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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Super CLA Blend contains three active ingredients. Conjugated linoleic acid (CLA) is a fatty acid derived from dairy and beef.

Sesame seed lignan extract is a concentrated form of compounds from sesame seeds. Guarana extract is derived from a South American plant and contains caffeine as its active component.

The softgel also includes several inactive ingredients—gelatin, glycerin, maltodextrin, purified water, silica, sunflower lecithin, carob color, and rosemary extract—which serve as binders, thickeners, and preservatives.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Concentrated conjugated linoleic acid blend.
  • We looked for evidence on: Hyperlipidemia, Obesity, Metabolic syndrome, Cardiovascular disease (CVD), Body composition, Weight management — and 1 related terms.
  • The closest evidence on file: Guarana is rated "Insufficient Reliable Evidence To Rate" for Obesity (Natural Medicines).
  • Also on file: Sesame is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD), Hyperlipidemia, Obesity, Metabolic syndrome.

The evidence for sesame seed lignan extract shows it is possibly effective for high blood pressure; clinical research suggests it can lower both systolic and diastolic readings. For other conditions—nonalcoholic fatty liver disease, HIV-related wasting, Alzheimer disease, and anemia of chronic disease—the evidence is insufficient to rate it.

Sesame was rated possibly ineffective for cough. For guarana extract, the evidence is insufficient to establish effectiveness for cancer-related appetite loss, anxiety, athletic performance, cancer-related fatigue, or chemotherapy-related fatigue.

The data we hold does not address effectiveness for other uses.

The evidence, ingredient by ingredient Sesame Guarana

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.

Sesame seed lignan extract is generally well tolerated in food amounts, but it is a major allergen. Allergic reactions—ranging from skin rashes, itching, and swelling to respiratory and gastrointestinal symptoms—have been reported after oral exposure.

One study found up to 0.5% of the U.S. population reports a sesame allergy. A single case of diarrhea was noted in a clinical trial.

Concentrated sesame supplements are less well studied than food amounts, so caution is advised. Guarana's high caffeine content makes it generally well tolerated only in small amounts.

Large doses can cause stomach burning, nausea, dizziness, insomnia (especially in children), nervousness, restlessness, tremors, headache, anxiety, and agitation. Caffeine can trigger anaphylaxis in sensitive individuals, though true allergy to caffeine is rare.

During pregnancy, guarana should be avoided due to its caffeine content. While breastfeeding, caffeine passes into breast milk, so it should be avoided or limited.

For sesame, safety data in pregnancy and while breastfeeding is not well established in concentrated supplement form; talk with your doctor.

Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Guarana, Sesame.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 923 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.

Stop and check with your pharmacist if you take ephedrine or ephedra (a stimulant medication) — the caffeine in guarana creates a Major risk for serious stimulant adverse effects. Also double-check before starting if you take blood pressure medications (antihypertensives), diabetes medications, seizure medications (valproate, felbamate, carbamazepine), fluvoxamine (an antidepressant), disulfiram (Antabuse), dipyridamole (Persantine), clozapine (Clozaril), or tamoxifen (Nolvadex).

These interactions are Moderate in severity.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

This product is worth a careful medication check before you start. If you take blood pressure or diabetes medications, seizure medications, or any of the specific drugs listed in the med_watch section below, have your pharmacist review it first.

The guarana caffeine content makes this a poor choice if you're pregnant or breastfeeding, and the sesame allergen is a serious concern if you have a known sesame allergy.

For each ingredient in Super CLA Blend with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Guarana (Paullinia cupana) extract41 drug types · 655 drugs

Ephedrine

Theoretically, concomitant use might increase the risk for stimulant adverse effects.
Guarana contains caffeine. Use of ephedrine with caffeine can increase the risk of stimulatory adverse effects. There is evidence that using ephedrine with caffeine might increase the risk of serious life-threatening or debilitating adverse effects such as hypertension, myocardial infarction, stroke, seizures, and death.

Likelihood Probable Evidence D
Adenosine (Adenocard)

Theoretically, guarana might decrease the vasodilatory effects of adenosine and interfere with its use prior to stress testing.
Guarana contains caffeine. Caffeine is a competitive inhibitor of adenosine at the cellular level. However, caffeine does not seem to affect supplemental adenosine because high interstitial levels of adenosine overcome the antagonistic effects of caffeine. It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests. However, methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing.

Likelihood Possible Evidence B
Anticoagulant/Antiplatelet Drugs

Theoretically, guarana may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that guarana extract can inhibit platelet aggregation. This effect may be due to the caffeine in guarana, which is also reported to have antiplatelet activity. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Beta-Adrenergic Agonists

Theoretically, concomitant use might increase the clinical effects of beta-adrenergic agonists.
Guarana contains caffeine. Theoretically, concomitant use of large amounts of caffeine might increase cardiac inotropic effects of beta-agonists.

Likelihood Probable Evidence D
Carbamazepine (Tegretol)

Theoretically, guarana might reduce the effects of carbamazepine and increase the risk for convulsions.
Animal research suggests that taking caffeine can lower the anticonvulsant effects of carbamazepine and can induce seizures when given to animals in doses above 400 mg/kg. Human research has shown that taking caffeine 300 mg in three divided doses along with carbamazepine 200 mg reduces the bioavailability of carbamazepine by 32% and prolongs the plasma half-life of carbamazepine two-fold in healthy individuals.

Likelihood Possible Evidence D
Cimetidine (Tagamet)

Theoretically, concomitant use might increase the effects and adverse effects of caffeine in guarana.
Guarana contains caffeine. Cimetidine decreases the rate of caffeine clearance by 31% to 42%.

Likelihood Likely Evidence B
Clozapine (Clozaril)

Theoretically, guarana might increase the levels and adverse effects of clozapine and acutely exacerbate psychotic symptoms.
Guarana contains caffeine. Caffeine can increase the effects and toxicity of clozapine. Caffeine doses of 400-1000 mg per day inhibit clozapine metabolism. Clozapine is metabolized by cytochrome P450 1A2 (CYP1A2). Researchers speculate that caffeine might inhibit CYP1A2. However, there is no reliable evidence that caffeine affects CYP1A2. There is also speculation that genetic factors might make some patients more sensitive to the interaction between clozapine and caffeine.

Likelihood Possible Evidence B
Dipyridamole (Persantine)

Theoretically, guarana might decrease the vasodilatory effects of dipyridamole and interfere with its use prior to stress testing.
Guarana contains caffeine. Caffeine might inhibit dipyridamole-induced vasodilation. It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests. Methylxanthines appear more likely to interfere with dipyridamole than adenosine-induced stress testing.

Likelihood Probable Evidence B
Disulfiram (Antabuse)

Theoretically, disulfiram might increase the risk of adverse effects from caffeine.
In human research, disulfiram decreases the clearance and increases the half-life of caffeine.

Likelihood Probable Evidence D
Diuretic Drugs

Theoretically, using guarana with diuretic drugs might increase the risk of hypokalemia.
Guarana contains caffeine. Caffeine, especially in excessive amounts, can reduce potassium levels due to stimulation of the sodium-potassium pump. Diuretics can also lower potassium levels.

Likelihood Possible Evidence D
Estrogens

Theoretically, estrogens might increase the levels and adverse effects of caffeine.
Guarana contains caffeine. Estrogen inhibits caffeine metabolism.

Likelihood Probable Evidence B
Ethosuximide (Zarontin)

Theoretically, guarana might reduce the effects of ethosuximide and increase the risk for convulsions.
Guarana contains caffeine. Animal research shows that caffeine 92.4 mg/kg can decrease the anticonvulsant activity of ethosuximide. This effect has not been observed in humans.

Likelihood Possible Evidence D
Felbamate (Felbatol)

Theoretically, guarana might reduce the effects of felbamate and increase the risk for convulsions.
Guarana contains caffeine. Animal research shows that a high dose of caffeine 161.7 mg/kg can decreases the anticonvulsant activity of felbamate. This effect has not been observed in humans.

Likelihood Possible Evidence D
Flutamide (Eulexin)

Theoretically, guarana might increase the levels and adverse effects of flutamide.
Guarana contains caffeine. In vitro evidence shows that caffeine can inhibit the metabolism of flutamide. However, this effect has not been reported in humans.

Likelihood Probable Evidence D
Fluvoxamine (Luvox)

Theoretically, fluvoxamine might increase the levels and adverse effects of caffeine.
Guarana contains caffeine. Fluvoxamine reduces caffeine metabolism.

Likelihood Probable Evidence D
Lithium

Theoretically, abrupt guarana withdrawal might increase the levels and adverse effects of lithium.
Guarana contains caffeine. Theoretically, abrupt caffeine withdrawal might increase serum lithium levels. There are two case reports of lithium tremor that worsened upon abrupt coffee withdrawal.

Likelihood Probable Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, concomitant use might increase the risk of a hypertensive crisis.
Guarana contains caffeine. Caffeine has been shown to inhibit MAO-A and -B in laboratory studies. Concomitant intake of large amounts of caffeine with MAOIs might precipitate a hypertensive crisis. In a case report, a patient that consumed 10-12 cups of caffeinated coffee and took the MAOI tranylcypromine presented with severe hypertension. Hypertension was resolved after the patient switched to drinking decaffeinated coffee.

Likelihood Possible Evidence D
Nicotine

Theoretically, concomitant use might increase the risk of hypertension.
Guarana contains caffeine. Concomitant use of caffeine and nicotine has been shown to have additive cardiovascular effects, including increased heart rate and blood pressure. Blood pressure was increased by 10.8/12.4 mmHg when the agents were used concomitantly.

Likelihood Probable Evidence D
Pentobarbital (Nembutal)

Theoretically, guarana might decrease the effects of pentobarbital.
Guarana contains caffeine. In vivo evidence suggests that caffeine can negate the hypnotic effects of pentobarbital in humans. However, animal research suggests that guarana does not alter the hypnotic effect of pentobarbital.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

Theoretically, guarana might reduce the effects of phenobarbital and increase the risk for convulsions.
Guarana contains caffeine. Animal research shows that caffeine can decrease the anticonvulsant activity of phenobarbital. The exact mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Phenylpropanolamine

Theoretically, phenylpropanolamine might increase the risk of hypertension, as well as the levels and adverse effects of caffeine.
Guarana contains caffeine. Concomitant use of phenylpropanolamine and caffeine might cause an additive increase in blood pressure. Phenylpropanolamine also seems to increase caffeine serum levels.

Likelihood Probable Evidence B
Phenytoin (Dilantin)

Theoretically, guarana might reduce the effects of phenytoin and increase the risk for convulsions.
Guarana contains caffeine. Animal research shows that caffeine can decrease the anticonvulsant activity of phenytoin. The effect does not seem to be related to the seizure threshold-lowering effects of caffeine. However, the exact mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Pioglitazone (Actos)

Theoretically, guarana might increase the levels and clinical effects of pioglitazone.
Guarana contains caffeine. Animal research suggests that caffeine can modestly increase the maximum concentration, area under the curve, and half-life of pioglitazone, and also reduce its clearance. This increased the antidiabetic effects of pioglitazone. However, the exact mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Riluzole (Rilutek)

Theoretically, concomitant use might increase the levels and adverse effects of both caffeine and riluzole.
Guarana contains caffeine. Caffeine and riluzole are both metabolized by cytochrome P450 1A2 (CYP1A2), and concomitant use might reduce the metabolism of one or both agents.

Likelihood Possible Evidence D
Stimulant Drugs

Theoretically, concomitant use might increase stimulant adverse effects.
Guarana contains caffeine. Due to the central nervous system (CNS) stimulant effects of caffeine, concomitant use with stimulant drugs can increase the risk of adverse effects.

Likelihood Possible Evidence D
Guarana (Paullinia cupana) extract full monograph & all 41 interactions

Sesame seed Lignan extract5 drug types · 528 drugs

Antidiabetes Drugs

Taking sesame oil with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical studies show that sesame oil can decrease plasma glucose and glycated hemoglobin (HbA1c) levels. Some clinical research in patients taking glibenclamide shows that using sesame oil or a blend of sesame oil and rice bran oil in place of other oil for cooking reduces plasma glucose more than glibenclamide alone. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Antihypertensive Drugs

Taking sesame oil with antihypertensive drugs might increase the risk of hypotension.
Clinical research shows that replacing other cooking oil with sesame oil can lower systolic blood pressure (SBP) and diastolic blood pressure (DBP) in patients with or without hypertension. There is also some evidence that sesame oil has additive effects in patients also taking atenolol, nifedipine, and/or hydrochlorothiazide. In patients using nifedipine, using a blend of sesame oil and rice bran oil for cooking reduces both SBP and DBP more than nifedipine alone.

Likelihood Probable Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, sesame might increase the levels and clinical effects of CYP2C9 substrates.
In vitro, sesame inhibits CYP2C9. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, sesame might interfere with tamoxifen.
In animal research, sesame seed reduces the tumor-inhibitory effect of tamoxifen by reducing apoptosis and increasing proliferation. This interaction has not been reported in humans.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, sesame might alter the transport of P-glycoprotein substrates.
In vitro research suggests that sesamin, a constituent of sesame, can inhibit the multi-drug transporter protein, P-glycoprotein. However, this interaction has not been reported in humans.

Super CLA Blend by Life Extension: Common Questions

Does Super CLA Blend by Life Extension interact with any medications?
Yes. Based on its ingredients, Super CLA Blend has a known interaction with 923 medications, including 8 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Super CLA Blend contains 3 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 pregnant?
You should avoid Super CLA Blend during pregnancy. Guarana's high caffeine content makes it unsafe in pregnancy. Sesame safety in concentrated supplements during pregnancy is not well studied. Talk with your doctor before taking any supplement while pregnant.
What is conjugated linoleic acid (CLA) supposed to do?
CLA is a fatty acid, but our data does not include effectiveness ratings for CLA. We couldn't check it for drug interactions either. Your pharmacist or doctor can tell you more about its intended use.
Is this safe if I have a sesame allergy?
No. This product contains sesame seed lignan extract, and sesame is a major allergen. Even in concentrated supplements, it can trigger allergic reactions ranging from skin rashes to breathing problems. Do not take this product.
What are the most common side effects of guarana?
The most common are stomach burning and nausea. Because guarana is high in caffeine, it can also cause dizziness, insomnia, nervousness, restlessness, tremors, headache, anxiety, and agitation—especially if you take a large dose.
Can I take this while breastfeeding?
It's best to avoid or limit this product while breastfeeding. Guarana's caffeine passes into breast milk and can affect your baby. Sesame safety while breastfeeding is not well studied in concentrated supplements. Talk with your doctor.
What is sesame seed lignan extract and why is it in here?
Lignan extract is a concentrated form of compounds from sesame seeds. Research shows sesame may help lower blood pressure, which is why it's included. However, it's a major allergen, so it's not suitable for everyone.
