HelloPharmacist Scorecard of KEEN by BELDT Labs

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 Triglycerides” is listed as a grouped ingredient — the label gives one combined amount (3,000 mg) without saying how much of each component you get.

KEEN contains 2 active ingredients: caprylic acid and capric acid. Caprylic acid is a type of fat (a medium-chain fatty acid) that may play a role in managing seizures or tremor, though the evidence is still too limited to say for sure.

The product also includes gelatin and vitamin E as inactive ingredients.

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: ketogenic support and fat-burning energy.
  • We looked for evidence on: weight management, metabolic health, mental clarity.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for caprylic acid in epilepsy and essential tremor is insufficient — we don't have enough reliable data to know whether it works for either condition. If you're considering KEEN for one of these uses, talk with your doctor about what the current science supports and what other options might be available.

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 amounts, but supplement doses haven't been as well studied — avoid using this product unless your doctor approves. Most people who take caprylic acid short-term tolerate it well, though some report mild stomach discomfort or a change in taste.

Rarely, mild dizziness, headache, and fatigue have been reported. Caprylic acid appears naturally in breast milk, but the safety of concentrated supplement doses during nursing isn't known; if you're pregnant or breastfeeding, talk with your doctor or pharmacist before taking KEEN.

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.

Before taking KEEN, check with your doctor or pharmacist if you take blood thinners (especially warfarin/Coumadin), blood pressure medications, or NSAIDs like ibuprofen or naproxen. Caprylic acid may theoretically increase your blood levels of these drugs or change how they work, though human evidence is limited.

Altogether, these interactions span 262 individual medications.

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.

KEEN is designed around caprylic acid, a compound studied for seizure and tremor management — but the evidence isn't yet solid enough to say it works. If you take blood thinners, blood pressure medications, or NSAIDs, you'll want to check with your own doctor or pharmacist before starting, since caprylic acid may theoretically affect how your body handles these drugs.

Because supplement doses are less well studied than food amounts, it's wise to get your healthcare provider's approval before you use it.

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.

KEEN by BELDT Labs: Common Questions

Does KEEN by BELDT Labs interact with any medications?
Yes. Based on its ingredients, KEEN 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?
KEEN 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 is caprylic acid and why is it in this product?
Caprylic acid is a medium-chain fatty acid — a type of fat found naturally in coconut oil and other sources. It's included in KEEN because early research suggests it might help with seizures or tremor, though we don't yet have enough solid evidence to confirm that.
Will KEEN work for epilepsy or tremor?
The evidence isn't established yet. Caprylic acid has shown some promise, but the data is too limited for us to say whether it actually works. If you're thinking about using it for either condition, talk with your doctor about whether it's right for you.
What side effects might I get from KEEN?
Most people tolerate caprylic acid well short-term. Some experience mild stomach discomfort or a change in taste. Rarely, people report mild dizziness, headache, or fatigue. If you notice any of these, let your pharmacist know.
Is it safe to take KEEN if I'm pregnant or breastfeeding?
There isn't enough data to know whether concentrated supplement doses are safe during pregnancy or nursing. Caprylic acid occurs naturally in breast milk, but we don't have safety information for the higher doses in supplements. Talk with your doctor or pharmacist for personalized advice.
Can I take KEEN with ibuprofen or other pain relievers?
Caprylic acid may theoretically increase blood levels of NSAIDs like ibuprofen and naproxen, though this hasn't been reported in humans. Check with your doctor or pharmacist before combining them, especially if you take NSAIDs regularly.
