HelloPharmacist Scorecard of CarnitALL by Jarrow Formulas

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 8 of its 8 active ingredients.
  • “Acetyl-L-Carnitine Arginate Dihydrochloride” is listed as a grouped ingredient — the label gives one combined amount (200 mg) without saying how much of each component you get.
  • “L-Carnitine Fumarate” is listed as a grouped ingredient — the label gives one combined amount (600 mg) without saying how much of each component you get.
  • “Acetyl-L-Carnitine Taurinate Hydrochloride” is listed as a grouped ingredient — the label gives one combined amount (200 mg) without saying how much of each component you get.

CarnitALL contains eight active ingredients focused on energy production and heart and brain health. The main players are three forms of carnitine — L-carnitine, acetyl-L-carnitine, and propionyl-L-carnitine — along with glycine, taurine, and arginine.

Carnitines help your cells convert fat into energy; the different forms are absorbed and used slightly differently. Glycine and taurine are amino acids your body makes naturally.

Arginine is another amino acid that supports circulation and immune function. The product also contains inactive ingredients — cellulose, silicon dioxide, magnesium stearate, and the capsule itself — which are binders and fillers that hold everything together.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: carnitine support for cardiac and mitochondrial function.
  • We looked for evidence on: Age-related cognitive decline, Angina, Arrhythmia, Athletic performance, Atrial fibrillation, Cardiovascular disease (CVD) — and 4 related terms.
  • The strongest evidence on file: Propionyl-l-carnitine is rated "Possibly Effective" for Angina (Natural Medicines).
  • Also on file: Propionyl-l-carnitine is rated "Possibly Effective" for Cardiovascular disease (CVD), Congestive heart failure (CHF).
  • Also on file: Acetyl-l-carnitine is rated "Possibly Effective" for Age-related cognitive decline, Diabetic neuropathy.

The evidence for what CarnitALL can do is mixed and mostly modest. Acetyl-L-carnitine is rated possibly effective for age-related memory loss, Alzheimer's disease, depression, and diabetic nerve pain.

L-carnitine shows possibly effective evidence for heart failure, angina, and high cholesterol, and is rated effective for actual L-carnitine deficiency (a rare condition). Propionyl-L-carnitine is possibly effective for heart failure, angina, and cardiovascular disease.

Taurine is possibly effective for hepatitis and heart failure, but possibly ineffective for weight loss. Glycine is possibly effective for schizophrenia when added to clozapine — though our interaction data warns it may worsen symptoms in some patients.

For the other conditions listed, the evidence isn't established in our data.

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of CarnitALL's ingredients are generally well tolerated short-term, but long-term safety data are limited or not fully established. Common side effects include nausea, diarrhea, headache, dry mouth, and insomnia.

Some forms of carnitine can cause a fishy odor in urine, breath, and sweat. Rare side effects of glycine include mild sedation and memory impairment; rare side effects of taurine include hypersensitivity reactions in people with sulfa or sulfite allergies.

For pregnancy, the data we hold shows insufficient information for most ingredients — there isn't enough reliable information to know whether it's safe, so talk with your doctor or pharmacist. For breastfeeding, acetyl-L-carnitine and propionyl-L-carnitine data advise against use, taurine is rated likely safe, L-carnitine is rated possibly safe, and glycine data advise caution.

We hold no pregnancy or breastfeeding data for arginine hydrochloride and fumaric acid.

Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 5 of the 5 matched ingredients can interact with medications — Propionyl-l-carnitine, Acetyl-l-carnitine, Taurine, L-carnitine, Glycine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 375 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 CarnitALL, double-check if you're on clozapine (Clozaril), blood thinners like warfarin or acenocoumarol, thyroid hormone replacement, serotonergic antidepressants or migraine drugs, blood pressure medications, or lithium. The carnitine ingredients and taurine have Moderate interactions with most of these drug types.

If you take any of these, run them through the interaction checker on this page or ask your pharmacist.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you take clozapine, blood thinners, thyroid hormone, a serotonergic antidepressant, blood pressure medication, or lithium, you need to check with your pharmacist before starting this product. Otherwise, if you're interested in the energy or cognitive benefits, the carnitine forms and taurine are generally tolerated, though long-term safety isn't fully proven.

Acetyl-L-Carnitine Arginate Dihydrochloride4 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.

L-Carnitine Fumarate3 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.

Acenocoumarol (Sintrom)

Theoretically, propionyl-L-carnitine might increase the anticoagulant effects of acenocoumarol.
L-carnitine, the parent compound of propionyl-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 when L-carnitine was taken with acenocoumarol.

Likelihood Possible Evidence D

Glycine1 drug type · 1 drug

Clozapine (Clozaril)

Theoretically, glycine might decrease the effectiveness of clozapine.
One small clinical study in patients with schizophrenia shows that adding glycine to clozapine therapy worsens symptoms of schizophrenia when compared with clozapine alone. The mechanism of this interaction is unclear.

CarnitALL by Jarrow Formulas: Common Questions

Does CarnitALL by Jarrow Formulas interact with any medications?
Yes. Based on its ingredients, CarnitALL has a known interaction with 375 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
CarnitALL contains 5 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 CarnitALL if I'm pregnant?
The safety data we hold doesn't establish whether it's safe in pregnancy — there isn't enough reliable information. Talk with your doctor or pharmacist for personalized advice before you start.
Is it safe while I'm breastfeeding?
It depends on the ingredient. L-carnitine is rated possibly safe, and taurine is rated likely safe, but acetyl-L-carnitine and propionyl-L-carnitine should be avoided. We don't have safety data for arginine or fumaric acid. Check with your pharmacist or doctor for guidance specific to your situation.
What is acetyl-L-carnitine supposed to do?
Acetyl-L-carnitine is possibly effective for age-related memory loss, Alzheimer's disease, depression, and diabetic nerve pain. It's a form of carnitine that's absorbed differently and may cross into the brain more easily than regular L-carnitine.
Can CarnitALL help with weight loss?
Taurine, one of the ingredients, is rated possibly ineffective for weight loss according to our data. The carnitines have not been rated for weight loss in our data.
What side effects might I experience?
Common ones are nausea, diarrhea, headache, dry mouth, and insomnia. Some people report a fishy odor in their urine, breath, or sweat. Rare side effects include memory problems or mild sedation. Most side effects ease or go away if you stop taking it.
Does CarnitALL have any fillers?
Yes, it has inactive ingredients: cellulose, silicon dioxide, magnesium stearate, and the capsule. These are standard binders and fillers that help hold the active ingredients together.
