It really works
My husband got this for us a few months ago and I can definitely tell a difference in product then other ones, it makes you feel more relaxed and I truly feel like I sleep better at night. I feel like I can get up easier in the mornings and I don't feel tired. I take 1 around 8pm and I feel comfortable by 8:30 and then go to sleep. I have recommended this to my mom that takes prescription sleeping pills and she says she like it too.

Trabajo con Eventos y es agotador, no estaba durmiendo bien en las noches y tenías calambres en mi mano derecha. Consulté los beneficios del Magnesio para estos fines, compré esta marca por recomendación de una amiga, tengo poco consumiendolo pero he visto algunos cambios, me duermo mas relajada, no tengo calambres en mis manos. Hasta el momento me gusta lo que veo y siento.

Brain overstimulation and insomnia..
So my son (23) has had insomnia since he was about 6. We’ve tried everything from modern medicine to VARIOUS natural medicines to no avail UNTIL he came across a video on YouTube of a guy w his same sleeping problems. Bought this, along w 4 other supplements and now he’s about 90% better thank God!!! Besides magnesium he takes: Life Extension Glycine 1000 mg Natures Trove L-Theanine 200mg Evolution Nutrition Apigenin 50 mg He also took sweet tart cherry juice but the first time he ran out of it he realized he didn’t need it as long as he took the above. It’s been several months he’s been taking these supplements so it’s not like he’s only taken them a few days. It’s been around 6 months. A couple weeks ago he noticed they weren’t as potent but then realized he needs to exercise at least 2-3 times a week to feel better. Take the dosage recommended on the bottle. Btw, the L-Theanine is the best for brain overstimulation. Hope this cocktail works for you!!

An Effective, Clean Magnesium formula
I recommend this excellent Magnesium formula from NutriVein. It contains 3 of the most outstanding forms for brain and nervous system health in a perfect ratio, and I was thrilled to find a formula containing these particular 3, as it's unusual and difficult to find. I also appreciate that it contains NO fillers, love the quality, and find the price to be reasonable.

Sentí una diferencia notable aunque nada escandaloso, una leve mejoría. Dejé de tomarla porque me daba calambre en la mano y el pie y un poco de adormecimiento en esas áreas y únicamente tomaba esas pastillas una sola al día a modo de prueba. Las hubiese seguido tomando sino fuese por el calambre.

I started having lots of trouble with my sleep. My body moved suddenly while I was sleeping and it would wake me up with my heart racing. Sometimes it was my arm others my leg that would just move really abruptly during my sleep and waked me up with racing heart and a weird feeling. I had also lots of dreams and I didn't connect these events at first with this supplement, so I went to a neuropsychologist and a cardiologist, I had lots of tests done before I connected the dots and stopped taking it. It was an expensive supplement, with good reviews and recommendations so I didn't think it was the reason for all these issues. Maybe I'm part of that 1%, so I'm speaking only for myself. Just pay attention when you take it or any other supplements, as sometimes it doesn't go like you expect. In the end, my health insurance is good so I didn't pay for all the appointments and check-up I went through. In a way it was even good because it got me to check out some aspects of my health that I didn't think of, but it took time and resources to find out that my health was perfect. And that stopping the supplement was the only option left. Maybe 1 star might seem not fair, but I'll keep it just to make people aware of this (maybe) 1% that my experience might represent.
