This magnesium
I stopped taking this because I thought I was getting too much magnesium, well let me say this that 3 months was ruff. My mood changed from good to bad, and started to feel sluggish,
And a lot more. The only thing I changed was I stopped taking the magnesium,
So I got the same kind I was taking before, it took a bit to change all the negative, back to Positive !!! I was feeling like my self again. Believe me I've learned my lesson,

Vague, but not DECEPTIVE
I rarely spend time reviewing products but I felt the need to correct the review claiming the VItamin Shoppe's Magnesium Threonate is deceptive.

The amount of elemental magnesium in 2000mg of Magtein is 144mg magnesium. Most labels for Threonate say "Magensium (from 2000mg Magtein Magnesium L-Threonate). The label for Vitamin Shoppe Mag Threonate states "Magnesium - (Magtein Magnesium L-Threonate)" which led the reviewer from NY to think it was not sourced soley from Magtein. No other

DECEPTIVE....NOT from 2000mg Magtein!!
Returning this to store! All other brands mention that it is SOURCED from 2000mg of Magtein and this does not mention it at all! When calling customer service about it, she told me it is ONLY 144mg of Magtein! If it's not sourced from that original 2000mg of Magtein, what's the point and why not mention it as others do?? Unlike Dr. Mercola's and all the other brands, no wonder I am getting leg cramps while using this product as there's not enough Magnesium in it!
