I have a reaction to magnesium citrate also. When it has been taken, there doesn't appear to be a need for my l-dopa supplementation(fava tincture). I have not yet found anything currently that is helping with constipation. Have needed to take the liquid magnesium citrate in bottle to get anything moving. This reaction of not needing extra l-dopa puzzles me, and it has happened twice now, even as I type. Have not taken tincture for a whole day and nite and still am able to type quickly with less mistakes than usual and play faster than usual on mandolin. Needs research!!!!
