Are you one of the 40 million people in america who don't get enough sleep each night? If so, the effects may extend beyond just leaving you feeling tired during the day. Getting too little sleep can impact your health in some surprising ways, leading to a weaker immune system, irritability, lower productivity, and it can even impact your weight and food choices since you may be more likely to reach for sugary, high-carb snacks as a quick-fix for low energy levels. The good news is, there's a better way--say goodbye to restless nights with the help of an innovative sleep supplement featuring carefully curated, science-backed ingredients that are non-habit forming and work together to supports rest and relaxation. Swanson's comprehensive sleep formula delivers a powerful trio of studied relaxation and sleep-supporting ingredients--Melatonin, gaba and valerian root--in a unique tri-layer tablet to allow immediate and delayed release of these nutrients to help you get the rest you deserve. Here's how our high quality ingredients work, and why tri-layer tabs make a difference. Melatonin for sleep Melatonin is a hormone that signals your body when it's time to rest, but age and other factors, such as a disrupted sleep schedule or too much screen time before bed, can cause your body to make less Melatonin than it should. Supplementing with Melatonin can help get your sleep schedule back on track--but not all Melatonin supplements are created equal. Our comprehensive sleep formula delivers 10 mg of Melatonin in stages, releasing 5 mg of Melatonin initially, followed by another 5 mg throughout the night to more closely mimic your body's natural Melatonin production. Gamma-aminobutyric acid (gaba) for relaxation gaba is a neurotransmitter that plays an important role in calming activity in the nervous system. What does that have to do with sleep? If you've ever lain awake in bed with your mind racing, low gaba may be to blame. Studies have linked gaba supplements to better sleep and less stress, making it the perfect partner for Melatonin.
