Sleep quality has improved.
Verified Purchase
After taking it for a while, I've noticed a significant improvement in my sleep quality. I seem to sleep more soundly than before, even in the middle of the night when there's thunder. I wake up feeling refreshed. The ingredients are probably good, considering so many people use it. The granules are small, have no strange taste, and are easy to swallow.

### My User Review: iHerb's Melatonin Products. As someone whose sleep is often disrupted by work stress and jet lag, I decided to try a melatonin product recommended on iHerb. This time, I chose Natrol 5mg Fast-Dissolving Tablets because they not only offer a moderate dosage but also come with a natural strawberry flavor, making them easy to swallow. On my first try, I took them 30 minutes before bed. The tablets dissolve quickly, taste delicious, and don't require water, making them very convenient to use. About 15-20 minutes after taking them, I felt my body gradually relax, my mind stopped wandering like normal, and I fell asleep much faster than usual. What surprised me most was that my sleep interruptions were significantly reduced, and I even slept through the night, waking up feeling more rested. After taking them for a few days, I noticed a significant improvement in my sleep problems caused by work stress, and my overall mood became more stable. I was very pleased with the packaging. The compact, airtight bottle makes it easy to carry, making it perfect for travel. iHerb also delivered very quickly, and the product arrived in perfect condition. I think the price is very good, especially during sales. Overall, I'm very satisfied with my experience with melatonin; it's effective and easy to use. I'll definitely repurchase and recommend it to friends who have trouble sleeping!

I use it constantly and am very pleased with the quality. The results are immediate and last for a long time. The ingredients are perfectly selected, the tablets are the perfect size, and the packaging is high-quality. I highly recommend everyone try it; you'll only buy it afterward. It's very effective, calms the nervous system, tastes great, and gives a lot of energy. It's good for health, age, and hair.

This product is slow-release, thus helping to release melatonin gradually for more than six hours.
