Enervite’s Sleep Enhance’s fast-acting formula is designed to help prepare your body and mind enter into a calm, relaxed state where sleep comes easily and naturally. It is a premium natural formula utilising the best ingredients and new science of western medicine. Its inclusion of the key ingredient Kava sets it aside from many other products on the market. It has also taken advantage of recent discoveries in the labs such as including both Valerian and Hops together, which has been proven more effective than the ingredients when used separately.
