Solgar proudly introduces Sweetest Dreams Vegetable Capsules. Each vegetable capsule offers 3 mg of melatonin (as n-Acetyl-5-Methoxytryptamine) and 100 mg of L-theanine (Suntheanine). This synergistic formula is designed for people experiencing occasional sleeplessness, those with jet lag, or anyone wanting to promote a restful, relaxed state. Melatonin is a hormone naturally secreted by the pineal gland in the brain. The pineal gland processes information about light and dark and relays it to cells throughout the body. Its high lipophilicity, or fat solubility, allows it to transmit the signal of darkness to every cell in the body, acting as the eyes for each cell, organ, and tissue. This is why melatonin levels throughout the body are so important for promoting calm, restful sleep and a relaxed mood in the evening by supporting natural circadian rhythms. Studies support melatonin's positive role in promoting sleep. Research also suggests that melatonin may help support those experiencing jet lag.L-theanine is a nonessential amino acid commonly found in green tea that can support the mood centers in the brain. L-theanine enhances alpha brain wave activity, which is considered indicative of relaxation. Studies support L-theanine's positive effects on relaxation and mood support.
