Who should not take caprylic acid? A guide to contraindications and precautions

4 min read

While generally safe for many, caprylic acid supplements are not recommended for everyone, particularly individuals with certain genetic conditions or those who are pregnant. Understanding who should not take caprylic acid is essential for preventing adverse effects and ensuring your health and safety.

Quick Summary

Caprylic acid supplements should be avoided by people with MCAD deficiency, those who are pregnant or breastfeeding, and individuals with liver disease or hypotension. Caution is also advised for those taking blood thinners, NSAIDs, or antihypertensive drugs due to potential interactions.

Key Points

  • MCAD Deficiency: Individuals with this rare genetic disorder must avoid caprylic acid, as their bodies cannot metabolize it, which can lead to serious complications including coma.

  • Pregnancy and Breastfeeding: The safety of high-dose caprylic acid is not established for pregnant or breastfeeding women, and supplementation should be avoided during these periods.

  • Drug Interactions: Caprylic acid can interfere with common medications, including blood thinners (warfarin), NSAIDs, and antihypertensive drugs, increasing the risk of adverse effects.

  • Liver and Blood Pressure Issues: Those with liver disease or pre-existing low blood pressure (hypotension) should use extreme caution and medical supervision, as caprylic acid can worsen these conditions.

  • Digestive Sensitivity: Individuals with sensitive gastrointestinal systems, including inflammatory bowel conditions, may experience worsened symptoms like bloating and cramping due to the supplement's effects on gut flora.

  • Start Low and Monitor: To minimize common side effects like nausea and diarrhea, a low dosage should be used when starting, with gradual increases as tolerated.

Primary contraindications for caprylic acid

For specific health conditions, taking caprylic acid is a definite contraindication due to significant health risks. It is crucial to be aware of these scenarios to avoid severe complications.

Medium-Chain Acyl-CoA Dehydrogenase (MCAD) deficiency

This is a genetic disorder that affects the body's ability to break down medium-chain fatty acids, including caprylic acid. For individuals with MCAD deficiency, ingesting caprylic acid can be extremely dangerous. Without the necessary enzymes to metabolize the fatty acid, it can build up in the bloodstream, increasing the risk of serious side effects and even leading to comas. For anyone with this diagnosed condition, caprylic acid supplementation is strictly off-limits.

Pregnancy and breastfeeding

There is a significant lack of reliable research on the safety of high-dose caprylic acid supplementation during pregnancy and while breastfeeding. As a result, healthcare professionals strongly advise against its use during these sensitive periods to avoid unnecessary risks to both mother and child. Some evidence suggests that supplementation during pregnancy can cause or aggravate digestive problems like nausea. Until more is known, staying on the safe side by avoiding supplementary amounts is the recommended course of action.

Health conditions requiring extreme caution

In addition to strict contraindications, several medical conditions necessitate a discussion with a healthcare provider before considering caprylic acid, as it may worsen existing issues.

  • Liver disease: Caprylic acid is metabolized by the liver. For those with compromised liver function, the body may not be able to process the substance effectively, potentially causing caprylic acid levels to rise. While research is ongoing, those with liver conditions should proceed with extreme caution and medical supervision.
  • Low blood pressure (hypotension): Caprylic acid has been shown to potentially lower blood pressure. For individuals already prone to low blood pressure, supplementation could cause a dangerous drop in blood pressure, leading to dizziness, weakness, or fainting.
  • Inflammatory bowel conditions (IBS/IBD): As a treatment often used for balancing gut flora, caprylic acid can cause a 'die-off' effect of Candida yeast. For those with sensitive or inflamed guts due to conditions like IBS or IBD, this die-off can trigger or worsen symptoms, including bloating, cramping, and digestive upset. Starting with a very low dose and monitoring symptoms is essential.
  • Osteoporosis: Some limited research suggests caprylic acid might worsen problems related to bone density. Given the uncertainty, individuals with weak or brittle bones should use caution until more definitive research is available.
  • Kidney problems: Some information suggests caprylic acid may not be recommended for individuals prone to kidney stones or with existing kidney problems. The metabolism of fatty acids can be complex, and caution is warranted.

Drug interactions with caprylic acid

Caprylic acid can interact with certain medications, primarily by competing for binding sites on albumin, a protein in the blood. This can increase the amount of active medication in the body, magnifying its effects and potential side effects.

  • Blood thinners (e.g., warfarin): Caprylic acid can displace warfarin from albumin, increasing its potency and raising the risk of bruising and bleeding. Anyone on blood thinners must monitor their blood levels closely if supplementing with caprylic acid, and a dose adjustment may be necessary.
  • Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Similar to warfarin, caprylic acid can displace NSAIDs like ibuprofen or naproxen from albumin, increasing their active concentration in the blood. This can lead to more pronounced effects and an increased risk of side effects from the NSAID medication.
  • Antihypertensive drugs: Because caprylic acid can lower blood pressure on its own, combining it with medications for high blood pressure can cause an excessive drop. This can be dangerous and requires close monitoring by a healthcare provider.

Comparison of caprylic acid risks

Patient Group Primary Concern Mechanism of Risk Medical Guidance Required? Level of Risk
MCAD Deficiency Metabolic failure leading to buildup of fatty acids. Inability to break down caprylic acid due to missing enzymes. Yes, avoid completely. High
Pregnant/Breastfeeding Unknown safety, potential digestive issues. Lack of research, potential for adverse effects on mother and child. Yes, avoid high-dose supplements. Moderate to High
Liver Disease Impaired metabolism and potential for accumulation. The liver is responsible for breaking down caprylic acid. Yes, use with caution and monitor. Moderate
Taking Warfarin Increased bleeding risk due to drug interaction. Caprylic acid displaces warfarin from binding proteins. Yes, close monitoring and dose adjustment. Moderate
Taking NSAIDs Increased effects and side effects of the NSAID. Displaces NSAIDs from binding proteins, increasing active concentration. Yes, use with caution. Moderate
Hypotension (Low BP) Blood pressure may drop too low. The supplement can have a blood pressure-lowering effect. Yes, close monitoring. Moderate
Inflammatory Bowel Disease Exacerbated symptoms due to "die-off" reaction. Changes to gut microbiome can cause sensitivity. Yes, proceed slowly and cautiously. Low to Moderate

General precautions and side effects

Even for those without underlying health conditions, caution is necessary when starting caprylic acid supplementation. High doses or rapid introduction can cause gastrointestinal upset, including nausea, bloating, and diarrhea. It is widely recommended to start with a low dose and increase it gradually to allow the body to adjust and minimize these potential side effects.

Finally, for parents considering caprylic acid for children, it is important to remember that safety data for children is limited. Supplements should be kept out of reach of children, and use should only be considered under the guidance of a qualified healthcare provider.

Conclusion

While caprylic acid is a popular natural supplement, especially for gut health, it is far from harmless for everyone. Individuals with genetic disorders like MCAD deficiency, as well as pregnant and breastfeeding women, should avoid it entirely. Furthermore, those with pre-existing conditions such as liver disease, hypotension, or inflammatory bowel disease, as well as those on specific medications like warfarin, NSAIDs, or blood pressure drugs, must consult a healthcare provider to assess the risks. Awareness of who should not take caprylic acid is the most important step in safe supplementation.
