Are the Zzzs you need eluding you? Get your sleep-wake schedule back on track with Swanson Extra Strength Melatonin. Each capsule delivers a potent 5 mg melatonin to help restore normal sleep patterns. So what is melatonin? It is a hormone naturally produced by the pineal gland that signals the body when it is time to sleep. Unfortunately that production can be disrupted by multiple factors, including age, travel, shift work and more. Adding a melatonin supplement to your nighttime routine can help support healthy levels in the body so you can get the restorative sleep you need. As an antioxidant, it also works to protect the body from free radicals, notably the eyes where it may offer protection for retinal health. Appropriate melatonin levels have also been tied to healthy cognition and stress management.
