L-carnitine is an amino-acid essential to oxidative metabolism of fatty acids.

It becomes synthesized in liver from L-Methionine and L-Lysine.

It is recommended for athlete horses because it improves muscular adaptability to training. (Rivero et al 2002), it increases resistance to strain, improves regeneration of hosphocreatine (molecule rich in energy) and of glycogen while at the same time decreasing recovering time.

L-Carnitine also improves mare fertility by improving sperm quality (motility) of the stallions. (Stradaioli and al 2004).

A mare provided with L-Carnitine will meet essential requirements of the foal via milk (Benamou et Harris 1993).
