These fast-dissolving melatonin tablets help restore proper sleep patterns and correct problems associated with jet lag. Melatonin is a natural substance secreted by the pineal gland that plays an important role in our sleep cycles. As we age melatonin production decreases often leading to sleep disorders. This product helps maintain the bodys 24 hour circadian rhythm which in turn works to support your immune system by acting as an antioxidant to help protect against cell damaging free radicals. Each tablet is dissolved quickly to allow your body to absorb melatonin quickly for ultimate effectiveness. This product is all-natural non-addictive and is very safe for use.
