How does the vitamin calculator work?

This health tool can prove to be an efficient and quick way to check how much vitamin you should have per day from the variety of elements that our bodies need.

In order to receive an adequate estimate of the daily vitamin intake you will need to provide your gender and age so the vitamin calculator can find your situation in one of the various tables being used for these recommendations.

You can also choose 5 vitamins you want to calculate at the same time to begin with but then once you know the result you can start again with other 5 vitamins that you might be interested in. You can find their names in the dropdown of the form but as well in the tables below.

Example calculation:

Let’s take for example the case of a 30 year old woman who would be interested to know how much vitamin A, B12, C, D and K her body requires on a daily basis. This is the result:

■ Vitamin A- Retinol- 700 mcg;

■ Vitamin B12- Cobalamine- 2.4 mcg;

■ Vitamin C- Ascorbic acid- 15 mcg;

■ Vitamin D- Cholecalciferol- 15 mcg;

■ Vitamin K- Phylloquinone- 90 mcg.

What are vitamins?

Vitamins are organic compounds that are essential to sustain life. These compounds have metabolic effects in small quantities. When the body cannot produce enough or none at all from an organic compound it has to take it from food, this is why vitamins are also nutrients.

If the intake is not properly adjusted to age, gender and other needs deficiency diseases can develop. There are two categories of vitamins: fat soluble vitamins and water soluble vitamins, there’s a table for each one of them with the main sources and the deficiencies that can appear.

Fat soluble vitamins are stored in the fat tissues and can be stored for long periods of time in the body:

Vitamin Sources Deficiency
A (Retinol) Chicken, tuna, milk, eggs, beef liver, potatoes, spinach, carrots, cheese, nuts and many more Keratomalacia, anemia and impaired night vision
D (Cholecalciferol) Fish and oils, eggs, fortified milk, cereals and others Rickets and osteomalacia.
E (Tocopherol) Vegetables, vegetable oils, unprocessed cereal, whole grains, nuts and fruits Hemolytic anemia
K (Phylloquinone) Green vegetables, plant oils and margarine Coagulation problems and uncontrolled bleeding

Water soluble vitamins are easier to absorb in the body but cannot form reserves as they are soon eliminated through urine:

Vitamin Sources Deficiency
C (Ascorbic Acid) Citrus fruits, tomatoes, potatoes, strawberries, cabbage, spinach and many others Megaloblastic anemia and even scurvy
B1 (Thiamine) Enriched products, whole grain products and ready to eat cereals Beri-Beri disease
B2 (Riboflavin) Meats, milk, whole bread products and fortified cereals Ariboflavinosis that comes with cracked lips, throat swelling and low red blood cell count
B3 (Niacin) Different meats, fish, poultry, whole grain breads and fortified cereals Pellagra
