What is Vitamin?
Vitamins are the essential micronutrient that is needed for the proper functioning of metabolism. Organisms are unable to synthesize these vitamins in the body, thus you need to obtain it through diet. There are 13 recognized vitamins and they are either water-soluble or fat-soluble.
Vitamin A, D, E and K are fat-soluble and are stored in the liver and fat tissues of the body. The body can store fat-soluble vitamins more easily than the water-soluble ones. These are absorbed with the help of lipids or fats through the intestinal tract.
Deficiency of vitamin A can cause keratomalacia (an eye disorder that causes a dry cornea) and night blindness. The sources of vitamin A include liver, cod liver oil, broccoli, carrots, butter, kale, pumpkin, spinach, some cheeses, apricot, egg, milk and many more.
Vitamin D deficiency can cause osteomalacia (the bones become soft) and rickets (weak and soft bone). The main source of vitamin D is sunlight. Vitamin D is also found in eggs, fatty fish and mushrooms.
Sources of Tocopherol or Vitamin E include Kiwi, almonds, avocado, eggs, milk, nuts, green vegetables, wheat germ, and whole-grains. The deficiency of Vitamin E is uncommon, but sometimes it causes hemolytic anemia (blood cells are destroyed and removed before time) in newborns.
Vitamin K is essential for blood clotting and the Deficiency of it prevents the blood from coagulating, thus it causes excessive bleeding from normal punctures from the injection or any wounds, blood oozing from gum and nose, and easy bruising. The sources of vitamin K are green vegetables, kiwi, avocado and parsley.
There are 9 water-soluble vitamins. Vitamin B group (this includes 8 vitamins) and vitamin C. The body can not store water-soluble vitamins and they are excreted rapidly in the urine.

The sources of vitamin B2 or riboflavin include asparagus, persimmons, okra, cottage cheese, yogurt, milk and many more. The deficiency of vitamin B2 may cause ariboflavinosis (symptoms include sore mouth).
Niacin or Vitamin B3 may cause pellagra, dermatitis, diarrhea and mental disturbance. Liver, heart, kidney, chicken, beef, milk, eggs, avocados and others are the good sources of this vitamin.
The sources of vitamin B5 include whole grains, meats, broccoli, avocado, royal jelly, and fish ovaries. The deficiency of vitamin B5 causes paresthesia (an abnormal skin sensation that includes, tingling, chilling or numbness without any apparent reason).
The deficiency of vitamin B6 may cause anemia (lack of red blood cells and hemoglobin), peripheral neuropathy (damage to the nerves that carry messages to and from the brain and spinal cord). The sources of vitamin B6 include meats, bananas, whole-grains, nuts, vegetables, and milk.
The sources of vitamin B7 include egg yolk, liver, and some vegetables. The deficiency of this vitamin causes dermatitis or inflammation to the intestine.
Vitamin B9 deficiency during the time of pregnancy can cause birth defects. Leafy vegetables, liver, some fortified grain products, and sunflower seeds are some good sources of vitamin B9.
Vitamin B12 or cyanocobalamin is generally present in fish, meat, shellfish, poultry, eggs, milk, and dairy products. The deficiency causes megaloblastic anemia (where bone-marrow produces large and abnormal red blood cells).
The deficiency of Ascorbic acid or vitamin C causes scurvy. The sources of vitamin C include citric fruits and vegetables.

Side Effects of Multivitamins
While taking a multivitamin, the dosage is the most important factor. A high amount of vitamins and minerals can be seriously harmful.
The appropriate dose of multivitamins depends on solubility. For instance, for a water-soluble vitamin, the body expels excess amount. But your body has no easy way to get rid of the fat-soluble vitamins.
If you eat a lot of nutrient-dense foods and take multivitamin supplements, then you can exceed the recommended intake of many nutrients.
- Pregnant women need to be careful before taking any multivitamin containing vitamin A and Vitamin C. As an excess vitamin A intake can cause birth defects.
- Smokers should also avoid taking vitamin A and Beta carotene as these can increase the risk of lung cancer.
- A high dose of multivitamins can cause upset stomach, diarrhea or constipation. Though these effects are generally temporary and disappear when your body adjusts the multivitamin medication.
- Seek immediate medical attention if you notice any allergic reaction like rash, itching, trouble breathing or severe dizziness.
Always remember a balanced diet of fresh whole food is way more beneficial than any supplements. Multivitamins do not provide you the pass to optimal health. Do not take multivitamins to fix your poor diet.
In fact, the evidence that multivitamins can improve health is not proved. In some cases, multivitamins may cause harm. In the case of a nutrient deficiency, take a supplement for that specific nutrient.
