Elderly people have a lower energy demand and eating habits change with age. For example, they usually consume less meat. At the same time, the dietary intake of both L-Carnitine and the nutrients required to make L-Carnitine is reduced. A decreased endogenous synthesis could also be shown by researchers. A decrease of L-Carnitine in various body compartments with age has often been described in literature. The resulting reduction in energy metabolism due to lower L-Carnitine levels can be restored by L-Carnitine supplementation.
