what are the uses of vitamin b complex (B1, B2, B3, B5, B6, B8, B9 and B12) details information

A large number of different nutrients, vitamins, and minerals are required for the human body to carry out its daily work and for us to feel good about it.

Although large quantities of vitamins are not essential, their importance for health is indisputable. In addition to a balanced diet, one way to provide the body with the vitamins it needs is vitamin complexes. it is a preparation that contains vitamins,

it is normally used when a lack of vitamins is anticipated, and this may be due to improper nutrition or for any reason (overwhelm, playing sports) that increases the body’s needs.

Vitamin complexes contain minerals, nutrients, and vitamins in the form of capsules or pills. These are designed so that, with just one daily dose (generally), you can increase or add these substances additionally to your diet, since they are vital for your health.

These help with the prevention of diseases, and complications related to age or some diseases, promote good bone, joint, and muscle health, etc. reduce fatigue, and increase energy,

help with hair and nail growth, provide a boost to your day-to-day life, and improve your memory and concentration, among many other benefits for your body. 

Correct doses:- follow the instructions in the letter regarding the doses you should take of the said vitamin. An excess can harm your health. Also look at the way you should consume it,

Because depending on the product it can vary, there are some that are soft capsules, chewable, syrups, and powder to mix with water or another drink.

Vitamin B1 | thiamin


Thiamine is necessary to obtain energy (ATP) through carbohydrates. For this reason, it is very important in the practice of endurance sports such as cycling, long-distance running, etc., since the higher the consumption of carbohydrates, the greater its requirement.

It is also involved in the functioning of the nervous system and the heart.


It is found in a large number of foods, but generally in small amounts. Its main vegetable sources are cereals, nuts, yeast, and legumes. It is also found in foods of animal origin such as liver and pork.

Deficiency:- Its deficit can cause alterations of the nervous system such as Beriberi and it must be borne in mind that its absorption is limited by alcohol consumption and the presence of thiaminases, responsible for the degradation of this vitamin. These are found in raw fish, coffee, and tea among other foods.

Vitamin B2 | Riboflavin

In most foods, vitamin B2 is in the form of a coenzyme and is released when it reaches the stomach by the action of certain enzymes.

This vitamin is stored in coenzyme-forming tissues such as the heart, liver, and kidneys, and is eliminated through urine, sweat, bile, and breast milk.


One of its most important functions is as a coenzyme in processes related to energy production, such as the beta-oxidation of fatty acids.

In addition, it is important in maintaining the health of tissues such as those of the eyes and skin.

It is also necessary for the proper function of vitamins B3 and B6, which we will see below.


Riboflavin is abundant in milk and eggs, being responsible for the yellowish color of whey and egg white.

It is also found in other foods of animal origin such as organ meats and fish. In the plant kingdom, it is found mainly in legumes and green vegetables.


Its deficiency causes skin problems, such as seborrheic dermatitis, and eye problems, such as itchy eyes or seborrheic accumulation around them, among others.

Vitamin B3 | Niacin


Niacin is part of the coenzymes NAD and NADP, which participate in many oxidation-reduction reactions, being essential in the metabolism of carbohydrates, proteins, and fats. Hence its relevance in the practice of sports.

In addition, NAD is involved in such important functions as DNA repair.

It is also involved in the production of sex hormones and hormones related to stress.


Although most of this vitamin is obtained through food, a small amount of it can be synthesized in the liver from the amino acid tryptophan.

We can find it widely distributed among foods. Emphasizing its presence in the viscera, fish, legumes, and meat.

For its part, tryptophan is abundant in milk, meat, and eggs.


Its deficiency produces pellagra, a disease that causes skin, digestive and nervous problems.

Vitamin B5 | Pantothenic Acid


Vitamin B5 is essential in the metabolism of fats, carbohydrates, and proteins. Specifically, it is part of ACP (Acyl Carrier Protein), essential in lipogenesis, and Coenzyme A, necessary for the metabolism of carbohydrates, fatty acids, and some amino acids.

In addition, it participates in the formation of some hormones and helps in the regeneration of tissues.

Its importance in the practice of sports lies in its fundamental role in energy metabolism, its support for the synthesis of steroid hormones, and its participation in general health.


(Meat. Fish)

Pantothenic acid is found in virtually all foods, hence its name (“pantos” meaning everywhere).

It is especially abundant in meats, cereals, and legumes, being found in smaller quantities in fruits and vegetables.


Its deficit is very exceptional, due to its abundance of food. This can cause gastrointestinal, neurological, and muscle cramps among other symptoms.

Vitamin B6 | pyridoxine

Functions: This vitamin acts as a coenzyme in the metabolism of amino acids, so an increase in protein consumption in the diet leads to an increase in its needs.

In addition, it facilitates the release of liver and muscle glycogen.

It is also involved in the formation of red blood cells and is essential in the regulation of the nervous system.


Vitamin B6 is widely found in food. It should be noted its high content in meats such as chicken, fish such as salmon, nuts, legumes such as lentils, and whole grains.


Supplementation may be necessary in case of very high protein intakes, before treatment with oral contraceptives or penicillin, and certain pathologies.

Its deficit can cause growth retardation, skin disorders, depression, and seizures among others.

Vitamin B8 | Biotin

What are the uses of vitamin b complex In food, biotin is generally bound to proteins and once these are hydrolyzed, it is released and absorbed by the body.


Like the other vitamins mentioned, biotin participates in the breakdown of carbohydrates and fats for energy. In addition, it participates as a coenzyme in the formation of fatty acids.

It is often called “the beauty vitamin” since it contributes to the health of skin, hair, and nails. It also intervenes in the health of the circulatory system and is a stimulator in the growth of healthy cells.

On the other hand, it helps the proper functioning of vitamins B5, B9, B12, and amino acids.


Biotin is widely found in foods but in very small amounts.

Good sources of these vitamins are liver, nuts, yeast, and egg yolk, among others, although it must be borne in mind that egg white contains avidin, a substance that prevents the absorption of biotin, but which is inactive with heat. 


It is difficult for its deficiency to occur due to its abundance in food, however, it can occur due to the high intake of raw eggs. The consequences of its deficit are among others: digestive alterations, alopecia, hypotonia, and metabolic acidosis.

Vitamin B9 | Folic Acid

(*Formula: C19H19N7O6 *Metabolism: Liver *Soluble in: Water)

Main used:- (Pregnancy) OB | Gyn, blood amount.

This vitamin is well known by pregnant women since 1931, folate was identified as a nutrient required to prevent anemia during pregnancy and today it is administered to women before becoming pregnant to prevent deformities in the placenta, birth defects of the brain, and spina bifida.

Unlike other water-soluble vitamins, folic acid is stored in the liver, so its daily consumption is not essential.

The disease of lack of vitamin B9

It is quite common to have low levels of folic acid. Alcoholism, inflammatory bowel disease (IBD), and celiac disease can all cause folic acid deficiency. Also, certain medications can lower folic acid levels in the body. Folic acid deficiency can cause:

*poor growth*tongue swelling
*Gingivitis*loss of appetite
*Difficulty breathing*diarrhea
*mental laziness

Pregnant women need more folic acid to reduce the risk of neural tube birth defects, including cleft palate, spina bifida, and brain damage.

Neural tube defects are birth defects caused by abnormal development of the neural tube, a structure that ultimately gives rise to the brain and spinal cord.

Since folic acid has been added to many grain foods in the United States, such as bread and cereal, neural tube defects have decreased dramatically.

Birth defects

*pregnant women who don’t get enough folic acid are more likely to have children with birth defects. Pregnant (GYN) women should take 600 mcg of folic acid daily.

Women planning to become pregnant should be sure to take the recommended 400 mcg per day since many neural tube defects can occur soon after conception and before a woman knows she is pregnant.

Prenatal vitamins contain the necessary amount of folic acid for pregnant women.

*Studies show that women who take folic acid supplements before conception and during the first trimester can reduce their risk of having children with neural tube defects by 72-100 %.

Other studies suggest that in the context of grain fortification with folic acid, folic acid supplementation does not appear to offer additional benefits in preventing spina bifida.

*Child promotion studies show that taking prenatal folic acid medicine at the time of conception is connected with a lower risk of autism.

Other studies show that taking folic acid supplements in early pregnancy was associated with a lower risk of severe language delay in children at the age of 3 years.

And some research suggests that low folate levels during pregnancy are associated with an increased risk of emotional problems in offspring.

*Folic acid may also help prevent miscarriage, although the evidence is unclear.

Available For children

Vitamin B9 is found in multivitamins, including children’s chewable and liquid drops and B vitamins. It is also sold separately.

It’s a good idea to take folic acid as part of, or along with, a multivitamin because other B vitamins are needed for it to work. It vita b available in a variety of forms, including soft gels, tablets & lozenges.

*The importance of folic acid before pregnancy

It is essential to educate the future mother so that she does not have problems at the beginning of the pregnancy.

How? Through an early prenatal consultation that offers nutritional advice and information on folate supplements, iodine, and other vitamins & minerals before pregnancy.

In addition, you must avoid tobacco, alcohol, and drugs at all costs, as well as drugs that are not supervised by a doctor.

*Lastly, I want to underline the importance of taking folic acid, iodine, group B and D vitamins, and some minerals such as zinc a few weeks before pregnancy.

All these components not only help increase the fertility of the woman who wants to get pregnant but also prevents the development of neural tube defects (NTD) such as spina bifida, heart and kidney malformations, and promote the correct intellectual development of the baby.

*Folate levels are generally very low in Spanish women despite the large number of vegetables we consume. Folic acid(derived from vitamin B9) at a dose of 400µg facilitates the formation of DNA and is one of the synthetic folates that is most prescribed in states of demand such as pregnancy. By promoting proper cell growth, they have been observed to prevent the onset of neural tube defects, premature births, placental abruption, restricted intrauterine growth, recurrent miscarriages, preeclampsia, and intrauterine deaths.

*Many women who want to start pregnancy are unaware of these relevant data and do not even consider starting their consumption three to four months before. Natural floats are not enough, since when vegetables are cooked, more than 70 percent deteriorate. Hence the need for folate supplements before becoming pregnant, throughout pregnancy, and in the puerperium. This folate enhances its action if it binds to vitamin B12.

what are the uses of vitamin b complex baby brain development

The Iodine, except for thyroid disease in which case the endocrinologist will indicate it, must be supplemented through iodized salt or administered orally. Almost all preconception nutritional supplements on the market, as well as during pregnancy, contain folic acid, iodine, and vitamin B12 together.

Iodine is essential to produce thyroid hormones and it is known that brain development needs these hormones from the sixth week of gestation.

If a pregnant woman reaches these first weeks without adequate concentrations of thyroid hormone, her baby’s brain will not develop properly and her child will probably not be at the top of the class.

Hence the importance of taking iodine several weeks before trying to get pregnant.


*It is necessary for the formation of red blood cells, so it prevents anemia.

*It also participates in the formation of structural proteins and hemoglobin.

*It helps maintain the health of the intestinal tract, preventing colon and rectal carcinoma, and intervenes in the metabolism of homocysteine, reducing its concentration and preventing cardiovascular diseases.

*Age-related hearing loss:- One study suggests that vitamin B9 supplementation helps slow the progression of age-related hearing loss in older people with high homocysteine ​​levels and low folate in their diet. It is not known whether healthy elderly people would benefit.

*Cancer information

Folic acid in the diet appears to protect against the development of some forms of cancer such as-

*Cervical cancer *Colon cancer *breast cancer *Pancreatic cancer *Stomach cancer.

This evidence is based on population studies that show that people who get enough folate in their diet have lower rates of these cancers. Researchers don’t know exactly how folate might help prevent cancer. 

Low dietary folate intake may increase the risk of developing breast cancer, particularly in women who drink alcohol. Regular alcohol consumption, more than 1½ to 2 glasses per day, is associated with an increased risk of breast cancer. One large study, involving more than 50,000 women followed over time, suggests that adequate folate intake may reduce the risk of alcohol-associated breast cancer.

Main Sources:

Folates are usually found in abundance in green leafy vegetables such as spinach. They also abound in green asparagus, peas, citrus, yeast, whole grains, salmon, and liver among others.

More food and dietary Sources

Rich sources of folate include:

*beets*Spinach *Asparagus *dark green leaves *Brussels sprouts

*turnips *Mustard leaves *lima beans *beer yeas *soy *calf liver

*root vegetables *wheat germ *whole grains *bulgur wheat *White beans *beans and beans *lima beans *Salmon

*mung beans *Orange juice *Milk *Avocado

Additionally, all grains and cereal products in the United States are fortified with vitamin B9.

Deficiency summary:-

*Its deficiency manifests itself with diarrhea, loss of appetite, weakness, headache, tachycardia, irritability, and other symptoms.

*Problems in the newborn such as low birth weight, premature delivery, and spina bifida can occur in pregnant women with folate deficiency. 

Vitamin B12 | Cobalamin

Vitamin B12 is involved in numerous processes necessary for maintaining good health.

Benefits of vitamin B12:

*Helps reduce fatigue.

*It is essential for the functioning of the cells of the body, especially those of the bone marrow, the nervous system, and the gastrointestinal tract.

*It contributes to the maturation of red blood cells in the bone marrow.

*It also participates as a coenzyme in numerous processes related to tissue growth and regeneration.

Main Sources: Vitamin B12 is produced only by microorganisms. Therefore, the main source of obtaining B12 through food is through the consumption of foods of animal origin such as meat, organ meats, eggs, and fish and we can also find it in lesser amounts in milk. Vegetables lack it.

These patients may develop symptoms of irritability, mania, dementia, depression, states of psychosis, etc.

It has been suggested that psychosis may be a presenting symptom, manifesting as mistrust, both visual and auditory hallucinations, and delusions of persecution.

Genitourinary disorders such as incontinence and erectile dysfunction may also be present. Some cases will have pictures of hypotension due to sudden changes in position (orthostatic hypotension).

How long to recover from vitamin b12 deficiency 

When the administration and/or absorption of vitamins is deficient, hypovitaminosis appears and with it, diseases.

Vitamin B 12 deficiency is associated with neurological deficits, precisely due to the importance of this vitamin in the central nervous system.

The nervous system needs vitamin B 12 because its function is to intervene in the synthesis of myelin, a layer that covers the body of neurons and is involved in the transmission of nerve impulses.

Vitamin B12 deficiency causes discontinuous, diffuse, and progressive demyelination at the level of the spinal cord (dorsal and lateral cords), peripheral nerves, and the cerebral cortex.
