doctor who puts you on a a new drug and the cycle repeats again.

Natural anti-fungals are different. 

Caprylic acid and undecenoic doesn’t just contain one thing. They’ve got many different natural chemicals and compounds in there that make it up. That’s why I call it a shotgun effect. They attack Candida from many different angles so the yeast gets overwhelmed. It doesn’t know what hit it and it can’t fight back.

This is why I tell patients to get a natural broad spectrum formula and not go the pharmaceutical route. This way you don’t have to rotate several anti-fungal formulas and can just stick to one top quality proven formula long term. 

And this formula just continues to work because yeast can’t develop a resistance to it.

Can you get caprylic acid just from eating coconut?

If you’re consuming coconut oil, coconut cream, or coconut milk, you’re getting caprylic acid into your diet.

But coconut doesn’t contain undecenoic acid, or betaine HCL. It targets Candida Albicans but it doesn’t do a great job against some of the other Candida strains you may have or any of the bad bacteria I mentioned previously. 

So yes, I encourage you to eat coconut oil and drink coconut milk. But take it alongside other anti-fungals and anti-bacterials. That’s how you truly knock out Candida. 

Which form of caprylic acid is best — gel capsules, tablets, liquid or something else?

It’s best to take caprylic acid in tablet form that has undecenoic acid powder and betaine HCL mixed in with it.

I’m not a fan of these small gel capsules with caprylic or undecenoic acid in them. I don’t find them nearly as effective as the dried powder form of these acids.

When you select a tablet, make sure that it’s sustained release. Sustained release means when you swallow this tablet, your digestive system doesn’t get access to everything immediately. 

But over a period of several hours it slowly breaks down in the gut. 

That way it targets all parts of your GI track. It cleanses all the yeast and bad bacteria right from your mouth and keeps working all the way through the colon and “back passage.”

Now, likely the supplements you were taking before were not sustained release. They weren’t put together by someone with decades of experience treating your specific health problem. They were likely put together by a company that’s got a 1000 other products and they pay lip service to making an anti-fungal or anti-bacterial formula.


Or they’ve just put out a caprylic acid product or an oregano product. 

And that is expensive.

Why? Let’s say you’ve trying to hunt down products to clean up your gut. You do a stool test and it says you’ve got a high count of Klebsiella (a type of bad bacteria) in there along with the Candida. 

You may have 2 or 3 issues in your gut that need fixing. You’re then likely to look at several separate products. And that’s going to cost you. That’s why a broad spectrum formula that has all of these ingredients in a sustained release form is the way to go.

How to choose the most effective caprylic acid supplement:

After treating many Candida patients over the past 30 years or more, 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.

Some doctors say you need to get your anti-fungals naturally from whole foods and not rely on supplements. But in fact that’s what my patients were doing for years. They were going to health food stores. They were buying organic foods.

And it wasn’t working.

They were buying a little of caprylic acid, or a little bit of betaine or a bottle of grapefruit seed extract. But no one had ever put a highly effective product together that targets a wide range of gut pathogens at the same time. 

That's why I got disappointed with the junk that was available in grocery stores. It’s different for you because if you have a problem and you buy a product, it’s either going to work or it’s not.

I treated thousands of people like you, so I got feedback all the time and felt responsible if something I told a patient to take ended up not getting them the results they wanted.

So in 2013 I set out to create my own formulations to MY standards. The first product I created was called CanXida RemoveCanXida Remove is an advanced 12 ingredient anti-fungal, anti-bacterial and anti-parasite formula based on nearly 33 years of research working with 60,000 gut disorder patients at my New Zealand clinic or via Skype. 

It contains high-grade caprylic acid & in sustained release form.

I’m not going to go too in-depth into here because this page isn’t about selling supplements. You can learn more about CanXida by watching the video below or by visiting 

Whatever supplement you go with, make sure it’s high quality. Go with a broad spectrum formula made by someone with experience. Pick a supplement that doesn’t have just caprylic acid, undecenoic acid and betaine HCL in there but also things like grapefruit seed extract, standardized garlic, neen, clove, and oregano.

Try to go with a formula that uses standardized ingredients

Standardization means that each time you take this supplement, you're getting a consistent therapeutic dose. It doesn't vary in potency from batch to batch as is often the case in non-standardized supplements. It's a bit like how pharmaceuticals are made.

You get the same strong therapeutic dose every time you take it.

Some practitioners tell me that caprylic acid, grapefruit seed extract and the other ingredients I use are “old hat” and that it’s time to “upgrade.” These opinions come from dietary supplement companies who convince their customers (the healthcare professionals) that the most effective products are the latest ones they release every year.

I'm not a fan of this approach.
