HelloPharmacist Scorecard of MCT Oil 1000 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.

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 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.

This product delivers 1 gram (1,000 mg) of medium chain triglyceride oil in each softgel. MCT oil is made up of two main fatty acids: caprylic acid and capric acid.

The capsule shell itself is the only inactive ingredient.

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 for epilepsy or essential tremor — the ratings are insufficient. MCT oil is widely used in nutrition, but reliable evidence for specific health claims isn't on file for this product.

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, but supplement doses haven't been studied as thoroughly, so it's wise to get your doctor's approval before starting. Short-term oral use appears well tolerated in most people.

A small number of users have reported mild abdominal discomfort, changes in taste, dizziness, headache, or fatigue. Caprylic acid does occur naturally in breast milk, but concentrated supplement safety during lactation isn't well established — talk with your doctor or pharmacist if you're breastfeeding.

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 taking this if you use blood pressure medications, pain relievers like ibuprofen or naproxen (NSAIDs), or the blood thinner warfarin — caprylic acid may affect how much of these drugs your body absorbs. None of the other interactions we hold data on are documented for capric acid or the overall MCT blend, so confirm your specific medications with your doctor or pharmacist.

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.

MCT oil is a straightforward supplement for people looking to add medium chain triglycerides to their diet. If you take blood pressure medication, NSAIDs like ibuprofen, or warfarin, you'll want to check with your own doctor or pharmacist first — the interactions documented here are theoretical but worth confirming.

Anyone else should still run their full medication list through the tool on this page before starting.

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.

What is MCT oil, and what's in this product?

Will this cause side effects?
Short-term use is generally well tolerated. Some people report mild abdominal discomfort, changes in taste, dizziness, headache, or fatigue, but these are uncommon. Start with a lower dose if you're new to MCT oil.
Is it safe to take while breastfeeding?

Does this actually work for seizures or tremors?
We don't have enough reliable evidence to say whether caprylic acid helps with epilepsy or essential tremor. The evidence is insufficient to make a rating.
Can I take this if I'm on blood pressure medication?
Caprylic acid may theoretically lower your blood pressure further when combined with blood pressure drugs — a Moderate concern. Check with your own doctor or pharmacist before adding this supplement.
