L-carnitine has shown promise as a potential treatment for insulin resistance and type 2 diabetes. Clinical studies have demonstrated its efficacy in improving glycemic control and lipid profiles in patients with type 2 diabetes. The mechanisms of action of L-carnitine in the treatment of type 2 diabetes are not fully understood, but it is believed to improve mitochondrial function, reduce oxidative stress, and improve lipid metabolism. Further research is needed to fully elucidate the potential of L-carnitine in the treatment of insulin resistance and type 2 diabetes.
