Calcium: 750mg (Carbonate, Lactate, Phosphate, Sulfate, Citrate)
The highest concentration of calcium is found in milk. Other foods rich in calcium include vegetables such as collard greens, Chinese cabbage, mustard greens, broccoli, bok choy and tofu. Calcium is an essential mineral with a wide range of biological roles. Calcium exists in bone primarily in the form of hydroxyapatite (Ca10 (PO4)6 (OH)2). Hydroxyapatite accounts for approximately 40 percent of bone weight. The skeleton has a structural requisite and acts as a storehouse for calcium. Apart from being a major component of bones and teeth, calcium supports normal muscle contraction, nerve health, heart rhythms, blood coagulation, glandular secretion, energy production and immune system function.* Sufficient daily calcium intake is necessary for maintaining optimal bone density, healthy bones and teeth and has been shown to ease the discomfort of PMS in women. When the body does not get enough calcium per day, it draws calcium from your bones. The amount of calcium in the blood is regulated by PTH (parathyroid hormone). High levels of calcium in the body correlate with normal cardiovascular health and normal cholesterol levels. In the American Dietetic Association Journal a study revealed that calcium helped middle-aged women to maintain healthy weight levels.*

Magnesium: 200 mg (Oxide, Carbonate)
Foods rich in magnesium include unpolished grains, nuts and green vegetables. Green leafy vegetables are potent sources of magnesium because of their chlorophyll content. Meats, starches, dairy products and refined and processed foods contain low amounts of magnesium. The average daily magnesium intake in the U.S. for males nine years and older is estimated to be about 323 milligrams; for females nine years and older, it is estimated to be around 228 milligrams. Recent research shows that our diets are magnesium deficient. Magnesium is a component of the mineralized part of bone and supports the normal metabolism of potassium and calcium in adults. It helps maintain normal levels of potassium, phosphorus, calcium, adrenaline and insulin. It also supports the normal transport of calcium inside the cell for utilization. Magnesium promotes the normal functioning of muscle and nervous tissue and the normal synthesis of all proteins, nucleic acids, nucleotides, cyclic adenosine monophosphate, lipids and carbohydrates. Magnesium helps combat oxidative stress and lipid peroxidation. Magnesium supports normal energy release, regulation of the body temperature, nerve function, adaptation to stress, and metabolism. Importantly, magnesium also supports the body’s ability to build healthy bones and teeth and develop muscles. It works together with calcium and vitamin D to help keep bones strong. Magnesium, when combined with calcium, helps support the heart muscle, helps maintain a regular heartbeat and helps maintain normal blood pressure.

Manganese: 1 mg (Sulfate)
Manganese is a mineral found in large quantities in both plant and animal matter. The most valuable dietary sources of manganese include whole grains, nuts, leafy vegetables and teas. Manganese is concentrated in the bran of grains, which is often removed during processing. Only trace amounts of this element can be found in human tissue. Manganese is predominantly stored in the bones, liver, kidney and pancreas. It supports the normal formation of connective tissue, bones, blood-clotting factors and sex hormones. It supports normal fat and carbohydrate metabolism, calcium absorption and blood sugar regulation. Manganese also promotes normal brain and nerve function. Manganese is a component of the antioxidant enzyme manganese superoxide dismutase (MnSOD). Antioxidants scavenge free radicals that can cause premature aging and oxidative stress to the body. These particles occur naturally in the body but can possibly contribute to the aging process. Antioxidants such as MnSOD can neutralize free radicals. Some experts estimate that as many as 37% of Americans do not get the recommended daily amounts of manganese in their diet. This may be due to the fact that whole grains are a major source of dietary manganese, and many Americans consume refined grains more often than whole grains. Refined grains provide half the amount of manganese as whole grains.

Vitamin B2: 4 mg (Riboflavin-5-Phosphate)
Vitamin B2 is a found in liver, dairy products, dark green vegetables and some types of seafood. Vitamin B2 serves as a co-enzyme, working with other B vitamins. It promotes healthy red blood cell formation, supports the nervous system, respiration, antibody production and normal human growth. It supports healthy skin, nails, hair growth and promotes the normal regulation of thyroid activity. Vitamin B2 supports the normal process of turning food into energy as a part of the electron transport chain, driving cellular energy on the micro-level. Riboflavin can be useful for pregnant or lactating women as well as athletes due to their higher caloric needs. Vitamin B2 supports the normal breakdown of fats while promoting the normal activation of B6 and folic acid. Vitamin B2 is water-soluble and cannot be stored by the body except in insignificant amounts. It must be replenished daily. Under some conditions, vitamin B2 can act as an antioxidant. The riboflavin coenzymes also support the transformation of vitamin B6 and folic acid into their active forms and for the conversion of tryptophan into niacin.

Vitamin C: 58 mg (Ascorbic Acid)
The best food sources of vitamin C include all citrus fruits (oranges, grapefruit, lemons and tangerines), strawberries, tomatoes, broccoli, brussel sprouts, peppers and cantaloupe. Vitamin C is a "fragile" vitamin and can be easily destroyed by cooking or exposure of food to oxygen. Vitamin C promotes a vitamin "sparing" effect, supporting your body’s ability to utilize multiple vitamins and minerals such as thiamin, riboflavin, pantothenic acid, biotin, folic acid, B12, retinaldehyde and alpha-tocopherol and the mineral calcium. It's also a cofactor or supporter in the normal metabolism of folic acid, some amino acids and hormones. Being an effective antioxidant, it also supports iron absorption from the small intestine. Vitamin C supports vitamin E in cell membranes. It supports the normal synthesis of collagen. Vitamin C supports cardiovascular health, normal cholesterol levels and supports a healthy immune system. Vitamin C has become the world's most popular vitamin. One reason is its ability to support the immune system. The most convincing evidence suggesting the need for vitamin C supplementation is based on the fact that humans are incapable of producing vitamin C in their bodies. Low intakes of vitamin C are common in the United States. Stress may also account for reduced vitamin C levels in many Americans. Smoking and some drugs may also impair the body's ability to absorb vitamin C. Since it is water-soluble, vitamin C is flushed from the body each day. Since humans don't always eat foods containing an adequate amount of vitamin C, it often is beneficial to take a supplement.

Vitamin D3: 25 mcg  (Cholecalciferol)
Regular sunlight exposure is the main way that most humans get their vitamin D. Food sources of vitamin D include vitamin D-fortified milk (100 IU per cup), cod liver oil, and fatty fish such as salmon and small amounts are found in egg yolks and liver. Vitamin D promotes the absorption of calcium and phosphorus and supports the production of several proteins involved in calcium absorption and storage. Vitamin D works with calcium to promote strong, hard bones. It supports normal transport of calcium out of the osteoblasts into the extra-cellular fluid and in the kidneys. It also promotes normal calcium and phosphate re-uptake through the renal tubules and intestinal epithelium. It supports normal skin cell growth and promotes normal producing of insulin by the pancreas.

Potassium: 220 mg (Bicarbonate, Citrate)
Potassium is an electrolyte stored in the muscles. Foods rich in potassium include bananas, oranges, cantaloupe, avocado, raw spinach, cabbage and celery. Potassium is an essential macromineral that helps maintain fluid balance in the body. It also plays a role in a wide variety of biochemical and physiological processes. Among other things, Potassium supports the normal transmission of nerve impulses, contraction of cardiac, skeletal and smooth muscle, production of energy, synthesis of nucleic acids, maintenance of intracellular tonicity and maintenance of normal blood pressure. In 1928, it was first suggested that high potassium intake could help maintain cardiovascular health. Potassium supports normal muscle relaxation and insulin release. It also promotes glycogen and protein synthesis. Potassium is an electrolyte that promotes normal heartbeat. Potassium is important in releasing energy from protein, fat and carbohydrates during metabolism. Potassium supports the body’s ability to regulate water balance, recover from exercise and eliminate wastes. Some symptoms of potassium deficiency include poor circulation, swelling, sleep difficulty, intestinal discomfort, muscle weakness and water retention. Sodium and potassium are two of the most important ions in maintaining the homeostatic equilibrium of the body fluids.

How much calcium should I take?
The National Academy of Sciences has established guidelines for calcium that are 25-50% higher than previous recommendations. For ages 20 to 50, calcium consumption is recommended to be at least 1,000 mg daily; for adults over age 51, the recommendation is 1,200 mg daily. The most common supplemental amount for adults is 800 to 1,000 mg per day. Some physicians recommend 1,000 milligrams of supplement calcium daily for postmenopausal women taking estrogen replacement therapy (ERT) and 1,500 milligrams daily for postmenopausal women not taking ERT. Everyone should be getting appropriate calcium intake. The Food and Nutrition Board of the Institute of Medicine of the U.S. National Academy of Sciences has recommended the following adequate intakes (AI) for calcium. Examine the table provided in order to determine appropriate calcium intake requirements*:

Infants (from breast milk or formula)

I'm not an elderly woman. Why should I take a calcium supplement? Calcium plays a huge role in regulating many major bodily processes with implications that extend far beyond the age factor. Other than elderly women who may be susceptible to bone loss, younger women, pregnant and lactating women, growing children and men should take a calcium supplement. Younger women need more calcium to build up the strength of their bones. Pregnant and lactating women need extra calcium, at least 1200 mg /day to foster the healthy growth of new cells and of breast milk. Growing children need extra calcium, sometimes two to four times as much as an adult to assist with new bone development and proper growth. Finally, those with poor cardiovascular health have been found to have low levels of calcium intake. Studies have confirmed that calcium supplementation supports heart health.*

Why should I take calcium? According to the Surgeon General, taking a calcium supplement daily is key to preventing and treating calcium deficiency and to helping reduce the risk of osteoporosis. Currently, osteoporosis affects over one-third of postmenopausal women in this country. Recent clinical statistics also indicate that aging men are also likely to become susceptible to osteoporosis.* Everyone needs calcium. Practically no one ingests enough calcium in their daily diet. Besides being helpful in supporting and maintaining bone integrity, calcium serves a dynamic role as a mineral. It's very important in supporting the activity of many bodily enzymes and maintaining proper fluid balance. nutraMetrix® Isotonix® Calcium Complete also promotes the normal contraction of skeletal and muscle.

I've heard calcium is great for PMS? How so? PMS is an undesirable influence on physical and psychological peace of mind. Recent studies have found that over 70 percent of relationships are affected in some way by PMS. So PMS impacts nearly everyone, including men! Supplementation with calcium can reduce PMS symptoms. In a study conducted by the US Department of Agriculture's Human Nutrition Research Center, it was found that women on a high calcium diet had decreased irri">What is the suggested age to begin taking nutraMetrix Isotonix® Calcium Complete? nutraMetrix® Isotonix® Calcium Complete is recommended for all adults age 18 or older.

If we only absorb 300 to 400 mg of calcium at a time, why does one capful contain 750 mg? There are 750 mg of Calcium in 2 capfuls of nutraMetrix® Isotonix® Calcium Complete. Therefore, one capful equals 375 mg of Calcium.

Why is nutraMetrix® Isotonix® Calcium Complete better than other calcium products? It is better because of the Isotonix delivery system. The secret of the isotonic process is probably now becoming clear! When an isotonic substance enters the body, it will be absorbed into the bloodstream rapidly. With isotonic fluids, little nutritive value is lost making the absorption of nutrients highly efficient. There is nothing artificial about it. An isotonic fluid is nature's own nutrient delivery system.

Why is there a sandy residue left in the cup after mixing with water? Everyone's water is different; some tap water has a higher concentration of minerals and the pH level of water differs depending on geographic location and the quality of the tap water, which can lead to inconsistencies with the saturation point of a solution. To ensure that our solutions reach the point of saturation, regardless of the pH or mineral levels in water, we have maximized the formulation amounts so that every serving of Isotonix Calcium Complete contains the correct amount of calcium. The residue left in the cup is due to over-saturation which is common in tap water with a higher pH level or a higher mineral content.

What form of calcium should I take? The best form of calcium is calcium carbonate which is utilized by the body more efficiently, due to the fact that it increases the absorbability. Additionally, calcium is more readily absorbed by the body when in combination with magnesium, manganese, vitamin C, vitamin B2, boron and potassium. nutraMetrix® Isotonix Calcium Complete is formulated with calcium carbonate and the additional vitamins and minerals needed in an isotonic form which allows for maximum utilization and absorption of calcium by the body and reduces the nutritive loss found in many calcium tablets or capsules.
