Be Happy…. Not SAD

Low moods and wintertime in Canada often go hand in hand. Reduced sunlight can cause a drop in serotonin which in turn may trigger low moods or other symptoms of low serotonin. This occurs more commonly among people who live far south or far north of the equator – as we do in Canada. In November you may notice your energy levels, sleep, cravings and moods are on a downward trend as a result of low serotonin levels.

Low serotonin levels, one of our brain hormones, are often associated with sleeping disorders, however, low serotonin levels can also cause many other symptoms including:

  • Fatigue
  • Moodiness
  • Chronic pain
  • Cravings
  • Anxiety
  • Disrupted sleep cycles
  • Poor concentration
  • Mild depression

When serotonin levels are raised we feel well-balanced emotionally and sleep more soundly. We also have fewer cravings. Serotonin helps relay the message to your brain when you are full. When serotonin levels are low, it leads to overeating and cravings.

5-HTP raises serotonin, and serotonin signals your brain that you are full and should stop eating. When obese women who overate carbohydrates took 5-HTP or a placebo twenty minutes before meals in a double-blind study, their caloric intake went down by 37%, and they lost three pounds in five weeks even though they were not exercising and ate whatever they wanted. Though their before meal appetite was not affected, they felt full faster after eating (1). When 5-HTP or a placebo was given to obese women half an hour before meals in a double-blind study, the placebo group lost 2.28 pounds in six weeks, but the 5-HTP group lost 10.34. As in the previous study, the women reported that they felt full faster (2).

How can we raise serotonin levels naturally?

HappySense®, with 5-HTP, naturally enhances serotonin, which in turn improves mood, reduces cravings, promotes sounder sleep and reduces the severity of migraines. Healthy levels of serotonin help to deal with stressors leaving a feeling of relaxation and calm. 5-HTP, as found in HappySense, allows for natural sleep without the drugged feeling of prescription medication in the morning. HappySense is also effective in the relief of fibromyalgia symptoms.
