InVite Health, New Hyde Park, NY, has released Power Plant Sleep Awake, a sleep enhancement dietary supplement. A specially designed capsule ensures the quick release of two nutrients that foster deep, refreshing sleep: L-theanine, an ingredient from the tea plant known for its relaxing effects, and also melatonin, a nutrient produced by the body for sleep. These two ingredients are released immediately to help induce sleep and hours later a coffee cup’s worth of caffeine is slowly released allowing users to gently wake up feeling fresh and alert, according to the company.
