Review: This suppliment works - This form of Magnesium is perfect for someone looking to improve their mood. Magtein is a clinically proven form of magnesium to reach your brain and nourish your cells. Nootropics Depot is one of the few suppliment brands that I trust not to cut corners and deliver uncompromising quality. The capsule is small and easy to swallow. If you're possibly deficient in magnesium, start slow as the effects will be more dramatic when you start taking a quality suppliment. I highly recommend.
Review: This is better than any TV subscription out there folks.... these dreams are WILD! - I've been dreaming every night since I started taking these! Before then, I would remember maybe a handful of my dreams every year. I wake up remembering details from the dream that had lots of plots and turns, so I was well-entertained in my slumber. They also help put me to sleep quicker and I feel better-rested on MOST days, but not all. I say that because if I don't get enough sleep while taking Magtein, then I'll feel it a LOT worse the following day. But so far, so great and I'm happy I got them!
