It works. I have been using it for a month and I can say it's a quality product. I sleep better and wake up refreshed. The ingredients are safe and beneficial to over all body health. The size off the pills are okay to swallow and odorless. The dosage is good. I'll recommend it to any one who want to improve the quality of their sleep as good sleep medication.

Good quality sleep support with convenient dosage
Verified purchase
Very satisfied with the quality of this sleep supplement. The ingredient combination works well for relaxing before bedtime without feeling heavy the next morning. The dosage is easy to adjust depending on your needs, and the tablet size is small enough to swallow comfortably. After regular use, I noticed clear benefits, falling asleep faster and waking up feeling more rested. No unpleasant taste, which makes it easy to take daily. The product feels reliable and effective for improving sleep routine. Overall, a solid supplement with good quality ingredients and noticeable sleep benefits.

A Lifesaver for Tough Nights
Verified purchase
NightRest is my go-to when I have one of those really difficult nights where nothing else works. It has a deeper, stronger calming effect compared to regular sleep supplements, and you can actually feel your body settling down after about 30–40 minutes. I love that it doesn’t feel like a “drug knockout” — it’s more like your system finally gets permission to relax. On nights when magnesium and NOW Sleep aren’t enough, NightRest gets the job done. And despite being stronger, I still wake up without that heavy or foggy feeling. For anyone who deals with occasional hard nights, this is a powerful and reliable option. Highly recommended!

great for sleeping
Verified purchase
This supplement has wonderful benefits and ingredients, such as aminoacids. The tablets have 1 inch (size), so if you have problems in swalling, better not to buy it or you could break it into 2/3 parts. The dosage is 1-2 tablets 30-60 min before going to bed. The quality of source naturals products are remarkable and very reliable.

Deep, Restful Sleep and Fresh Mornings 😴✨
Verified purchase
Source Naturals Sleep Science® NightRest™ with Melatonin is one of the most effective natural sleep formulas I’ve ever used. It combines melatonin with calming herbs and amino acids like GABA and valerian root, creating a gentle but powerful synergy that helps me relax before bed and fall asleep naturally. What I really appreciate is that it doesn’t knock me out — it eases me into sleep smoothly, and I wake up feeling refreshed, not groggy. The tablets are small and easy to swallow, and because the bottle contains 200 tablets, it’s a great long-term value. I also like that the formula feels balanced — not too strong, but strong enough to make a real difference in sleep quality. ⭐️⭐️⭐️⭐️⭐️ Highly recommended for anyone struggling with restless nights or inconsistent sleep. This product delivers calm, deep rest, and clear mornings!

It works!
Verified purchase
I was trying out many tablets to help me fall asleep better and to wake up refreshed in the morning. These are really great. The ingredients are superb and the size of the package is great. They are not hard to take nor do they have an unpleasent taste. I felt the benefits after taking these tablets for approx a week.

ONLY NEED HALF HAHAHA
Verified purchase
Tried 2 caps to start and let’s just say it works good 😃 the quality is definitely there with the ingredients, beware though melatonin has its drawbacks when having too frequently I use only 1 capsule with some magnesium glycine and it’s wonderful 🙂 I have insomnia from weed withdrawals and this beats it 😎
