Our Members Asked:
Is it true that magnesium bisglycinate from BioSchwartz is less likely to cause a laxative effect than other forms of magnesium?
Reviewed and edited by Tod Cooperman, M.D.
Answer:
[Update: (1/26/20) A recall announcement may affect this product.]Certain forms of magnesium, such as magnesium bisglycinate and some others, may be less likely to cause diarrhea, as explained in the Choosing the right form of magnesium section of the Magnesium Supplements Review. However, it appears that BioSchwartz magnesium bisglycinate is not properly labeled and may provide a much lower amount of magnesium that expected. See the full answer >>

December 3, 2020"ConsumerLab.com has come across other magnesium supplements that are not properly labeled ..."
Isn't mislabeling supplements illegal? Where can mislabeled products be reported to the FDA: do they have a form for this?

July 1, 2018My family has been taking magnesium supplements for many years including Mag Glycinate, Taurate and Theonarate but all caused a laxative effect for my wife. I switched her to liquid magnesium chloride and no more problems for her. That form of magnesium is covered in the Consumer's Lab review and the brand mentioned is what she uses. She also suffers from Parkinson's which will result in restless leg syndrome after going to bed unless she takes the mag chloride beforehand.
