What got worse for some people
In their own words
“Fixing my magnesium deficiency was life-changing. No more headaches, brain fog, sleep issues, back pain, or blood flow issues.”
“I'm feeling pretty suspicious that it's the magnesium... I'm thinking the magnesium is only hurting me more than helping now.”
“I'm taking 400mg Solgar Chelated Magnesium in the morning. It makes me feel calm and lucid, but utterly unmotivated to do anything. I've lost all sense of urgency.”
“Supplementation of magnesium and quitting PPI's has greatly improved my quality of life.”
“I found that it was too sedating for me, and it would make it difficult for me to focus. But after about 4 weeks with no magnesium, I will start to become irritable and anxious.”
