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.

Iron is a necessary mineral for humans, needed for example to help form red blood cells which transport oxygen around the body. Fortunately there are plenty of good sources available for both the omnivore and the vegetarian or vegan These include liver, meat, beans, nuts, dried fruit , also whole grains and many of dark green leafy vegetables, although some such as spinach also contain substances that prevent the absorption of iron as do caffeine based drinks such as tea and coffee. On the other hand the drinking of fluids containing vitamin C aids the body in its necessary task of absorbing iron.

Vitamin A is the second Vitamin that was discovered, after Vitamin B. It can be found in several forms, whereby the primary source is the natural retinol derived from animal food sources. Chemically related compounds are called retinoids and are used primarily in medicine and as dietary supplements beta-carotenes. While carotene forms stemming from dietary sources are not toxic, intake of synthetic and natural retinoid forms should be strictly limited. Vitamin A is found naturally in beef, pork, chicken, turkey and fish livers; in the sweet potato, carrot, broccoli leaf, butter, spinach, pumpkin, eggs, papaya, mango, peas, winter squash, apricot, cantaloupe melon and leafy vegetables. Vitamin A is necessary for normal reproductive capabilities, membranes, tissues, skin, eyes, normal tooth and bone development and much more.

Vitamin C- Perhaps the most popular vitamin, L-ascorbic acid is viewed as an essential nutrient and is required to synthesize collagen in humans. The L-enantiomer of ascorbic acid, or Vitamin C for short, is the famous ingredient of oranges and other citrus fruits. It has been said that a glass of pure squeezed orange juice provides the daily requirement of Vitamin C. While the antioxidant function is deemed important, other biosynthetic functions are of vital significance. It provides an electron for eight different enzymes, besides the aforementioned synthesis of collagen; it aids the synthesis of carnitine and neurotransmitters, synthesis and catabolism of tyrosine and the metabolism of microsome. The additional function as a reducing agent, keeping iron and copper at bay is an additional trait.
