Calcium Vitamins

Calcium, the most abundant mineral in the human body, has several important functions. More than 99% of total body calcium is stored in the bones and teeth where it functions to support their structure . The remaining 1% is found throughout the body in blood, muscle, and the fluid between cells. Calcium is needed for muscle contraction, blood vessel contraction and expansion, the secretion of hormones and enzymes, and sending messages through the nervous system . A constant level of calcium is maintained in body fluid and tissues so that these vital body processes function efficiently.

Bone undergoes continuous remodeling, with constant resorption (breakdown of bone) and deposition of calcium into newly deposited bone (bone formation) . The balance between bone resorption and deposition changes as people age. During childhood there is a higher amount of bone formation and less breakdown. In early and middle adulthood, these processes are relatively equal. In aging adults, particularly among postmenopausal women, bone breakdown exceeds its formation, resulting in bone loss, which increases the risk for osteoporosis (a disorder characterized by porous, weak bones) .

Calcium Magnesium: Biobalanced for Maximal Bone Support

Balancing calcium with magnesium is an essential part of the effort to build and maintain strong and healthy bones.

Although 99% of calcium is found in your bones, the other 1%, which circulates throughout you bloodstream, is equally important to maintaining good health. Every cell in the body needs calcium, which helps maintain proper muscle contraction and relaxation, blood clotting, nerve transmission, and heart health. Many enzymes rely on calcium to ensure proper functioning and energy production.

Vitamin D is known to be highly beneficial in helping the body better absorb and retain calcium, while supporting the transport of calcium from the blood stream to your bones.

Magnesium is a nutrient required in more than 300 biochemical reactions throughout the body and is fundamental to a number of important physical processes, including converting carbohydrates and protein into ATP (the body's primary energy source), activating B vitamins, blood clotting, and relaxing muscles. Furthermore, magnesium assists in helping the body absorb calcium and potassium.

Combined, calcium and magnesium can serve a highly useful purpose, and have the potential to be a great benefit to your overall health and well-being.

Calcium helps the heart, nerves, muscles, and other body systems work properly

Common Forms: calcium citrate, calcium carbonate, calcium gluconate, calcium lactate, calcium chloride, calcium malate, calcium aspartate, calcium ascorbate

Overview

Calcium is the most abundant mineral in the body. It is essential for the development and maintenance of strong bones and teeth; roughly 99% of calcium in the body is deposited in these two places. Calcium also helps the heart, nerves, muscles, and other body systems work properly. To function correctly, calcium must be accompanied by several other nutrients including magnesium, phosphorous, and vitamins A, C, D, and K.

The best sources of calcium are foods (see Dietary Sources), but supplements may be necessary for those who cannot meet their calcium needs through diet alone. In fact, according to the National Institutes of Health, many Americans consume less than half the amount of calcium recommended to build and maintain healthy bones. Heavy use of caffeine can diminish calcium levels; therefore, higher amounts of calcium may be needed if you drink a lot of coffee. Also, a diet high in protein can increase loss of calcium through the urine. Excessive intake of sodium, phosphates (from carbonated beverages) and alcohol, as well as the use of aluminum-containing antacids also contribute to increased excretion of calcium.

Calcium deficiency can be found in people with malabsorption problems, such as Crohn's disease, celiac disease, and surgical intestinal resection. Prolonged bed rest causes loss of calcium from the bones and the elderly are less able to absorb calcium.

Symptoms of calcium deficiency include muscle spasm or cramping, typically in hands or feet; hair loss (alopecia); dry skin and nails which may also become misshapen; numbness, tingling, or burning sensation around the mouth and fingers; nausea and vomiting; headaches; yeast infections (candidiasis); anxiety; convulsions/seizures; and poor tooth and bone development.

Uses
Obtaining adequate calcium can help prevent and/or treat the following conditions:

Osteoporosis

An inadequate supply of calcium over the lifetime is thought to play a significant role in contributing to the development of osteoporosis. Calcium is necessary to help build and maintain healthy bones and strong teeth. Studies have shown that calcium, particularly in combination with vitamin D, can help prevent bone loss associated with menopause, as well as the bone loss experienced by elderly men. If adequate amounts of calcium are not being obtained through the diet, calcium supplements are necessary.


Premenstrual Syndrome (PMS)

Calcium levels often measure lower the week prior to one's menstrual period compared to the week after. Studies suggest that calcium supplementation helps relieve mood swings, food cravings, pain or tenderness, and bloating associated with premenstrual syndrome.

High Cholesterol

Preliminary studies in animals and people suggest that calcium supplements, in the range of 1,500 to 2,000 mg per day, may help to lower cholesterol. The information available thus far suggests that keeping cholesterol levels normal or even low by using calcium supplements (along with many other measures such as changing your diet and exercising) is likely to be more beneficial than trying to treat it by adding calcium once you already have elevated cholesterol. More research in this area is needed.

Stroke

In a population based study (one in which large groups of people are followed over time), women who take in more calcium, both through the diet and with added supplements, were less likely to have a stroke over a 14 year time course. More research is needed to fully assess the strength of the connection between calcium and risk of stroke.

Colon Cancer

Although some studies are conflicting, mounting evidence suggests that people who consume high amounts of calcium, vitamin D, and milk in their diets are significantly less likely to develop colorectal cancer than those who consume low amounts of the same substances. Although it is best to obtain calcium from the diet, the suggested amounts for the prevention and treatment of colorectal cancer (namely, 800 IU/day of vitamin D and 1,800 mg/day of calcium) will most likely require supplementation.

Obesity

Both animal and human studies have found that dietary calcium intake (from low-fat dairy products) may be associated with a decrease in body weight. These effects cannot necessarily be attributed to calcium alone since dairy sources of calcium contain other nutrients (including magnesium and potassium) that may be involved in the weight loss. A review of all studies up to the year 2000 did conclude, however, that supplementation of 1,000 mg of calcium can facilitate as much as 8 kilograms (17.6 pounds) of weight loss and 5 kilogram (11 pound) loss of fat.

Dietary Sources

The richest dietary sources of calcium include cheeses (such as parmesan, romano, gruyere, cheddar, American, mozzarella, and feta), wheat-soy flour, and blackstrap molasses. Some other good sources of calcium include almonds, brewer's yeast, bok choy, Brazil nuts, broccoli, cabbage, dried figs, kelp, dark leafy greens (dandelion, turnip, collard, mustard, kale, Swiss chard), hazelnuts, ice cream, milk, oysters, sardines, canned salmon soybean flour, tahini, and yogurt.

Foods that are fortified with calcium, such as juices, soy milk, rice milk, tofu and cereals, are also good sources of this mineral.

Calcium may also be obtained from a variety of herbs, spices, and seaweeds. Examples include basil, chervil, cinnamon, dill weed, fennel, fenugreek, ginseng, kelp, marjoram, oregano, parsley, poppy seed, sage, and savory.
