L-Carnitine 200mg Dosage Protocol

Educational guide for reconstitution and administration of L-Carnitine, a nutrient studied for energy metabolism and mitochondrial function.

Quickstart Highlights

L-Carnitine dosage protocols focus on this essential nutrient that serves as a cofactor for fatty acid oxidation and energy production in mitochondria.

  • Reconstitute: Add 2.0 mL bacteriostatic water → 100 mg/mL concentration
  • Typical protocols: 500–2000 mg administered 1-3 times daily (oral/subcutaneous)
  • Easy measuring: At 100 mg/mL, 1 unit = 0.01 mL = 1 mg on a U-100 insulin syringe
  • Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and use within 2–4 weeks

Dosing & Reconstitution Guide

Educational guide for reconstitution and daily dosing

Subcutaneous Protocol (2 mL = 5 mg/mL)

Phase Daily Dose (mg) Units (per injection) (mL)
Weeks 1–4 50 mg once daily 50 units (0.50 mL)
Weeks 5+ 100 mg once daily 100 units (1.0 mL)

Frequency: Inject once or twice daily subcutaneously. Due to the compound's plasma half-life of approximately 3.8–6.9 hours, twice-daily (BID) dosing may provide more sustained NNMT inhibition. Note: A single 10 mg vial provides only 2–4 days of research material at these doses.

Reconstitution Steps

  1. Remove the vial from freezer storage (−20 °C / −4 °F) and allow to equilibrate at room temperature for 15–20 minutes.
  2. Draw 2.0 mL bacteriostatic water with a sterile syringe.
  3. Inject slowly down the vial wall; avoid foaming.
  4. Gently swirl/roll until dissolved—solution should be clear (do not shake).
  5. Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light; use within 2–4 weeks.

Biological Action

L-Carnitine represents an essential nutrient and quaternary ammonium compound that plays a critical role in mitochondrial fatty acid oxidation and energy metabolism.

As a carrier molecule, L-carnitine facilitates the transport of long-chain fatty acids across mitochondrial membranes for beta-oxidation and ATP production. It serves as an essential cofactor in cellular energy metabolism.

L-Carnitine has been extensively studied for its role in supporting mitochondrial function and energy production in research contexts.

Potential Benefits & Side Effects

Findings from metabolic and mitochondrial research.

Injection Technique

General subcutaneous guidance from clinical best-practice resources.

  1. Clean the vial stopper and skin with alcohol; allow to dry.
  2. Pinch a skinfold; insert the needle at 45–90° into subcutaneous tissue.
  3. Do not aspirate for subcutaneous injections; inject slowly and steadily.
  4. Rotate sites systematically (abdomen, thighs, upper arms) to avoid lipohypertrophy.
  5. Slow injection may minimize any stinging sensation associated with the compound.
