Product Overview


  • Dietary Supplement
  • Hypoallergenic

A study comparing the bioavailability of magnesium citrate with magnesium oxide (a form found in many poorly-absorbed dietary supplements) found significantly greater absorption of magnesium citrate than magnesium oxide in healthy volunteers. The same researchers examined solubility and found magnesium citrate to be 55-percent soluble in water; whereas, magnesium oxide is virtually insoluble. The more water-soluble a mineral chelate is, the more absorbable it is in the body.

Magnesium and citric acid have both been found to decrease the precipitation of calcium oxalate and calcium phosphate in the urine, thus supporting good kidney health. The combination of magnesium with citrate in Thorne's Magnesium Citrate offers an attractive combination for individuals with a propensity to have calcium oxalate and phosphate particles in their urine – thought to be about 10 percent of the U.S. male population.

Magnesium is present in all cells of the body and is involved in over 300 enzymatic processes, including energy production. Magnesium is essential for maintaining normal bone density, normal cardiac rhythmicity, normal pulmonary function, and normal blood glucose regulation. Other body functions requiring magnesium include nerve conduction, methyl-group transfer, conversion of pyridoxine to pyridoxal 5'-phosphate (the active form of vitamin B6), production of energy, and muscle contraction. Magnesium supplementation appears to be a significant support to maintaining already normal bone density.

Big Tablet - easy to swallow

Posted by iHerb Customer on Oct 19, 2017 | Verified Purchase

This product appears to work - sleep improvement and less "restless leg syndrome" symptoms throughout the night. You do need to take 2 x tablets a day - so you can go through them if several family members are taken them each day. I have purchased this product twice now.

Thanks for your feedback!

Works well for me...

Thanks for your feedback!

Exceptional product for overall health and for those in need of magnesium

Posted by iHerb Customer on Oct 19, 2017 | Verified Purchase

Being a vegetarian, these capsules provide peace of mind with what one is putting into their body. The magnesium is absorbed easily making this the best product of this kind in the market.

Thanks for your feedback!

Makes me feel tired

Posted by iHerb Customer on Oct 09, 2017 | Verified Purchase

It was prescribed to me by my naturopath as I had insomnia. I take one capsule before I go to bed. I still wake up at night, and feel light anxiety, in the morning - very sleepy and have a headache, same effect has my husband. I'll try one week more if these side effects continue I have to give it away. Such a pity as other products from Thorne worked for me well.

Thanks for your feedback!

This stuff is amazing. It helped me a lot with cramps in legs after workout. I had a problem with cold feet and hands for whole my life. But It's drasticly reduced since I'm taking this magnesium daly. Will repurchase it over and over again.
