This is Good Stuff!
This Magnesium L-Threonate Complex is new to me. I really like it because it has completely lifted my brain fog! I faithfully take it everyday. The recommended dose is three small capsules. There are absolutely no fillers, no hidden or artificial ingredients, or artificial colors. This is the first time I have ordered the “Why Not Natural” brand, and am impressed with its quality.

Awesome Sleep Aid!!!
This product is a real godsend for me and my wife! We are sleeping much better, more deeply, and falling asleep much more quickly, so we feel this product is directly responsible for greatly improving the quality of our sleep. No latent drowsiness whae we wake, no after affects. An excellent product fo more "mature" folks! Very highly recommended!!

Great sleep aid thus far
I started taking ..Why Not Natural magtein magnesium L- threonate , L- theanine & apigenin about two ago.. I struggle nightly with lack of sleep and waking numerous times during the night..to the point where I barely get 2-3 hrs of any kind of restful sleep.. I have been taking other supplements and non prescription sleep aids and most make very drowsy the next day and at times morning headaches.. This supplement thus far has helped me sleep so much better..no waking numerous times and staying awake in the middle of the night ..I wake refreshed in the morning… At this point I will continue using Why Not Natural sleep supplement..I hope this will continue to help with my sleep…

Helps with sleep
I’ve tried every magnesium & this one seems to give me the best results for sleeping. On nights I forget I feel like it takes longer to fall asleep. I’ll definitely repurchase. Easy to swallow as well, no adverse reactions.
