HappySense naturally enhances serotonin, which in turn improves mood, reduces cravings and increases energy. Healthy levels of serotonin help to deal with stressors leaving a feeling of relaxation and calm. 5-HTP, the significant ingredient in HappySense, has been clinically shown to be of benefit for fibromyalgia, chronic and migraine headaches, binge eating associated with obesity, and insomnia. 5-HTP has also been extensively researched for the treatment of mood, and other sleep disorders. 5-HTP allows for natural sleep without the drugged feeling of prescription medication in the morning.
