The Best Caprylic Acid: Our Picks

Advice: Questions you should ask yourself before buying caprylic acid

What is caprylic acid?

Caprylic acid is also known as octanoic acid and belongs to the group of carboxylic acids. The name of this saturated fatty acid is derived from the Latin “capra” or “caper”, which stands for goat.

The substance is mainly extracted from coconut oil. However, it is also found in many plant and animal foods.

What are the effects of caprylic acid?

Caprylic acid has a long list of functions on the human body. As already mentioned, the substance is a well-known topic in naturopathy.

During digestion in the liver, for example, the substance ensures the formation of ketones, which are an extremely important source of energy for the human brain. In addition, they have the advantage of not influencing the blood sugar level too negatively during the process.

People with an unusually high or low gastric acid production can benefit from caprylic acid, as it is able to bring the gastric acid to an acceptable level.

The substance belongs to those fatty acids in the body from which energy can be obtained particularly quickly and reserves can be built up. Furthermore, it is known for its excellent effect against bacteria, viruses and fungi.

Did you know that caprylic acid treats acne and skin infections?

Due to its antibacterial and antimicrobial properties, the acid can treat acne and other skin problems. In addition, it kills harmful bacteria on the skin that can cause infections or inflammation.

What positive effects are attributed to caprylic acid?

Caprylic acid has a number of positive effects on the body in addition to those mentioned above. For example, the treatment with caprylic acid of certain yeast fungi is known. These are also known as “Candida Albicans”. Almost 75 % of the population is affected by it.

As a rule, these fungi are found in the stomach and intestinal tract, but also on the mucous membranes in the throat and mouth. In a real sense, the fungus contributes to the human immune system.

Negative factors such as high stress levels, diseases or high sugar consumption can cause the fungi to multiply rapidly.

In such cases, we therefore speak of a yeast infection, candidiasis to be precise. In many cases, the body is naturally able to produce a sufficient amount of caprylic acid so that the infection can be fought.

In the case of a disturbance of the intestinal flora, on the other hand, a cure of several weeks is recommended, in which caprylic acid is taken at regular intervals.

Another aspect is the positive effect on the body and the brain. As an energy supplier, brain performance can be increased, while physical performance is also boosted by a kind of boost.

Did you know that caprylic acid reduces the risk of antibiotic resistance?

According to studies, caprylic acid was able to reduce five different types of dangerous pathogens. The acid works similarly to antibiotics, but without the risk of bacterial mutations.

Unlike a high-carbohydrate diet, the formation of ketones does not raise insulin levels.

The advantage of this is that typical performance lows can be avoided after a certain time after ingestion. In addition, the substance has a protective effect on the neurons, so that symptoms of Alzheimer’s and dementia can be effectively counteracted.

What are the side effects of caprylic acid?

Caprylic acid usually has no side effects at a maximum daily dose of 2g. However, at extremely high doses beyond 5g per day, there are numerous reports of mild nausea and stomach or intestinal discomfort.

In addition, in the case of a large amount of candida in the stomach, a so-called Herxheimer reaction can occur. This is a kind of initial aggravation. The reason for this is the death of a large number of yeast fungi in the intestine, which can be caused by the caprylic acid.

The result is a release of considerable amounts of toxins and antigens. Typical symptoms of this are dizziness, fatigue, a feeling of drowsiness, headaches and insomnia.

Interestingly, if taken regularly, this reaction diminishes considerably after a few days in most cases.

However, the Herxheimer reaction also has a noticeable advantage; the successful action of caprylic acid eliminates the intestinal fungi.

What is the appropriate dosage of caprylic acid?

The dosage is 1000 to 2000 milligrams, which should be spread over the day. A lower dose is not recommended, as otherwise the effect of the substance cannot spread sufficiently.

The therapy itself lasts about three to four months, depending on the clinical picture. In rare cases, however, the treatment can last one to two years. The reason for this is the Candida fungus, which in unfavourable cases hides in the folds of the intestinal wall.

In addition, a gradual increase of the dose is recommended. Therefore, a small dose should be taken at the beginning. As with many other substances, the body needs a certain amount of time to get used to the substance. Therefore, a higher dosage is advisable in the further course.

In addition, the Herxheimer reaction as a possible side effect can thus be prevented.

Decision: What types of caprylic acid are there and which is the right one for you?

Basically, you can distinguish between three different types of caprylic acid:

  • Oil
  • Capsules
  • Tablets

In the following, we explain the different types and their respective advantages and disadvantages. In this way, we want to help you find the most suitable caprylic acid product for you.

What is caprylic acid oil and what are the advantages and disadvantages?

Caprylic acid oil has an extremely high purity, which can be over 99%. The oil can also be added to food and drinks. Furthermore, there are products on the market that offer the oil in a tasteless and odourless form.

  • Tasteless and odourless
  • Can be used in combination with food and beverages
  • Extremely high purity
  • Large variety of offers
  • Individual dosage possible
  • Unsuitable for on the go

What are caprylic acid capsules and what are the advantages and disadvantages?

The caprylic acid is inside the capsule shell, which dissolves in the stomach after ingestion. The active ingredient contained in the capsule then unfolds.

  • Neutral taste
  • High purity
  • Effect is delayed
  • May not be suitable for vegetarians/vegans
  • Individual dosage possible to a limited extent

The disadvantage is that the effect is delayed. In addition, the capsule shell is made of gelatine, so vegetarians and vegans should check its origin before buying.

What are caprylic acid tablets and what are the advantages and disadvantages?

Caprylic acid tablets are usually taken orally, which is why they are also suitable for on the go. They can also be dissolved in a drink and then consumed. By taking them directly, the effect can develop quickly.

  • Suitable for on the go
  • easy to take
  • Individual dosage only possible to a limited extent

Buying criteria: Use these factors to compare and evaluate caprylic acid

In the following we will show you which criteria you can use to compare and evaluate caprylic acid. This will make it easier for you to get an overview and decide on a suitable and effective product.

In summary, these are the following criteria:

  • Dose
  • Purity
  • Dosage form

In the following, you can read about the respective criteria and find out why it makes sense for you to purchase a product based on the criteria or not.


The dose provides information on how strong the effect will ultimately be. In the case of an intensive fungal infection, a high dosage is recommended. However, it is also advisable to increase the dosage gradually if you are new to the product.

Products that are accompanied by a number of other substances are usually characterised by a lower dose.

For an optimal supply of synergistic nutrients, a basic supplement of a good multi and vitamin C is recommended. In addition, the therapy can also be supported with garlic extract.



A higher purity is accompanied by a higher effect. Oils in particular have a high purity. High-quality products often have a purity value of 99%. Tablets, on the other hand, are often characterised by a lower purity. A high purity also has other advantages.

For example, it reduces the risk of harmful by-products being produced during the manufacturing process. For this reason, it can be said that regardless of the intended use, a product with the highest possible purity is advisable.

Dosage form

For people who want to take caprylic acid on the go, tablets are the best choice. These can be taken directly by oral administration without complications. Alternatively, they can also be dissolved in a drink, which is then drunk.

However, if you want to do without the taste, capsules are the best solution. These contain caprylic acid in the form of oil, which is found inside the capsule shell. However, a delayed effect is to be expected, as the substance is only distributed in the body in the stomach area.

The oil, on the other hand, can be taken directly, so that the effect does not only unfold after a certain time. In addition, caprylic acid oil can be used in a variety of ways. Besides direct ingestion, the oil can also be added to a drink.

Alternatively, the oil can also be used in food. However, the temperature must not exceed 120 degrees Celsius. There are also products in which the oil has no taste.

This has the advantage that the flavour of the food is not changed and that the positive effect of the substance can be profited from.

Facts worth knowing about caprylic acid

Production of caprylic acid – What alternatives are there?

In addition to the conventional extraction of caprylic acid from coconuts, researchers now offer an alternative.

The reason for this is that the production of coconut oil mainly takes place in Southeast Asia. The production for chemical purposes is often in direct competition with the use of coconut oil as food.

Yet the oil is an important component of the diet of the low-income rural population in Southeast Asia.

In addition, large areas are needed to cultivate the palms, for which correspondingly large areas of rainforest are usually cleared. For this reason, the production of caprylic acid can affect the standard of living of the population in Southeast Asia and also damage nature.

In addition, the cultivation of coconut palms requires the use of large amounts of pesticides. Castor oil, on the other hand, is usually cultivated sustainably in South America. Moreover, the substance has been used by the chemical industry as a raw material for polymer production since the 1940s.

In this production process, n-heptanol is inevitably produced as a by-product. With the help of carbonylation, n-heptanol can be converted into n-octanoic acid, i.e. caprylic acid. A process is therefore to be developed in the future for this purpose.

The German Federal Ministry of Research and Education has made a sum of over 57,000 euros available for this project.

The following table compares the two substances and their advantages and disadvantages:
