HelloPharmacist Scorecard of CLK With Slimpro Technology Raspberry Flavored Softgels by Cellucor

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.

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 4 active ingredients.
  • “Stimulant Free Toning Blend” is a proprietary blend — the label gives one combined amount (1,014 mg) without saying how much of each component you get.

CLK contains 4 active ingredients. L-carnitine tartrate is an amino acid compound that plays a role in how your body breaks down fat for energy.

Razberi-K raspberry ketones are compounds from raspberries that have been studied for potential effects on metabolism and body composition. The product also includes a Stimulant Free Toning Blend and Slimpro Protein Hydrolysates, though we hold no interaction data for the latter.

The remaining ingredients are inactive—gelatin capsule, glycerin, lecithin, beeswax, and food colorings and stabilizers.

Does it work?

Strong evidence
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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: L-carnitine deficiency — rated "Effective" (L-carnitine) (Natural Medicines).
  • On file: Angina — rated "Possibly Effective" (L-carnitine) (Natural Medicines).
  • On file: Congestive heart failure (CHF) — rated "Possibly Effective" (L-carnitine) (Natural Medicines).
  • On file: Hyperlipidemia — rated "Possibly Effective" (L-carnitine) (Natural Medicines).
  • On file: Myocarditis — rated "Possibly Effective" (L-carnitine) (Natural Medicines).

The evidence for this product's main ingredients is mixed. L-carnitine is effective for L-carnitine deficiency and possibly effective for high cholesterol, heart failure, and angina.

Raspberry ketones, however, have insufficient reliable evidence to establish whether they work for obesity or hair loss—the research just isn't there yet. If you're considering this product for weight loss, know that the evidence for its active ingredients doesn't yet support that claim.

The evidence, ingredient by ingredient L-carnitine Raspberry Ketone

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.

L-carnitine is generally well tolerated at typical doses, but some people report stomach upset, diarrhea, nausea, and a fishy body odor, especially at higher doses. Rarely, seizures have been reported.

Raspberry ketones, structurally similar to stimulant compounds, may cause heart palpitations, elevated blood pressure, and tremors in some people—case reports exist of serious arrhythmias. Overall, human safety data for high-dose raspberry ketone supplements is very limited.

Pregnancy safety for L-carnitine is not well established; for raspberry ketones, the data advises against use in pregnancy and while breastfeeding. L-carnitine safety while breastfeeding is also not well studied.

Side effects, ingredient by ingredient L-carnitine Raspberry Ketone

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?
  • 2 of the 2 matched ingredients can interact with medications — L-carnitine, Raspberry Ketone.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 191 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 with us before taking this product if you're on warfarin or other blood thinners (acenocoumarol)—both ingredients may affect how these work. Also flag thyroid hormone replacement, since L-carnitine may reduce its effectiveness.

If you take any stimulant drugs, the raspberry ketones may increase cardiovascular side effects. Run your exact medications through the checker on this page.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you have a documented L-carnitine deficiency or are exploring support for heart health or cholesterol, but you should absolutely check your medications first—especially if you take blood thinners like warfarin or any thyroid medication. If you have a heart condition or take stimulant drugs, talk with your pharmacist or doctor before starting.

The weight-loss claim isn't backed by strong evidence yet.

Razberi-K Raspberry Ketones2 drug types · 174 drugs

Stimulant Drugs

Theoretically, raspberry ketone might increase the risk of adverse cardiovascular effects with stimulant drugs.
Structurally, raspberry ketone resembles synephrine, a known stimulant agent. Heart palpitations, elevated blood pressure, coronary vasospasm, pulseless electrical activity arrest, and resistant polymorphic ventricular tachycardia have been reported in patients taking raspberry ketone.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, raspberry ketone might increase warfarin dose requirements.
In one case report, a patient taking warfarin 55 mg per week had a decrease in INR over a period of one month while taking raspberry ketone 250 mg daily. A warfarin dose increase to 70 mg per week was necessary to maintain a therapeutic INR while taking raspberry ketone. The mechanism for this potential interaction is not known.

Likelihood Possible Evidence D
Razberi-K Raspberry Ketones full monograph & interactions

L-Carnitine Tartrate3 drug types · 19 drugs

Acenocoumarol (Sintrom)

Theoretically, L-carnitine might increase the anticoagulant effects of acenocoumarol.
L-carnitine might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant similar to warfarin, but shorter-acting. There are at least two case reports of INR elevation with concomitant use. In one case, a 33-year-old male with a previously stable INR had an elevated INR of 4.65 after L-carnitine was started and continued for 10 weeks. INR normalized after discontinuation of the L-carnitine-containing product.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, L-carnitine might decrease the effectiveness of thyroid hormone replacement.
L-carnitine appears to act as a peripheral thyroid hormone antagonist by inhibiting entry of thyroid hormone into the nucleus of cells. Taking L-carnitine also seems to diminish some of the symptoms of hyperthyroidism.

Likelihood Probable Evidence B
Warfarin (Coumadin)

Theoretically, L-carnitine might increase the anticoagulant effects of warfarin.
L-carnitine might increase the anticoagulant effects of acenocoumarol, a shorter-acting oral anticoagulant similar to warfarin. There is not enough information to know whether this interaction occurs with L-carnitine and warfarin.

CLK With Slimpro Technology Raspberry Flavored Softgels by Cellucor: Common Questions

Does CLK With Slimpro Technology Raspberry Flavored Softgels by Cellucor interact with any medications?
Yes. Based on its ingredients, CLK With Slimpro Technology Raspberry Flavored Softgels has a known interaction with 191 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
CLK With Slimpro Technology Raspberry Flavored Softgels 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.
Can I take this if I'm on warfarin?
Not without checking with your pharmacist first. Both L-carnitine and raspberry ketones interact with warfarin—L-carnitine may strengthen its blood-thinning effect, while raspberry ketones may weaken it. Your dose may need adjustment, so don't start this without reviewing it with your provider.
Will this product help me lose weight?
The evidence doesn't establish that yet. L-carnitine is possibly effective for high cholesterol and heart conditions, but for weight loss specifically, the research is still insufficient. Raspberry ketones have no reliable evidence for obesity either.
What are the most common side effects?
From L-carnitine, you might experience stomach upset, diarrhea, nausea, or a fishy body odor. Raspberry ketones, which resemble stimulants, may cause heart palpitations, elevated blood pressure, or shakiness, though these are less common.
Is this safe during pregnancy?
There's not enough safety data for L-carnitine in pregnancy. For raspberry ketones, the data advises against use during pregnancy. Talk with your doctor before taking this if you're pregnant or planning to become pregnant.
Can I take this while breastfeeding?
L-carnitine is possibly safe while breastfeeding, but data is limited. Raspberry ketones should not be used while breastfeeding due to insufficient safety information. Discuss your situation with your pharmacist or doctor.
What is L-carnitine tartrate, and why is it in this product?
L-carnitine is an amino acid your body uses to break down fat for energy. It's included in this product for its potential metabolic and cardiovascular support, though it's particularly established as effective for L-carnitine deficiency.
