good product, good price

While not a hardcore insomniac, I've struggles with sleep issues for decades. I had mixed results with melatonin tablets but, for some reason, sublingual melatonin works like a charm! A spray or two under the tongue before bed brings the sandman within 5 min utes or so. Safe, effective and economical. Thank goodness for Iherb! I believe that nutritional supplements saved my life. I've tried a lot of products, and I know what works and what doesn't. My reviews are honest, straighforward, and based on my experience. Read my other reviews to quickly learn from my three decades of research and experimentation.

melatonin spray

This spray helps get my husband to sleep. He prefers liquids over solids when taking supplements so this is a perfect option. it has a decent taste and you spray it on the tongue or the back of the throat. It's a low dose of melatonin, so you can play with the dosage, taking an extra spray here and there as needed.

Source naturals sleep science melatonin

I’ve been using Source Naturals Sleep Science Melatonin for a few weeks, and it really helps me fall asleep faster and stay asleep throughout the night. I wake up feeling more rested and refreshed. The tablets are easy to take and gentle on the stomach. Highly recommend for anyone struggling with occasional sleeplessness or jet lag

Чудово!

This Melatonin NutraSpray is a total lifesaver for my insomnia. Since it’s a liquid spray, it absorbs much faster than tablets or gummies. I usually take it about 15-20 minutes before bed and I’m out like a light. The orange flavor is surprisingly pleasant and doesn't leave a weird aftertaste. I love that I can control the dosage easily with just one or two sprays. Definitely my go-to for a good night's rest!

I decided to try melatonin spray. I can say that quality is good, but you must find melatonin brand that works for you.

Nice Flavor

This melatonin spray is easy to use, and the orange flavor is pleasant without being too strong. I like that it absorbs quickly, and it helps me wind down in the evening. It’s gentle, so the effect feels natural, not overwhelming. Overall, a convenient option if you’re looking for a simple melatonin supplement.

For falling asleep quickly

Source Naturals Sleep Science Melatonin is a great quality product for falling asleep quickly. Just one spray dosage is enough. Don't take it too late in the evening, or you'll still be drowsy in the morning.

melatonin

Great to have as backup for when we're out of melatonin tablets. Decent size bottle, although not as strong as the tablets due to diffence in dosage. Good quality, good sleep benefit, nice taste.

Great Quality and Works Fast

The quality of this melatonin spray is excellent — it helps me fall asleep quickly and wake up refreshed. The orange taste is light and pleasant, not artificial at all. The 2 fl oz size is convenient and lasts a long time. Great value for such an effective product. I’ve been sleeping more soundly since I started using it, and I highly recommend it.
