Animal models suggest that L-Carnitine improves the quality of ovary cells and embryos, improves hormone levels, and increases the weight of reproductive organs. The antioxidant and cell-protective effects, as well as energy producing effects, of L-Carnitine are thought to be at least partially responsible for fertility benefits. L-Carnitine might also indirectly promote fertility by improving hormone release from the hypothalamus. Furthermore, L-Carnitine protects against hypertension-induced cardiac reshaping and related inflammation and also reduces symptoms of hyperthyroidism.
