Review: Really does work! - This magnesium complex has been enormously helpful for me. I consistently fall asleep in 5 minutes now, whereas I used to be restless for 20 minutes before I could fall asleep. Also, one time I accidentally took my PM supplements in the AM, and I was so calm and focused all day at work because of the magnesium. One last thing I’ll mention is that I have a very sensitive stomach but I’ve never had an issue with this supplement.
Review: IT WORKS - Absolutely GODSEND!!! This truly works and I have tried them alllll. The times that I do not take it I can feel the difference. This product has given me my quality of life back. It helps with vertigo, aura migraines and with sleep. I can also feel the brain fog disappear. I have tried to get cheaper and different supplements but I come back to this exact brand. I hope that they never ever change the quality.
