Positive experiences
“The next day, my legs felt amazing. I could walk again without feeling like my legs were deadweight.”
“I had heart palpitations for 20 years and just recently started taking magnesium oxide about 4 months ago. Life changing.”
Negative and mixed experiences
“I've tried various forms of magnesium over the past year including threonate, glycinate, citrate, oxide, and taurate. They all give the same negative side effects.”
“I was taking crappy magnesium oxide supplements for years with basically no effect, besides diarrhea if I took too much magnesium oxide. Magnesium oxide has basically no bioavailability.”
“If it's oxide, which has 4-5% bioavailability, will probably do nothing for you like it does for me.”
“Oxide has shit bioavailability but that didn't bother unless I too ka fairly large dose, it's basically a diuretic.”
“I feel emotionally blunted when I take magnesium during the day, but it's great at night.”
“I'm taking 250mg of magnesium oxide twice daily to see if it could help with my depression/anxiety/fatigue combo. Well, it has.”
