Product Description

Size: 8 oz. | Product Packaging: Standard Packaging

The effervescent quality of citric acid increases the bioavailability of citrate mineral.* Cal-Mag Citrate Effervescent Powder provides 500 mg calcium and 200 mg magnesium per scoop. This ratio is especially desirable for individuals who need higher amounts of calcium but who, because of magnesium's laxative-like character, cannot tolerate an equal amount of magnesium.* One scoop also provides 500 mg of vitamin C and 500 mg of the amino acid glycine.The desired amount of powder should be placed in a glass containing a small amount of water and allowed to effervesce. When it has stopped bubbling, the solution can be consumed directly or it can be further mixed with a fruit juice. The resultant calcium and magnesium include citrates, ascorbates, and glycinates.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.* *These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.

Easy to mix with other juices.

I find taking the cal-mag citrate pills much more difficult than the powder.

My mother was experiencing "leg cramps" for which her doctor provided her with pain killers. This was the wrong approach, in my humble opinion, because it obviously did not get to the root of the problem. After a bit of coaxing she agreed to visit an alternative specialist.

The new doctor, specializing in alternative medicine, suggested "Cal-Mag", an effervescent powder by Thorne Research. He said that she has a magnesium deficiency.

Less than 30 minutes after taking the product her leg cramps were gone. A week later she told me that she feels stronger and is sleeping better.

Cal-Mag Citrate is to be taken twice daily, with or without food. A toll-free phone number on the container, answered promptly by polite personnel, is provided for any particular questions you may have.

I have suffered with FIbromyalgia for years and with that accompanying leg cramps. My doctor recommended a Calcium Magnesium supplement year ago but all that I tried didn't seem to make much difference until I came across this brand. My leg cramps come mostly in the middle of the night so I take this right before bed. I add mine to orange juice because I like the taste better that way but it's not the worst on it's own. If I don't take it for a night I wake up to leg cramps again so I know it's truly the key. The shipping price seems high from all the sellers but the product is a 5-star in my book.

This product is excellent. I find taking the cal-mag citrate pills much more difficult than the powder. This is a great product, that is easy to digest and can be taken with other supplements.

I have used Cal-Mag Citrate for several months now, and am very happy with it. It was recommended by my naturopathic doctor for a complete dose of calcium.

It's actually a refreshing bedtime beverage when mixed with cold water! Taken at night, it helps with getting to sleep.

Couldn't wait for this to arrive after seeing the reviews on it and I was not disappointed. In one night there was a significant improvement in the reduction of foot and leg cramps! Two nights and they are GONE! I do not mix with any juice and the taste is do-able. I highly recommend this product for anyone who has suffered with muscle cramping, regardless of your age.

I have used this product for several years. I used to put it in a smoothie to dilute the sour taste, and it has helped with restless legs and leg cramps. After I got tired of smoothies, I switched over to Pure brand Magnesium Glycinate and wasn't taking any calcium. Recently I developed cramps in my hands, and the restless legs were barely controlled. My naturopath suggested I add 500 mg of calcium, so I dragged out the Cal Mag Citrate. I take one dose per day split between morning and evening. I find it dissolves beautifully in V-8 juice and tastes a lot like a Virgin Bloody Mary. Because that only gives me 200 mg of magnesium, I take an additional 120 mg of magnesium glycinate. Between the two I am no longer having hand or leg cramps or restless legs. Too much magnesium causes diarrhea, and this dosage appears to be just the right balance for me.
