HelloPharmacist Scorecard of MCT Oil by Herbal Secrets

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 Aug 20, 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 3 of its 5 active ingredients.

Herbal Secrets MCT Oil contains 5 ingredients: caprylic acid, capric acid, and medium chain triglyceride are the active components that make up the oil itself, along with polyunsaturated and monounsaturated fats. The inactive ingredient listed is medium chain triglyceride oil, which serves as a carrier and filler.

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 data we hold shows insufficient reliable evidence to rate caprylic acid for epilepsy or essential tremor. We don't have effectiveness information on file for the other active ingredients in 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 when consumed in food amounts, but supplement doses haven't been well studied. Short-term oral use appears well tolerated overall.

The most common side effects reported are mild abdominal discomfort and changes in taste; rarely, people have reported mild dizziness, headache, or fatigue. Caprylic acid occurs naturally in breast milk, but safety data for concentrated supplements during pregnancy and lactation isn't established — talk with your doctor or pharmacist before using this product if you're pregnant or breastfeeding.

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 if you're on blood thinners like warfarin, blood pressure medications, or NSAIDs — caprylic acid may theoretically raise levels of all three in your blood. None of these effects have been seen in real patients yet, but the possibility is documented enough that it's worth confirming with your doctor or pharmacist.

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.

MCT Oil can be a straightforward supplement, but because caprylic acid interacts with blood thinners, blood pressure medications, and NSAIDs, you'll want to check your specific medications first. If you take warfarin or any of those drug classes, confirm with your doctor or pharmacist before starting.

Even if you're not on those, it's worth a quick conversation with your healthcare provider about whether this product fits your routine.

Formula

Herbal Secrets MCT (Medium Chain Triglycerides) Oil is fractionated Coconut Oil and Palm Kernel Oil. MCT Oil is colorless, virtually odorless and stable due to the high content of Medium Chain Triglycerides, Caprylic Acid (C8) and Capric Acid (C10). MCTs are rapidly absorbed by the body and are quickly metabolized into well sustained energy for immediate use by the organs and muscles. MCT Oil supports brain health as it may help enhance ketones, which are efficient fuel for your brain. In addition, MCTs aid in healthy weight management by helping to suppress appetite benefiting those attempting to lower their intake of total calories.

Medium Chain Triglycerides

Suggested/Recommended/Usage/Directions

Suggested Use: As a dietary supplement, take one (1) tablespoon 1 to 3 times daily, or as directed by your health care professional. MCT Oil can also be used as a substitute for conventional oils in salad dressings, sauces or cooking as a source of beneficial fatty acids. Not recommended for use in frying due to low boiling point.

Precautions

Warning: For adults only.

MCT Oil may cause GI upset. To reduce these effects, take with food.

Consult a health care professional before consumption if pregnant/nursing, taking medication, or have a medical condition.

Keep out of reach of children.

Do not use if safety seal is damaged or missing.

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 by Herbal Secrets: Common Questions

Does MCT Oil by Herbal Secrets interact with any medications?
Yes. Based on its ingredients, MCT Oil 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 contains 4 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 is caprylic acid, and why is it in this product?
Caprylic acid is one of the active medium chain fatty acids in MCT oil. It's a naturally occurring fat that's part of what makes this product work, though we don't have strong evidence yet for how well it performs for the conditions it's been studied in.
Will this product upset my stomach?
Mild abdominal discomfort and changes in taste are the most common side effects people report. Most find caprylic acid well tolerated when taken orally in the short term, though longer-term safety data is limited.
Is MCT Oil safe to take while pregnant or breastfeeding?
We don't have enough safety data to know either way. Caprylic acid does occur naturally in breast milk, but concentrated supplement safety during pregnancy and lactation isn't established. Talk with your doctor or pharmacist before using this if you're pregnant or nursing — they can weigh the pros and cons for your situation.
Can I take this if I'm on ibuprofen or naproxen?
There's a moderate theoretical interaction — caprylic acid might raise how much NSAID stays in your blood — but it hasn't been seen in actual patients. Still, check with your doctor or pharmacist before combining them to be safe.
Is there any evidence this helps with epilepsy or essential tremor?
We hold insufficient reliable evidence to say whether caprylic acid works for either condition. If you're considering it for one of those reasons, that's a conversation to have with your doctor rather than something to self-treat.
