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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This liquid contains 4 active ingredients working together. Vitamin B12 helps your body use energy and keep your nervous system healthy.

L-carnitine, the main ingredient at 1500 mg per serving, helps your cells produce energy from fats. Vitamin B1 and Vitamin B5 are also B vitamins that support energy metabolism.

The product is a blue raspberry flavored liquid with inactive ingredients like citric acid, malic acid, and FD&C Blue #1 for taste and color.

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: Boost energy, endurance and exercise performance.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Exercise-induced muscle soreness, Fatigue, L-carnitine deficiency, Muscular endurance — and 2 related terms.
  • The strongest evidence on file: L-carnitine is rated "Effective" for L-carnitine deficiency (Natural Medicines).
  • Also on file: Vitamin B12 is rated "Insufficient Reliable Evidence To Rate" for Fatigue.
  • Also on file: L-carnitine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Cancer-related fatigue, Chemotherapy-related fatigue, Chronic fatigue syndrome (CFS), and more.

L-carnitine is effective for treating L-carnitine deficiency and possibly effective for high cholesterol, congestive heart failure, and angina. Vitamin B12 is effective for treating B12 deficiency and Imerslund-Grasbeck disease, possibly effective for canker sores and nerve pain after shingles, and likely effective for cyanide poisoning.

The evidence we hold doesn't establish effectiveness for Vitamin B1 or Vitamin B5 in this product.

The evidence, ingredient by ingredient Vitamin B12 L-carnitine

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, though high doses can cause stomach upset and a fishy body odor. Common side effects include abdominal cramps, nausea, diarrhea, and heartburn.

Seizures have been reported rarely. Vitamin B12 is very safe — your body excretes excess B12 in your urine, so there's no established upper limit.

It's needed in pregnancy and safe at normal recommended amounts, and it's important during breastfeeding at recommended amounts. For L-carnitine, there isn't enough safety data in pregnancy, so use only under medical supervision if pregnant.

Safety while breastfeeding hasn't been well studied, so caution is advised.

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 — Vitamin B12, L-carnitine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 39 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 start, check if you take any blood thinners (Moderate risk — warfarin and acenocoumarol especially), thyroid hormone replacement therapy (Moderate risk), or metformin for diabetes (Minor risk). These are the medication types documented to interact with ingredients in this product.

The bottom line

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

This product is worth considering if you're looking to support energy production or treating a documented L-carnitine or B12 deficiency. If you take blood thinners like warfarin, thyroid medication, or metformin for diabetes, talk with your pharmacist before starting — those interactions need a closer look at your exact situation.

Formula

Delicious and easy-to-take liquid L-Carnitine with 1500 mg in just 1 serving! Boost energy, endurance & performance. L-Carnitine enhances performance by increasing the body's reliance on fat for energy; this reduces depletion of muscle glycogen. By reducing muscle tissue lactic acid build-up, performance athletes using L-Carnitine can extend duration of muscular exertion before fatigue. Added Vitamin B5 makes L-Carnitine work better by helping it shuttle fatty acids to the cell to be burned for energy production.

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.

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.

Liquid L-Carnitine 1500 Blue Raspberry by ALLMAX ESSENTIALS: Common Questions

Does Liquid L-Carnitine 1500 Blue Raspberry by ALLMAX ESSENTIALS interact with any medications?
Yes. Based on its ingredients, Liquid L-Carnitine 1500 Blue Raspberry has a known interaction with 39 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Liquid L-Carnitine 1500 Blue Raspberry 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.
Is this safe if I'm pregnant or breastfeeding?
Vitamin B12 in this product is considered safe in pregnancy and breastfeeding at normal recommended amounts — in fact, it's needed during both. However, L-carnitine doesn't have enough safety data in pregnancy, so you'd need to use it only under medical supervision. L-carnitine safety while breastfeeding also hasn't been well studied, so caution is advised. Talk with your doctor or pharmacist about your personal situation before starting.
What are the most common side effects?
L-carnitine can cause stomach upset — abdominal cramps, nausea, diarrhea, and heartburn are the most common. Some people also report a fishy body odor with higher doses. Vitamin B12 is very well tolerated and rarely causes side effects orally. If you get injection site reactions (if you were taking B12 by injection), those would be the most common, but this is a liquid supplement.
Will this help my cholesterol or heart problems?
L-carnitine is possibly effective for high cholesterol, congestive heart failure, and angina based on the evidence we hold. That means there's some support for it, but it's not yet proven enough to call it definite. Talk with your doctor about whether it might be right for your specific condition.
Can I take this if I'm on warfarin or another blood thinner?
No — not without checking with your pharmacist or doctor first. L-carnitine may increase how well blood thinners like warfarin and acenocoumarol work, which could make your blood thinner than your doctor intends. That's a Moderate severity interaction, so this needs personalized review before you start.
What does L-carnitine actually do?
L-carnitine helps your cells produce energy from fats. It's especially useful if you have a documented L-carnitine deficiency. It's also being studied for heart and cholesterol support, though those benefits are still being confirmed.
I'm on metformin for diabetes — is this okay?
There's a Minor interaction: metformin can lower your B12 levels over time, and this product adds B12 back. It's not a major concern, but let your pharmacist know so they can monitor your B12 status if needed, especially if you've been on metformin for a while.
