Why is vitamin B12 so important?
Simply put, vitamin B12 is like a little hero that performs several very important functions in our body. We also call it cobalamin.
Think of our body as a big factory that is constantly working. Vitamin B12 is essential for this factory to function properly. Mainly, it is important for three reasons:
1. Make red blood cells: When we breathe, the oxygen that comes into the lungs is carried to all parts of the body by red blood cells. Vitamin B12 is needed to make these vehicles called red blood cells properly. If there is not enough B12, healthy red blood cells cannot be made. We call this anemia.
2. Keep the nervous system healthy: The nervous system is the 'wire system' that carries messages between our brain and the rest of the body. Vitamin B12 is essential for the healthy functioning of this nervous system. This is especially important for the brain development of young children.
3. For DNA production: Vitamin B12 also helps in the production of DNA , the genetic information store in our body's cells.
Our bodies cannot make vitamin B12 on their own, so we must get it from food or vitamin supplements.
| Foods rich in vitamin B12 | Examples |
|---|---|
| Meats | Things like beef, chicken, liver |
| Fish and seafood | Crab, squid, salmon, crab, shrimp |
| Milk and dairy products | Cow's milk, yogurt, cheese |
| Eggs | Chicken eggs, quail eggs |
| Fortified Foods | Some breakfast cereals, nutritional yeast |
Pregnant and breastfeeding mothers need more vitamin B12 than normal, because the baby also gets that vitamin from the mother.
How does a child develop B12 deficiency?
There can be several main reasons why a child may develop this condition.
1. Dietary problems
This is the most common reason. Children who follow a completely vegan or mostly vegetarian diet miss out on foods that naturally provide vitamin B12, such as meat, fish, milk, and eggs. In such cases, it is very important to give a vitamin B12 supplement, as advised by a doctor.
2. Difficulty absorbing vitamins into the body
Sometimes, even if a child eats foods that contain B12, their body can't absorb it properly. This can be due to:
- Digestive system diseases: Some intestinal conditions can impair vitamin absorption.
- Pernicious Anemia: This is a rare autoimmune disease in which the body destroys a protein that helps absorb B12.
- Stomach surgery: If you have had surgery to remove part of your stomach for any reason, your absorption of vitamin B12 may be reduced.
3. Low maternal B12 levels
When a baby is in the womb, it stores the B12 it needs from its mother's body. So, if the mother's B12 levels are low during pregnancy, the baby will also receive less. As a result, the baby's stored B12 can quickly run out and begin to show signs of deficiency by about 4 to 6 months of age.
Clinical vitamins and nutritional supplements
Clinically proven high quality vitamins, minerals and immune nutritional supplements.

When should I see a doctor? What are the treatments?
If you suspect that your child has one or more of the symptoms mentioned above, especially developmental delays , be sure to discuss it with your doctor.
Never ignore these symptoms. B12 deficiency is a condition that can cause serious damage to the nervous system and brain if left untreated. However, if detected early, it can be completely cured.
The doctor will examine the child, ask you for details, and if necessary, order a blood test to check the vitamin B12 level.
If a deficiency is confirmed, treatment will be determined based on the cause.
- If there is a dietary problem: The doctor will often prescribe a vitamin B12 supplement (tablets or syrup) for the child. He will also advise adding a diet rich in B12.
- If you have an absorption problem: Your body may not be able to absorb B12 from food or pills, so you may need to get vitamin B12 injections . This is an injection that is given directly into the muscle. Don't worry, this is a very common and safe treatment.
The most important thing is, never give your child vitamin pills from a pharmacy at any time. The doctor should decide everything, such as the dosage and the time of administration.
