What is levocarnitine, and what is the search really asking?
Both labels describe levocarnitine as a carrier molecule in the transport of long-chain fatty acids across the inner mitochondrial membrane [1][2]. Levocarnitine is the drug name for L-carnitine, the form made in the body, and it is a small molecule rather than a peptide.
A search for levocarnitine usually asks one of three things: what it is, whether the injection and the drink are the same strength, and how many milligrams are in a millilitre. The labels answer all three. They differ in concentration by a factor of two, which is the detail most worth getting right. Searches also mix in acetyl-L-carnitine, a related but different compound; neither label on this page covers it, so it is left out.
What do the levocarnitine labels report?
The injection label covers intravenous use only, for the acute and chronic management of inborn errors of metabolism that cause secondary carnitine deficiency, and for the prevention and management of carnitine deficiency in end stage renal disease on dialysis [1]. It is supplied as 1 g in a 5 mL single-dose vial and 4 g in a 20 mL single-dose vial, both 200 mg/mL, with no preservative.
The oral solution label is for primary systemic carnitine deficiency, and the product is 1 g per 10 mL in 118 mL multiple-dose containers [2]. Its pharmacology section reports that after a slow intravenous bolus about 76% of the amount was excreted in urine within 24 hours, with a terminal elimination half-life of 17.4 hours, uncorrected for the body's own carnitine.
The oral label also reports that tablets and the oral solution were bioequivalent in 15 healthy men, with peak plasma levels about 3.3 hours after the dose [2]. Absorption by mouth is limited. Corrected for endogenous levels, absolute bioavailability was about 15.1% for tablets and 15.9% for the oral solution [2]. The injection label lists transient nausea and vomiting first among adverse reactions [1].

How many mg are in a mL of levocarnitine?
The arithmetic comes straight from the labeled presentations. The injection is 1,000 mg in 5 mL, so 1 mL holds 200 mg; the oral solution is 1,000 mg in 10 mL, so 1 mL holds 100 mg [1][2][4]. The same millilitre therefore carries twice the levocarnitine in the injection as in the drink.
Going the other way, an amount in milligrams divided by the concentration gives the volume: 500 mg is 2.5 mL of the injection or 5 mL of the oral solution [4]. The injection label also lists dilution in saline or lactated Ringer's from 0.5 to 8 mg/mL for infusion, which is a different solution again [1]. Neither product is an insulin-syringe solution, so the peptide calculator is a cross-check here, not a preparation tool.
How do people log levocarnitine in PinPoint?
PinPoint's compound library has no levocarnitine entry [3]. The app's library spans peptides, TRT and GLP-1 medicines, with longevity and ancillary compounds such as NAD+, across injection, oral, nasal, topical and sublingual routes, and the peptide library lists every compound with a guide [5].
For library compounds, vial setup takes a size in mg, mcg or IU with a liquid volume and shows the concentration [5]. Entries record compound, dose, site and pain level, with reminders at the day and time set, and the history exports as PDF, CSV or JSON [5]. Weight, calories, protein and water can be logged alongside, with trend charts, and Apple Health sync covers weight, water, nutrition and activity [5].

- What is levocarnitine?
- Levocarnitine is the drug name for L-carnitine, a carrier molecule that moves long-chain fatty acids into mitochondria. It has FDA labels as an injection and an oral solution.
- Is levocarnitine the same as L-carnitine?
- Yes. Levocarnitine is the L-isomer of carnitine, the form made in the body. Labeled products state their strength as levocarnitine.
- How many mg are in 1 mL of levocarnitine injection?
- The cited injection label lists 1 g in 5 mL and 4 g in 20 mL, which is 200 mg per mL. The oral solution is 100 mg per mL.
- How much oral levocarnitine is absorbed?
- The oral solution label reports absolute bioavailability of about 15.9% for the solution and 15.1% for tablets, corrected for the body's own carnitine.
