Before you can choose the coral calcium product that is right for you you must first educate yourself on the differences.
There are three basic forms in which coral calcium products can be purchased:

1.) Sachets or "tea bags"

2.) Capsules

3.) Powdered

No matter which form you use you will not receive much of a pH benefit unless you add the product to water. This is due to the mineral oxides present in coral calcium. We will use CaO (calcium oxide) as an example. The ion responsible for raising the pH of a solution is the OH- (hydroxide) ion. OH- ions are produced when an oxide is added to water. Here is the reaction when using CaO: CaO + H20 -------> Ca++ + 2OH- . You can see that for every one CaO molecule two OH- ions are produced. If you do not mix the product with water then you will not produce the OH- ion. Drinking one glass of water with a couple of capsules won't cut it! All you will do drinking a glass of water is dilute the HCl (hydrochloric acid) in your stomach. Much of the water will be absorbed before the HCl will even have a chance to dissolve the capsule shell and release the coral calcium minerals. Once the capsule is dissolved the coral calcium powder will mix with HCl, not water, therefore the chance of producing OH- ions is greatly reduced. The ingredients needed to run the carbonic acid-bicarbonate buffer system are still provided and you can still receive some balanced pH benefits due to this, but using coral calcium treated water will give you more overall pH benefits. To achieve the best pH benefits CCP coral calcium sachets are recommended. Powders or capsules will mix carbonates as well as oxides in the water giving it a chalky appearance and flavor. Many powders and capsules also contain other vitamins, minerals, enzymes etc. that will not dissolve and will also throw off the pH values. The antioxidant power is also higher using CCP sachets. This is measured in mV and the greater the reduction or more negative a reading the more benefit that is available. Electrical conductivity, electrical tension, and surface tension are all more dramatically improved using CCP sachets than with any capsules are powders. Since only the ionic minerals are released using the sachets there is no need for vitamin D to be added. If you feel as though you do need more vitamin D in your diet to absorb other forms of calcium you could always stand in the sun for fifteen minutes or so.

The coral calcium powders and capsules are also very important. A person will consume more of the ingredients needed to run the carbonic acid-bicarbonate buffer system from coral calcium powders or capsules. Since most of the carbonates from coral calcium sachets remain in the actual "tea bag" itself you will consume more of the actual minerals from using a powder or capsule. This is when most people ask the question "Then why not just use the powder since it is mixed with water and you consume all of the minerals?" To produce a powder that will mix thoroughly in water the coral calcium must go through more processing. The more processing that any natural product goes through the less effective it becomes. All of the grinding and pulverizing causes much friction which reduces electrons etc. rendering the product less effective.

In conclusion, if you are extremely mineral deficient then you should use a coral calcium powder or capsule along with the sachets so that you can achieve the maximum benefit that coral calcium has to offer. If you are just looking for an all around great supplement to use just for maintenance of great health then the coral calcium sachets are all you need. The best coral calcium sachets, capsules, or powders to use are those that contain no other ingredients along with the coral calcium except for vitamin D. Other vitamins, minerals, enzymes etc. will only throw off the natural balance of this live giving product making it less effective. Coral calcium powders and capsules should not be taken with meals. Vitamins should be taken with meals to be properly absorbed, so why would you add vitamins to coral calcium anyway?
