What is methylcobalamin?

Methylcobalamin is a form of vitamin B12. Vitamin B12 is an important vitamin that your body needs to function properly. There are different forms of vitamin B12; methylcobalamin is a “natural” form, unlike some synthetic forms such as cyanocobalamin.

The most important tasks of methylcobalamin:

• Helps in the production of red blood cells.
• Plays a role in the formation of DNA, the genetic information in your cells.
• Supports your nervous system, among other things, by contributing to the protective layer (myelin) around your nerves.
  

What is methylcobalamin good for?

Energy, nervous system and mood

If you don't have enough B12, you may feel tired, be more irritable, experience tingling in your hands or feet, or have a poorer memory. This is because your body does not produce enough red blood cells and your nerves are less well protected. Methylcobalamin helps prevent or reduce these problems.

Heart and brain health

Vitamin B12, including methylcobalamin, is important for the proper transport of oxygen in your blood. This is necessary for your heart, but also for your brain. It also supports nerve repair, which is especially critical for people with nerve problems or pain.

Role in the body in case of deficiency

If you have a vitamin B12 deficiency, you may experience physical symptoms such as:

• Fatigue
• Pale skin
• Muscle weakness
• Tingling in the hands or feet
• Hair loss
  

Why is methylcobalamin good for your hair?

Healthy hair starts from within. Methylcobalamin, or vitamin B12, plays an important role in this. This vitamin supports processes in your body that directly affect the condition of your hair.

When you have a B12 deficiency, your body is less able to transport oxygen and nutrients to the hair follicles. The result? Your hair becomes weaker and can fall out more quickly. By replenishing your B12 reserves with methylcobalamin, your hair roots will once again have the fuel they need to grow strong and healthy hair.

But even if you don't have a significant deficiency, methylcobalamin B12 can contribute to healthy hair growth. This form of B12:

• Stimulates oxygen transport via the blood, so that your hair roots are optimally nourished.
• Supports cell division and growth of your scalp and hair follicles, which is important for thicker and fuller hair.
• Helps repair nerve fibres, which can support the natural hair growth cycle.

In short: sufficient methylcobalamin in your body not only provides energy and a properly functioning nervous system, but also contributes to a healthy basis for strong, shiny and vital hair.

How to use methylcobalamin: supplements & safe dosage

You can obtain methylcobalamin in various ways:

• Through food: fish, milk, eggs and meat contain vitamin B12. Sometimes it is present in the form of methylcobalamin, although this depends on the source.
• Supplements: these can be in the form of tablets or melt tablets (or under the tongue), capsules, or even injections if the deficiency is severe.

Safe use & dosage

• It is always wise to first check with a doctor or pharmacist to see if you actually have a deficiency.
• The dosage varies per person: age, health, the severity of the deficiency, etc.
• In case of a deficiency, a doctor may prescribe melt tablets or injections.
• Possible side effects are mild, and serious side effects are rare.
• Allergic reactions are something to watch out for.
