HelloPharmacist Scorecard of MCT/Butyrate Liquid by Douglas Laboratories

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • “Medium-Chain Triglycerides” is listed as a grouped ingredient — the label gives one combined amount (8.60 Gram(s)) without saying how much of each component you get.
  • “SunButyrate Butyrate Triglyceride” is listed as a grouped ingredient — the label gives one combined amount (5 Gram(s)) without saying how much of each component you get.

This liquid contains 2 active ingredients: caprylic acid and butyric acid. Caprylic acid is a medium-chain fat found naturally in coconut oil and some dairy products; butyric acid is a short-chain fat produced by gut bacteria.

Together they're meant to support gut and metabolic health. The product also contains inactive ingredients — natural vanilla flavor, lemon oil, mixed tocopherols (a form of vitamin E), and rosemary extract — which serve as flavoring and preservation.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Caprylic Acid product and its label doesn't state a use — see Caprylic Acid's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold doesn't establish that caprylic acid works reliably for epilepsy or essential tremor — the data rates both as insufficient. We have no effectiveness information on file for butyric acid.

The evidence, ingredient by ingredient Caprylic Acid

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Caprylic acid is generally well tolerated in the short term when taken by mouth. The most common side effects are mild stomach discomfort and a change in taste.

A small number of people have reported dizziness, headache, or fatigue. That said, caprylic acid is recognized as safe in food, but supplement doses are less well studied — avoid taking this product unless your doctor approves.

If you're breastfeeding, caprylic acid does occur naturally in breast milk, but the safety of concentrated supplement doses is unknown, so use caution and talk with your doctor or pharmacist first.

Side effects, ingredient by ingredient Caprylic Acid

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Caprylic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 262 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check before combining this product with blood thinners like warfarin (Coumadin) — caprylic acid may raise warfarin levels and bleeding risk. Also double-check blood pressure medications and NSAIDs (ibuprofen, naproxen, etc.), which may have their blood levels increased or effects amplified.

We could not check butyric acid for drug interactions.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is for anyone exploring caprylic and butyric acid supplementation under medical guidance. If you take a blood thinner, blood pressure medication, or NSAIDs, you need to check with your doctor or pharmacist before starting — the interaction potential is moderate and real.

Pregnancy safety data isn't on file, so discuss it with your healthcare provider if you're expecting. The side-effect profile is mild, but longer-term safety data is limited.

Likelihood Possible Evidence D
Nonsteroidal Anti-Inflammatory Drugs (Nsaids)

Theoretically, caprylic acid might increase plasma concentrations of NSAIDs.
In vitro research suggests that caprylic acid might displace NSAIDs from binding sites on albumin. This effect has not been reported in humans.

Warfarin (Coumadin)

Theoretically, caprylic acid might increase plasma concentrations of warfarin.
In vitro research suggests that high doses of caprylic acid might displace warfarin from albumin binding sites. This effect has not been reported in humans.

MCT/Butyrate Liquid by Douglas Laboratories: Common Questions

Does MCT/Butyrate Liquid by Douglas Laboratories interact with any medications?
Yes. Based on its ingredients, MCT/Butyrate Liquid has a known interaction with 262 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
MCT/Butyrate Liquid contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What are caprylic acid and butyric acid?
Caprylic acid is a medium-chain fat found in coconut oil and some dairy. Butyric acid is a short-chain fat that your gut bacteria naturally make. This product combines both in liquid form.
Can I take this if I'm on warfarin or another blood thinner?
Not without checking first. Caprylic acid may raise how much warfarin stays in your blood, raising bleeding risk. Talk to your doctor or pharmacist before you start — they can assess your individual situation.
What are the common side effects?
Most people tolerate it well short-term. The most common are mild stomach discomfort and a change in taste. A few have reported dizziness, headache, or fatigue.
Is this safe in pregnancy?
We don't have safety data for supplement doses in pregnancy. Talk with your doctor or pharmacist before taking it if you're pregnant — they can give you personalized advice.
Does this product actually work for epilepsy or tremor?
We don't have enough reliable evidence to say. The data on caprylic acid rates both as insufficient to make a claim.
What if I take ibuprofen or another NSAID pain reliever?
There's a moderate theoretical interaction — caprylic acid may raise NSAID levels in your blood. Check with your doctor or pharmacist before combining them, especially if you take NSAIDs regularly.
