The best Magtein I have tried thus far
I take double the dose because when I double the dose it improves my ability to pay attention and I am less distracted. Yes I have ADD but no longer take Adderall for it. Being 56 years old Magtein really improves my memory and restored it to like new by ten days of use. Shockingly It woke me up from a light sleep late evening as memories rushed in and I have been taking it ever since. I have been taking it 7 months now and over time it has slowly but surely improved my short term memory so that it also is nearly the same as before. I have seen slight improvements in working memory enough to be encouraged It may become an advancement from a historical standpoint. This is my second bottle by Teraputics. I was taking 2 bottles of NOW brand per month for my memory and concentration because it is the cheapest but when Amazon ran out Teraputics is the product I decided to try next. But I like this brand better as it seems more concentrated or I should probably say more bio-available so I decided to by it and pay the extra money over NOW brand. I just wish it were cheaper. I am hoping to ask them for a deal if I buy 20 bottles in advanced as it is a must have for me. With this second purchase they included a free bottle coupon and not a buy one get one free. Right now I am very happy to get the free bottle.

Daily Intake on Label Confusing
Label was not clear regarding milligrams per pill. Title label stated 2000mgs per serving (of 4 pills), but “supplement label” states 4 pills is 144 mgs per serving as a 34% of daily value.
Very confusing. Not sure which metric to go by for daily intake.
