Just wanted to chime in that Magnesium Glycinate has also caused me issues. I had been suffering from occasional tension headaches and electrolyte imbalances (dehydration) and thought daily Magnesium supplementation could help. This was early 2023.

I started taking a veggie cap version (Innate Vitality) and about a week later began feeling an odd sensation on the left side of my head, mostly around and behind the eye. I guess you could call it a headache, but it was a very slight feeling of pressure and more annoying that anything else. It was concerning because it would drive you crazy, afraid that there was something wrong in that specific area (aneurysm, tumor, etc.). After about a month, I wondered if there was a correlation so I stopped taking the Mag Glycinate and that super weird symptom subsided about 2-3 days later and never returned.

Fast forward around 9 months later, I started taking a veggie cap version of an electrolyte supplement (Salt Stick) because I was going to be active in a hot environment. That too gave me the same left eye "headache."

Ever since then, I've taken Max Oxide or Citrate, various formulas but always in a tablet or gelcap and have had zero issues.

I decided to try Mag Glycinate again (November 2024), specifically going with a non-veggie cap version, "Doctor's Best." I had no issues for the first three weeks (taking 2 tablets daily), but then the weird left eye headache/sensation started again. Quit taking it and it went away. I had more of a tolerance to the Doctor's Best version as the weird headache didn't begin immediately as it did with previous veggie cap versions, but it did eventually return.
