The sleep supplement that made jet lag a non-issue
I’m currently midway through a surf trip to the Maldives and Bali. Between jet lag and long days, my sleep is usually horrible on trips. I brought Synchro Rest with me on a friend’s recommendation, and after 3 weeks on the road, I’m convinced this stuff is gold. I’ve tried a bunch of sleep supplements before, but most either don’t work, knock me out too hard, or leave me foggy the next day. Rest is different. Its been helping me wind down and get some solid deep sleep. I looked into the ingredients and they’re all backed by legit science. You can tell it was formulated by someone who actually knows what they’re doing. It’s been a total lifesaver on this trip. Highly recommend if you want better sleep, especially while traveling in different time zones or recovering from long, active days.

This one is the best — tried so many and found my fave
I have tried many other magnesium sleep supplements but this is the best at getting me to sleep and staying asleep. First, it kicks in fast! Second, the formulation with other supplements make this more effective than other magnesium products. I’m hooked!

Not 28 Servings
Does it work? Definitely the first couple of times I can notice it’s easier to fall asleep and I don’t wake up as groggy as I would with melatonin however it is not nearly as strong as melatonin. My big complaint is that there is definitely not 28 1 tablespoon servings more like 15-19 max I think that’s where the real problem in this product lies.

10/10
This has really improved my sleep quality. I fall asleep faster and stay asleep through the night. I appreciate that it doesn’t have melatonin or any sedatives — just clean, functional ingredients. Great as a bedtime drink with honey and lemon!

For Me, It Works
I’ve had trouble falling asleep my entire life, generally taking hours to do so. I’ve made it a mission to try different supplements to help with this the past couple of years, and while I don’t like the flavor of this product (kind of like lemonade combined with green tea), it’s the most effective one in the bunch. I fall asleep faster and stay asleep, which is all greatly appreciated. Your mileage may vary, but this has been my experience.

After night falls (and you haven't)
I've been taking magnesium before bed for years now. I usually find the cheapest magnesium supplement, often magnesium carbonate, and take it in the evening a bit before bedtime. It seems to help me relax, perhaps in a subtle way. If anything, I feel a bit calmer, perhaps less muscularly tense, but I wouldn't say it obviously helps my sleep. Enter Synchro Rest. I thought I would give it a try after a friend recommended it, and I was curious if I would find a difference from the other magnesium I take, as it is in different chemical/mineral forms, and has a few other additional sleep-aid ingredients as well. The synchro rest dissolves easily in water, and has a pleasant lemon/herb flavor. It doesn't leave a heap of gritty sand at the bottom of my cup as my usual mag supplement does, and in general is a much more pleasant drink. I would say the real benefit is that it actually seems to improve the quality of my sleep, mainly in that my slumber seems deeper, less interrupted, and weirdly so far I have had much less disturbing dreams and restlessness. I'm not sure exactly how or why this translates as I wasn't expecting my dreams to be affected and, I have only been taking rest for two weeks now, and so I haven't finished my testing. . . So far I would rate it far superior to the other magnesium I take, especially if compared as a sleep aid and not just a nutritional supplement and well worth the slight uptick in price. Sleep is, after all, priceless. . .

Great for deep sleep
I spend a lot of late nights on my computer, and afterwards my brain is overactive. I was researching magnesium and decided to try Synchro Rest. I seem to fall asleep faster and stay asleep through the night. What I like most is how calm my mind feels without feeling sedated. I wake up clear-headed and not groggy. It’s become a part of my night routine, and I can tell I’m getting deeper, better-quality sleep. Highly recommend if you have trouble winding down after long work sessions or too much screen time.
