Shield is designed to promote nerve health and function. It can be used to help maintain healthy nerves by supplying the body with Vitamin B complex, Alpha Lipoic Acid, and Acetyl L-carnitine. Support With B Vitamins Vitamins B1, B6, and B12 all play a vital role in nerve synthesis and signaling. Without ample Vitamin B, nerves may not perform optimally. Shield is dosed with your daily needs in one serving. Recover With Acetyl-L-Carnitine Acetyl-l-carnitine (ALCAR) helps transport lipids to the nerves. Lipids make up the structure and the domain of energy supply for nerve function. Simply put, ALCAR helps provide the nutrients needed for overall nerve health.
