I have recently began to use this product, in conjunction with Castor oil packs. What happened, was that I started feeling as if my magnesium levels feel affected. Although the manufacturers assure you that any nutrient absorption is minimal, I feel that it may not be minimal with me. I have had to resume using Magnesium gel, and upping my intake of Magnesium Taurate, as well. I did notice a reduction of acid reflux, and have actually forgotten to take my GERD medication a few days with no ill effect. My question is whether anyone else has used this product long term, and if you have found it to be beneficial over all? Also, if you felt that it wasn't beneficial, what went wrong for you?
