Save money on our best supplements for promoting healthy sleep with our Sleep Stack! This combo deal includes one bottle of L-Theanine, one bottle of Apigenin, and one bottle of Magnesium Threonate. Magnesium Threonate is one of the most effective supplements for sleep as it can cross the blood-brain barrier and deposit magnesium directly in the brain. This means unlike other magnesium supplements which circulate their magnesium throughout the body, most of the magnesium it provides will be transported to the brain where it can regulate neurotransmitters responsible for sleep. L-Theanine is another effective supplement for sleep and works by helping to regulate the GABA system as well as promoting feelings of relaxation, but does so without acting as a sedative. Apigenin is a bioflavonoid and antioxidant compound which is found in many different plants and herbs but is especially abundant in chamomile tea, it provides the sleep enhancing effects provided from chamomile tea.
