Vitamin D helps in the absorption of calcium in the intestines and also its re-absorption in the kidneys. It helps in attaining and maintaining the serum levels of calcium and phosphates in the blood. This helps in the mineralization of the bones. Vitamin D promotes bone growth, bone remodeling and with out sufficient vitamin D bones may become brittle, thin and misshapen. Together with calcium it protects the elderly people from osteoporosis.
In the human body vitamin D has other roles like reduction of inflammation, neuromuscular activities and immune functions. vitamin D is believed to reduce the risk of colorectal, breast and prostate cancers.
Vitamin D deficiency may arise from inadequate consumption of its source foods, insufficient exposure to sun light and from disorders limiting its absorption in gut and its re-absorption from kidneys.
The deficiency lead to Rickets in children and softening of bones and osteoporosis in adults. Rarely deficiency may be hereditary. Rickets in children may result in stunted growth and misshapen long bones resulting in deformity.
Osteomalacia occurs in elderly people with symptoms of muscle weakness and fragile bones due vitamin D deficiency. Osteoporosis arises with loss of bone density resulting in brittle bones and fractures. Symptoms of bone pain and muscle weakness may be due to inadequate vitamin D levels. These symptoms can be subtle and go undetected in the initial stages.
Children may suffer from insufficiency if the nursing mothers are deficient in vitamin D. Moreover mother's milk may not contain sufficient vitamin D and unless the children are exposed to sun light and, or supplemented with vitamin D they may develop rickets.
Homebound people and people living in northern latitudes may suffer from the deficiency of this vitamin. Darker skin also may reduce the ability of the skin to produce vitamin D from sun light. However excessive sun exposure to avoid deficiency carry the risk of skin cancer.
Vitamin D deficiency is connected to increase in blood pressure and cardiovascular risk. In dialyses patients low levels of vitamin D can lead to diabetes, hypertension and cancer.
Exposure to extended time does not cause toxicity as the excess produced is degraded. Generally vitamin D toxicity is very rare and its symptoms are nausea, poor appetite, weakness and weight loss.
Very few foods are natural source of vitamin D. Fish liver oils, liver, cheese and egg are the best sources. For further information please visit http://www.thedynamicnature.com/vitamins/vitamin%20D.html.
Except humans most of the mammals can synthesize vitamin C in their body.
Humans, therefore have to obtain their supplies from their diet.
Vitamin C is a very essential nutrient and its deficiency may cause disease Scurvy.
Vitamin C is essential for healing of wounds. It is very important for the formation of collagen.
Collagen is an important protein and is found in the scar tissues, blood vessels, skin and ligaments.
Vitamin C is an antioxidant and stops the damage caused by free radicals.
The action of free radicals over a long time causes aging.
Vitamin C protects us from cancer, heart disease and arthritis by binding to free radicals, slowing the aging process.
It is believed that vitamin C regenerate oxidants like vitamin E.
Vitamin C is observed to reduce the symptoms of autism.
Vitamin C has been found to increase the fertility in men.
Increasing the immune function and slowing down the aging process are its other beneficial effects. Vitamin C intake also lowers the blood pressure.
Scurvy causes hair loss, tooth loss, bleeding, joint pain and swelling.
Scurvy when untreated is fatal. However with the advance in medical knowledge it can be treated completely with vitamin C supplements.
Large doses of vitamin C can cause indigestion and diarrhea.
Food sources of vitamin C:
The human body does not manufacture vitamin C and cannot store it.
So it is very important to add vitamin C in our diet daily.
The rich natural sources of this vitamin are, fruits and vegetables, liver, citrus fruits, leafy greens and green peppers.
Biotin is essential in the metabolism of fatty acids and in glucose synthesis. For cell growth, production of fatty acids and in the metabolism of the fats and amino acids biotin is necessary.
Citric acid cycle is a process by which biochemical energy is generated during aerobic respiration and biotin has very important role in it. Biotin helps in the maintenance of blood sugar levels. Biotin helping various metabolic reactions helps in transfer of carbon dioxide.
Biotin is often recommended for hair and nails care. hence, it is used in many cosmetic and health products for the hair and skin. Biotin is usually recommended to counter act the problems of hair loss. Biotin may be involved in the production and release of insulin. Type 2 diabetes patients have been found to have low levels of biotin.
Loss of hair and in severe deficiency loss of hair on the eye lashes and eye brows has been encountered in the case of biotin deficiency. Biotin deficiency is also triggered by excessive consumption of raw eggs. The raw egg white contains high levels of protein avidin which binds to biotin. However avidin is deactivated by cooking while biotin remains intact. In general appetite and growth are affected.
There are few side effects associated with higher doses of biotin. In rare cases stomach irritation and dermatitis have been reported.
Biotin is distributed in a variety of foods in low concentrations. Cereals, seeds, nuts, fruits and vegetables may be consumed to ward off any deficiency. For further information visit http://www.thedynamicnature.com/vitamins/vitamin%20B7.html.
In human beings it is can be manufactured by the intestinal flora.
This vitamin is found to be involved in the metabolism of fatty acids and amino acids.
VitaminB5 plays an important role in secretion of hormones and in the support of adrenalin gland.
Apart from the healthy maintenance of skin, muscles and nerves, these hormones help in the fight against allergies.
Pantothenic acid is used in the creation of hemoglobin, lipids and steroid hormones. It is involved in the production of energy.
There is a opinion that this vitamin is also helpful in the treatment of wrinkles and graying if hair.
Pantothenic acid is reported to be useful in the treatment of rheumatoid arthritis.
Pantothenic acid deficiency is rare and has not been thoroughly studied.
The deficiency symptoms can be reversed with sufficient intake.;Most are minor, including fatigue, allergies, nausea, and abdominal pain.
Biochemical changes include increased insulin sensitivity, lowered blood cholesterol, decreased serum potassium.
Toxicity of pantothenic acid is unlikely.
Large doses of the vitamin, when ingested, have no reported side effects and massive doses may only yield mild intestinal distress and diarrhea at worst.
Most of the foods contain Pantothenic acid.
Higher concentration are found in meat products, in whole grains, brans, fish, legumes, yeast, eggs, fresh vegetables, kidney, liver, mushrooms, nuts, saltwater fish, whole rye flour, and whole wheat flour.
Vitamin B-5 can be found in avocado, brown rice, broccoli, and dairy foods, and is also synthesized by friendly bacteria within the body.For further information visit http://www.thedynamicnature.com/vitamins/vitamin%20B5.html.
Its mild deficiency slows down the metabolism.
This results in low tolerance to cold. Severe deficiency of Niacin causes the disease pellagra.
Niacin is important for ridding the body of harmful and toxic compounds.
Niacin has effect on the hormone glands of the body and helps in their healthy condition for the normal healthy life.
In human body the amino acid tryptophan can be converted into niacin.
Niacin improves circulation and cell respiration. Apart from being a memory enhancer it helps in treatment of mental illness and schizophernia.
Corn is low in niacin and in places where corn is the staple food the deficiency of niacin is found.
Shortage of niacin shows symptoms such as loss of appetite, indigestion, diarrhea, depression, dizziness, headaches, insomnia, low blood sugar, fatigue, muscular weakness, limb pains, skin eruptions, canker sores, and inflammation.
Severe deficiency may cause pellagra, the well known niacin deficiency disease, and is characterized by bilateral dermatitis, diarrhea, and forgetfulness.
Heavy long term dosages have been found to cause liver damage though higher dosages have been found to treat a number of ailments.
Niacin has been found to lower bad cholesterol and increase good cholesterol. Niacin has been found to be effective in prevention and treatment of atherosclerosis and heart diseases.
Physician must be consulted before using high doses.
The best dietary sources of niacin are found in beetroot, yeast, liver, meat, chicken, fish, unrefined cereals except corn, fruits and vegetables.

Vitamin B2 is known as Riboflavin and is water soluble. This vitamin plays a very important role in the cellular process. It is required for energy metabolism. It is a key factor in the metabolism of fats, carbohydrates, proteins and ketone bodies.
In the release of energy from glucose and fatty acids in the mitochondria, Riboflavin is one of the constituent co enzymes. Riboflavin has an important role in the DNA syntheses and red blood cell formation. It is believed that supplement of Riboflavin helps in relieving migraine.
When taken along with food Riboflavin is absorbed in the small intestine. It is found that in empty stomach it is absorbed very poorly. When protein is lost from the body Riboflavin is also lost. Any excess of Riboflavin is excreted in the urine. Riboflavin need increases in the nursing mothers. Riboflavin is useful in prevention and treatment of cataracts and eye ailments.
Riboflavin is helpful in health of mucous membranes.
It is very beneficial to skin, hair and nails.
Deficiency of Riboflavin can be primary or secondary.
The deficiency can lead to inflammation of the mucous membrane, cracked lips and mouth corners and sore throat.
The deficiency can lead to loss of skin tenor and iron deficiency anemia.
The eyes can become bloodshot and sensitive to light.
As riboflavin is excreted easily in urine there in no observed toxicity. However if injected into blood stream in high doses toxicity may occur.
Milk, organ meats, nuts, cheese, eggs, green leafy vegetables, fish, legumes, yeast and almond are good sources of Riboflavin but exposure to light destroys Riboflavin.

The B vitamins are eight in number and are water-soluble vitamins.
They are dispersed through out the body and play important roles in cell metabolism.
Historically, the B vitamins were once referred and classified as vitamin B.
Later on research showed that they are distinct vitamins with different chemical make up but often coexist in the same foods.
Vitamin B complex benefits for skin care and skin health
:Supplements containing all eight of them are generally referred to as a vitamin B complex. Individual B vitamin supplements are referred to by the specific name of each vitamin (e.g. B1, B2, B3 etc ).
They are listed below with the details of their chemical components.
Vitamin B3 (niacin, includes nicotinic acid and nicotinamide)
Vitamin B5 (pantothenic acid)
Vitamin B6 (pyridoxine,pyridoxal, and pyridoxamine)
Vitamin B7 (biotin, also known as vitamin H)
Vitamin B9 (folic acid)
Vitamin B12 (various cobalamins; commonly cyanocobalamin in vitamin supplements)
B vitamins are essential nutrients for variety of bodily functions like growth, function, disease resistance etc... They play a major role in the enzymatic activities that regulate chemical reactions in the body, turning food into energy and other needed substances.
They promote growth by helping cell division . Supporting and increasing the rate of metabolism, toning up skin and muscle, enhancing immunity, enhancing the functioning of the nervous system and promoting the growth of Red blood cells and hence preventing anemia are the known functions of B vitamins.
B vitamins are water soluble and are to be replenished daily as in excess they are excreted in urine. Deficiency of certain B vitamins may cause anemia, tiredness, loss of appetite, abdominal pain, depression, muscle cramps, respiratory infections, hair loss, eczema, poor growth in children, and birth defects in the fetuses of pregnant women.
Women who are pregnant or breast-feeding require more folic acid as the development of brain in a child depends very much upon its availability in sufficient amounts right from conception to three years of age.
Vegetables, fruits, liver oils, liver, fish, meat, grain products and yeast. Nutritionists recommend that adults over the age of 50 take B vitamin supplements as its deficiency is common in this age group.
These vitamins make the skin firm, youthful, glossy and protect it from blemishes and diseases. The deficiency of B vitamins can give rise to a myriad of skin problems.
The deficiency of vitamin B complex causes skin diseases like dermatitis (skin inflammation with itch and pain), Cheilosis (cracking of lips and chapping of lips), Skin sensitivity, glossitis (swollen tongue), seborrheic dermatitis (dandruff), angular cheilitis (cracks on the corner of mouth), acne and pimples, white spots on the skin (due to loss of melanin pigment), hair fall and hair loss and skin cancer.

The biological activity of the organic compounds get them classified into vitamin groups.
In many cases a vitamin may denote a group of organic compounds having similar biological activity and may have different chemical structures.
The essential nutrients like carbohydrates, proteins, fatty acids and dietary minerals are not to be confused and grouped with vitamins. Vitamins function in different roles like antioxidants, enzymes, co-enzymes, hormones and catalysts. Though the requirement of vitamins and their sources in food were enlisted long back now they are being synthesized commercially. Vitamins are classified into fat soluble and water soluble vitamins.
In human beings of 13 vitamins nine are water soluble and four are fat soluble. The fat soluble vitamins (A, D, E and K ) are absorbed, stored and accumulated in the body, where as water soluble vitamins are readily absorbed and readily excreted. This property of these vitamins requires our consistent intake. The deficiency of vitamins can result in a number of maladies. The primary deficiency occurs when a person is short of vitamins in his food.
In the secondary deficiency due other external factors a person is not able to absorb utilize vitamins. Unless the core problem is resolved the secondary deficiency can lead to irreparable damages. The over dosage of vitamins can also cause problems. This is experienced when vitamins are taken in a supplementary form like tablets. This can be corrected by reducing the dosage.Visit http://www.thedynamicnature.com/vitamins/vitamins.html for more information.
