L-CARNITINE INJECTION BENEFITS
The Fat-Burning Molecule in Every Cell
- L-Carnitine is your fat taxi. It physically carries long-chain fatty acids across mitochondrial membranes—without it, your body can't efficiently burn fat for energy.
- Production declines with age. Your body makes less L-Carnitine as you age, which is one reason metabolism slows and fat storage increases over time.
- Oral supplements absorb poorly. Only 5–18% of oral L-Carnitine is absorbed. Injections deliver the full dose directly for immediate bioavailability.
- Your heart runs on it. The heart derives 70% of its energy from fatty acid oxidation—a process that depends on adequate L-Carnitine levels.
- Exercise performance improves. Studies show L-Carnitine supplementation can increase fat oxidation during exercise by up to 55%.
- Dosed for your goals. Your physician calibrates your weekly injection protocol based on your activity level, body composition, and health targets.
