Zenbev is a delicious beverage mix that provides a natural source of tryptophan, derived from pumpkin seeds, to alleviate anxiety, stress and insomnia. Zenbev® Drink mix is an organic sleep aid made from pumpkin seeds. The organic pumpkin seeds are cold pressed to remove the oil and blended in a powder formulation which is clinically proven to promote sleep naturally. Zenbev can be taken during the day to provide a powerful source of tryptophan, a precursor for serotonin. Serotonin regulates mood, emotion and appetite, and is well-known to alleviate stress, anxiety and depression. Other purported benefits of ingesting a natural source of tryptophan include easing chronic pain symptoms, weight loss and increased libido. Tryptophan is light sensitive, meaning it metabolizes differently in light vs. dark conditions. When taken during daylight hours Zenbev's tryptophan becomes serotonin providing the aforementioned benefits. If taken at night, Zenbev's tryptophan turns into serotonin, which then metabolizes into melatonin, thus activating the brain's own sleep mechanism. As the brain produces the exact amount of melatonin that it requires, the body is primed for a natural, restful sleep.
