Customers say

Customers find this magnesium supplement to be of good quality and value for money, with positive effects on sleep, helping them sleep like a baby and providing a profound sense of relaxation before bedtime. Moreover, they appreciate its health benefits, particularly for brain health. However, the magnesium content receives mixed feedback, with some noting it's better absorbed while others say it's the least bioavailable form for the body. Additionally, effectiveness and absorption show mixed results, with some reporting it works within 30-45 minutes and is easy on the stomach, while others find it ineffective and difficult to absorb.

    This does WONDERS for me! It’s the most cost effective one I could find on the market, and it WORKS. I take it before bed, wait thirty minutes, then I’m SOUND asleep. I also stay asleep for a good long while. I very much struggle with fast heart rate and anxiety, and this has calmed my middle of the night panic attacks. I had some very odd dreams when I first started taking this, but nothing that made me want to stop taking it! I take 2 per night.

    I cannot say enough good things about this product! I believe this will be my sixth time ordering it!

    As a woman in my 40s navigating the rollercoaster of perimenopause, this supplement has been nothing short of incredible. One of my biggest challenges was waking up at 3 or 4 a.m. and struggling to fall back asleep—but not anymore. Since I started taking this at night, I sleep soundly through the night and wake up feeling rested and refreshed. It’s been a total game-changer. I’ll keep buying this again and again!
