B Complex Vitamins, What are they for?

Vitamin B is associated with child development processes, physical exercise and neurological activity, to name a few. However, it is much more than that. The B-complex vitamins are useful for many things, although they all look alike in some ways. Vitamin B functions are extremely broad.

Benefits and functions of group B

In general, we can find seven benefit groups and functions of Group B. Let’s look at them.

Helps the correct functioning of the energy metabolism

Vitamin B12 is responsible for this. Its job is to help convert carbohydrates into glucose, which is the energy the body uses to carry out the different functions that require a certain degree of intensity.

In addition, this is also in charge of intervening in the signalling performed by neurotransmitters, thus helping to carry out a correct and positive muscle contraction.

Improve mood

Three of the B-complex vitamins – B6, B9 (or folic acid) and B12 – are essential in the synthesis of serotonim and other mood-regulating neurotransmitters.

B12, if it works with folate, is able to produce SAM – or S-adenosylmethionine – an essential component for neurological function. It helps you cope with stress, depression and anxiety.

It has to be said, of course, that Group B by itself does not serve to treat disorders of this type, but they are considered co-factors capable of improving the performance of some other substances.

Prevent cardiovascular disease

Vitamin B6 facilitates the conversion of methionine into cysteine. Vitamin B12, on the other hand, causes homocysteine to be recycled, converted back into methionine.

Homocysteine is an amino acid synthesized from cysteine and methionine. High levels of homocysteine in the blood are associated with pathologies such as arteriosclerosis or blood clots.

Methionine-containing foods, which contain the most protein, are those that will achieve that high homocysteine level. However, we must remember that both vitamin B6 and B12 – although especially vitamin 1 – are necessary for the conversion that we have mentioned, that is, without them, however high the consumption of methionine amino acids may be, they will not achieve their purpose.

But that’s no longer all; poor treatment of homocysteine by our body can lead to heart attacks, coronary risks, blockage of the arteries and other cardiovascular system-related complications.

It will only be the stabilization of the levels of these amino acids from the consumption of B6, B12 and B9 that will achieve the correct cardiovascular functioning as well as the prevention of some related diseases.

Improve mental acuity

Again, the B6, B9 and B12 trio prevent cognitive impairment. This is given with many factors that can be controlled, however, age is one that we cannot remedy. Over the years, problems develop at the brain level that lead to dementia, mental illness, cognitive disability or lack of memory.

Returning to the previous point, we have to say that hyperhomocysteinaemia, i. e. the high level of homocysteine in the blood, can become toxic to the brain.

Strengthens bones

Of all the elements needed to maintain bone density, vitamin B12 is especially important. It acts on the formation of the matrix of connective fibers of bone tissue; it also synthesizes red blood cells.

The loss of bone density due to lack of vitamin B12 makes bones unable to regenerate, weakens and ends up leading to a process of osteoporosis.

They support vision

The B-complex vitamins reduce chronic inflammation and, as we have already said, prevent excessively high levels of homocysteine in the blood. The two problems are related to some vascular problems affecting the retina. In addition, these nutrients reduce the risk of macular degeneration and help prevent uveitis, a pathology that can lead to blindness.

They manufacture keratin

Keratin is a protein chain that protects the cells by a layer of hardness and flexibility. This essentially serves to maintain moisture and forms part of the skin, dental enamel, nails and hair.

It is vitamins B3, B6 and B12 that increase the production of keratin in both quantity and quality, making these elements more and better protected. In addition, these synthesize, as we have mentioned, the red blood cells, thus improving the transport of nutrients and oxygen.

The effects are a smooth, wrinkle-free skin, hair with natural, shiny and strong hair loss, nails that are also strong and dry, both with constant growth, and a tooth enamel of healthy color, shine and texture.

List of B Complex vitamins

B Complex Vitamins, What are they for?

The B Complex vitamins are B1, B2, B3, B5, B6, B7, B9 and B12. As is well known, these are tremendously important for our organism, considered vital. They are the ones that offer the benefits we have just discussed, along with some others that we will indicate below.

  • The CoR is 2.4 mcg.

Other B-complex vitamins and nutrients

Vegetable Foods and B Complex Vitamin

There are other nutrients of type B that form part of the group. Although they are not considered vital, they are not considered vitamins. We are talking about nutrients that were once considered vitamins and now not vitamins and nutrients. These are often indicated as B-complex vitamins but are not.

Infographics of the Vitamin B Complex benefits for health

It is evident that the B Complex of vitamins has an enormous usefulness. These are useful for many things, but as can be seen, they are particularly important in relation to red blood cells, mitochondrial activity, the structuring of DNA and RNA, the maintenance of the nervous system and the promotion of carviovascular health.

Given the importance of these B-complex vitamins, it is common to find them separately or several of them in vitamin supplements; sometimes also with vitamins of another complex. In fact, folic acid and biotin are almost obligatory in any supplement for pregnant women.

Knowing what the B Complex vitamins are for is essential. However, as important as this is knowing which ones act alone, which need to be combined with other vitamins or compounds, the recommended dosage (let’s remember how bad it is to go wrong) and, of course, know how to design a balanced diet that provides you with just what you need.
