Vitamin B1 is helpful in producing energy in the body, Vitamin B2 supports the other cells and works in production of red blood cells and body growth too. On addition, vitamin B3 supports in maintaining the skin and nerves fit and healthy, higher dos of it are effective in lowering the cholesterol level, even vitamin B5 is essential in metabolism process and regulates hormone and cholesterol.
Vitamin B7 plays its crucial role in metabolism of proteins and carbohydrates and thus regulates the cholesterol and hormones level too.
Folate i.e. vitamin B9 and vitamin B12 with their joint efforts supports the production of red blood cells, which is also used in making DNA and thereby controlling the cell and tissue growth and their function too. Sufficient amount of folate is significant for women who are pregnant.

Vitamin C also known as ascorbic acid, is essential in living being especially humans as it palys a major role in body’s metabolic process. Intake of vitamin C from foods and other sources should be must as it not produced by the body and is not stored for longer period by the body.
The role of vitamin C is in iron absorption, collagen formation, antioxidant, fighting against pathogens (lymphocytes need vitamin C), and also produce brain chemicals (neurotransmitters).
Only 45mg of vitamin C is required by the body on daily basis, while remaining is excreted. Raw foods is preferred the best source of vitamin C, as it is been observed that the nutritional values get reduced if the food is overcooked.

Deficiency of vitamin E may cause fat mal-adsorption such as cystic fibrosis, secondly erythrocyte hemolysis is the one of the deficiency seen in new born where vitamin E was not transferred to them prior to the birth.
Vitamin K is necessary to keep the bones intact and strong, and helpful in wound healing and blood clotting. It is also significant is new born babies to prevent serious bleeding known as hemorrhages disease of the ew born (HDN).
The best dietary source of vitamin K are the spinach, avocado, kiwi fruit, soybean oil, and kale. However, bacteria present in our body (gastrointestinal tract) are also one of the source of getting vitamin K. In case new born babies a booster dose of vitamin K is given, as they have no bacteria in their gastrointestinal tract at the time of birth
Deficiency of vitamin K can lead to the problems such as unabsorbed fat or medicines and inability to blood clotting.
Given below is the list of disease that will occur due to lack of nutrients:
|Vitamin 9 and B12
|Scurvy, Swelling of Gums
|Rickets & Osteomalacia
|Non-Clotting of Blood.
Types of minerals and their functions
Numerous minerals are been present in our atmosphere, that can be either classified as major or trace minerals . However the amount in which they are needed by the body may varies, like macrominerals are needed in higher quantity as compared to the microminerals. The list of macrominerals includes calcium, sodium, magnesium, potassium, phosphorus, chloride, Sulphur.
Microminerals or trace minerals are equivalently important in bodily functions and these includes copper, manganese, iron, zinc, selenium and iodine.
Few of the essential minerals are listed below along with their deficiencies disease and symptoms:

Vitamins are categorized as Water-Soluble vitamins which includes vitamin c, thiamin, niacin, vitamin B6, folacin, vitamin B12, biotin and pantothenic acid. Whereas the next category of vitamins are Fat-soluble vitamin which includes A, D, E, and K. The fast soluble vitamins can be absorbed and are soluble in organic solvents and are carried in the same manner likewise the fats do.
