Product Description

Size: 250

Calcium and magnesium work together in several key physiological processes. They are important in the regulation of blood pressure and are responsible for healthy muscle function. Calcium is needed for muscle contraction and magnesium for muscle relaxation. In addition, they are both components of skeletal tissue, and magnesium is necessary for calcium’s absorption into the bones

This is a great product. As long as I take it with food it does not upset my stomach or cause digestive upset. It is a great help with relieving muscles spasms. The only issue is that the product is not labeled correctly here on Amazon.

The bottle I received reads: 1 Tablet contains 500 IU Vitamin D-3 (as cholecalciferol), 200 mg Calcium (amino acid chelate) and 100 mg Magnesium (amino acid chelate).

The product description says there is 250 mg Calcium, 125 mg Magnesium.... which would lead one to believe that you are getting a more potent formula than what is available at other sellers. Source Naturals does not advertise a 250/125 formula on the company website.

Bottom line, it's a great product, but I didn't recieve what was advertised.

Magnesium is an important nutrient for the proper functioning of our bodies. Some of the benefits of Magnesium include contraction and relaxation of muscles along with production of protien. Calcium serves to keep our bone and teeth strong along with the proper functioning of our muscles and nerves.

I have been using the Source Naturals brand for several years now and chose this particular product because of my past positive experience with other supplements made by Source Naturals along with the good deal on Amazon. This product contains no preservatives, artificial colors/flavors, or fragrance.

I tend to workout a lot and not always get enough of my daily supply of leafy/dark greens, peas/beans, or whole grains. The bottle suggests 1-3 tablets daily with food. I tend to take between 1-2 daily depending how much vegetables/fruits I've eaten. I take my first early in the day. Then I'll take a second one later in the day if I haven't eaten enough of the quality stuff. Overall this product has been easy for my body to process.

This apparently had an immediate beneficial impact. We bought this item and a chelated B complex supplement Integrative Therapeutics - NEW Active B-Complex - 60 veg. caps (FFP) for grandpa. Grandpa immediately felt better and his hair on his head immediately began growing again. Grandpa does not have male pattern baldness, but he had lost almost all of his pate hair, and what remained was white. Within a week many more pate follicles were growing hair. Though less hair than when he was young, grandpa now has 100 or 1000 times more pate hair and it is black again. We have been buying vitamin supplements for grandpa for many years, including calcium, magnesium, D3, B complex, and B-12, and none of those worked like these did. We had been buying the magnesium as the oxide, and the low cost Bs.

After I read a medical article on how badly your body processes calcium carbonate and calcium citrate I went looking for a better supplement that was reasonably priced. Source naturals fit the bill. I take 2 tablets at night (with my other pills). I've had no bad side effects.
A great side effect was that I was able to stop taking prescription Vitamin D. I've had problems with Vitamin D blood serum levels all my life (hereditary). I was taking 22000 IU, prescription. After a year of this I was off all prescription D with healthy blood levels. Didn't expect that, but amazing bonus. (I have blood tests every 3-4 months. Don't ever do anything your doctor doesn't tell you to!)

honking big tablets, not gelatin capsules. If you've got swallowing problems, count on needing to break these up. That said, this supplement does the job for a good price. Helped clear up my joint, muscle and nerve aches in just a few days! On my Subscribe and Save schedule. Get some!

Can't really ask for more on the ingredients, the best form of the minerals in a good ratio, D3 is a nice plus, and a minimal amount of binders. My only complaint, is the size of the pills, these things are on the horse-pill side, at least they are well coated and shaped well so they can be swallowed okay, but I have gotten it stuck more than once and that can be painful.

I started taking these in hopes that my teeth would be less sensitive. Just so happens that Biotene Toothpaste changed their formula at the same time. Needless to say, my teeth are much better. I also notice that I feel less tense when I take them, could just be psychological, but I like them. No negative side effects.

I have no stomachs problems taking this pill but this product does contain soy which is disappointing since the pictures of this item does not show that it contains soy which I try to avoid.
