The Benefits of Calcium
Calcium and Weight Loss: A two-year study found
young women who had the highest intakes of calcium from dairy
foods lost the most weight and adipose fat on weight control
programs, regardless of exercise level. (Teegarden D, et
al. J Am Coll Nutr; 19: 754-60, 2000). Limited epidemiological
and experimental data support the possibility that dietary
calcium intake plays a role in human body weight regulation.
(Parikh SJ; Yanovski JA.Calcium intake and adiposity. Am
J Clin Nutr; 77(2): 281-7, Feb 2003). Data from six observational
studies and three controlled trials in which calcium intake
was the independent variable (and either bone mass or blood
pressure the original outcome variable) were analyzed to
evaluate the effect of calcium intake on body weight and
body fat. Analysis revealed a consistent effect of higher
calcium intakes, expressed as lower body fat and/or body
weight, and reduced weight gain at midlife. (Heaney, R.P.,
Davies, K.M., Barger-Lux, M.J., "Calcium and Weight: Clinical
Studies," Journal of the American College of Nutrition, 21(2),
pages 152S-155S, 2002).
Calcium and Colon Cancer: Colon cancer claims 134,000
victims and causes about 55,000 deaths each year in the United
States. Epidemiological evidence suggests that dietary levels
of calcium and vitamin D intake are inversely related to
the incidence of colon cancer. (Holt, P.R. et al.J.A.M.A.
, 280 (12) 1074-9,1998). Data from the Nurses' Health and
Health Professionals Follow-up studies (88,000 women and
47,000 men, respectively) were analyzed to examine the effect
of calcium intake on risk of colon cancer. At a 16 and 10-year
follow-up for the two studies, 626 women and 399 men had
developed colon malignancies. Those who consumed 700-800mg
calcium daily, from diet or supplements, had a 40-50% lower
risk of developing colon cancer than those with intakes under
500 mg/day. (Wu K, et al. J Natl Cancer Inst; 94:437-46,2002).
Animal studies conducted in Japan concluded Coral Calcium
exerted an inhibitory effect on the metastases of the cancer
cells to the lungs by activating natural killer (NK) cells
and macrophages, thus resulting in preventing the proliferation
of cancer cells. (Yuji Hirota, Ph.D. and Takashi Sugisaki,
Ph.D. Effects Of The Coral Calcium As An Inhibitory Substance
Against Colon Cancer And Its Metastasis In The Lungs. Nutrition
Research, Vol. 20, No. 11,pp. 1557-1567, 2000).
Calcium and Tooth Loss: People with low intakes
of dairy foods, that is under 1.5 servings per day, have
almost twice the risk of periodontal disease leading to tooth
loss than those consuming at least three serves per day.
Note that the study refers to calcium intake, not specifically
dairy products, although they are the principal dietary source
of calcium. (Nishuda M et al: Calcium and the risk for periodontal
disease. J Periodontol; 71:1057-1066,2000).
Calcium for Hypertension: A double-blind randomized
placebo-controlled trial involved 116 adolescents to determine
whether an increased intake of calcium can lead to a reduction
in blood pressure. Subjects were given 1.5g/day of calcium
or placebo. Results confirmed that there was a decrease in
diastolic blood pressure in the group receiving a calcium
supplement. The effect was greater in those whose diets were
low in calcium. (Am. J. Clin. Nutr. 68 (3) 648-655, 1998).
Calcium and Vision: Maintenance of calcium levels
is critical to cell function. Loss of calcium homeostasis
might be a contributing factor to the development of cataracts
in the lens. (Liu L; Paterson CA; Borchman D.Regulation of
sarco/endoplasmic Ca2+ -ATPase expression by calcium in human
lens cells. Exp Eye Res; 75(5): 583-90. Nov 2002).
Calcium and Brain Function: Calcium plays a role
in neural information processing. (Egelman DM; Montague PR.
Calcium dynamics in the extra cellular space of mammalian
neural tissue. Biophys J; 76(4): 1856-67, Apr 1999).
Calcium and Wound Healing: Calcium has an established
role in the normal homeostasis of mammalian skin and serves
as a modulator in keratinocyte proliferation and differentiation.
(Lansdown AB.Calcium: a potential central regulator in wound
healing in the skin. Wound Repair Regen; 10(5): 271-85, Sep-Oct
2002).
Calcium and Heart Disease: The major spark for the
rhythmic excitation of the heart, which ignites roughly every
second normal heart rate is about 60-70 beats per minute is
created by the sodium current flowing through a pore in the
cell membrane, the so-called sodium channel. And the squeeze the
mechanical contraction that expels the blood is due to
elevation of intracellular calcium that triggers the contractile
mechanism in the heart. (Dr. Jeffrey R. Balser. Arrhythmias
linked to calcium levels. Nature study directed by VUMC Anesthesiology.January
25, 2002).
Calcium and Kidney Stones: Calcium supplements cause
oxalate to bind while in the stomach, before it can be absorbed
into the urinary tract. This causes a decrease in urinary
oxalate, which reduces the risk of kidney stones. While increased
calcium in the urine may cause some kidney stones, overall
higher calcium intake appears to lower kidney stone formation
risk. (Marshall RW, Cochran M, Hodkginson A. Relationship
between calcium and oxalic acid intake in the diet and their
excretion in the urine of normal and renal-stone forming
subjects. Clin Sci; 43:919, 1972 and Curhan GC, Willett
WC, Rimm EB, Stampfer MJ. A Prospective study of dietary
calcium and other nutrients and the risk of symptomatic kidney
stones. N Engl J Med; 328:8338,1993).
Calcium and Cholesterol: Calcium binds fats and
prevents their absorption by the body. Possibly as a result
of this, calcium also reduces cholesterol levels. (Yacowitz
H, Fleischman AI, Bierenbaum ML. Effects of oral calcium
upon serum lipids in man. BMJ; 1:13524, 1965 and Jorde R;
Sundsfjord J; Fitzgerald P; Bonaa KH. Serum calcium and cardiovascular
risk factors and diseases: the Tromso study. Hypertension;
34(3): 484-90, Sep 1999).
Calcium and Migraines: Vitamin D when used with
Calcium provides some relief for migraines. (Thys-Jacobs
S. Alleviation of migraines with therapeutic vitamin D and
calcium. Headache; 34(10): 590-2, Nov-Dec, 1994).
Coral Calcium as a Bone Graft Substitute: Coral
is naturally synergistic with the human body. This is evidenced
by the medical practice of using pieces of coral in bone
graphs. Orthopedic surgeons use coral in bone graphs because
the body readily accepts the coral and the various muscles
and tendons grow into the coral structure as if it were actual
human bone. Surgeons have packed the cracks and wholes in
broken bones of the elderly with the coral paste made from
coral calcium and water. (Demers C, Hamdy CR, Corsi K, et
al.Natural coral exoskeleton as a bone graft substitute:
a review. Biomed Mater Eng (Netherlands), 12(1) p15-35, 2002
and Soost F, Reisshauer B, Herrmann A, et alMund Kiefer Gesichtschir
. Natural coral calcium carbonate as alternative substitute
in bone defects of the skull. Mund Kiefer Gesichtschir (Germany),
2(2) p96-100, March 1998).
Calcium and Ulcers: Ancient man found that heartburn
could be relieved by ingesting minerals that had antacid
properties. Calcium carbonate was one of the first of these,
as it occurred in relatively pure form in coral and limestone.
Antacids were the keystones of medical management until the
modern era of ulcer treatment. There has been a renewal of
interest in antacids in recent years. Calcium as a component
of the diet has come under scrutiny. Antacids have been found
to be as effective in promoting healing of ulcer as H2 antagonists,
sulcrafate, and colloidal bismuth. (Texter EC Jr. A critical
look at the clinical use of antacids in acid-peptic disease
and gastric acid rebound. Am J Gastroentero; 84(2): 97-108,Feb
1989).
Calcium and Allergies: Increased concentration of
intercellular calcium ion in the granular leukocytes may
have anti-inflammation functions in patients with allergic
rhinitis. (Shen Z; Wang H; Wang H; Lin J; Chen Y; Song D
The effects of BDP on calcium ion in the granular leukocytes
in nasal secretions of the patients with allergic rhinitis.
Lin Chuang Er Bi Yan Hou Ke Za Zhi; 16(1): 25-6, Jan 2002).
Where does MD Healthline coral come from?
As a result of geophysical changes over thousands of years,
coral is lifted above sea level. The harvesting process involves
removal of the protective layer of soil that accumulated
over time and collecting the ancient coral. The environmental
consequences are minimal and are similar to any small land
based mining operation. There is some evidence that the mining
may actually benefit the live reefs.
Why MD Healthline Coral Calcium?
Absorption: A key constituent of coral calcium is
readily absorbable and bioavailable calcium. A controlled
study conducted at Higashi Sapporo Hospital, Japan suggests
that calcium of coral origin is better absorbed from the
intestine than calcium of calcium carbonate origin on the
average. The enhanced absorbability of coral calcium may
be due to the fact that the coral from the Ryukyu Islands
of Okinawa contains calcium and magnesium in a content ratio
of about 2 to 1. (Ishitani K, Itakura E, Goto S, Esashi T.
Calcium absorption from the ingestion of coral-derived calcium
by humans. J Nutr Sci Vitaminol (Tokyo); 45(5): 509-17, Oct
1999).
Magnesium in Coral Calcium: Magnesium plays a role
in enhancing calcium regulation and uptake. MD Healthline
Corral Calcium contains a ratio of calcium to magnesium of
2:1. Magnesium is involved in the synthesis of protein, and
is an important co-factor in more than 300 enzymatic reactions
in the human body, many of which contribute to the production
of energy, and cardiovascular functions. While calcium affects
muscle contractions, magnesium balances that effect and relaxes
muscles. Research has shown that patients who suffer with
hypertension, asthma, coronary artery disease, leg cramps,
migraines, diabetes, cardiac arrhythmias, depression, and
multiple sclerosis have low intracellular magnesium levels
and symptoms of magnesium deficiency. Some of this is due
to the disease itself and some of it do to the medications
that the person has to take to control the actual disease.
Some good natural sources of magnesium include: whole grains;
dark-green leafy vegetables; milk and dairy products; nuts;
meat and fish; dried cooked beans, especially soy beans.
(Wardlaw , Gorden M and Kessel, Margaret. Perspectives in
Nutrition, Fifth Edition, l, McGraw Hill, Boston, pp. 419-454
and Pizzorno, Joseph E. and Murray, Michael T. Textbook of
Natural Medicine, Second Edition Churchill Livingstone, Edinburgh,
1454-1459, 1999).
Trace Minerals: The minerals and elements in the
ocean accumulate in coral calcium over thousands of years.
Most importantly, coral calcium has major and minor trace
minerals in naturally occurring proportions, similar to the
human body's mineral content. Maintaining the proper balance
of minerals in the body is critical to optimal health. There
is a significant body of scientific evidence that minerals,
in proper balance to one another, have important biochemical
and nutritional functions. The benefits of supplementing
with trace minerals may be more important than ever in light
of numerous horticultural and botanical studies confirming
the mineral depletion of soil. (Schauss, Alexander PhD, Minerals
and Human health: The Rationale for Optimal and Balanced
Trace Element Levels. Life Sciences Press, 1995).
Okinawan coral calcium contains 72 trace minerals, which
are minerals that occur in tiny amounts or traces. They play
a major role in health, since even minute portions can powerfully
affect health. They are essential in the assimilation and
utilization of vitamins and other nutrients, and aid in digestion
and provide the catalyst for many hormones, enzymes and essential
body functions and reactions. Trace minerals also aid in
replacing electrolytes lost through heavy perspiration or
extended diarrhea, and protect against toxic reaction and
heavy metal poisoning. What makes them essential is their
variable oxidation state. They are important parts of oxidative-reduction
enzymes in the body. In addition to the major minerals, calcium
and magnesium, Okinawan coral calcium includes, Aluminum,
Antimony, Barium, Boron, Bismuth, Bromine, Cadmium, Cobalt,
Chromium, Cesium, Copper, Deuterium, Dysprosium, Erbium,
Europium, Gadolinium, Gallium, Germanium, Gadolinium, Gallium,
Germanium, Gold, Holmium, Indium, Iodine, Iridium, Iron,
Hafnium, Lanthanum, Lithium, Lutetium, Manganese, Molybdenum,
Niobium, Nickel Osmium, Palladium, Phosphorus, Platinum,
Potassium, Praseodymium, Rhenium, Ruthenium, Rubidium, Samarium,
Scandium, Selenium, Silver, Strontium, Sulfur, Tantalum,
Tellurium, Tin, Tungsten, Vanadium, Yttrium, Zinc, And Zirconium.
Please note that lead contamination is not a health issue
in MD Healthline Coral Calcium, as there is there is less
than one part per million, far below US Pharmacopoeia standards.
A Full Spectrum Support Nutrient System: To make calcium
work well, other vitamins and minerals are needed to maximize
absorption. MD Healthline Coral Calcium is formulated to
make it effective even if you are deficient in one or more
of the support nutrients required for calcium absorption.
In addition to naturally occurring Magnesium, we have added
other essential nutrients, including Vitamins A, C, D and
E along with Copper, Manganese, Molybdenum,Selenium, Vanadium,
Boron, and Zinc. Studies show that these vitamins and minerals
work synergistically to allow the body to efficiently utilize
calcium.
The exact mechanism that makes coral calcium a health-promoting
supplement is not yet known. Clearly, more scientific studies
are required. Coral Calcium appears to work by means other
than just the content of calcium alone. (Halstead, B. Fossil
Stony Coral Minerals and Their Nutritional Application. Canon
Beach, OR: Health Digest Publishing Co., 1999). There is
a lot media hype that claims coral calcium is the cure for
all ailments. Such claims are absurd and preposterous. There
are many issues regarding coral calcium that remain unresolved,
and more studies are indicated. The benefits of coral calcium
reported by thousands of people must be taken into consideration.
It is abundantly clear that coral calcium is a natural mineral
supplement that contains health-promoting micronutrients,
and it is a valuable dietary supplement that is here to stay.
Recommended Dosage: Coral Calcium is best taken
two to three times a day, instead of in one dose, because
your body can absorb only 600 milligrams of elemental calcium
at a time. Best time to take coral calcium is after meals
and before bedtime. Do not take coral calcium with iron,
because it interferes with its absorption. Avoid taking coral
calcium supplements with high-fiber meals or bulk laxatives,
as they can cut down on the amount of calcium you absorb.
Over 2,000 milligrams a day of elemental calcium may pose
problems for your kidneys.
Contraindications: If you have had kidney stones
or have a family history of them, talk to your doctor before
taking any type of calcium supplements. Calcium supplementation
may decrease the absorption of tetracycline antibiotics,
iron and aspirin or salicylates, if taken at the same time
(it is recommended that dosage be separated by at least 2
hours). Calcium may decrease efficacy of thyroid hormones,
may decrease absorption of biphosphonates and some quinolone
antibiotics. Calcium benefit ceases when supplements stop.
It is now conventional to recommend that young people, especially,
have a high calcium diet to maximize bone strength and avoid
the later ravages of bone loss and osteoporosis. New studies
find that the benefit of high calcium intake only remains
while the level of intake is maintained. A three-year study
of 300 men and women over 65 years, utilizing a calcium supplement
regimen produced increased bone density, but within a year
of stopping there was no residual gain. Clearly calcium enrichment
must be a lifelong process, not just a few years of popping
pills. (Dawson-Hughes, B. et al. Effect of calcium and vitamin
d supplementation on bone density in men and women 65 years
of age or older. N. ENGL. J. MED. 337 (10) 670-6, 1997; Dawson-Hughes
B (Tufts), and Abrams S (Houston Child Nutrition Research
Center): papers at FASEB 2000).
