Please note | Melatonin is produced in the pineal gland. It plays an important part in the regulation of circadian rhythms and influences the sleep-wake biorhythm. Throughout the day, melatonin concentration in the blood is very low, mostly even below the detection limits. The highest blood levels are seen between 1 and 3 in the night. |
