    Getting adequate calcium and various minerals is increasingly important. Changes in the body that go along with advanced years create more of a demand for essential minerals, but obtaining adequate amounts through the diet is not always feasible. 

    Our Calcium – Magnesium – Citrate Complex with Vitamin D is a broad spectrum formulation that contains the ingredients necessary for healthy bone density and strength. Maintaining proper bone health requires more than Calcium alone. Calcium cannot be properly absorbed into the system without sufficient amounts of magnesium to help it along. Our Cal-Mag Citrate supports bone and nervous system health by providing 100% or more of these essential minerals per serving.


    Calcium and Magnesium:

    Calcium and Magnesium are essential for several functions. These minerals are critical for maintaining bone density, nerve health, muscle, and strength.

    Calcium and Magnesium work synergistically thus it is recommended in a 2:1 ratio. Although calcium plays a key role in bone mineralization and calcification, magnesium determines the quality of calcium crystal formation. In cases of magnesium deficiency, the resulting calcium crystals are weaker which can ultimately increases the risk of fracture. Calcium and magnesium also work together within muscles; calcium promotes muscle contraction while magnesium allows relaxation.



    Calcium is the most abundant mineral in the human body. Approximately 99% of calcium is stored in bones and teeth. The balance or 1% of calcium is present in the blood and fluids surrounding the cells. This mineral has several biological functions and is essential for health.

    Calcium is required for normal pH maintenance. In cases of calcium deficiency, calcium is stripped from the bones and absorbed to maintain pH balance. Calcium absorption declines with age therefore calcium supplementation is of tremendous importance for maintaining healthy bones and also slowing bone loss.

    Research Indicates:

    • Promotes strong bones and teeth
    • Helps prevent and minimize progressive bone loss
    • Helps maintain normal pH levels
    • Helps move nutrients across cell membranes
    • Important nutrient for lowering blood pressure
    • Necessary nutrient for healthy blood clotting
    • Required nutrient for muscle contraction
    • Assists and regulates in transmission of nerve impulses
    • May support healthy cholesterol levels
    • May help reduce heartburn by normalizing stomach acid
    • Plays an important role in producing hormones and enzymes that regulate digestion and metabolism


    Magnesium takes part in over 300 enzymatic reactions in body. It acts as a coenzyme for normal nerve function, normal muscle function, formation of bones, energy, and metabolism. Research has pointed out that magnesium also plays a role in proper heart function. It also works synergistically with calcium to increase its absorption and bone density. Bones store about 60% of total magnesium, 26% is found in muscles, and the remaining balance is located in other soft tissues of body. Magnesium deficiency is quite common in North America, therefore supplementation is necessary. The U.S. Department of Agriculture estimates that 75 percent of Americans do not get an adequate supply of Magnesium from their diet. Some of the reasons for deficiency include diets high in processed foods, high calcium intake, stress, intense physical activity, alcoholism, and the use of certain medications.

    Research Indicates:

    • Important nutrient for cardiovascular health
    • Necessary for healthy bone and teeth
    • Helps convert carbohydrates, proteins, and fats into energy
    • Involved in the transmission of nerve impulses and muscle contraction
    • Balances and regulates metabolism of calcium, potassium and sodium
    • Shown to inhibit formation of kidney stones
    • Required for normal muscular function
    • May support healthy cholesterol levels
    • May support healthy lung function

    Vitamin D:

    Vitamin D facilitates the absorption of calcium via the intestines. This absorption of calcium is critical to bone health as it promotes mineralization. A deficiency of Vitamin D may result in weak bones which are prone to fracture. 

    Research Indicates:

    • Important nutrient for bone health
    • Deficiency has been linked with increased hip fractures
    • May support healthy joint function
    • Vitamin D deficiency causes rickets
    • May be important for healthy immune function
    • May support overall skin health
    • Some evidence indicates that steroids may impair Vitamin D metabolism

    Frequently Asked Questions - Minerals

    • What are minerals?

      A mineral is a class of naturally occurring compounds that do not have a carbon basis. Minerals make up 60-80% of all the inorganic or non-carbon-containing material in the body. Dietary minerals help ensure the body works properly. Minerals not only build skeletal and soft tissues, they also regulate processes such as heartbeat, blood clotting, fluid pressure, nerves, muscle contractions, oxygen transport, pH balance, enzyme, and hormone systems.


      Minerals fall into two categories: macro minerals and micro minerals.  There are seven macro minerals: calcium, chloride, magnesium, phosphorus, potassium, sodium and sulfur.  They are present in virtually every cell in the body. The body requires a minimum of 100 milligrams (mg) of each per day for normal functioning and well-being.  


      Micro minerals are also described as trace minerals. They are required in smaller quantities; typically less than 100 mg per day. A few examples of micro minerals include chromium, copper, fluoride, iodine, iron, manganese, molybdenum, selenium and zinc.  

    • What is an Amino Acid Chelate?

      In 1999, the Nobel Prize for Medicine was awarded to Günter Blobel. Dr. Blobel’s dissertation stated that minerals require protein chaperones for optimal bioavailability and assimilation. Amino acid chelates are minerals that are bound to amino acids for improved bioavailability. The chelate molecules effectively push the mineral into the blood stream similar to food.

      Amino acids cross the intestinal wall with relative ease. By connecting the mineral to an amino acid it improves bioavailability. The amino acid is able to transport the mineral across the intestinal lining into the body, so it can be effectively utilized. 

    • What is Calcium and What Does it Do?

      Calcium is a mineral that is necessary for life. In addition to building bones and keeping them healthy, calcium helps muscles contractions, nerve signaling, and blood clotting. About 99 percent of the calcium in our bodies is in our bones and teeth. Each day, we lose calcium through our bodies that we can only replace with dietary sources. When we do not consume enough calcium for our body’s needs, it is taken from our bones.


      Many Americans do not get the proper amount of calcium they require daily which can lead to bone loss, low bone density, and even broken bones.


    • How Much Calcium Do You Need?

      The amount of calcium you need every day depends on your age and sex.



      Age 50 & younger

      1,000 mg* daily

      Age 51 & older

      1,200 mg* daily



      Age 70 & younger

      1,000 mg* daily

      Age 71 & older

      1,200 mg* daily

      *This includes the total amount of calcium you get from food and supplements

    • Why are vitamin D, betaine and glutamic acid in Cal-Mag-Zinc?

      Vitamin D increases calcium absorption. Betaine and glutamic acid provide assistance for proper breakdown and utilization of calcium

    • What is the Calcium and Vitamin D relationship?

      Vitamin D helps with the absorption of calcium. Most calcium supplements contain some vitamin D.

    • What is betaine HCl?

      Betaine is a metabolite of choline. It donates methyl groups, which can be important for vitamin B12 (cyanocobalamin) absorption and DNA and homocysteine metabolism. Betaine HCl is betaine with hydrochloride added to help ionize calcium for absorption.

    • What are the vegetable sources of the stearates in the Cal-Mag-Zinc Tabs?

      The calcium stearate is from limestone and the stearic acid is from palm kernel oil.

    • What citrus fruit flavors the Chewable Calcium?

      The citrus flavor is derived from oranges and pomelo (a type of citrus fruit)?

    • What are the sources of Cal-Mag Citrate Complex?

      As listed on the label, the calcium sources are the following: citrate is from citrus fruit and ascorbate is from calcium ascorbate.


      The calcium source in ascorbate is carbonate, which is derived from highly purified limestone. The starting material of ascorbate is dextrose, which is isolated from corn. Dextrose is converted to ascorbic acid through many steps. One important purifying step called crystallization removes all possible impurities and antigens. The carbonate is then bound to ascorbic acid to form calcium ascorbate. It is a highly absorbable form of calcium that provides vitamin C as a carrier.


      Note: For all our products that contain carbonate as a source of calcium, the carbonate is derived from highly purified limestone.

    • Is calcium carbonate well absorbed?

      Both the carbonate and citrate forms are similarly well absorbed, but individuals with reduced levels of stomach acid can absorb calcium citrate more easily. The body absorbs calcium carbonate most efficiently when the supplement is consumed with food. The percentage of calcium absorbed depends on the total amount of elemental calcium consumed at one time; as the amount increases, the percentage absorption decreases. Absorption is highest in doses ≤500 mg

    • Is it normal for the Cal-Mag-Zinc tabs to have a bad smell sometimes?

      The unpleasant odor is normal and does not imply an inferior product. Some of the more natural ingredients naturally are odorous. Nevertheless, our quality group takes substantial measures to ensure your materials are within specification for yeast, mold, and several other microbiological contaminants.


    • Can large doses of magnesium cause intestinal discomfort?

      Yes. Magnesium in large doses may cause intestinal discomfort. We suggest taking smaller, more frequent doses of the magnesium product.

    • Why are there scuffing marks on the Cal-Mag Chelate Tabs and other mineral tablets?

      From time to time scuffing is observed in products that contain minerals. Whenever the tablet ejects from the manufacturing equipment, the contact/rubbing of the powder with the die can causes a grayish streak. All vitamin manufactures have this issue, but most cover it up with a synthetic coating. We prefer natural tablets over synthetic coatings.

    • Why are there only 99 mg of potassium in the Potassium Tabs, 99 mg?

      Because potassium is readily available in common foods, too much supplemental potassium could cause a person to become hyperkalemic, which just means a blood potassium level that is too high. This stresses the kidneys because they are trying to excrete the potassium to keep the body in homeostasis (balance); and because potassium is an electrolyte, hyperkalemia can cause dangerously low blood pressure and irregular heartbeat. So because the side effects of too much potassium can be dangerous and life threatening, the FDA regulates how much can be consumed in supplements as 99 mg/serving, and higher doses require a doctor’s supervision by prescription.

    • Is Chromium GTF more readily absorbed than Chromium Picolinate? Is there any reason to take one form over the other? What is the difference in the two?

      Just a little history first: in the 1950’s a form of chromium was found in brewer’s yeast called GTF (Glucose Tolerance Factor) chromium and had been shown to lower plasma glucose levels in diabetic mice. This chromium form is also known as trivalent chromium, which has three chemical bonds formed by the atoms and according to studies, may provide better bioavailability although regular chromium picolinate has also been shown to be highly absorbed in the body and effective. Trivalent chromium is naturally found in egg yolks, whole grain products, brewer’s yeast, high-bran breakfast cereals, coffee, nuts, green beans, broccoli, meat, wine and beer. Chromium Picolinate is a salt of picolinic acid. Picolinic acid is made up of 6 carbons and niacin and acts as a “chelating” agent that bonds with the mineral chromium so it is absorbed properly in the body. It is important that they are paired together so good absorption takes place.


    • Was there a recent change to the tablet size of the Chelated Magnesium Tabs?

      There was a change recently. The tablets used to look scuffed and appear gray and now we added a natural colorant and increased the cellulose so the tablets are larger with no scuffed or grey appearance.


    • Where is the potassium in Potassium Tabs, 99 mg derived? Does it come from seaweed?

      It is derived from earth mining, not seaweed. The raw potassium chloride is dissolved and the resulting brine is purified

    • Is there a link between high calcium intake and kidney stones?

      At one time it was thought that a high calcium intake contributed to the development of kidney stones. However, recent studies show that a high dietary calcium intake actually decreases the risk for kidney stones. One of the main factors of kidney stones is eating foods high in oxalic acid such as spinach, collard greens, sweet potatoes, rhubarb and beans. Another factor is reduced fluid consumption. A high dietary calcium intake does not reduce calcium absorption. What may nutritionally help prevent kidney stones is to take one of our calcium supplements with magnesium. Magnesium helps keep the calcium flowing in solution inside the kidneys, so it does not form deposits.

    • What is the source of the Chelated Iron?

      Iron chelate is the rice protein based generation of mineral chelates. Enzymatically digested rice protein is selected because of its favorable bio-sensitive properties and high ratio of essential amino acids. Other beneficial nutrients are also included in balanced ratios to improve reaction affinity and enhance nutritional applications, such as citric acid, aspartic acid and glycine. The iron sources are ferrous fumarate and ferrous sulfate.
