Ionic Coral Calcium Product Comparison Of All Your Calcium Supplements Including Coral Calcium Tea Bags

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 o the original calcium compound actually gets dissolved and ionized.
Tests of over-the-counter calcium based supplements that are most often recommended by physicians and pharmacist were conducted by an independent laboratory. Following is a comparison of not only typical forms of calcium found on the market but also an ionic coral calcium product comparison where coral calcium tea bags are also compared.   

The tests were designed to measure the pH, the oxidation-reduction capabilities, the electrical conductivity, and the ability to counteract the rouleauing effect on erythrocytes (which will vary depending on the degree of acidity within the blood serum). The results of each product were compared to those of Alka-Line Ionic Coral Calcium.

All products tested were mathematically configured so that the amount of calcium available for testing equaled 1,000 mg. When necessary the products were physically crushed until all samples had matching consistencies. After the crushing, each product was dissolved in 100 ml of steam distilled water.


The products tested were; (1) Oscal, containing biological oyster shell calcium; (2) Natural, containing biological oyster shell calcium; (3) Bone Meal, composed of ground and powdered animal bone; (4) AdvaCal, containing biological oyster shell calcium; (5) Calcet, composed of equal parts of calcium carbonate, calcium lactate, and calcium gluconate; (6) Citracal, composed of calcium citrate; (7) Mylanta, containing calcium carbonate; (8) Rolaids, containing calcium carbonate; (9) Maalox, containing calcium carbonate; (10) Tums, containing calcium carbonate, (11) Source Natural Coral Calcium, (12) Coral Complex2; (13) Coraladvantage (Product endorsed by Robert Barefoor); and (14) Alka-Line Ionic Coral CalciumTM, and Alka-Line Coral CalciumTM Capsules, containing biological, ionic calcium carbonate from Sango Coral).


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 CalciumTM registered 500 times more alkaline that 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. Alka-Line Ionic Coral CalciumTM was the only product to register minus readings on the ORP meter.

Electrical conductivity measurements are 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 normal ohm reading for human tissue is approximately 500 ohms. After drinking water containing 1 gm of Alka-Line Coral CalciumTM the ohm of a human test subject dropped form 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 creating a low oxygen carrying ability). High alkalinity creates low erythrocyte rouleau (red cells are single, not sticking together, and results in the erythrocytes having a high oxygen carrying ability). The blood serum of all test subjects initially showed no rouleau as viewed through the phase contrast, Darkfield microscope. Therefore, the blood serum of all test subjects was alkaline in nature. A cola product was 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 is present. Alka-Line Coral CalciumTM was the only product that returned to blood serum of the test subjects from a highly acidic high blood rouleau condition to a highly alkaline, no blood rouleau condition.

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 reading and electrical conductivity between the products. However, the Alka-Line Ionic Coral CalciumTM did register the lowest electrical resistance (ohm) score and only the Coral Calcium products gave reading on the negative side of the OP meter. However, Alka-Line coral CalciumTM from Sango coral as the only product that showed positive biological function results in all four of the test areas.


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 mineral, 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 product enough digestive acid to put calcium, magnesium, and potassium into ionic suspension.

Calcium lactate is an example of a typical supplement. A 2,000 mg tablet of calcium lactate will chemically break down to 860 mg of milk sugars or lactose and 140 mg (16%) of elemental calcium. The 140 mg of elemental calcium from the calcium lactate must then 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 hat after the 140 mg, or 14 mg of the 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, while calcium gluconate supplies 9% elemental calcium.

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 form milk and mild products is absorbed more easily and at a higher percentage rate (45%) than calcium form supplements. Dietary calcium must be made soluble in the stomach and then pass to the small intestine where it combines with a calcium binding molecule so it can be absorbed (chelation). Calcium competes with zinc, manganese, magnesium, copper and iron for absorption in the intestine, and a high intake of one can reduce the absorption of the others.

Alka-Line Coral CalciumTM, however, is already in ionic, biological form derived from pure Sango coral. Therefore, it is a 100% ionic, bioavailable calcium and does not have to undergo the digestive, ionizing process to which the other calcium and some coral calcium supplements must be subjected.
