Epithalon has been researched for over 40 years with a strong safety profile when used appropriately, working by naturally stimulating your pineal gland to produce more melatonin. It doesn't force sleep artificially but rather helps restore your body's natural circadian rhythm over time. Common side effects are minimal, though as with any supplement, it's important to start with recommended dosages and monitor your response.
