HelloPharmacist Scorecard of MCT Oil 1,000 mg (1 g) by Carlson

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.

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 Triglyceride Oil” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Carlson's MCT Oil contains 2 active ingredients per capsule: caprylic acid and capric acid, both medium-chain fatty acids derived from coconut or palm oil. The capsule shell is the only inactive ingredient.

Medium-chain triglycerides are fatty acids with shorter carbon chains than those in most dietary fats, which your body absorbs and processes differently.

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 — one of this product's two active ingredients — is insufficient to establish reliable benefit. Studies suggest it's been explored for epilepsy and essential tremor, but we don't have data strong enough to confirm it works for either.

We hold no effectiveness rating for capric 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 recognized as safe when eaten in food amounts, but supplement doses are less well studied, so avoid them unless your doctor approves. Orally, it's generally well tolerated short-term, though a small number of people report mild abdominal discomfort, change in taste, dizziness, headache, or fatigue.

During breastfeeding, caprylic acid occurs naturally in breast milk, but the safety of concentrated supplement doses isn't known — use caution and talk with your doctor or pharmacist. We hold no safety data on capric 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, double-check with your doctor or pharmacist if you're on warfarin or other blood thinners (moderate risk of raised levels), antihypertensive drugs for high blood pressure (moderate risk of too-low pressure), or NSAIDs like ibuprofen or naproxen (moderate risk of raised NSAID levels). These interactions haven't been seen in patients yet, but the lab evidence is there.

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 a source of medium-chain triglycerides, but evidence doesn't yet establish that it's effective for epilepsy or essential tremor. If you take blood thinners like warfarin, antihypertensive drugs (blood pressure medications), or NSAIDs, check with your doctor or pharmacist before starting it — the interactions are theoretical but documented.

For most other people, short-term use seems well tolerated, though mild stomach discomfort can happen.

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.

MCT Oil 1,000 mg (1 g) by Carlson: Common Questions

Does MCT Oil 1,000 mg (1 g) by Carlson interact with any medications?
Yes. Based on its ingredients, MCT Oil 1,000 mg (1 g) 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 Oil 1,000 mg (1 g) 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 exactly is MCT oil, and why is it in this product?
MCT stands for medium-chain triglyceride — a type of fat with shorter carbon chains than regular dietary fats. Your body absorbs and uses them differently. This product delivers caprylic and capric acid, two MCTs, in softgel form.
Does this product actually work for epilepsy or tremor?
We don't have strong enough evidence to say caprylic acid works for either condition. Studies have looked at it, but the data isn't solid enough yet to recommend it for those uses.
What side effects might I notice?
Most people tolerate it fine short-term. Mild abdominal discomfort and changes in taste perception are the most commonly reported. Rarely, people report dizziness, headache, or fatigue.
Is it safe to take if I'm pregnant or breastfeeding?
For pregnancy: the safety data isn't on file. For breastfeeding: caprylic acid naturally appears in breast milk, but we don't know if supplement doses are safe. Talk with your doctor or pharmacist — they can weigh the specifics of your situation.
Can I take this with my other supplements?
The interactions we have data on are with medications like blood thinners, blood pressure drugs, and NSAIDs — not other supplements. If you're taking supplements alongside prescription medications, it's still worth running everything by your doctor or pharmacist.
