Calcium, is a supple gray alkaline earth metal, which is the fifth most abundant element by mass in the Earth's crust. Calcium is also at the fifth most profuse dissolved ion in seawater by both molarities and mass. Calcium is a significant nutrient that we require in our bodies. It has many imperative functions. It helps getting strong teeth and bones and is involved in muscle contractions and blood clotting, The calcium is mainly stored in our teeth and bones. Low calcium level may lead to the bone fractures and in some cases porous bones or osteoporosis, generally in old age. The intake of calcium can drop down the high blood pressure, maintain your heart functions, avert gum disease, prevent colon and rectum cancer, and help blood to clot.

Copper is a naturally occurring mineral in foods like shell fish, vegetables, avocado fruits, legumes, grains, nuts, and beef. As copper originates from the earth's crust, the surface water and ground water contains small traces of copper. Copper is implicated in many biochemical reactions within the human cells.

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.

Potassium, a mineral that is quite common in our food. Potassium is needed for proper muscle growth, nervous system and brain function and to help balance the PH of our bodies.

Riboflavin, also called Vitamin B2, is naturally manufactured by the body. Riboflavin is needed for the proper use of oxygen and amino acids, carbohydrates and fatty acids. Riboflavin is also utilized by Vitamin B6 in the body and is used to manufacture niacin. Riboflavin is especially needed when eating large amounts of protein.

Sodium is the element that has the atomic number 11 in the periodic table and is commonly known as the main component in the table salt, together with chloride. Interestingly enough, it is probably the one dietary component which does require limitation rather than supplementation, since that average daily nutritional requirement is around half a gram per day. This most popular food seasoning, salt, is providing the most common source of sodium and chloride in human diets, but is generally overused and may cause health problems, such as high blood pressure, if consumed overly generously. The suggested dose of table salt, or rather the upper limit portion, would be somewhat less than 6 gram per day, according to the Dietary Guidelines for Americans, referenced by FDA. In the UK this limit is set at four grams per day.

Thiamine, also called Vitamin B1 or Thiamin, is needed to help the body utilize energy from proteins, fats and carbohydrates. Thiamine is commonly found in breads and cereals. Thiamine is water-soluble and is concentrated in muscle tissue as it passes thru the body.

Vitamin A is a fat-soluble vitamin with known toxicity. Although its toxicity has been exaggerated, it is a factor worth keeping in mind. Carotine is converted in the human body to Vitamin A, it comes from vegetable sources. Vitamin A is necessary for normal growth and for skeletal development.

Vitamin B12 is a water soluble vitamin and is one of the 8 B vitamins. It has the chemical formula C63H88CoN14O14P. In the absence of Vitamin B12, the brain and the nervous system will not be able to function properly. It also plays a key role in the formation of blood. Vitamin B12 was discovered from its relation to the ailment pernicious anemia. Plants and animals are not capable of synthesizing VitaminB12; the enzymes required for this purpose are found only in bacteria. Vitamin B12 deficiency in human beings is due to its complex human physiology. It is available singly or in combination with other supplements.

Vitamin B6 is one of the most important vitamins that play an essential role in the development and keeping the immune system healthy. Vitamin B6 is water soluble that contains pyridoxal, pyridoxine, and pyridoxamine. It is needed by the body in various functions such as red blood cell metabolism and conversion of the amino acid tryptophan to the vitamin niacin. It is also important in ensuring the efficient function of the nervous and immune systems. It helps manufacture proteins and neurotransmitters, haemoglobin, and prostaglandins. It also helps balance the hormones. Vitamin B6 is known to help give relief to women suffering from menopausal symptoms, and premenstrual syndromes. It also helps reduce the incidence of breast cancer.

Vitamin C- The essential nutrient L-ascorbic acid, or rather Vitamin C, is necessary for a wide plethora of metabolic reactions in almost all living beings. In humans, Vitamin C is vital in the collagen synthesis. While most beings are able to make it internally, apes and humans cannot. Interestingly enough, while widely promoted as the best dietary source of Vitamin C, Oranges are dwarfed by the Kakadu plum, which has sixty times the amount. Prominent are rose hips, blackcurrant, red peppers, parsley, the kiwifruit, broccoli, redcurrant, several berries including strawberries and raspberries, as well as more exotic fruits and vegetables like Camu Camu, acerola, seabuckthorn, Indian gooseberry, jujube, guava and baobab. Tomatoes, while very popular Vitamin C source in the US, are very low on the Vitamin C scale.

Vitamin E is the name for a group of tocopherols and tocotrienols that are soluble in fat and display antioxidant properties. The most important vitamin out of this group is alpha tocopherol, which professes the highest bioavailability, and therefore, was the most studied Vitamin E. Found in such foods as nuts, seeds, milk, wheat germ and most vegetable oils, this Vitamin is said to be perhaps the most important antioxidant in human nourishment, although this trait is not deemed the imperative reason why Vitamin E is required to be in every diet. Most clinical studies which were supposed to crown Vitamin E as the prevention from prostate cancer or cardiovascular wonder supplement have been either inconclusive or were discontinued due to poor results. Vitamin E deficiency results in neurological and neuromuscular problems, but also in failure to absorb fat.

Zinc is acknowledged as essential to the human organism. It is a trace element found in over a hundred and up to three hundred enzymes. It is the second most important mineral in the body, after iron. Zinc is also defined as an important catalytic agent, which is active in enzymatic reactions such as hydroxilation, which is essential for the protein forming amino acid proline, but also for hypoxia response. Zinc is naturally found in red meat, milk, spinach, nuts, oysters, beans and oats. Low zinc counts can attribute to a weakened immune system, interfere with muscle building, cause diarrhea and all kind of other deficiencies. In body building circles, Zinc is an important supplement, valued for the indirect increment of testosterone and the muscle building role.
