Magnesium is one of the most important minerals in the body, but an estimated 75% of Americans are magnesium deficient. Magnesium plays a key role in over 300 enzymatic reactions, including supporting cardio vascular, bone, muscle, energy, and neurotransmitter processes. Source Naturals magnesium is attached ("chelated") to the amino acid glycine. The magnesium bis-glycinate combination enables efficient absorption, the glycinate allowing the magnesium to transfer easily across the intestinal wall. Increased absorption means more usable magnesium for your body's needs.

Suggested Use

2 tablets twice daily.

Stomach pain

Posted by Reviewer3247685 on Apr 22, 2013

I've always purchased another brand of magnesium glycinate and have never had any problems taking right before bed. I bought this brand because it was cheaper and had the "glycine" in the name and have had an upset,cramping, and sour stomach ever since. These pills are very very bitter too. I've noticed also that when I take this brand I can't take an occasional ibuprofen for my arthritis without paying the price of all day stomach cramps the next day. Switching back to my old more expensive brand! I think it did a real number on my stomach lining!

magnesium bisglycinaat

Posted by vrouwenpolibxomeer on Dec 08, 2013

goed opneembare vorm van magnesium. Veel mensen hebben een tekort aan dit mineraal, het hoort tot de basissuppletie als je minder dan 300 gram groenten per dag eet.
