What does vitamin B12 do to your body?

DNA synthesis and the metabolisation of fats, hormones and neurotransmitters are only some of the different important processes of the human body in which the vitamin plays a part. It also participates in the creation of blood, in cell division and is a key player for the human nervous system.

This incredible vitamin regulates and cares for our immune system, so you should always maintain its levels optimal.

The role played by vitamin B12 in the immune system means that correct supplementation can help you fight symptoms of various diseases, such as:

  • Anaemia
  • Chronic fatigue
  • Diseases of the nervous system
  • Mental illnesses such as depression, dementia, and schizophrenia
  • Autoimmune diseases

What foods are rich in vitamin B12?

Vitamin B12 can only be synthesised by microorganisms; its presence in meats is the reason why we need to integrate this food into our diet. On the other hand, legumes are a plant source of vitamin B12.

However, it is important to note that vegetable sources contain much less vitamin B12 than meats. This is why experts often recommend adequate supplementation of this essential vitamin if you are a vegan or vegetarian.

How much do vitamin B12 supplements cost?

The price will always vary depending on the quality of the supplement and its brand. However, a higher dose of vitamin B12 usually means a steeper price.

The following table introduces you to prices of different cobalamin preparations:

Type Price
Sublingual tablets (30 units) Approx. AUD 5-30
Capsules (30 units) Approx. AUD 24-30
Spray or drops (100 ml) Approx. AUD 30-48
Injections (100 ml) Approx. AUD 5-80

Sublingual tablets are by far the cheapest form of vitamin B12, while injections are the most expensive. However, the latter are actually essential for pregnant women and people with severe cobalamin deficiency.

What are the symptoms of vitamin B12 deficiency?

Vitamin B12 deficiency is unfortunately very common, especially if you do not include meats in your diet. The elderly are another at-risk group, as they frequently have trouble absorbing the vitamin correctly.

The most common symptoms of a vitamin B12 deficiency are:

  • Pale or yellow skin
  • Dizziness
  • Vision problems
  • Mood swings
  • Mouth sores
  • Tiredness and fatigue

What are the consequences of vitamin B12 deficiency?

The consequences and symptoms of a vitamin B12 deficiency are closely linked. People with this condition are tired all the time because the red blood cells are not produced quickly enough to supply their body with oxygen.

Vitamin B12 is also involved in the production of myelin, a key substance for a healthy nervous system. Other long-term problems stemming from this deficit include anaemia, tiredness and dizziness, as well as conditions related to the lack of oxygen in the body.

How does a vitamin B12 deficiency occur?

Vitamin B12 deficits are a lengthy process: stored in your liver, your vitamin B12 reserves can last two to three years. A vitamin deficiency naturally occurs when all your reserves have been depleted, which is when you’ll begin to notice the first symptoms.

Here are the reasons that can lead to a cobalamin deficiency:

  • Low vitamin B12 intake
  • Problems with vitamin absorption
  • Increased need for vitamin B12

Low vitamin B12 intake is common amongst vegans, vegetarians, and people with poor nutrition.

You may difficulties reaching your recommended daily intake if you follow a vegan diet; however, certain cereals fortified with this vitamin are now available for you.

Certain people such as pregnant women or people with autoimmune diseases require higher intakes in vitamin B12. In these cases, adding vitamin supplements to the diet becomes an excellent option.

Dr. Sally P. Stabler Medical Doctor

“Gastrointestinal absorption depends on the intrinsic factor, a glycoprotein synthesised by the gastric parietal cells and in the “cubam receptor” of the distal ileum.”

Cobalamin absorption can be affected for people suffering from certain conditions. The following can be causes for a vitamin B12 deficit:

  • Gastrointestinal diseases, such as gastritis or Crohn’s disease
  • Complications to the liver
  • Alcoholism
  • Chronic smoking
  • Consumption of birth control pills

Should I use vitamin B12 supplements if I am vegan or vegetarian?

We highly recommend you to take vitamin B12 supplements if your diet is strictly vegan or vegetarian. This is because the main sources of vitamin B12 are usually foods of animal origin such as meat, fish and seafood.

Despite the fact that they can consume milk and eggs, vegetarians should also add B12 supplements to their diet, as their intake may be deficient. If you’re unsure about where you stand, we recommend that you get a blood test and check that all your blood values are under control.

foco

Did you know that cobalamin was another name for vitamin B12? Its name comes from its chemical composition, as it contains cobalt.

Can I be cobalamin-deficient if I am not vegan or vegetarian?

Yes, non-vegetarians with poor nutrition may still have vitamin B12 deficiency. Certain gastrointestinal diseases and other health problems can prevent people from absorbing cobalamin properly, so we recommend that these groups at risk check their vitamin B12 levels.

What types of vitamin B12 are there, and which one is right for me?

As mentioned earlier, there are essentially seven forms of administration available on the market:

  • Normal or sublingual tablets
  • Capsules
  • Spray and drops
  • Injections and vials

Each type has a different concentration of vitamin B12, and its own advantages and disadvantages. This is why we recommend you to know exactly your specific needs in order to choose the best form for your body.

Here are the different types of vitamin B12 and their benefits and specificities.

Sublingual tablets Capsules Spray and drops Injections and vials

Shopping Criteria

In this section, you will find the most relevant purchasing factors for choosing your vitamin B12 supplement. They are the following:

  • Effectiveness
  • Side effects
  • Price
  • Allergens
  • Active substance
  • Aroma

Effectiveness

Vials will be your best ally if you need to deal with a serious vitamin B12 deficiency. Injections are another methods indicated for severe symptoms of nutrient deficiency. Standard tablets and capsules should be efficient enough if your deficiency is not extreme.

Side effects

Certain preparations contain additives such as magnesium stearate and are therefore not recommended for sensitive people, while others may cause heartburns or headaches. We strongly suggest you study all components and side effects of a product before buying it.

Price

A product’s cost is always a deciding factor when making a purchase, but it’s not the only one. Some supplement packages may for example include a money-back guarantee in case you are not satisfied. Remember that price and quality are always closely connected.

Allergens

The most common allergens are eggs, milk, soy, gluten, peanuts and other nuts. If you are allergic to any such product, we strongly recommend you buy vegan supplements, as they are usually allergen-free.

While this is less frequent, cyanocobalamin, the active substance in vitamin B12, can also cause allergies. Present in vials and injections, it can cause very severe allergic reactions.

Active substance

Various forms of vitamin B12 are available on the Australian market. Its most common forms are the synthetic cyanocobalamin, and the natural forms: hydroxocobalamin, adenosylcobalamin and methylcobalamin.

  • Cyanocobalamin: This substance is created from a combination of vitamin B12 and cyanide. While it is easy to synthesise, this form can cause strong allergic reactions. Therefore, smokers and individuals with kidney problems should avoid this substance, as cyanide can cause complications.
  • Hydroxocobalamin: This substance is usually found in cobalamin injections and high doses are used to detoxify the body. Its advantage is that it does not release any harmful toxins into the body.
  • Methylcobalamin: The great benefit of this biological/active form of vitamin B12 is that the body can process it directly. This substance is biologically identical to vitamin B12, and your liver will have no problem storing it.
  • Adenosylcobalamin: This substance is another active form of vitamin B12. Adenosylcobalamin can also be stored in the liver for your cobalamin reserves.

Aroma

Aromatic substances can be very useful for people who are very sensitive to smells. This is particularly true for children.

Here are the most common types of aromatic substances:

  • Natural aromatic extracts: They come from natural sources such as clove oil, rose water and vanilla.
  • Natural-identical aroma extracts: These extracts are synthetically produced to be biologically identical to the natural versions, such as synthetic vanilla.
  • Artificial flavouring extracts: They are synthetically generated.

We generally recommend that you opt for a natural option.

Summary

We hope this article has helped you understand the role of vitamin B12, an essential nutrient for the proper functioning of our body. Several types of vitamin B12 are available on the market, and you should choose the one best suited to your specific needs.

Vitamin B12 supplementation is particularly important for vegans, vegetarians, and people over the age of fifty. Remember to always be a conscious consumer: don’t be fooled by labels and advertising.
