Calcium Carbonate is a dietetic supplement used to fulfill the calcium deficiency in the body. The body needs calcium for healthy bones, muscles, nervous system, and heart. Calcium carbonate is also used as an antacid to reduce heartburn, stomach upset and acid indigestion. It is obtainable with or without a doctor’s prescription. Calcium carbonate comes as a chewable tablet, swallowing tablet, capsule, and liquid form. It is generally taken three or four times in a day. Chewable calcium carbonate tablets must be chewed properly before being swallowed; never swallow them whole. Drink a full glass of water with either the normal or chewable tablets or even capsules. Liquid forms of calcium carbonate should be shaken well before use. Do not use calcium carbonate as an antacid for more than two weeks except if your doctor advices.

Calcium Citrate is a food additive, the number given is E 333, mostly used as a preservative, but also as a flavour giving ingredient. It is the calcium salt of citric acid, whereby calcium comprises twenty one per cent of the compound. The taste is sour as well as salty, therefore it can be used in a multitude of ways. It is commonly prescribed as a dietary supplement with patients who have received a gastric bypass surgery, but also to treat calcium deficiency and osteoporosis. Calcium citrate, next to calcium carbonate, has been recommended to people who are active in sports, especially in body building, as a bone health supplement. Increasing your muscle mass without improving the strength of your bones can lead to problems and possible injuries.

Calcium Phosphate is from the family of minerals containing calcium ions (Ca2+) together with orthophosphates (PO43-), metaphosphates or pyrophosphates (P2O74-) and occasionally hydrogen or hydroxide ions. It is increasingly insoluble at increasing temperatures unlike other chemicals so it precipitates at higher temperatures. Commercially Calcium phosphate is used in production of phosphoric acid and fertilizers. It is also used as nutritional supplement for bone and tooth health. Another practical use of Calcium phosphate is in dental products for demineralization and as diluents in some medicine. It is also used in technologies involving transfection of cells.

Coral Calcium is composed primarily of calcium carbonate (CaCO3) obtained from fossilized coral reefs. Living reefs are endangered so it is harvested from limestone deposits which were once part coral reefs. It is a source of calcium which is an essential nutrient for humans. Manufacturers claim many health benefits of coral calcium supplements, it is also claimed to be an alternative treatment for cancer however these claims are biologically unproven. In United States, Food and Drug Administration has announced them to be "Fake Cancer 'Cure'.

Iodine, a necessary element used by the body to make the thyroid hormones thyroxine and triiodothyronine. These Thyroid hormones are needed to maintain a healthy metabolic rate and cellular metabolism.

Iron is one of the most commonly available chemical elements which are used in the form of metal. When in the presence of oxygen and moisture, iron gets oxidized very easily. Therefore it is never available on the surface of earth. Iron is a metal whose properties can be changed by mixing it with the various other metals. Humans need iron as a daily dietary substance. There are a number of supplements available in market which provides the daily required dose of iron. But the best way to consume iron is by eating the food that is rich in iron. Fish, poultry, beans, lentils, leafy vegetables are some of food items that are a good source of iron. Although, research shows that it is easier to digest the iron found in meat and meat products than the vegetables.

Magnesium, which is a mineral used by the body to help maintain muscles, bones, and nerves. Magnesium is also needed for energy metabolism and protein synthesis.

Vitamin D is actually a group of prohormones, all fat soluble, whereby ergocalciferol, or Vitamin D2 and cholecalciferol, also known as Vitamin D3 are the most common forms. The Vitamin D3 form is made when human skin is exposed to UV B radiation. The active form of Vitamin D is calcitrol and it is required in the body to manage phosphorus and calcium levels, but, among other functions, to affect anti tumor activity, immunomodulatory functions and much more. Vitamin D, or more accurately calcitrol, is being bound to a carrier protein, which allows it to be transported throughout the body to the various destinations. The Vitamin D receptors, steroid and thyroid hormone receptors, can be found in most organs, including the brain, skin, heart, breast, prostate and gonads.

Zinc, a mineral needed for cell division and repair as well as proper functioning of the immune system. Zinc is also an important antioxidant that neutralizes free radicals in the body.
