— The science
How L-Carnitine Injection works, and what the research shows.
— How it works
L-carnitine carries fat into the cell's mitochondria to be burned for energy.
As an injection it skips the poor absorption that limits carnitine supplements.
— Clinical evidence
Injectable L-carnitine has decades of clinical use for carnitine deficiency.
Studies in exercise and metabolism report modest gains in fat burning and recovery.
