Why inject L-Carnitine instead of taking it orally?

Oral L-carnitine has only 5-18% bioavailability, and gut bacteria convert much of it to TMAO (a potential cardiovascular risk factor). SC injection achieves ~100% bioavailability, avoids TMAO production, and reliably increases muscle carnitine stores.

Will L-Carnitine help me lose fat?

L-Carnitine facilitates fat transport into mitochondria but does not directly cause fat loss. It enhances the body ability to USE fat as fuel, particularly during exercise. Without a caloric deficit and physical activity, carnitine alone will not produce significant fat loss.

What is the recommended dose range for L-Carnitine (Injectable)?

The research dose range is 50-200 mg per injection, administered via Subcutaneous injection, Once daily.
