Caprylic acid | Strong effect against fungi, bacteria and viruses

Caprylic acid is a medium-chain fatty acid, that is derived from coconut oil, beside capric acid and lauric acid. But some animal and vegetable sources, like butter or palm oil, also contain caprylic acid. Caprylic acid causes the formation of ketones during digestion in the liver. These are an extremely stable source of energy for the human brain, but have the great advantage of not adversely affecting blood sugar levels.

Therefore, caprylic acid or coconut oil is a preferred source of energy for people suffering from Alzheimer’s disease, multiple sclerosis, Parkinson’s disease or diabetes.

But also people who produce too little or too much gastric acid, benefit from the caprylic acid, because it is able to bring the gastric acid to a normal level.

Caprylic Acid against Candida

In naturopathy, caprylic acid is used quite frequently to fight fungi, bacteria, viruses and protozoa. First and foremost, the yeast fungus Candida albicans is treated with caprylic acid. Approximately 75% of the population carry the Candida fungus in themselves. Mostly it is found in the stomach and intestinal tract and / or on the mucous membranes in the mouth and throat.

Normally, the fungus belongs to the normal intestinal flora and forms the immune system with the intestinal bacteria. But if the body is out of balance due to antibiotics, stress, illnesses or excessive sugar consumption, the candida fungus will multiply explosively and lead to a yeast fungus infection – the candidosis.

The caprylic acid is able to change the cell membrane of the Candida fungi in their fluidity and permeability and thus let the cell membrane vanish.

Normally, the human intestinal flora itself is able to produce sufficient amounts of caprylic acid to prevent fungal infection in the intestine. But if the intestinal flora is disturbed, a several-week course of caprylic acid is the tool of choice to protect against fungal infection. Caprylic acid, unlike many other intestinal antifungals, is not made from molds. Because of this, there is zero  risk of allergy, which makes caprylic acid the optimal natural mushroom remedy.

Does caprylic acid have side effects?

If you look at the recommended daily dose of max. 2000mg, no side effects are known. At an intake of significantly more than 5000mg daily, mild nausea and gastrointestinal complaints were reported. However, if the caprylic acid is taken with meals, there should be no problems at all.

But if the intestine is colonized with a high amount of Candida, it maybe comes to the so-called Herxheimer reaction. This is an initial deterioration due to the fact that the yeast fungi in the intestine die in large numbers due to caprylic acid and thus release a considerable amount of toxins and antigens. These cause dizziness, tiredness, a feeling of drowsiness, headaches, insomnia and much more.

With regular use of caprylic acid, this reaction can last from a few days to several weeks and unfortunately, this often is the reason why candida patients break up the treatment prematurely. But in most cases, these symptoms of poisoning clear within a week.

The only positive thing about the Herxheimer reaction is the fact that the caprylic acid works and eliminates the intestinal fungus.

Why I use Caprylic Acid

The Candida Albicans has been my loyal companion since 2008, so I have to fight it again and again. In the beginning, I always used the chemical fungicide Nystatin, but the effect diminishes quickly and the fungi also become resistant to the active ingredient. In addition, I have not been a friend of chemical drugs for a long time and have been looking for natural alternatives.

In addition to grapefruit seed extract, oregano oil, olive leaf extract, pomegranate and lapacho tea, caprylic acid is a very powerful tool to eliminate Candida albicans.

But the most important thing about the entire treatment, is the nutrition. And this is also the reason why the Candida fungus has appeared again and again. Over the years, I had some weak moments again and again, where I ended up with nibbling some chocolate.

This has repeatedly led to relapses. But currently it seems to work very well. To avoid resistance, I take a  fungizid only for three weeks and then switch to another one. Currently I use caprylic acid for 3 weeks and then grapefruit seed extract again for 3 weeks.
