Brand: Source Naturals Sleep Science
Dr. Feb's Analysis
Scientific Mechanism
The primary active ingredient, Melatonin, is a neurohormone naturally produced by the pineal gland. It functions as a potent chronobiotic, binding to MT1 and MT2 receptors in the suprachiasmatic nucleus (SCN) of the brain. This interaction inhibits neural activity, signaling to the body that it is time to sleep, thereby regulating the circadian rhythm. The inclusion of Vitamin B6 acts as a vital cofactor in the biosynthesis of neurotransmitters like serotonin, which is a precursor to melatonin, potentially enhancing the supplement's overall efficacy in promoting restful sleep.
Key Benefits
Key benefits include:
- Helps regulate the sleep-wake cycle (circadian rhythm)
- Reduces time to fall asleep (sleep latency)
- Supports restful sleep quality without morning grogginess
- Ideal for travelers combating jet lag
Usage & Safety
Best practices include taking one lozenge 30 to 60 minutes before bedtime. Do not exceed the recommended dosage. As this is a 5mg dose, which is higher than the body naturally produces, start with half a lozenge if you are sensitive to supplements. Do not use with alcohol or while operating machinery. Consult a physician if you have autoimmune diseases, diabetes, or are taking blood thinners.
