Vitamin B12, a chemical compound known as cobalamin or cyanocobalamin because of its cobalt content, is one of the vitamins in the B group. B12 is an essential micronutrient for our body and its main function is to help and maintain healthy neurons and blood cells. Another very important function of B12 is to manufacture the DNA of our cells, it also has the ability to prevent a type of anemia known as megaloblastic anemia that appears when we lack vitamin B12. The main symptoms when we lack it are weakness and general tiredness. It is important to know that this is a water-soluble vitamin, i. e. it dissolves with water, so the risk of suffering from some type of excess vitamin B12 disease is lower.

What is the B12 vitamin or cobalamin?

Vitamin B12 exists in several forms:

Vitamin B12 has other names by which we can call it cobalamin or cyanocobalamin, although it is also known as the “energetic vitamin” since one of its main functions is to produce energy through the transformation of fatty acids, also collaborates in the production of blood, regulation and synthesis of DNA and manufacture of myelin.

B12 is available only naturally in foods of animal origin, this is one of the main reasons and causes that people who practice a vegan or vegetarian diet may have deficiency of this vitamin, which does not mean that people who do not perform this type of diet may have vitamin B12 deficiencies and vice versa.

One of its main characteristics is its solubility in water, although it has a different aspect from other types of vitamins because B12 is not instantaneously eliminated by urine but its “useful life” in our body is much longer. It is stored in the kidneys, our liver and other body tissues.

History of vitamin B12

Despite its vital importance for the proper functioning of the human body, vitamin B12 was the last vitamin to be discovered. It was not until 1842 that he began his research with the English physician Thomas Addison. The doctor began to observe an increasing number of patients with symptoms such as weakness or yellowish skin for no apparent reason. Well, in 1860, Austin Flint, a New York doctor, linked these symptoms to gastric disease. It was in 1872 that a doctor first approached the real problem; Bierner associated these symptoms with pernicious anemia.

Thanks to Bierner’s contributions to medicine in relation to cobalamin deficiency, in 1925, two Boston doctors, George Minot and William Murphy, developed the first theory for the treatment of this pathology. Such was their discovery that they won the Nobel Prize.

The next advance in the history of lack of vitamin B12 was made by William Bosworth Castle at Boston City Hospital in the 1920s. The doctor analyzed several patients and found that their anaemia was due to a lack of an intrinsic factor, which was key to the absorption of the extrinsic factor. Years later it was discovered that the intrinsic factor in question was a glycoprotein that was produced in the walls of the stomach and that upon contact with the extrinsic factor, vitamin B12, allowed its absorption.

In 1972, Robert Burns Woodward, an American chemist and Albert Eschenmoser, a Swiss chemist, managed to find the definitive cure for pernicious anaemia. Vitamin B12 plays a key role in people’s quality of life. It helps considerably to reduce tiredness and fatigue, as well as to ensure a good psychological condition and vital functions in our body.

Since its functions are many and the symptoms of its lack and excess, very varied, it was very difficult to find out what happened to patients who had pathologies derived from a problem with cobalamin, as very often erroneous diagnoses were made and often not to be heard again about the subject.

What is vitamin B12 for?

This micronutrient helps us to preserve our brain and nervous system in perfect conditions, as it keeps the myelin sheath of nerve cells in shape and also participates in the synthesis of neurotransmitters of neurons, in addition, is a preventive agent of anemia such as megaloblastic anemia, avoiding the typical symptoms of fatigue and weakness in humans.

Vitamin B12 is also used for the production of the DNA that makes up our cells, the creation of red blood cells and some proteins, and also influences the metabolism of certain amino acids, fats and carbohydrates.

If you follow a vegan or vegetarian diet it is mandatory to take a supplement of vitamin B12 that completes the doses of this micronutrient so important for your health.

How does our body absorb vitamin B12?

The absorption mechanism of this vitamin in group B requires 2 steps:

  • Firstly, in the stomach, hydrochloric acid is responsible for “extracting” B12 from the proteins in the food that contains this vitamin.
  • Second, the stomach produces a protein called “intrinsic factor” that is combined with vitamin B12, this process makes this vitamin can be absorbed efficiently by our body.

Certain people suffer from pernicious anemia, this type of anemia prevents the production of the protein “intrinsic factor“, because they lack this ability, they have problems to assimilate vitamin B12 in a correct way, either through natural foods or through supplements, therefore they may have deficiency of this vitamin.

A peculiarity of vitamin B12 is the ability to quickly and effectively absorb all types of alcohols, which is why B12 treatment in the form of injectables is known to counteract the effects of ethyl intoxications.

Types of B complex vitamins

Infographics of the Vitamin B Complex benefits for health

Vitamin B12 is one of the eight vitamins that form part of the B-vitamin complex (water-soluble vitamins), together with B1, B2, B3, B5, B6, B8 and B9. All of them, as well as the rest of nutrients of this type, have a purpose in nature as well as for us. Let’s see what vitamin B12 is for and other interesting information about this nutrient.

Firstly, vitamin B12 contains cobalt, the only one in the group with a metal. This is absolutely essential for the body to function properly and improve health considerably. For this reason, this vitamin is also called cobalamin.

Cobalamin in turn has a variant, methylcobalamin. While the former is the most widely used form, having cyanide group in its composition, the latter contains methyl group and is gaining popularity recently thanks to its benefits and ease of assimilation.

What are the health benefits of B12?

Like all nutrients, vitamin B12 is tremendously important to our body; in fact, it is the most complex vitamin. Its functions, benefits and properties are numerous.

  • Producing red blood cells: The main function of vitamin B12 is the production of red blood cells. More specifically, this nutrient is involved in the process by helping to synthesize them. It is essential that this function is performed correctly because red blood cells are responsible for carrying oxygen to the blood.
  • Adjusting homocysteine levels: Homocysteine is essential to prevent heart problems as well as stroke. Vitamin B12 intake, in conjunction with B9 and folic acid, allows adjustment of homocysteine levels to reduce the risk factor for these two complications.
  • Balance the nervous system: The nervous system is powerful yet fragile. It can withstand a lot but its deterioration is practically irreparable. Cobalamin ensures nervous balance, which is essential for organs such as the brain or heart and the nervous system itself to perform its functions properly. It also maintains the myelin layer, which is part of nerve cells, in perfect condition.
  • Prevent and treat the possible alterations in menstruation.
  • Keeping cells in perfect condition: The nutrient B12 will help to make nucleic acid. This is essential for cells to be maintained in good condition. It also promotes DNA and RNA synthesis and produces more and better energy, which results in improved creation of genetic material; an essential benefit for fetuses to develop optimally.
  • Synthesizing creatine: Vitamin B12 is involved in the process of synthesizing creatine, which is an essential protein responsible for maintaining the level of muscle mass. This helps the muscles to regenerate properly and maintains our body’s energy reserves.
  • Metabolize food: It is the most important vitamin in achieving it.
    Convert hydrates into glucose: Glucose is the form of energy that the body needs, so it is necessary for hydrates to be transformed in order to have it at times of physical intensity, thus avoiding feeling fatigue.
  • Creating a sense of well-being: When combined with folic acid and vitamin B6, vitamin B12 will enhance well-being and improve mood and mood by properly synthesizing serotonin and other neurotransmitters.

As you can see, there is an extensive catalogue of benefits and functions of vitamin B12, so it is clear that its lack will have a strong and negative impact on the body.

How does vitamin B12 work in the human body?

Vitamin B12 works in a very complex way in our organism. There are many factors that determine its correct assimilation, from the types of vitamin to its correct excretion, storage, absorption, transport and interference with medications.

Enzyme storage

Vitamin B12 is mainly stored in the liver, but also in other places such as the kidneys, bone marrow, pancreas, brain, testicles and even blood. However, these warehouses do not last forever and if it is not used 3 to 5 years later, it disappears. Therefore, it is necessary to ingest this nutrient regularly, ensuring that our body maintains adequate levels at all times.

The storage of this vitamin is one of the most durable, with other vitamins being far more fleeting. It is therefore easy to understand that the process of absorption of this substance is much more complex and delicate. Vitamin B12 deficiency is not a real concern in the first world because its presence in abundant types of foods to which we all have access and its storage capacity in a healthy organism makes it difficult not to ingest and assimilate the minimum amount recommended for its functions to be carried out normally.

As we say, the liver is the main organ that acts as a reservoir of this nutrient. Poor assimilation and, with it, a deficiency of B12 taken regularly may mean that it is damaged. When there is no more storage capacity, the vitamin is excreted, as discussed below.

Types of vitamin B12 and its effect on the body

If we go back to the beginning of this article, we will remember that there are two types of vitamin B12, cobalamin (or cyanocobalamin) and methylcobalamin. If we ingest the first one, the organism works to convert it into the second one. However, in this process cyanide is released, which is a toxic by-product for us and so is quickly excreted.

Corrine molecules (which are the rings of cobalt in the vitamin) are synthesized by bacteria. Afterwards, the human body, with a few exceptions, transforms them into an active form of B12 by removing the enzyme from certain prosthetic groups and replacing it with that of other groups.

Absorption

The first step to achieve a correct assimilation is chewing, which should result in a homogenization of B12 and protein R. Fatty acid is responsible for releasing the vitamin from each particle of food we eat. Therefore, it is logical to think that antacids and diseases and other pathologies that prevent the creation of stomach acids have a direct impact on the absorption of the B12 enzyme, preventing it from being carried out correctly.

The peptidases of the stomach and small intestine, which are enzymes that break certain bonds by means of water molecules, release vitamin B12 with respect to their binding to proteins. It reattached to the R protein to prevent its own degradation in the acidic environment of the stomach. The process is repeated to bind the vitamin to the protein synthesized intrinsic factor.

It is in the duodenum that the R protein is finally digested and vitamin B12 is released, binding, as we have mentioned, to the intrinsic factor, thus forming the B12+FI complex. Only in this way does the ileum recognize the complex and assimilate it. In turn, intrinsic factor manages to protect the vitamin of intestinal bacteria and their catabolism action, which is the transformation of complex molecules into simple molecules.

Transport

With the recognized complex, transport reaches the liver support system and then passes to transcobalamin II.

If there are hereditary defects related to the production of transcobalamines and/or their receptors, it is more than likely that a functional deficiency of the vitamin will occur, producing what is known as infantile megaloblastic anemia.

A further step towards making the vitamin useful is that it binds to a cell receptor, thus producing endocytosis, a process by which cells allow the introduction of large molecules or even other cells to form a gallbladder that breaks off and is incorporated into the cytosol, liquid inside cells.

A lysosome then degrades transcobalamin II by releasing B12, which is released into the cytoplasm. This is where it is transformed into the most suitable coenzyme according to the action of cellular enzymes.

Excretion

When the body stores the maximum B12 enzyme that can support excreta. This is done through bile, although much of the cobolamine that goes into this, is recycled through entero-hepatic circulation. If there is too much vitamin B12 that goes beyond the binding in the blood, it is excreted with urine without any difficulty.

B12 interference with drugs

Finally, it should be noted that B12 interacts with drugs. This is important because we may be suffering from a decline in the vitamin we ingest because it is incompatible with any medications we take.

Chloramphenicol, proton pump inhibitors, histamine H2 receptor antagonists or metaformin are drug compounds that can create vitamin deficiency as they interfere with the body’s correct treatment of B12.

For this reason it is really important to consult a doctor before starting any supplement, no matter how simple or beneficial it may seem.

Types of foods rich in vitamin B12

Vitamin B12 sources of animal origin

✅ Molluscs and crustaceans:

If you need to make up for a vitamin B12 deficiency, the intake of some mollusks is one of the fastest options. And that’s because every gram of clams has a microgram of cobalamin. Right behind, but also with very generous amounts of the nutrient we have oysters and mussels.

The octopus, on the other hand, has 0.2 micrograms per gram, but it is completed with large doses of selenium and iron, making it an ideal dish in any diet. The crab is low in calories and contains chromium, which regulates blood glucose, making it ideal as a staple food for diabetics and hypoglycemic people.

✅ Fishes:

Before moving on to the food “from the land” let us pay attention to the blue fish, highlighting the salmon, whose contribution by a portion cooked is about 10 micrograms. It is followed by sardines and tuna.

  • Vitamin B12 is also found in large quantities in certain species of fish, a very good alternative especially for older people as it is a food of easy digestion.
  • Sardines are a very healthy food, with a large amount of Omega 3 and also rich in vitamin B12.
  • Tuna is one of the richest fish in this nutrient; it contains 2.4 micrograms of vitamin B12 per 85 grams, that is, with this portion we already take the cobalamin we need for the whole day.
  • Other fish equally recommended for inclusion in diets rich in B12 are salmon, herring, mackerel and cod.

✅ Meat:

  • Beef or veal is one of the richest animal foods in this vitamin B group. It also contains very little fat, making it very healthy. Lean cuts and beef tenderloin stand out.
  • Pork liver is a delight if we talk about cobalamin, with 30 micrograms per 100 grams of pork liver pâté if it is in optimal condition.
  • Other meats rich in this vitamin group B are cooked chicken breast and lamb kidneys, which provide 39 and 55 micrograms of vitamin B12 per 100 grams.
  • A beef sirloin of about 200 grams will give us 26 micrograms of cobalamin.

✅ Eggs:

In the case of eggs, it is in the yolk where vitamin B12 is concentrated; 1.28 micrograms of vitamin B12 per egg (large). Eggs are a food with a lot of preparation possibilities and can easily be included in any diet of food of animal origin.

✅ Milk and dairy products:

  • Cheeses, in general, are very rich in cobalamin. The richest are the emmental cheese, with 3 micrograms per 100 grams of cheese, camembert, with 2.8, gouda and brie with 1.7 and goat cheese or ball cheese with 1.5 micrograms.
  • But if cheese isn’t your thing, know that low-fat yogurt and whole milk are also rich in this nutrient so a breakfast or snack that includes them will be as good a choice as any other.
  • The amount of vitamin B12 per cup of skimmed milk is 1.1 micrograms. In addition, milk is a food with a high calcium content and very nutritious.

Vitamin B12 sources of vegetable origin

For vegans and vegetarians, there are also plant-based foods rich in vitamin B12. However, the amounts of this nutrient in them are very small and in no case provide the recommended daily amount.

Some of the vegetable foods containing B12 are:

  • The tempeh
  • Mushrooms such as the trumpet of death, chantarella or shiitake
  • Algae such as candy, nori or slake and soybean

If you follow a vegan or vegetarian diet it is mandatory to take a supplement of vitamin B12 that completes the doses of this micronutrient so important for your health.

Other font types

On the other hand, we find that there are certain foods that usually have vitamin B12 additives, such as many breakfast cereals. There are known brands and also other economic ones that are typical of any supermarket. The contribution in this nutrient differs a lot from each other so the best idea is always to check the nutrition label to choose the most balanced ones and, if that is what you are looking for, with a greater contribution of B12.

It is clear that by following a balanced diet that includes all food groups we can get plenty of the recommended daily amounts of this vitamin. However, we must bear in mind that the way we cook each food influences the amount of vitamins and minerals that we finally ingest, as some of them are lost along the way. The same happens with animal breeding; depending on their physical conditions, the medicines used, etc. are lost nutrients of all kinds so these amounts indicated will never be pure.

Finally, we cannot fail to point out that, as you can see, vegan diets are completely lacking in the highly prized vitamin B12, so B12 supplements are an indispensable supplement for those who practice this lifestyle.

Types of vitamin B12 supplements in different presentations

Vitamin B12 is offered in virtually any multivitamin complex. However, it can also be taken in isolation, through different presentations such as:

Label nutritional value vitamin B12 supplement

  • Injections
  • Pills
  • Liquid form
  • Sublingual 
  • Gels
  • Spray
  • Capsules
  • Blisters
  • Drops
  • Tablets
  • Chewable
We will pause to examine what the differences are in the first two cases: injected vitamin B12 vs vitamin B12 in tablets.

Vitamin B12 injections

Vitamin B12 injections can only be obtained by prescription. This means that even if you are aware of a lack of this nutrient, it should be the doctor who corroborates it and prescribes the injectable.

This vitamin is injected directly into the muscle, which allows it to be used in the body’s basic functions without depending on other factors that limit its absorption.

Due to its immediate effectiveness and its integration in the organism, it is not used as a preventive measure or with slightly lower than normal levels, but when there really is a lack of vitamin that makes our organism does not work as it should, that is to say, when it is having a negative impact on us.

Vitamin B12 tablets

Vitamin B12 tablets are freely dispensed and marketed in varying proportions of the nutrient. You can buy B12 at a pharmacy or go to a specialist food supplement store. You’ll find cobalamin pills in various proportions, with or without other B vitamins or even other B group vitamins. The intake is made on a regular basis, with one or more tablets daily depending on its composition and sometimes even weekly if the amount of pure B12 enzyme is very high.

It is very important to know this amount per pill in order to establish an appropriate dose according to the needs of each person, which does not have to coincide with the recommended dose for another subject. For this reason, and as we have already indicated above, the best option is to always go to our family doctor so that, based on a complete analysis, he or she can tell us what daily or weekly amount is the most advisable in each case, as well as the number of doses most advisable, although we reiterate that in this case it is not mandatory but advisable.

This is a method that achieves better results than medium- and long-term injections, which is why they are less suitable to make up for a serious deficiency but better to prevent and treat minor deficiencies. Indicate that alcohol absorbs part of the B complex vitamins so that if you are a regular drinker, the tablets will cause less effect. The same is true for vitamin C supplements, which can reduce assimilation.

If you follow a vegan or vegetarian diet it is mandatory to take a supplement of vitamin B12 that completes the doses of this micronutrient so important for your health.

Vitamin B12 is one of the most important nutrients in the body. In addition to taking the recommended daily allowance, it is important to follow a healthy lifestyle. That is, to eat a healthy and balanced diet, free of high calorie foods and high in fat.

In addition, exercise is recommended between 3 or 4 times a week; it is enough to walk between 30 minutes and 1 hour, or to swim. Low intensity exercises are extremely beneficial to health and do not take up too much time or exhaust.

In case we don’t take enough, either by following diets that exclude it, by eating an inadequate diet, because our body is not able to work it properly to use it in its functions or simply if you think it is simpler, don’t doubt it; the easiest, most comfortable and safest thing is to take supplements that maintain a good level of B12 sufficient for it to carry out all its functions correctly.

F.A.Q: Frequently Asked Questions about B12

P

What is vitamin B12 for?

R

This micronutrient must be taken daily because it is essential for the body. Although we create reserves that take time to disappear, on average between 2 and 3 years, it is important to constantly replenish so that our body can use it whenever necessary. There are two simple ways to take vitamin B12.

The first is to include in our diet foods that contain it such as beef, certain parts of the chicken, a great variety of fish, strong cheeses, low-fat yogurt, eggs etc. It should be pointed out that the food of plant origin does not satisfy the demand for cobalamin of our organism.

On the other hand, we have supplements, which are taken daily or weekly. They are the solution for those who do not eat food of animal origin, for those who follow a slimming diet, for those who do not absorb the vitamin because they suffer from some pathology that prevents it and, in general, for all people who want to make sure they have adequate levels of B12. The most comfortable and usual format is in tablets or tablets, although there are sublingual, injections, drops, sprays… Each presentation is designed for a particular type of person and case.

P

How much should I take of B12 per day in mcg?

R

The recommended daily allowance is usually 2.4 mcg or micrograms for adults. The contribution obviously differs with age:

  • Infants younger than 6 months only need 0.4 mcg
  • Those with 7 to 12 months need 0.5 mcg
  • Children up to 3 years old should take 0.9 mcg
  • Between 4 and 8 years of age, 1.2 mcg is required
  • Until we were 13 years old we climbed to 1.8 mcg
  • People from 14 years of age and older are now considered that the organism has the same needs as an adult, having to take 2.4 mcg
  • Pregnant women will take a little more, 2.6 mcg
  • Those breastfeeding, 2.8 mcg

In addition, those people who have to resort to supplements will have to take considerably more for the body to assimilate and restore levels and amounts.

P

Which is better? Cyanocobalamin or Methylcobalamin?

R

Cyanocobalamin is one of the ways that B12 is found in food. Methylcobalamin is the result of the transformation of cyanocobalamin in our body. The first is found in many foods, so it is the most common to eat. As for the supplements, there are with both compositions.

In general, cyanocobalamin is recommended because it presents positive results totally effective and is much cheaper. This form is the most common and is recommended for anyone who does not have any health problems that prevent the transformation of the micronutrient. Vegetarians and vegetarians, people on low-calorie or unbalanced diets, convalescent people…

For its part, methylcobalamin is the best option, and unique in practically all cases, for those people who have difficulty in transforming cyanocobalamin, because with methylcobalamin the process is already done. It is ideal for people who are celiac or have, for example, kidney disease.

P

Which foods are richer in vitamin B12?

R
  • The food that will provide us with the cobalamin we need are of animal origin.
  • Of the meats, the liver of almost all animals, veal and clean chicken breast stands out.
  • As for fish, salmon, tuna, herring and sardines are ideal, along with caviar and other eggs.
  • The richest molluscs in B12 are clams, mussels and oysters, as well as octopus.
  • As far as derivatives are concerned, all of them offer a good contribution. Eggs, strong and cured cheeses and yoghurts and skimmed milk, the most.
  • To say that plant foods do not have this micronutrient and the very few that have something is insufficient to meet our body’s demand.
P

What are the risks of having too much vitamin B12 in your blood?

R

Although having more cobalamin on the books isn’t as serious as having less, the truth is that it also has its negative consequences. Problems in the skin or cardiovascular system can occur, with mild to moderate severity.

However, having an excess of vitamin B12 in itself can be serious. If we have more than one account because we have consumed it, we simply stop taking it. But if that’s not the case, you’re very likely to have some pathology that will cause those cobalamin levels to rise. So, it’s no longer so important what makes cobalamin at high levels but why you have that excess.

Chronic myeloid leukemia, kidney disease, or liver disease are some of the causes of this increase. We will have to go to a doctor for an accurate diagnosis and appropriate treatment.

P

What effects does the lack of vitamin B12 have on health?

R

Although the effects are very varied, they can be classified into these groups:

  • Neurological symptoms: They are very varied and range from numbness to neuroparies.
  • Confusion, lack of memory, and other mental processes that are out of tune, favouring Alzheimer’s.
  • Reinforcement of dysthymia or depression, greater apathy, bad mood…
  • Lack of energy, exaggerated tiredness or after little physical effort, fatigue.
  • Muscle weakness, tingling and others in extremities.
  • Cardiovascular pathologies such as stroke or arrhythmias.
  • Anemia.
P

How is vitamin B12 injected?

R

B12 injectables consist of two main parts: the syringe and the bottle.

  • First of all, you should take protective measures by washing your hands and putting on gloves as well as washing the area to be punctured.
  • Afterwards, you have to assemble the syringe by attaching the needle to it. You will have to place the plunger in the exact size of product you want.
  • The next step is to take the bottle of vitamin. To do this, you must open the bottle containing it and
  • clean its cap with an alcohol swab.
  • Insert the syringe, remove the air it contains, and the medicine will move to the top of the syringe.
  • Take the needle out of the syringe.
  • To administer the medication, pinch the skin of the area to be punctured and make a quick wrist movement, similar to throwing a dart, so that the needle is stuck at 90 degrees.
  • Release the skin and insert the syringe into the needle to, pressing the plunger, slowly inject the medication.
  • The needle is pulled out at the same 90-degree angle and quickly to cover the area with a cotton swab or cotton swab, and hold the cotton swab pressed down to cut off any blood spills.
P

Where can I buy good and cheap vitamin B12?

R

If you need to supplement yourself with vitamin B12, this is the right place to buy it at the best price. We only sell cobalamin presentations with the highest quality composition. We also offer a wide variety of formats and presentations so whatever you are looking for, you will find it with us.

  • Do you want a container with a lot of tablets to get cheap vitamin B12? We got him!
  • Need a B12 and folic acid supplement? Also!
  • Do you prefer it in sublingual format? In drops, flavored? Take a look at our offers because we have everything.
P

Are B12 supplements of animal origin?

R

No. These are manufactured in the laboratory from bacterial fermentation; therefore, supplemented with B12 you are not ingesting any product or compound of animal origin, that is why this type of supplements are designed and are suitable for those people who follow vegan or vegetarian diets.

P

Is it better to take supplements exclusive to B12 or with other vitamins?

R

The answer to this question is conditioned exclusively by your situation. Having trouble keeping up with the right level of all the other vitamins? If so, don’t hesitate and choose a vitamin complex or take several vitamin supplements. If you get enough of the other nutrients, it is absurd that you take them in supplement because you will excrete them or, worse still, you will suffer from excess toxicity.

It is not necessary in most cases to take another type of vitamin supplement apart from one of B12 in cyanocobalamin format. If you think you may have another deficiency, the best thing to do is to see your doctor and have a check-up and, knowing the results, you will see if you really need another extra contribution of some other vitamins.

P

If I am a ovolactovegetarian, should I take vitamin B12 supplements?

R

Although it is true that eggs and milk contain B12, if you follow a varied diet within the possibilities of this feeding style you will never get the cobalamin levels you need; for that you would have to take a huge amount of these foods and other health problems would arise.

With the amount of eggs and milk that an ovolactovegetarian takes is not enough; therefore, yes, you should supplement yourself. In this case, you can go to your doctor or nutritionist and, depending on your diet, tell you how much B12 you should take in supplements. However, this is only a good option if you follow and adhere strictly to a very specific diet. If this is not the case, it is best to take a weekly supplement of 2000 micrograms, so if, for example, you have not eaten B12 foods in a week, you should still take the necessary dose of vitamin B12 supplementation.
