HelloPharmacist Scorecard of MCT Oil Rx by Taylor MD Formulations

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

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 2 of its 3 active ingredients.
  • “Monounsaturated Fat” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

MCT Oil Rx is a powder form of medium-chain triglyceride oil. It has three active ingredients: polyunsaturated fat, monounsaturated fat, and caprylic acid.

The product also contains medium-chain triglyceride oil as an inactive ingredient. MCT oils are a type of fat designed for rapid absorption and are commonly used in nutrition-focused formulas.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: increases energy expenditure.
  • We looked for evidence on: energy metabolism, metabolic rate, physical performance.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for caprylic acid's effectiveness in epilepsy and essential tremor is insufficient — we don't have reliable data showing it works for these purposes. The data we hold doesn't establish that this product is effective for any particular use.

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 eaten in food amounts, but supplement doses haven't been studied as thoroughly, so the company recommends you get your doctor's approval before using this product at supplement levels. Short-term, orally taken caprylic acid is well tolerated in most people.

A small number of users have reported mild abdominal discomfort, change in taste, mild dizziness, headache, or fatigue. Caprylic acid occurs naturally in breast milk, but the safety of concentrated supplement doses during pregnancy and lactation isn't established — talk with your doctor or pharmacist before use if you're pregnant or nursing.

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 you start MCT Oil Rx, double-check if you take warfarin (Coumadin) or other blood thinners — caprylic acid may raise their levels. Also run through any blood pressure medications and NSAIDs like ibuprofen or naproxen, as caprylic acid could affect both.

Use the medication search tool on this page to confirm your exact drugs.

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.

This product may be worth considering if you're looking for an MCT oil supplement and your doctor approves. If you take blood thinners like warfarin, blood pressure medications, or NSAIDs, check your specific drugs with the tool on this page before starting — caprylic acid may interact with all three.

A quick conversation with your pharmacist can tell you whether it's safe to add alongside what you're already taking.

Label statements

Formula

Medium-chain triglycerides (MCT) are short and medium length chain fatty acids which are more easily absorbed and digested by the body than other fats. MCT are found in coconut oil and palm oil. MCT oil increases energy expenditure and provides an energy boost without increasing body fat while decreasing fat storage. MCT oil helps balance blood sugar levels and promotes healthy hormone function by boosting the metabolism. MCT oil burns fat quickly and is not stored by the body. MCT do not cause weight gain because they stimulate thermogenesis, a process in which the body generates energy, or heat, by increasing its normal metabolic, fat-burning rate. Studies suggest that substituting MCT oil for other fats may help support healthy weight and body composition. MCT oil helps maintain heart, immunity and gastrointestinal system health. MCT oil may improve appetite control and absorption of calcium, magnesium and amino acids. MCT oil may improve brain health when combined with a ketogenic diet.

Formulation

MCT oil do not supply essential fatty acids (EFA) and the best sources for these are safflower oil, canola oil or olive oil or fish.

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.
