iHerb Customer Reviews

Helps keep my nerves from twitching.

I use this form of magnesium so I won't get loose stools. Balancing the magnesium with the calcium makes my nervous twitches go away.

This was a good mag tablets the only thing tablets are bit larger then I would like them to be, not happy to take them I prefer another brand that comes in smaller tablets. Check my profile for more info on what I have found to be helpful.

Bad Reaction

Posted by HealthandBeautyGirl on Jun 05, 2017 | Verified Purchase

I purchased this product for the relaxing benefits of magnesium and B6. I have previously taken magnesium with no issues as well as B6 and B complexes with no issues. However, this combo in Source Naturals Ultra-Mag made me have the most restless sleep ever! Every night! I would toss and turn and wake up with each turn doing this odd, involuntary stretch with my arms! It was the weirdest thing ever. I hoped it would resolve itself with continued use but it wouldn't stop. Once I discontinued use of this product all the symptoms went away! So much for saving money and how many supplements I take by combining these 2 in one. I had to give this bottle away and I am trying a new magnesium supplement. I do take magnesium oil as well which I love but it's not enough for me. Check out my page for more reviews and info!
