Iron is vital in human nutrition as the adult human body contains 3-4 grams of iron. Haem-iron and non-haem iron are the two types of iron. Foods rich in haem-iron include meat, liver, fish, and poultry. Foods that are high in non-haem iron are those of vegetable origin, like green leafy vegetables, cereals, legumes, oilseeds, nuts, dry fruits and jiggery. Iron is vital for numerous body functions, including hemoglobin formation, brain development and function, muscle activity, regulation of body temperature and catecholamine. Deficiency of iron affects immune system, reduces the number of T-cells and production of antibodies. Iron is also necessary for binding oxygen to body cells as its main function is oxygen transport and cell respiration. It works as an anti-cancer agent. Iron increases energy level of the body, improving physical performance. It prevents insomnia.

Magnesium is the chemical element found in the periodic table with the atomic number 12. This alkaline earth metal is one of ten most common elements in the known universe and also very prominently present in the human body. It manipulates polyphosphate compounds, most prominently the DNA, RNA and the ATP. Numerous enzymes rely on magnesium ions to function properly. Most common application of magnesium in medicine may be the addition to antacids and laxatives. This metal is not found as a free element naturally on Earth, generally the metal is obtained through electrolysis of magnesium salts. The most common deficiency in the United States with staggering two thirds of the population is the magnesium deficiency. Magnesium can be obtained through vegetables, tea, cocoa, cereals, coffee, nuts and spices.

Manganese is a trace mineral that has long been associated with musculoskeletal health. It activates enzymes in the body that is necessary for the production of collagen and proteoglycan, components of connective tissue. It also aids in the absorption of calcium in the body. It helps prevent the development of osteoporosis and osteoarthritis. Manganese helps in the digestion and utilization of vitamin E in the body that makes it a potent antioxidant. It fights free radicals from damaging the cells that may lead to premature aging, heart problems and cancer. It alleviates premenstrual syndrome (PMS) such as mood swings and nausea.

Molybdenum is essential in regulating pH balance in the body, enhancing the body’s ability to burn fat. Very small amounts are needed. Molybdenum is necessary for the proper function of certain enzyme-dependent processes, including the metabolism of iron. Molybdenum also promotes normal cell function and helps in the activation of certain enzymes, it is a key component of the metabolic enzyme xanthine oxidase. Molybdenum is found in the liver, bones and kidneys. It supports bone growth and teeth strength. A deficiency may cause impotence in older men. High intakes of sulfur and diets high in refined and processed foods may decrease molybdenum levels.There is no recommended dietary allowance for molybdenum.

Niacin, also called Vitamin B3, is a water-soluble vitamin needed for the conversion of food into energy so that it may be used by the body. Niacin also helps metabolize protein, sugar and fat.

Pantothenic Acid, commonly called Vitamin B5, it is a water-soluble member of the vitamin B complex. Pantothenic acid is involved in adrenal gland function and is required to fight stress.

Riboflavin, an easily absorbed micronutrient, is also known by the name of Vitamin B2. It plays a key role in maintaining the health of animals as well as humans. A wide variety if cellular processes require this vitamin. It plays a key role in energy metabolism, just like other B vitamins. It is the kind of micronutrient which required for the metabolism of proteins, carbohydrates, fats and ketone bodies. There are a lot of food products that are a good source of Vitamin B2. Matured soybeans, yeast, mushroom, livers, kidneys, leafy vegetables, milk, cheese, almonds are such products that are rich in this vitamin. But riboflavin does get destroyed if exposed to light. Riboflavin is a non toxic vitamin. Hence, there is no harm in taking it orally.

Selenium is considered good for health if taken in small amounts. It is a trace mineral which when incorporated into protein, makes selenoproteins that helps stop cellular damage due to free radicals. The major source of selenium is plant foods and its content in the food depends on the selenium content in the soil where it was grown. Also known as selenium acid, selenium sulfide and selenium yeast, this mineral is available in seafood and meat products. The main function of selenium is to work with vitamin E in order to maintain the elasticity and preservation of tissues. It not only helps in improving the supply of oxygen and blood to the muscles in the heart but also slows down the aging process by enhancing endurance.

Vitamin C is integral to cellular metabolism as well and a lack of vitamin C can cause a myriad of issues, including scurvy.

Vitamin D- The fast soluble vitamin D is perhaps the most underrated nutrient that is produced when sunlight touches the skin. But it is extremely vital for bone health, as without it the body cannot absorb the calcium that you may provide it in the form of supplements. With the advent of beauty products with high sun protection factor, this nutrient is becoming less available to our bodies.
