Product Overview


  • Hypoallergenic
  • Dietary Supplement

Calcium and magnesium are the essentials: anthropological evidence indicates humans were high consumers of calcium until the onset of the Agricultural Age 10,000 years ago. Current calcium intake is one-quarter to one-third of our evolutionary diet, indicating we may not be consuming enough dietary calcium. Doses of well-absorbed calcium citrate-malate (that are significantly lower than what is conventionally recommended) promote bone density.

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.

The appropriate intake ratio of calcium to magnesium is undecided, with some authors in the scientific literature supporting a 2:1 ratio (twice as much calcium than magnesium) and others recommending a 1:1 ratio. Thorne Research offers several formulas with varying ratios of calcium to magnesium to meet individual needs.

Cal-Mag CitraMate provides a 1:1 ratio of calcium and magnesium as the well-absorbed citrate-malate chelate. Magnesium and calcium appear to work in tandem in the body, with both necessary for many functions, including maintaining normal blood pressure, muscle contraction, and menses. In addition to calcium, magnesium is essential for helping maintain normal bone density. Magnesium depletion impairs mineral homeostasis by reducing the activation of vitamin D.

Great Source For magnesium

This is a wonderful product that is a great value for money. Both my husband and I take it at night for good sleep and after sports.

Thanks for your feedback!

Convenient formulation for Cal Mag

Posted by iHerb Customer on Jan 01, 2017 | Verified Purchase

This seems a much more natural (and convenient) way of supplementing with calcium than taking what are essentially just chunks of chalk. Reputedly it is much more readily absorbed than the inorganic forms. As to how effective it is, that will have to wait for my next bone density scan.

Thanks for your feedback!

Good for me

Posted by iHerb Customer on Dec 08, 2016 | Verified Purchase

These definately help me especially as I'm magnesium deficient,due to fibromyalgia. if I only take 2 in the morning I start to get cramps in legs but if I also take 2 at night, it eliminates that. My holistic practitioner recommended these to me and I've been taking them fit well over a year! 2 in morning 2 at night.

Thanks for your feedback!

Superior quality ingredients at extremely reasonable prices.

Posted by iHerb Customer on Oct 05, 2016 | Verified Purchase

I have used extra nutrition to supplement normal foods for more than 40 years. In that time the nutrition business has been transformed from almost a cult status into something used by millions of sane users that often can outdo medical doctors in the nutritional knowledge field. The problem now is too much choice: How to pick good quality without spending a fortune and how to know what good quality is. My ongoing search has ended - these Thorne Research supplements are top quality yet nowhere near the highest price. But how can we tell if any vitamin/mineral is benefiting us? One way is to have a problem that is treated by the supp and improved. In my case I have a neurological ailment which is getting worse over the years and recently I started experiencing severe calf cramps when I had been asleep for 2 or 3 hours - I'm talking mega-spasm almost ripping the Achilles tendon out pain. In desperation I tried many remedies but they kept coming back -until I read a Thorne customer review where claims were made that similar pains had been stopped by taking this. Top quality Magnesium and Calcium in highly - absorbable forms . I ordered the stuff immediately and it arrived incredibly quickly and I started taking it. Night after night I still lived in fear of waking to a monster cramp but NO! No more cramps! And the price is so reasonable compared to the effect as the results are a major improvement in pain management yet these capsules are cheaper than many inferior supplements that did not work for me. And with all the other good things that these minerals do in our blood, bones, nervous system etc. it's a no-brainer; it is as essential to me as breathing is! Take it and boost your health using Rolls-Royce supplements at Ford prices. And don't forget a full spectrum of other nutrients should be taken too. Here again Thorne have made another winner!

B/P Reduced but check with your Dr to see if it is compatable with your prescribed meds

Posted by iHerb Customer on May 14, 2016 | Verified Purchase

I have had ongoing problems with my B/P for many years, I started taking 2 tabs of mag plus my prescribed tabs each day about 3 mths ago, my B/P has reduced hugely,Dr is impressed.
