Not working for me 100%
Still not sure about how this magnesium affects me. I have only been taking one tablet an hour or two before bedtime. Seems like sometimes I can’t go to sleep after taking it, charges up my brain. Other times I sleep but have crazy dreams. Maybe it works for some, but not others. I’ll try to finish the bottle, but the lack of sleep after taking the Magnesium L-Threonate makes me hesitant to continue some nights. That’s mainly the reason I purchased this brand to include the reviews.

These work GREAT! This is the second time I've ordered them!
These work great! This is the 2nd time I've ordered these. They give me energy and my buddy down below get a lot of energy too! (especially in the morning!) :) I definitely recommend getting these I've tried different types on AMAZON and these are the best so far. Any other suggestions on these types of pills. Add this info in your review. May have to give it a week or so to see and feel the results and you will!
