HelloPharmacist Scorecard of M.C.T. 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

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

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 (14 Gram(s)) without saying how much of each component you get.

This product contains 2 active ingredients: caprylic acid and capric acid — both medium-chain fats (fatty acids) extracted and concentrated for supplement use. These are naturally occurring compounds that work quickly in the body compared to longer-chain fats.

There are no inactive ingredients listed.

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 on caprylic acid is insufficient to rate its use for epilepsy or essential tremor. Because the data doesn't establish reliable benefit for these purposes, we can't claim this product works for them.

You'll want to ask your doctor or pharmacist whether there's a case for trying it in your situation.

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 recognized as safe in food amounts, but supplement doses — the kind in this product — are less well studied. Short-term use appears well tolerated; the most common side effects reported are mild stomach discomfort and a change in taste.

A small number of people have reported dizziness, headache, or fatigue. Because caprylic acid appears naturally in breast milk, its safety in concentrated supplement form during lactation isn't known — use with caution and check with your doctor or pharmacist first.

Pregnancy safety data for this ingredient isn't on file, so talk with your healthcare provider before using it if you're pregnant or planning to become pregnant.

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.

Before taking this product, check with your doctor or pharmacist if you take blood thinners (like warfarin), blood pressure medications, or NSAIDs — all have Moderate-severity interactions documented with caprylic acid. We were unable to check capric acid for interactions because we hold no data on it.

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.

M.C.T. from Douglas Laboratories may appeal to someone exploring medium-chain fat supplementation, but if you take blood thinners, blood pressure medications, or NSAIDs, you need to check with your doctor or pharmacist first — the interactions are theoretical but plausible. The safety and effectiveness evidence for epilepsy and tremor is too thin to rely on.

Start the conversation with your healthcare provider.

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.
