Human dosing

LC600 (L-carnitine) dosing in research protocols depends on the route of administration: the table below lists the intramuscular regimen from a clinical study separately from the intravenous doses in the FDA label.

Period / conditionDoseSource
IM, course500 mg intramuscular twice daily for 7 days; second course after 10 daysChichanovskaya et al., 2017 (post-stroke rehabilitation)
IV, hemodialysis10–20 mg/kg dry body weight after each dialysis session, starting doseFDA label (Carnitor)
IV, metabolic disorders50 mg/kg/day; highest dose given 300 mg/kgFDA label (Carnitor)

Background on the molecule, its mechanism and primary sources is covered in the monograph.

Practical dosing and effect details

L-carnitine (levocarnitine) is one of the few compounds on this site with an established clinical history: Flanagan and colleagues (Nutrition & Metabolism, 2010) reviewed the literature on carnitine's role in deficiency states, from uremia to metabolic disorders. The route of administration affects the dose needed: the FDA label puts the absolute bioavailability of oral levocarnitine at only about 15%, so oral regimens (typically 1–3 g/day in studies, see the monograph) do not carry over to injections, or the other way round.

The roughly 50 mg/kg per day figure for IV use in the table above applies specifically to the intravenous route; that does not mean the same dose fits a research protocol built around a different route. The 600 in the LC600 name is the vial content, 600 mg of lyophilized L-carnitine, not a solution concentration. The concentration depends on the volume of diluent used to reconstitute the vial.

This is reference information for planning a research protocol, not a medical recommendation and not instructions for self-administration.

How to reconstitute

An example reconstitution for convenient dosing. The exact ratios depend on your vial. For research reference only — not medical guidance.

  1. 1Add the diluentUse bacteriostatic water. Example: 6 ml into a 600 mg vial.L-Carnitine600 mg+ 6 mlDiluent
  2. 2Get the concentrationExample: 600 mg in 6 ml =L-Carnitine100 mg/ml(100,000 mcg/ml)
  3. 3Work out the volume per doseFor example, for a 150 mg dose:150 mg = 1.5 ml= 150 u. (U-100)

This is only an example calculation. You can use a different diluent volume — plug your own numbers into the calculator. Open calculator →

Notes and safety

  • • L-Carnitine is a research peptide. Human safety and efficacy data are limited.
  • • The regimens shown are based on publications and research protocols, not clinical recommendations.
  • • Individual reactions may vary. Published protocols typically start dosing at the lower end of the reported range.
  • • Not recommended for use with chronic illness, pregnancy, or breastfeeding.
