12 Science-Backed Benefits Of Caprylic Acid & How To Use It
Harness natural MCT support for balanced digestion, immunity strength, and clearer skin.
Caprylic acid, a medium-chain fatty acid naturally found in coconut oil, palm oil, and breast milk, has garnered significant scientific attention for its potent antimicrobial, antifungal, and anti-inflammatory effects. Widely used as a supplement for digestive health and immunity, caprylic acid may help manage conditions from candida overgrowth to skin issues, making it one of the most versatile natural compounds available.
What Is Caprylic Acid?
Caprylic acid (also known as octanoic acid) is an eight-carbon, saturated fatty acid classified among medium-chain triglycerides (MCTs). It occurs naturally in coconut oil, palm kernel oil, certain dairy products, and human breast milk. Due to its unique structure, it is quickly absorbed and metabolized for energy in the body.
- Common source: Coconut oil, comprising about 7–15% caprylic acid by content.
- Supplements: Available in pure caprylic acid and as part of MCT oil blends.
Top 12 Benefits Of Caprylic Acid
1. Powerful Antifungal Properties: Fights Candida & Yeast
Caprylic acid is highly effective at battling fungal overgrowth, particularly Candida albicans. It acts by disrupting the cell membranes of problematic yeast and fungi, causing their elimination.
- Reduces Candida symptoms: bloating, fatigue, skin issues, vaginal yeast infections.
- Inhibits biofilm formation and prevents the transformation of yeast from benign to invasive forms.
- Proven to work synergistically with other antifungals for enhanced efficacy.
2. Antibacterial Activity
Caprylic acid helps combat various pathogenic bacteria, supporting a healthy balance of gut flora and suppressing harmful microbes such as E. coli, Salmonella, and Cronobacter.
- Suppresses intestinal bacterial infections.
- Supports the proliferation of beneficial gut bacteria, boosting immune function.
3. Supports Digestive & Gut Health
Caprylic acid reduces inflammation in the gastrointestinal tract and promotes the integrity of the gut barrier, potentially protecting against “leaky gut” and supporting those with absorption difficulties.
- Helps repair and protect the intestinal barrier under stress.
- Enhances nutrient absorption as a rapidly absorbed MCT.
- Reduces gut inflammation and improves overall digestive health.
4. May Help With Weight Loss & Energy Metabolism
As an MCT, caprylic acid can boost energy, curb appetite, and aid weight management. It is preferentially used by the liver for rapid energy production.
- Increases energy expenditure and thermogenesis.
- Suppresses appetite by influencing hunger hormones (ghrelin and leptin).
- Helps the body use fat for fuel, supporting fat loss goals.
5. Helps Treat Yeast Infections
Caprylic acid’s antifungal action extends to vaginal yeast infections, oral thrush, and nail fungus. It works by killing or inhibiting Candida albicans growth both internally (supplements) and externally (topical application).
What others are reading
- May be used as a supplement or in coconut oil-based topical formulas for targeted treatment.
- Oil pulling with coconut oil may help oral thrush.
6. May Lower Inflammation And Support Immunity
Caprylic acid can reduce inflammation signals in intestinal cells, supporting healthy immune function and lowering overall inflammation.
- Acts as a natural modulator of immune response, helping to balance overactive inflammation.
- Aids production of healthy gut flora, impacting immune strength.
7. Promotes Skin Health & Fights Acne
Thanks to its antibacterial, antifungal, and anti-inflammatory effects, caprylic acid can help manage skin conditions.
- Reduces acne-causing bacteria and yeast when applied topically or consumed.
- May soothe inflamed, itchy, or infected skin and aid in the healing of wounds.
- Frequently used in products for eczema, psoriasis, seborrheic dermatitis, and other chronic skin issues.
8. May Lower The Risk Of Antibiotic Resistance
Regular use of natural antibacterial compounds like caprylic acid for minor infections may help reduce unnecessary use of antibiotics, thereby lowering the risk of antibiotic-resistant bacteria developing.
9. Potential Support For Cholesterol & Heart Health
Some evidence suggests MCTs like caprylic acid may help promote healthy cholesterol levels and cardiovascular function.
- May help maintain a healthy balance of LDL and HDL cholesterol.
10. Aids In Nutritional Support For Individuals With Malabsorption
Because medium-chain triglycerides are digested and absorbed more easily than long-chain fats, they are often recommended for patients with fat absorption issues (e.g., digestive disorders, short bowel syndrome).
11. Assists In Detoxification
Caprylic acid’s antimicrobial and antifungal activity aids in detoxifying the digestive tract, especially during candida die-off.
- May support protocols aimed at cleansing yeast and toxins from the body.
12. May Protect Against Certain Viral & Parasitic Infections
Emerging evidence suggests caprylic acid may reduce the effects of some viral and parasitic organisms
- Found to reduce symptoms in some viral and fungal infections in preliminary studies.
Caprylic Acid In Food Sources
Natural sources of caprylic acid include:
- Coconut oil (primary natural source)
- Palm kernel oil
- Dairy products (in small amounts, e.g., butter, goat’s milk, cow’s milk)
- Human breast milk
| Source | % Caprylic Acid (C8) |
|---|---|
| Coconut Oil | ~7–15% |
| Palm Kernel Oil | ~4–8% |
| Butter (Cow’s Milk) | ~1–2% |
| Goat’s Milk | Trace amounts |
How To Take Caprylic Acid
Caprylic acid is available as a food ingredient, capsule, softgel, liquid MCT oil, or as part of coconut oil. Standard practices for use include:
- For digestive/Candida support: 500–1,000 mg capsules, 1–2 times daily, gradually increasing as tolerated.
- As dietary MCT oil: 1–2 tablespoons daily added to smoothies, coffee, or food.
- Topical (for skin): Diluted coconut oil or caprylic acid-containing creams (patch test first).
Note: It’s best to consult a healthcare professional before starting, especially if you have underlying conditions, are pregnant, breastfeeding, or are taking other medicines.
Possible Side Effects & Precautions
- Generally safe at recommended intakes for most healthy people.
- Potential mild side effects: digestive upset, diarrhea, nausea, bloating, or cramping (more common with rapid introduction at high doses).
- Rarely, allergic reactions may occur (test topical products on a small area first).
- May interact with medications for high blood pressure and other lipid-altering drugs—medical supervision advised.
Who Should Avoid Caprylic Acid?
- People with allergies to coconut, palm, or dairy (depending on source).
- Pregnant or breastfeeding women (unless approved by a healthcare provider).
- Children (unless used as prescribed or in food amounts).
- Individuals with liver conditions should use with medical guidance, as MCTs are processed by the liver.
FAQ: Caprylic Acid
Q: Can caprylic acid treat Candida overgrowth?
A: Yes, caprylic acid has proven antifungal activity that disrupts Candida albicans cell walls, aiding candida management and die-off. It is often recommended alongside diet changes and probiotics for optimal benefit.
Q: Is caprylic acid safe for long-term use?
A: Most studies suggest caprylic acid is safe when taken in recommended amounts. For long-term or high-dose use, especially for specific conditions, consult a healthcare professional.
Q: How quickly does caprylic acid work for yeast or bacterial infections?
A: The timeline varies, but some improvements may appear within days to weeks for mild infections. Please note that severe or chronic infections require professional supervision.
Q: What is the difference between caprylic acid and other MCTs?
A: Caprylic acid (C8) is one of the shortest and most potent MCTs. It is more rapidly absorbed for energy and has stronger antimicrobial action compared to capric acid (C10) and lauric acid (C12).
Q: Can I get enough caprylic acid from food alone?
A: Regular consumption of coconut oil, palm kernel oil, or MCT oil can provide dietary amounts, but supplements may be needed for therapeutic benefit. Dosage should be guided by individual needs and professional advice.
