There are many vitamins that we take daily in all types of food. Of course, there are some more important than others and each one has its own functions. Among all that it brings us, this time we will see what are the best benefits of vitamin B12 for hair.

Benefits of Vitamin B12 for hair loss

Cobalamin is one of the most important micronutrients for hair health. Although most people know only and exclusively the advantages of biotin or B8, another of the B-complex vitamins, for hair health, the truth is that the benefits in the first one’s hair are very many.

It should be noted that vitamin B12 nourishes all cells of the body, including hair follicles. Therefore, having it at the right levels guarantees good hair growth, not only in quantity but also in quality; hair grows healthier and stronger.

It also plays a leading role in the formation of red blood cells, which carry oxygen through the blood. This is why it is a very important nutrient to strengthen the hair follicles and that these are properly oxygenated. Thus, blood pumps and comes full of life to the cradle of our hair.

Low levels of vitamin B12 are a relatively serious disease that has both short-term and long-term adverse health consequences. In relation to hair, the lack of this nutrient translates into premature hair loss and/or very slow hair growth. Similarly, the strength of this one will not be at all similar to that of a healthy, nutrient-laden mane.

It should also be noted that melanin is responsible for pigmentation and color of hair and skin. If we do not have good levels of B12 in sufficient quantities, melanin levels will decrease. Thus, there may be signs of aging of the hair, such as hair loss or graying, before time. Of course, the shine disappears.

Thus, a mane fed by B12 will be able to have a remarkable shine, with a rich color and according to the age of the person, will grow quickly and populously and will be very strong, showing healthy from root to tip.

Other health benefits of vitamin B12

As we have already mentioned, B12 is essential in the production of red blood cells. Since they are in charge of carrying oxygen to the blood, they are indirectly responsible for the whole body to function well, because that oxygenated blood is what nourishes the cells and makes them work; this happens not only in the hair but at all levels. Any cellular function, from providing shine to regenerating our hair tissue, requires a supply of oxygen at the cellular level.

It also plays a very important role in the production of neurotransmitters, such as dopamine and serotonin, so that it can improve the symptoms of people with depression.

On the other hand, we have to say that cobalamin is essential for myelin, the material that covers the nerves of the body and helps the electrical impulses between the different nerve cells in the body to transmit better. Thus, our nervous system and its important functions depend on this vitamin.

Vitamin B12 has many other benefits such as energy production, tissue generation and regeneration or mental exercise.

Foods rich in vitamin B12 are of animal origin. There are some foods of plant origin that contain it, but in very low quantities, far removed from the daily necessary contribution. Therefore, people who do not include animal foods in their diet, such as vegan or vegetarian people, should take supplements (see below). It will also be the case of people with some type of digestive problem that does not allow a good absorption of this micronutrient.

The foods of animal origin richest in cobalamin are the following. On the one hand, beef and veal; beef tenderloin contributes no less than 13 micrograms per 100 grams of product. Pork liver and other animals and chicken breast are good choices too. On the other hand, eggs, with a contribution of 1.3 micrograms per 100 grams of product.

And finally, among fish, salmon, herring, sardine and tuna are the ones with the highest vitamin B12 content. There are many other foods rich in B12, these are just a few examples. As for food of vegetable origin, the tempeh or fermented soybean and some mushrooms stand out. However, the amount of this nutrient does not reach, by any means, that of food of animal origin.


A wide variety of cyanocobalamin supplements are available on the market in terms of format and presentation. The most common thing between vegans and vegetarians is to take a pill or tablet once a week, which has a nutrient intake of between 1000 and 2000 micrograms. No prescription required.

People who suffer from a digestive problem that prevents them from absorbing the vitamin correctly will require prior consultation with their doctor to determine causes and solutions. In any case, supplementation will require direct contact with the bloodstream, without the need for absorption; injections or nasal gels are the options but, in this case, they do need a prescription.

Suitable products

There are many different types of hair, so it is important to take care of them with specific products for them.

The vast majority of us use the blow dryer to dry our hair after washing. Well, it is important to bear in mind that heat affects hair health very negatively, weakening the scalp and making hair look more fragile and dry and brittle. Ideally, you should opt for masks or serums that act as a protective barrier against heat.

In the case of brushing or using a plate or tong, the protection must be maximum and always betting on quality products.

Cold Water
