Neurotransmitters are chemicals used to transmit signals throughout the body. Many of these neurotransmitters originate in the brain and cascade through the endocrine system, sending hormones to the muscles and other fibers of the body. As a result, almost no function of the mind and body can occur without these neurotransmitters. fUS introduces a unique blend of amino acids that facilitate the function of neurotransmitters. Independent clinical studies have shown that these amino acids can help promote the functions of the mind and body, giving one a sense of energy, mental well being, physical strength and endurance.
