HelloPharmacist Scorecard of MCT//143 by Pruvit

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.

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 6 of its 6 active ingredients.
  • “Medium Chain Tryglcerides” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

MCT//143 is a medium-chain triglyceride (MCT) powder with 6 active ingredients: caprylic acid (C8:0), capric acid (C10:0), lauric acid (C12:0), myristic acid (C14:0), palmitic acid (C16:0), and linoleic acid (C18:2). These are fatty acids that your body can convert into a type of fuel called ketones, which some people use for energy during fasting or low-carb diets.

The powder also contains inactive ingredients: extra virgin organic coconut oil and purified phosphatidylcholine (a fat-based compound).

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: ketosis support.
  • We looked for evidence on: weight management, energy metabolism, ketogenic diet support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The data we hold shows insufficient evidence to rate caprylic acid for epilepsy or essential tremor. Lauric acid is rated insufficient evidence for bronchitis, vaginal yeast infections, common cold, and genital herpes.

In short, evidence for what this product is used for isn't established in our records.

The evidence, ingredient by ingredient Caprylic Acid Lauric 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • 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 are less well studied — if you want to use it, have your doctor approve first. Short-term use appears well tolerated, though some people report mild belly discomfort, taste changes, dizziness, headache, or fatigue.

Lauric acid is likely safe in pregnancy; it occurs naturally in breast milk, though concentrated supplement safety while nursing isn't established. Caprylic acid's safety at supplement doses during pregnancy or breastfeeding is unknown, so use caution or ask your doctor or pharmacist for personalized advice.

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 2 matched ingredients 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 take this product, check with your doctor or pharmacist if you're on warfarin or another blood thinner, blood pressure medications (antihypertensives), or NSAIDs like ibuprofen. These are the medication types most likely to interact with caprylic acid in this product.

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 may interact with blood thinners, blood pressure medications, and anti-inflammatory drugs—mainly in theory, but seriously enough that you should check your exact medications first. If you take any prescription drugs, run them through the tool on this page before starting MCT//143.

Talk it over with your doctor or pharmacist to make sure it's right for you and your health situation.

C8:0 - Caprylic Acid3 drug types · 262 drugs

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//143 by Pruvit: Common Questions

Does MCT//143 by Pruvit interact with any medications?
Yes. Based on its ingredients, MCT//143 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//143 contains 6 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 does MCT//143 do?
It's a medium-chain triglyceride supplement — fatty acids your body can turn into ketones for fuel. The evidence for what it's marketed for (epilepsy, tremor, or viral infections) isn't established in our data, so talk to your doctor about whether it's right for your specific use.
Does this have any fillers or junk?
The active ingredients are the fatty acids. It also contains extra virgin organic coconut oil and a purified compound called phosphatidylcholine as inactive ingredients.
Is it safe if I'm pregnant or nursing?
Lauric acid (one of the ingredients) is likely safe in pregnancy. Caprylic acid safety at supplement doses during pregnancy or breastfeeding isn't established — there's just not enough data. Talk with your doctor or pharmacist about what's safe for you personally.
What side effects might I get?
Short-term use seems well tolerated overall. Some people report mild belly discomfort, taste changes, dizziness, headache, or fatigue. Nausea might be more common if given at certain high rates directly into the small intestine, but oral use rates are unknown.
Can it raise my cholesterol?
Lauric acid is a saturated fat that raises both LDL ('bad') and HDL ('good') cholesterol, so the overall heart risk may be less than other saturated fats. It doesn't seem to affect triglycerides.
