Deep and restful sleep without insomnia 😴🌙
Verified Purchase
Melatonin is an excellent aid in falling asleep quickly and improving sleep quality without feeling heavy upon waking. The dosage is strong and effective, and the pills are easy to swallow. I recommend it for anyone who has difficulty sleeping or has irregular sleep schedules.

Good value for money!
Verified Purchase
I take this every day along with my sleeping pills. Since it's a supplement, not a drug, I'd love to be able to stop taking the medication and sleep on this alone someday! It's tasteless and small, so it's easy to take!

A potential alternative to high-dose melatonin
Verified Purchase
My father, who is in his 70s, was taking 10mg. He said he was waking up in the middle of the night, but was sleeping for a little longer and seemed to be doing well. Swanson's 10mg melatonin is the most cost-effective, so I have now switched to it.

It's cheap and effective
Verified Purchase
I usually get sleepy in about 30 minutes. I drink it after putting my kids to bed, when I'm enjoying some alone time and feel like I need to go to sleep in about 30 minutes. Even if I drink something with caffeine, like brown rice tea, I get sleepy with just 5mg. I use it almost every night, along with other melatonin supplements, and I haven't had any problems with the effectiveness. What's great about this product is that it's tasteless, not particularly large (but not small either), easy to drink, and inexpensive. It's not particularly different from other melatonin supplements.

Great
Verified Purchase
Melatonin is a powerful free radical scavenger naturally produced by the pineal gland and found in large quantities in the gastrointestinal tract. It plays a role in many biological functions of the body, brain, and glands, including regulating sleep-wake cycles, regulating the immune system, and maintaining the health of the gastrointestinal tract.

In the same 10mg of melatonin
Verified Purchase
Have you ever felt that even with the same amount of melatonin, the effects of different brands (products) are different? In other words, even with the same 10mg of melatonin, company A makes you sleep soundly, company B wakes you up in the middle of the night, company C wakes you up easily, and company D wakes you up the worst. Is this the kind of difference I often feel, but am I the only one? So, there are a lot of positive aspects to this product. I can definitely feel this. Because when I switched from 10mg of melatonin to this, I clearly felt, "Hey, maybe this is good!"

Good quality
Verified Purchase
Melatonin is being exported to Thailand, but there are only a few brands left. This brand is still usable, and the quality is okay.

I can't do without it because drinking it before bed helps me fall asleep more easily.
