This is a neurohormone produced by the pineal gland of the brain that regulates circadian rhythms ("biological clock"), controlling sleep-wake cycles: its production increases in the dark, promoting sleep, and decreases in the light, helping to wake up. It also has antioxidant properties, strengthens the immune system and has a positive effect on the cardiovascular system, and as a supplement helps with insomnia. I love this melatonin for its moderate dosage and mild effect. I recommend it!

The quality is high. The ingredients are listed on the packaging. The tablets are small. The dosage is excellent, ideal for those who have trouble falling asleep. I think everyone knows the benefits of sleep, and this is a tool for improving sleep in the optimal dosage. The taste is neutral.

Mild dose to help you fall asleep
Verified Purchase
Melatonin isn't always better at high doses. Sleep is okay, but if you want to enhance your sleep, try a lower dose, like this one. Some websites list milligrams in specific doses, but I'm not sure if that's misleading or misleading. I've found this product to be very effective for me, with so many benefits! I take one pill half an hour before bed after my daily workout. It's very convenient, doesn't make me feel dizzy, and doesn't strain my body. My recovery the next day is noticeably better.

Good for children

Good for children... for those who have difficulty sleeping... a good dose for children... the great thing is that teenagers can be given two tablets to make the dose exactly a standard dose of 2 mg... to be used as needed

“Effective and gentle melatonin for sleep”
Verified Purchase
I've started using this melatonin and it has greatly improved my sleep quality. It gently relaxes me without leaving me feeling groggy when I wake up, and I'm able to fall asleep faster and sleep more deeply. The dosage is appropriate and easy to take. I especially recommend it for people who have difficulty falling asleep or who wake up several times during the night.

It's very helpful for sleep. I usually take 1mg, sometimes 2mg. I'm less sleepy after waking up. I'll buy it again.

Melatonin is a hormone secreted from the pineal gland in the brain, also known as the "sleep hormone," that regulates the sleep-wake rhythm (body clock). Its secretion increases when it gets dark, inducing sleepiness, and its secretion is suppressed when exposed to light at night. In addition to supporting sleep, melatonin has been studied for its various health benefits, including its strong antioxidant properties.

I've been taking these vitamins for several weeks now, and I'm really feeling the benefits. I feel more alert, have more energy and mental clarity, and my mood has improved. My constant fatigue has disappeared, I sleep better, and my skin and hair look much healthier. I especially like the balanced composition: it contains B vitamins, vitamin D3, C, E, zinc, magnesium, iron, selenium, and biotin—everything you need to support your body, immune system, and nervous system. The capsules are easy to swallow, gentle on the stomach, and well-absorbed. I'm very pleased with the quality and results! This is an excellent complex for those who want to maintain their health, energy, and beauty every day.
