Customer photo review of Magnesium L-Threonate 1000mg Magtein® Capsules

AMAZING! You’ll wake up feeling rested. This product is great, you won’t get the feeling of drowsiness or being drugged. Just naturally will fall asleep, if you wake up in the middle of the night you will fall asleep with ease, and when is time to get up you feel rested!! I’m so pleased with this product. I highly recommend it. Also, an interesting note, I normally don’t remember my dreams. Now I dream vividly and remember the dreams! ?????

Are you struggling to relax enough to fall asleep? You're not alone; my mind used to race non-stop, constantly trying to solve problems. Even if I woke up in the middle of the night, falling back asleep felt impossible. After some thorough research, I discovered a specific combination of magnesium that came highly recommended. Let me tell you, it worked wonders from the very first night and has continued to do so every night since! I can’t stress enough how effective it has been. I've already shared this game-changing solution with my colleagues and family, and I wholeheartedly recommend it to you too. Don't miss out on this opportunity for a peaceful night's sleep!

I reordered this after I figured out how to use it. Depending on my sleepiness, I take one or two pills 15 mins to half hour before bed. I always wake up around 3 for bathroom and then I couldn’t go back to sleep. But I discovered if I take one or two more pill at that time, I go back to sleep! You can’t do that with melatonin. With melatonin I need 8 hours and I’m groggy. With this product, I wake up refreshed. Hope it helps!

I was using a different magnesium to help with my sleep but it didn't work. I switched to this brand and wow, I actually sleep now! I have this on subscription and won't stop taking it.

Customer photo review of Magnesium L-Threonate 1000mg Magtein® Capsules

I’ve struggled with sleep ever since I started trying to wean off escitalopram, which I had been relying on as a sleep aid. My sleep quality had completely tanked—bad scores, no ability to sleep in, terrible latency, and just a general inability to get the deep, restful sleep I needed to function the next day. Honestly, I wasn’t sure I’d be able to get off Xanax because the poor sleep was affecting my daily life so much. That all changed the moment I started taking these magnesium supplements a week ago. From day one, my sleep scores jumped to over 85, which was unheard of for me. I’m now consistently sleeping 7+ hours a night, feeling refreshed when I wake up, and falling asleep within 20 minutes—something I hadn’t experienced in a long time (even on Xanax sometimes). This supplement has been a complete game-changer for me. It’s been a huge aid in my journey to get off Xanax, helping me get the quality sleep I need naturally. If you’re struggling with similar sleep issues, especially during a transitional period like this, I cannot recommend this product enough. It’s already made a massive difference in my life.

Works as advertised, though for the first time in my career I was late to work because I overslept, not once but 3 times in a week. Dreams are much more vivid and my rem sleep has improved significantly.

Magnesium L-Threonate 1000mg Magtein® Capsules

I tried this 2 months ago, slept great, but forgot to order again when I ran out (ADHD+Single Parent = memory loss). Last month, my sleep was so horrible, and for some reason I didn't connect that I had stopped taking it. Ordered again, took it for the first time last night. 7 + hours of sleep, uninterrupted. 10000/10

A very excellent product with a clear price-performance ratio. Magnesium threonate is the only source of magnesium that directly supplies the brain, and you can expect to improve cognitive abilities and additional sleep benefits by taking it.

This is a great product! I had my doubts, but I actually found I sleep better at night if I take them in the evening. I also noticed my cognitive function is better the next day, which is usually the result of better sleep.

Customer photo review of Magnesium L-Threonate 1000mg Magtein® Capsules

I’ve been meaning to try magnesium as a sleep supplement for quite some time, especially after becoming more physically active as I have read it also has benefits for muscle recovery. I frequently use melatonin to aid in falling asleep but end up building a tolerance and having to take breaks from it. Magnesium L-threonate has been touted as one of the best natural sleep and muscle supplements out there. So far I can say this stuff works like magic. Every night I have taken it I’ve had some of the deepest sleep I have in years. I try not to take it every night in order to avoid building up a tolerance, but I’ve noticed even on the nights I don’t take it I wake up less during the night and feel more rested in the mornings. I wouldn’t recommend taking this until right before bed, since whenever I take it I begin feeling drowsy and relaxed in under 30 minutes which is perfect for my use case. I am unsure if the Apigenin gives this supplement a leg up to other magnesium supplements without it, but since this has worked wonders for me so far I plan to stick with this formulation!

Unlike regular magnesium, Reviame reaches the part that's stuck in the fog

Around 1 in 3 adults don't meet their recommended magnesium intake. And even for those who do, general dietary magnesium isn't built to reach the brain the way it's needed most — that's where Magnesium L-Threonate comes in.

FAQS

What ingredients are used and how do they work? +

Reviame capsules contain Magtein® (magnesium L-threonate). Magtein® is a highly absorbable magnesium that crosses the blood–brain barrier to support memory, focus, and sleep quality.

I've already tried magnesium and it didn't do anything. Why would this be different? +

Because what you tried was almost certainly a magnesium that never made it past your bloodstream.
Most forms — even the well-absorbed ones — stop there. They calm your body, but they don't cross into your brain.
Magnesium L-Threonate is different: it's specifically studied for its ability to reach brain tissue, not just your blood.

How long before I actually notice something? +

Most people notice small shifts in the first week or two — a word coming to you faster, one less "wait, what was I doing" moment.
The deeper changes — the fog actually lifting, feeling sharp again instead of scattered — usually show up between week 3 and week 4, once your body's built up consistent levels.
Give it 90 days. If nothing's changed, we'll refund you.

Is 2000mg too much? I'm sensitive to supplements. +

2000mg per 2-capsule serving is within the standard daily range for magnesium L-Threonate. If you're new to magnesium or very sensitive, start with 1 capsule for the first few nights and see how you feel.

Can I take this with other supplements or medications? +

Magnesium pairs well with most supplements, including vitamin D3, K2, and B-complex. If you're on prescription medication — especially blood pressure meds, diuretics, or antibiotics — check with your doctor about timing. Magnesium can interfere with absorption of some drugs if taken at the same time.

What if I miss a night? +

Nothing bad happens. Magnesium builds up in your body over time. Missing one or two nights won't undo your progress. Just start again the next night.

What if it doesn't work for me? +

We’ll give you your money back! (Yes, even if you’ve been using it for weeks.) 

All Reviame products come with a 100% satisfaction money-back guarantee for 90 days – if it doesn’t work for you, send it back & we’ll refund you in full.
