Inside the product: Zinc is important for regulating the sleep portion of the circadian rhythm, as well as improving general sleep. Zinc methionine provides the body with zinc in a form that aids the body in absorbing it. Similar to zinc methionine, magnesium in the form of magnesium bisglycinate allows the body to better absorb the nutrient. Magnesium plays a crucial role in sleep by helping to maintain healthy levels of GABA, a neurotransmitter that promotes sleep. P-5-P is the active form of vitamin B6 in the body, and helps to support sleeping and waking cycles. L-Theanines role in the sleep stack is to promote relaxation and facilitate sleep by contributing to changes in your brain waves which lower levels of excitatory brain chemicals. 5-HTP aids in the production of serotonin, which in turn can be converted to melatonin, a crucial chemical for regulating sleep. Vitamin B5 plays an important role in relaxing muscles and easing tension in the body.
