Independent Calcium Lab Test

Lab Comparison of Calcium and Coral Calcium Supplements

What is the best form of calcium to consume? Supplemental calcium tablets sold in the stores are not always a pure form of calcium. Most have calcium components combined with stabilizers. First, these tablets must be dissolved by digestive secretions (HCl), and then ionized in order to be effective. Only a small part of the original compound actually gets dissolved, ionized, and ultimately absorbed by the body. So we had tests performed to determine, at scientific levels, what were the best forms of calcium supplements for the human body.

The following tests of over-the-counter calcium based supplements most often recommended by physicians and pharmacists were conducted by an independent laboratory.

Comparison Procedures

The tests were designed to measure the pH, the oxidation-reduction capabilities, the electrical conductivity, and the ability to counteract the Rouleauing (aggregating) effect on erythrocytes (commonly called red blood cells). The results of each product were compared to those of Alka-Line Coral CalciumT

Products Compared

The products tested were; (1) OscalT, containing biological oyster shell calcium; (2) NaturalT, containing biological oyster shell calcium; (3) Bone Meal, composed of ground and powdered animal bone; (4) AdvaCalT, containing biological oyster shell calcium; (5) CalcetT, composed of equal parts of calcium carbonate, calcium lactate, and calcium gluconate; (6) CitracalT, composed of calcium citrate; (7) MylantaT, containing calcium carbonate; (8) RolaidsT, containing calcium carbonate; (9) MaaloxT containing calcium carbonate; (10) TumsT, containing calcium carbonate; (11) Source Natural Coral CalciumT, (12) Coral Complex 2T, (13) CoraladvantageT, and (14) Ancient WisdomT, (15) Alka-Line Coral CalciumT, (16) Alka-Line Coral Calcium Capsules containing biological, ionic calcium.

Comparison Methods and Results

The tests were conducted using steam-distilled water containing crushed powders of each of the products. The pH results were obtained using standardized digital pH meters. High pH test numbers equate to a high level of alkalinity. Low pH results equate to a high level of acidity. The pH scale advances at an exponential power of 10 for each level. Alka-Line Coral Calcium registered 500 times more alkaline than the next closest product.

Oxygen-reduction results were obtained using a standard Oxygen Reduction Potential meter (ORP). The degree of negativity of an ORP reading is an indicator of how bioavailable and bioabsorbable a product will be. The more negative the test reading, the more ions are available for body metabolic functions and for the destruction of free radicals. Alka-Line Coral Calcium was the only product to register strong minus readings on the ORP meter.

Electrical conductivity measurements were tested in ohms using an OHM meter. An ohm is a unit of electrical measurement which demonstrates the amount of electrical resistance of a substance. The lower the ohm reading, the easier it is for electrical impulses to be conducted through the tissues and fluids of the body. The less electrical resistance there is the more efficiently the metabolic process progresses. This relates to ionic polarization, the osmotic gradient, and the availability of positive and negative ions within the cell membranes.

A typical ohm reading for human tissue is approximately 500 ohms. After drinking water containing 1 gram (gm) of Alka-Line Coral Calcium the ohm measurement of human test subjects dropped from 500 ohms to 40 ohms. When 1 gm of the other sample products was added to water and then consumed, there was not an appreciable difference in the ohm reading of test subjects.

Live blood cell screening, using a phase contrast, Darkfield microscope, visually shows the level of acidity present in blood serum. High acidity results in high erythrocyte Rouleau (the sticking together of red blood cells and corresponding low oxygen carrying ability). High alkalinity creates low erythrocyte Rouleau (erythrocytes are single, not sticking together, and results in the blood having a high oxygen carrying ability). The blood serum of all tests subjects initially showed no Rouleau as viewed through the Darkfield microscope. Therefore, the blood serum of all test subjects was alkaline in nature at the onset. A cola was then given to the test subjects to acidify their blood serum.

Product samples were randomly given to the test subjects to see if the sample would restore the subject's blood serum to the "no Rouleau", alkaline condition. Identical comparison tests were conducted over a five-day period. The higher the pH reading advances in alkalinity, the less amount of erythrocyte Rouleau present. Alka-Line Coral Calcium was the only product that returned the blood serum of the test subjects from a highly acidic, high blood Rouleau condition to a highly alkaline, no blood Rouleau condition.

Product Correlation

There was a high correlation between the pH level of the sample products and the amount of erythrocyte Rouleau. There was less correlation between the ORP readings and electrical conductivity between the products. However, the Alka-Line Coral Calcium did register the lowest electrical resistance (ohm) score and only the Coral Calcium products gave readings on the negative side of the ORP meter. However, Alka-Line Coral Calcium was the only product that showed positive biological function results in all four of the test areas.

Comments

The wide range of variability displayed by the testing results seems to be linked with the bioavailability and bioabsorbability of the type of calcium being ingested. Calcium minerals, in their elemental state, are normally only 8 to 40% biologically available to animals and humans. After reaching the age of 35 to 40, the availability of minerals to humans drops to 3 to 5%. Older people may not produce enough digestive acid to put calcium, magnesium, and potassium into ionic suspension. When you use the non-biologically active forms you put these people at risk as the minerals will neutralize the stomach acid and damage the digestive process. This makes the ionic form the only logical choice for the older people, and really the only logical choice for anyone who wants to be healthy.

It is important to look at not only the absorption of minerals, but also the actual mineral element content. Calcium lactate is an example of a typical calcium supplement. But calcium lactate isn't calcium. It's calcium and lactate. A 1,000 mg tablet of calcium lactate will chemically break down to 860 mg of milk sugar or lactose and 140 mg (or 14%) of elemental calcium. So it is mostly lactate. The 140 mg of elemental calcium from the calcium lactate must them undergo digestion in order to become ionized calcium. The end result is that only 10% of the original elemental calcium ingested is ionized and becomes bioavailable to the human body. This means that after the 140 mg of elemental calcium from calcium lactate completes the digestive process you will end up with 10% of the original 140 mg, or 14 mg of biological ionic calcium available for metabolic use. Different types of calcium provide different percentages of elemental calcium. For example, calcium carbonate provides 40% elemental calcium with only 10% of that ionized, while calcium gluconate supplies 9% elemental calcium with only 10% of that ionized.

It is important for calcium to be consumed in healthy amounts. Although, just because it is consumed it does not always end up being fully absorbed by the body. Usually, between 10 to 40% of dietary elemental calcium intake is absorbed. However, women after menopause may only absorb 7%. Calcium from milk and milk products is absorbed at a higher percentage rate (45%) than calcium from supplements because of the co-factors found in the milk. However, the high fat and pesticides and bovine growth hormones in the milk make it less than desirable to consume in large amounts. All dietary calcium must be made soluble (ionized) in the stomach and then pass to the small intestine where it combines with a calcium binding molecule so it can be absorbed (chelated). Because calcium competes with zinc, manganese, magnesium, copper, and iron for absorption in the intestine, a high intake of one mineral can reduce the absorption of others. The end result is that although calcium is the most important mineral to the body, it is often the hardest of all the minerals to absorb.

Alka-Line Coral Calcium is an ionic, biological form derived from pure Sango coral. It is already in the ionic form, therefore it is 100% bioavailable and does not have to undergo the digestive, ionizing process to which the other calcium and some coral calcium supplements must be subjected. This makes it superior to all other forms.

This testing was done to clear up the disputes involving calcium products, and especially different brands of coral calcium at a scientific level. We have been involved with coral calcium for many years and we know the results. We didn't need the proof. Needless to say, the scientific evidence is most gratifying, proving what we have known for years.
