Calcium lactate and calcium aspartate are also well-absorbed. calcium carbonate may cause side effects such as nausea, gas and constipation; but taking it in divided doses with meals may reduce these side effects and improve absorption.25 When to take calcium supplements Absorption of calcium from supplements is considerably reduced in people who have low stomach acid unless the supplements are taken with food.

A 1989 study showed that a light meal improved calcium absorption from milk, calcium carbonate and calcium-citrate-malate sources.26 However, calcium may decrease the absorption of other minerals such as zinc. Some calcium supplements can interfere with iron absorption, although this does not seem to be the case with calcium citrate and calcium ascorbate as they are acidic. Some experts advise taking two-thirds of the daily calcium dose at bedtime and the rest in the morning. Others recommend dividing the dose into four parts; i.e. with meals and at bedtime.

The calcium citrate form of supplement is less likely to cause kidney stones than calcium carbonate. QUICK GUIDE Essential for normal sugar and fat metabolism because it is part of a compound known as glucose tolerance factor (GTF) Absorption and metabolism Absorption of chromium from food is poor. Deficiency Symptoms include high blood fat and cholesterol levels, glucose intolerance and other diabetes-like symptoms. Marginal deficiency may play a role in the development of diabetes and heart disease. Sources Good sources include liver, eggs, poultry and whole grain cereals.

They contain different amounts of calcium and are available in various forms including calcium carbonate (which contains 40 per cent calcium), calcium aspartate, calcium citrate (21 per cent calcium), calcium gluconate (9 per cent calcium) and calcium lactate (13 per cent calcium). While multivitamins do contain some calcium, the amount is not usually sufficient to meet daily requirements and separate calcium supplements are more useful.

INSTRUCTIONS Generally, calcium supplements should be taken with meals for best absorption, but not with iron supplements. calcium carbonate may be constipating in some people, but other calcium salts are less likely to cause this problem. INTERACTION Calcium salts have been used in some cases of verapamil overdose or toxicity to reduce the effects of this calcium channel blocker. It is not clear if daily doses of calcium will modify the effectiveness of verapamil. Tell your doctor if you plan to start or stop calcium supplements so that your clinical response can be monitored.

Cream depilatories that act by dissolving the hair usually contain calcium thio-glycolate, calcium carbonate, calcium hydroxide, cetyl alcohol, sodium lauryl sulfate (a detergent), water, and a strong perfume (so as to remain stable in an alkali medium). Another type of depilatory made of wax acts by hardening around the hair and pulling it out. Such products usually contain rosin, beeswax, paraffin, and petrolatum.

INTERACTIO Thiazide diuretics such as those listed on this page conserve calcium by modifying the way the kidneys eliminate this mineral. This action might be beneficial against osteoporosis and fractures. A problem may arise, however, if someone also took large amounts of calcium and vitamin D.

Staying Healthy with Nutrition: The Complete Guide to Diet and Nutritional Medicine

Elson M. Haas, M.D. (See book keywords and concepts)

The word calcium comes from the Latin calc, meaning "lime," as in limestone, a calcium carbonate substance.) Dolomite, a calcium-magnesium earth mineral combination that is a little more soluble and usable by the body than some other forms, is a commonly used calcium supplement. Many other nutrients, vitamin D, and certain hormones are important to calcium absorption, function, and metabolism. Phosphorus as well as calcium is needed for normal bones, as are magnesium, silicon, strontium, boron possibly, and the protein matrix—all part of our bone structure.

Frequently, calcium lactate or calcium carbonate (such as Turns) pills—which are more alkaline and slowly absorbed—are prescribed without suggesting additional vitamin D and magnesium, so important for calcium balance and metabolism. A woman who needs more calcium could be taking an extra gram a day without really getting much of it into her blood or bones. In general, calcium absorption becomes less efficient as we age. During infancy and childhood, 50-70 percent of the calcium ingested may be absorbed, whereas an adult might use only 30-50 percent of dietary calcium in his or her body.

Various calcium formulae, such as calcium carbonate and calcium gluconate, are taken commonly as dietary supplements to attain adequate calcium levels. Many calcium salts are used as nutrient additives in enriched foods, especially grain products—cereals, flours, infant formulas, cornmeal, farina, noodles, and breads. Calcium salts are also used as emulsifiers in evaporated milk, frozen desserts, and breads; as dough conditioners in baked goods; and as clarifying agents in sweets.

Some calcium salts, such as calcium carbonate, oxide, and hydroxide, are used as antacids and as buffering agents in milk products, for example, to help control acidity. Calcium lactate is used as a buffer in baking powder. Some salts, such as calcium chloride, gluconate, and hydroxide, act as firming agents. These may be used in jellies or in canned fruits, tomatoes, or potatoes. Calcium sulfate can act as a carrier for bleaches and is used in the brewing industry. Problems from use of the many calcium salts are very unlikely.

Buffers and neutralizers help to adjust or maintain the acid-base balance of foods. calcium carbonate, sodium aluminum phosphate, potassium tartrate, and ammonium bicarbonate are some examples. Bleaching and maturing agents. Most of these are used in flour products and sometimes in cheeses. Bleaching agents such as benzoyl peroxide and chlorine dioxide are used to help oxidation and speed the whitening of fresh-ground flour. These chemicals also act as maturing agents and are sometimes called "bread improvers." Chlorine, nitrosyl chloride, and oxide of nitrogen are some other food bleaches.

Use of high doses of calcium carbonate and sodium bicarbonate at the same time can lead to milk-alkali syndrome. Symptoms are headache, nausea, irritability, weakness, electrolyte imbalances and kidney damage. Long-term use of aluminum-containing antacids can lead to phosphate depletion (hypophosphatemia) if intake of this mineral isn't adequate. Hypophosphatemia can lead to loss of appetite, exhaustion, weakness and bone problems. Antacids can deplete calcium levels. Using antacids such as Turns as a source of calcium is not useful, since at best it will replace what the antacid is blocking.

Individuals with acmornyana aDSoro caicium irom caiciuiu caiuonaic puony unless the calcium carbonate supplement is taken with food. Calcium that is unabsorbed from the intestine is excreted in the feces. Greater than 98% of calcium from the glomerular filtrate is reabsorbed. Renal reabsorption is primarily regulated by parathyroid hormone or PTH. The colon plays an important role in calcium absorption after resection of the small intestine.

Low molecular weight complexes, such as calcium carbonate, may be absorbed intact. As calcium intakes increase, the active transfer mechanism becomes saturated and an increasing proportion of calcium is absorbed via passive diffusion. The absorption efficiency of calcium varies throughout the life span. It is highest during infancy when it is about 60%. In prepubertal children, it is about 28%. During early puberty, at the time of the growth spurt, it increases to about 34% and then drops to 25% two years later where it remains for several years.

All subjects also received 1 gram of calcium carbonate. The ipriflavone-treated women showed a significant increase of vertebral bone density at the end of the treatment period. The placebo group presented a significant decrease of vertebral bone density. In addition, urinary HOP/Cr, a measure of bone loss, was significantly decreased, suggesting a reduction in bone turnover rate. There was also a reduction in the incidence of vertebral fractures in the ipriflavone-treated group as compared to placebo (Agnusdei et al. 1997a).

A clinical pilot study noted encouraging results in elderly women given supplements of GLA, eicosapentaenoic acid (EPA) along with calcium carbonate. Those treated experienced increased lumbar and femoral bone mineral density over 36 months. There is some evidence that prolonged use of GLA may result in reduced blood pressure in some hypertensive individuals, as well as fewer coronary events. These effects warrant further investigation. There is some evidence that higher doses of GLA than typically used may improve blood lipids. In a small study, 17 subjects were assigned to two groups.

Calcium citrate is generally better absorbed and utilized than calcium carbonate. Calcium bis-glycinate absorbs even better than calcium citrate. Daily intakes should reach at least 1000 mg of calcium and 500 mg of magnesium, along with sufficient trace minerals including zinc, boron, and copper. 2. For bone mineral maintenance and replacement, the Life Extension Foundation recommends that women take between 1000-2000 mg of elemental calcium along with 600-1000 mg of elemental magnesium every day.

Different calcium compounds have different levels of bioavailability. calcium carbonate is 40 percent calcium, but other forms of calcium contain considerably less. Look for the words calcium or elemental calcium on the label. Check for selenium. For years some researchers have touted this trace mineral as a cancer preventive. That view gained considerable credence when the NCI's study in China showed that it helped prevent deaths from esophageal and stomach cancer. Vegan vegetarians may need extra B12. If you consume no animal products, you may become deficient in vitamin B12.

Natural calcium sources include bone meal and dolomite, both of which may be contaminated with lead, a highly toxic heavy metal that impairs thinking and can cause mental retardation in children. calcium carbonate, a laboratory creation, is the way to go. Don't get taken in by hype. Want more energy? Stress management? Sexual ecstasy? Longevity? Immune enhancement? Freedom from illness? Some supplement labels promise their products can do everything except raise the dead—and maybe that too, if you take enough.

The Natural Physician's Healing Therapies

There are some supplements that can interfere with the absorption of iron, including calcium carbonate, magnesium, and zinc—so don't take them at the same time you're taking iron. Antibiotics can also interfere with absorption: If you have a prescription, take it as recommended, but wait at least a couple of hours before you take iron. Plant foods have phytates, which can also decrease absorption, so you'll get more benefit from the iron supplement if you don't take it immediately before or soon after a meal. Some iron supplements are much more well-absorbed than others.

The carbonate form is not so well absorbed and it buffers stomach acid—that is, gets in the way of the stomach acid that's needed for calcium absorption. If calcium carbonate is used, then higher amounts are required due to the decreased absorbtion. Make sure to use a reputable brand, as some calcium supplements have been found to be contaminated with lead. Avoid dolomite and bone meal: These calcium supplies are poorly absorbed, and some sources have a history of lead contamination. I recommend most adults and children take 500 to 1,000 milligrams daily of a good-quality calcium supplement.

A six-year Harvard study of 48,000 male physicians found that men who consumed tomato-rich foods (tomatoes, tomato sauce, and pizza) at least ten times a week had a 35 percent decreased risk of prostate cancer as compared with those men who ate less than 1.5 weekly servings."

The dried, crushed leaves are then mixed with water and calcium carbonate or lime to produce an alkaline reaction. The mixture is next crushed, with kerosene or gasoline added, while everything is thoroughly stirred with wooden paddles. After the leaf pulp is discarded, the kerosene is mixed with acidified water, and the aqueous layer is separated and made alkaline with ammonia or baking soda. This precipitates a thick, aromatic paste containing not only cocaine, but also several other alkaloids. The smoking of coca paste has become a drug abuse problem in peru, Bolivia, Colombia, and Ecuador.

Gastric acid must be present in the stomach for the proper absorption of some forms of calcium, in particular the calcium carbonate form. A lack of sufficient stomach hydrochloric acid could occur in a number of medical conditions; most notably, there may be a marked reduction of stomach acid in people taking large doses of antacid medications or taking acid-inhibiting drugs for ulcers. Such drugs would include Tagamet (cimetidine), Zantac (ranitidine), and Pepcid (famotidine). However, this association is not true across the board according to a study done by T. A.

Interactions— • calcium carbonate (a form of calcium often used in over-the-counter calcium supplements) can impair your ability to absorb chromium and could ultimately cause you to become deficient. • Sugar increases your need for chromium and at the same time may increase your loss of chromium in urine. • Do not take supplemental chromium if you have diabetes. Chromium can affect insulin requirements. Recommended Usage—Use only the chromium picolinate form to take the DRI dosage of 120 micrograms daily. Picolinate enables chromium to enter the body's cells more effectively.

The human ear contains numerous otoliths—minute grains of calcium carbonate crystals that react with cilia (hair-cell receptors) in accordance with motion (Tusa 2001). As we move, these receptors are stimulated to relay positional information to the brain. Normally these crystals are held in place by the gelatinous extracellular matrix of the ear's utricle, but under certain circumstances, such as age-related degeneration, head trauma (Gordon et al. 2002), or viral infection, these otoliths may become free-floating bodies (Schmal et al. 2002).

The nature of the calcium salt used in these preparations is also of major significance, because calcium carbonate is not well absorbed in older patients when gastric HCL production is decreased. Calcium citrate, bisglycinate, and microfine calcium hydroxyapatite should be used preferentially. Two excellent comprehensive bone supplements include Bone Assure from Life Extension Foundation and Bone Up from J arrow. It is important for the PPP team to undetstand the importance of these substances in bone physiology and their interactions with other cellular processes.
