HelloPharmacist Scorecard of Medium Chain Triglycerides 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 5 of its 6 active ingredients.

This product contains 6 ingredients total. The active ones are caprylic acid, capric acid, lauric acid, caproic acid, and 100% structured lipids—all medium-chain fats that your body can use for quick energy.

These are the working ingredients. The inactive ones are gelatin (the capsule itself) and water.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

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 any of these ingredients work reliably for the conditions listed. Caprylic acid and caproic acid both show insufficient reliable evidence for epilepsy and essential tremor.

Lauric acid shows insufficient evidence for bronchitis, vaginal yeast infections, genital herpes, and the common cold. In short, we don't have the data to say whether this product actually does what it's claimed to do.

The evidence, ingredient by ingredient Caprylic Acid Lauric 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Caprylic acid and caproic acid are generally recognized as safe in food, but supplement doses—like the amount in this product—haven't been studied as well, so caution is wise. The most common side effects from caprylic acid are mild stomach discomfort and a change in how things taste.

A small number of people have reported mild dizziness, headache, or fatigue. Lauric acid in large amounts can raise cholesterol levels, though it tends to raise the protective kind (HDL) along with the less protective kind (LDL).

For pregnancy: lauric acid is rated likely safe, but safety data for caprylic acid and caproic acid at supplement doses aren't firm enough—talk with your doctor before use. Caprylic and caproic acid do occur naturally in breast milk, but whether concentrated supplements are safe while nursing isn't established; again, check with your doctor or pharmacist first.

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 2 matched ingredients 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 with your pharmacist if you take blood pressure medications (Moderate risk of low blood pressure), NSAIDs like ibuprofen or naproxen (Moderate risk of higher drug levels), or warfarin (Moderate risk of higher drug levels). No interactions are documented for the other ingredients we could check.

The bottom line

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

If you take blood pressure medication, NSAIDs, or warfarin, you'll want to check this product against your exact medications before starting—the interactions are theoretical but documented. If you're pregnant or nursing, there's not enough safety data on the caprylic and caproic acid at supplement doses, so get personalized advice from your doctor.

We also don't have solid evidence yet that this product works for the conditions it's marketed for.

Caprylic Acid3 drug types · 262 drugs

Antihypertensive Drugs

Theoretically, caprylic acid might increase the risk of hypotension when used with antihypertensive drugs.
Animal research suggests that caprylic acid might have positive inotropic effects, resulting in reduced arterial pressure and vascular resistance and increased cardiac output.

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.

Likelihood Possible Evidence D
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.

Medium Chain Triglycerides by Douglas Laboratories: Common Questions

Does Medium Chain Triglycerides by Douglas Laboratories interact with any medications?
Yes. Based on its ingredients, Medium Chain Triglycerides 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?
Medium Chain Triglycerides contains 6 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.
Will this product lower my blood pressure?
Medium-chain triglycerides aren't proven to work for blood pressure control, and caprylic acid might theoretically lower blood pressure further if you're already on a medication for it. Don't rely on this as a blood pressure treatment—talk with your doctor about what's right for you.
What's the most common side effect?
Mild stomach discomfort and a change in taste are the most commonly reported side effects from caprylic acid. They tend to be mild and short-term.
Is this safe to take while pregnant?
Lauric acid is rated likely safe in pregnancy, but caprylic acid and caproic acid don't have enough safety data at supplement doses to say yes or no. Talk with your doctor before taking this during pregnancy.
Can I take this while breastfeeding?
These acids occur naturally in breast milk, but we don't have solid safety data on concentrated supplements while nursing. Check with your doctor or pharmacist to be sure it's right for you.
Does this product actually work for anything?
The evidence we have is insufficient to say whether it works for epilepsy, essential tremor, bronchitis, cold, herpes, or yeast infection. There's simply not enough reliable research on these ingredients for those uses.
