Elite Focus contains naturally occurring amino acid L-Tyrosine which gives your body more of the raw materials to make adrenaline. This works in an all-natural manner to allow your body to make more energy as is needed. Our special blend of herbs and other vitamins help to strengthen and heal your adrenal glands, providing you with energy that lasts all day. There is no artificial caffeine or sugar, meaning the "crash" expected after most energy products won't come.
