Vitamins are chemical substances that are essential for the body to carry out key chemical reactions for humans, such as the transformation of energy (carbohydrates into ATP). A lack of vitamins, as well as an excess of them, can lead to serious illnesses or complications.

In general, a healthy diet (fruits, vegetables, cereals, meat,…) is enough to acquire an adequate amount of vitamins, on the other hand, in case of illness, in certain periods of childhood (for example, in babies who need of supplements in vitamin D ,..), in convalescence or even, in the case of a bad diet, an external supplement (for example, in the form of pills available in pharmacies) is necessary.

Sometimes, the use of vitamins can also have a preventive effect, for example, the use of vitamin C or folic acid, which help to fight the flu syndrome and spina bifida, respectively.

These are the vitamins:

*Fat-soluble vitamins:

– Vitamin A

– Vitamin D

– Vitamin E

– Vitamin K

*Water-soluble vitamins:

– Folic acid

– Biotin ( vitamin H )

– Vitamin B1 ( thiamine )

Vitamin B2 ( riboflavin )

– Vitamin B3 ( niacin )

– Vitamin B5 ( pantothenic acid )

– Vitamin B6 ( pyridoxine )

– Vitamin B12 ( cobalamin )

– Vitamin C

* Explanation and definition of fat-soluble and water-soluble vitamins

– Liposoluble vitamins: Water-insoluble vitamins: vitamins that are eliminated more slowly by the body, as it is possible to store them in fat.
So beware of excess fat-soluble vitamins (vitamins A, D, E and K)!

– Water-soluble vitamins: Water-soluble vitamins: vitamins that are eliminated more quickly in the urine, as they are water-soluble.
However, as they are eliminated more quickly, it is necessary to absorb them more frequently, in food or through food supplements.

Unnecessary and dangerous vitamin supplements for women most

WASHINGTON — Vitamin supplements are useless for most people. Some of them can even lead to fatal risks in older women, according to a study published in the United States.

Iron supplements are among the most worrying, say the researchers, while those based on calcium seem to be related, on the contrary, with a decrease in the risk of mortality, according to the study published by “Archives of Internal Medicine”, a publication of the American Medical Association.

“We found that several commonly used vitamin and mineral supplements, such as multivitamin products, vitamin B6, folic acid, iron, magnesium, zinc, and copper, are linked to increased risk of death,” note the American and Finnish authors.

consumption on the rise

This study was performed using data from another study conducted in Iowa (central United States), including questionnaires completed by 33,772 women with a mean age of 62 years. There they reported the consumption of vitamin supplements in 1986, 1997 and 2004.

The proportion of those taking supplements in this sample increased from 66% in 1986 to 85% in 2004.

The study published Monday points to iron as “strongly” linked to increased mortality, depending on the absorbed dose. The authors note, however, that they were unable to determine whether the reasons these women took up iron could explain the higher mortality rate. They stress that more studies are needed.

Calcium, however, was on their side and unrelated to a decrease in mortality.

more is not better

The results “reinforce our belief that certain antioxidant supplements, such as vitamin E, vitamin A or beta-carotene, can be dangerous,” note the doctors in a commentary accompanying the study.

“The more is better paradigm is wrong,” they add, noting that they don’t recommend the preventive use of such supplements, at least, “in a well-nourished population.”

“We see little justification for the widespread use and spread of these supplements,” the study authors conclude.

About half of the US population takes vitamin supplements. They represent a $20 billion market.
