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 6 of its 10 active ingredients.
  • “CarniTone 3000 Advanced L-Carnitine Complex” is a proprietary blend — the label gives one combined amount (1.50 Gram(s)) without saying how much of each component you get.
  • “CarnEnergy Advanced Energy Matrix” is a proprietary blend — the label gives one combined amount (125 mg) without saying how much of each component you get.
  • “Energy Matrix” is a proprietary blend — the label doesn't break down how much of each component you get.

L-Carnitine LS3 + Energy contains 10 active ingredients designed to support energy and athletic performance. The product includes multiple forms of L-carnitine—L-carnitine itself, acetyl-L-carnitine, and L-carnitine L-tartrate—along with B vitamins (B6 and B12), taurine, and L-ornithine hydrochloride.

It also contains caffeine (in both standard and anhydrous forms) and green tea extract for additional energy support. The remaining ingredients are inactive—purified water, phosphoric acid, citric acid, natural flavor, sucralose, potassium sorbate, acesulfame potassium, and sodium benzoate—which serve as fillers, preservatives, and flavorings.

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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: fat loss and energy support.
  • We looked for evidence on: Athletic performance, Cancer-related fatigue, metabolism, mental alertness, fatigue.
  • The strongest evidence on file: Caffeine is rated "Likely Effective" for Athletic performance (Natural Medicines).
  • Also on file: Caffeine is rated "Likely Effective" for Mental alertness.
  • Also on file: Ornithine is rated "Possibly Effective" for Athletic performance.

Evidence for this product's ingredients is mixed. Vitamin B6 is effective for B6 deficiency and sideroblastic anemia, and possibly effective for pregnancy-related nausea.

Vitamin B12 is effective for B12 deficiency. L-carnitine is effective for carnitine deficiency and possibly effective for heart failure and high cholesterol.

Caffeine is effective for mental alertness and athletic performance. Taurine and acetyl-L-carnitine are possibly effective for heart failure and cognitive decline, respectively.

L-ornithine lacks established evidence in our data—the few studies available show insufficient data to rate it. Green tea extract is likely effective for HPV-related conditions and possibly effective for cholesterol.

The product's overall effectiveness for energy and athletic performance rests mainly on caffeine and the clinical evidence behind its L-carnitine content, though individual results vary.

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 7 of the 8 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 8 of 8.
  • General safety write-ups exist for 8 of 8.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B6 is well tolerated at normal doses but can damage nerves (sensory neuropathy) at very high doses over time—the risk is highest with daily doses over 1,000 mg or total lifetime doses of 1,000 grams or more, though nerve damage can occur at lower amounts. Vitamin B12 is very safe with no established upper limit.

Taurine is generally well tolerated short-term in healthy adults, though long-term safety is less certain; it can cause constipation, diarrhea, or stomach upset. L-carnitine often causes stomach discomfort, nausea, diarrhea, and a fishy body odor at higher doses.

Caffeine in moderate amounts is safe for healthy adults but can cause anxiety, insomnia, tremors, and stomach irritation; high doses may rarely cause stroke. Green tea extract is generally safe but concentrated extracts at high doses have rarely caused liver injury.

L-ornithine's long-term safety isn't well studied. For pregnancy, vitamin B6 is likely safe but possibly unsafe depending on dose—discuss safe limits with your doctor.

Vitamin B12 is safe in pregnancy. Caffeine is possibly safe at moderate levels but possibly unsafe at high levels—your doctor should advise on safe intake.

Green tea is possibly safe in pregnancy at moderate caffeine levels. Lactation data shows B12 is safe; caffeine passes into breast milk in small amounts (moderate intake usually acceptable); L-carnitine, taurine, and acetyl-L-carnitine safety while breastfeeding is either possibly safe or not well studied, so caution is advised.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

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

Why this rating?
  • 7 of the 8 matched ingredients can interact with medications — Acetyl-l-carnitine, Vitamin B12, Vitamin B6, Green Tea, Caffeine, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium; Parkinson's medications.
  • For scale: 1,420 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 or doctor before taking this if you use ephedrine or are about to—the caffeine and green tea can cause dangerous stimulant overload. If you take nadolol or atorvastatin, green tea extract may significantly reduce their effectiveness.

Seizure medications (phenobarbital, phenytoin, carbamazepine, valproate, felbamate, or ethosuximide), blood thinners (warfarin or acenocoumarol), blood pressure medications, thyroid hormones, clozapine (antipsychotic), metformin (diabetes), dipyridamole (stress-test drug), cimetidine (heartburn), quinolone antibiotics, pentobarbital (sedative), lithium, or amiodarone (heart rhythm) all have documented interactions with one or more ingredients. Review your medication list with your pharmacist before starting.

The bottom line

Scorecard at a glancePartially disclosed formula with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This is an energy supplement designed for athletic performance, combining L-carnitine, B vitamins, caffeine, and herbal extracts. If you take any prescription medications—especially blood pressure drugs, seizure medications, blood thinners, heart rhythm drugs, diabetes medications, or antipsychotics—check with your doctor or pharmacist before starting, because several ingredients may weaken or amplify those drugs.

Pregnant or breastfeeding individuals should discuss caffeine and L-carnitine safety with their healthcare provider. For healthy people not on medications, it's generally well tolerated, though expect possible stomach upset, insomnia, jitteriness, and a fishy odor at typical doses.

Vitamin B65 drug types · 210 drugs

Amiodarone (Cordarone)

Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Levodopa

Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.

Likelihood Unlikely Evidence D
Vitamin B6 full monograph & interactions

Acetyl-L-Carnitine4 drug types · 203 drugs

Acenocoumarol (Sintrom)

Theoretically, acetyl-L-carnitine might increase the anticoagulant effects of acenocoumarol.
L-carnitine, the parent compound of acetyl-L-carnitine, might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant that is similar to warfarin, but shorter-acting. There are at least two case reports of INR elevation when L-carnitine was taken with acenocoumarol. 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. It is unclear if such an interaction would also occur with acetyl-L-carnitine.

Likelihood Possible Evidence D
Serotonergic Drugs

Theoretically, acetyl-L-carnitine might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders, when taken with serotonergic drugs.
Animal research shows that acetyl-L-carnitine can increase levels of serotonin in the brain.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, acetyl-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. It is unclear if such an interaction would occur with acetyl-L-carnitine.

Likelihood Probable Evidence B
Warfarin (Coumadin)

Theoretically, acetyl-L-carnitine might increase the anticoagulant effects of warfarin.
L-carnitine, the parent compound of acetyl-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 acetyl-L-carnitine and warfarin.

Likelihood Possible Evidence D
Acetyl-L-Carnitine full monograph & interactions

Vitamin B121 drug type · 20 drugs

Metformin (Glucophage)

Metformin, a common medication used to manage type 2 diabetes, has been associated with lower vitamin B12 levels in some individuals. Prolonged use of metformin can interfere with the absorption of B12 in the digestive system, potentially leading to a deficiency in this essential vitamin.

Likelihood Possible Evidence A
Vitamin B12 full monograph & interactions

L-Carnitine3 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.

L-Carnitine LS3 + Energy Peach Mango by iSatori: Common Questions

Does L-Carnitine LS3 + Energy Peach Mango by iSatori interact with any medications?
Yes. Based on its ingredients, L-Carnitine LS3 + Energy Peach Mango has a known interaction with 1,425 medications, including 13 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
L-Carnitine LS3 + Energy Peach Mango 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.
Can I take this if I'm pregnant?
It depends on which ingredients and doses concern you. Vitamin B6 is likely safe at normal levels but possibly unsafe at high doses—vitamin B12 is safe. Caffeine is possibly safe at moderate intake but possibly unsafe at high amounts. Green tea is possibly safe at moderate caffeine levels. Talk with your doctor or pharmacist to confirm what's safe for your pregnancy and which ingredients to limit or avoid.
Will this keep me awake?
Yes, likely. This product contains caffeine in two forms (caffeine and caffeine anhydrous), as well as green tea extract, which also contains caffeine. Caffeine commonly causes insomnia and restlessness, especially if you take it late in the day or are sensitive to stimulants.
What's L-carnitine supposed to do?
L-carnitine is effective for carnitine deficiency and possibly effective for heart failure, chest pain (angina), and high cholesterol. In this product, it's one of three carnitine forms included to support energy and athletic performance, though the evidence is strongest for the deficiency and heart conditions listed.
Can I take this while breastfeeding?
Caffeine passes into breast milk in small amounts—moderate intake is usually considered acceptable, but high amounts may affect the baby. Vitamin B12 is safe while breastfeeding. L-carnitine, taurine, and acetyl-L-carnitine safety during breastfeeding is either possibly safe or not well studied, so talk with your doctor or pharmacist about whether this product is right for you.
What side effects might I get?
Common ones include stomach cramps, nausea, diarrhea, and heartburn from the L-carnitine and taurine. Caffeine often causes anxiety, tremors, jitteriness, headache, and insomnia. A fishy body odor has been reported with higher doses of L-carnitine. These usually improve if you lower the dose or stop taking it.
Why does this have green coffee bean extract listed?
The product facts show green coffee bean extract is part of a blend (the 'Energy Matrix' group ingredient), so its individual components aren't separately listed here. We have no separate interaction or effectiveness data on file for it.
