Good.
Verified Purchase
This product is recommended in cases of sleep and circadian rhythm disorders, anxiety and restlessness. Melatonin is the main hormone of the pineal gland, a regulator of the human circadian rhythm. It is produced by the body in the dark and has been called the "sleep hormone". I take it according to the instructions.

Okay.

Yes, melatonin is a sedative, but at the same time, the body must produce it in sufficient quantities, receiving it only in special cases, which must be determined by a specialist.

Melatonin is a natural hormone produced by the pineal gland (epiphysis) and regulates the human body's internal biological clock. Its main task is to signal the body that it is time to rest, preparing the body for sleep and recovery.

With this melatonin I sleep soundly and sweetly. I suffer from insomnia, and melatonin is a lifesaver.

This is not the first time I've taken this melatonin, I take it periodically as needed before going to bed. The 5 mg dosage works great - I fall asleep literally 20-30 minutes after taking it, even if the day was stressful or my regimen was disrupted. Sleep becomes deep, without constant night awakenings, and in the morning there is no feeling of "brokenness". Also, a huge jar of 240 tablets will last a very long time!

The previous dosage of 10 mg was too heavy, so I'm switching to 5 mg!
