Why so many people underestimate vitamin B12 – are you affected?
Do you often feel tired, listless or have difficulty concentrating? Perhaps you are affected without knowing it. Vitamin B12 is often described as an underestimated nutrient, although it is vital for our bodies. But many people - especially in Germany - have a vitamin B12 deficiency without being aware of it. In this article, you will learn why vitamin B12 is so essential, who is at risk, how you can recognize a deficiency and how you can prevent or treat it.
What is vitamin B12 and why is it so important?
Vitamin B12, too cobalamin is a water-soluble vitamin that is needed in almost every cell in your body. It plays a key role in the formation of red blood cells, DNA synthesis and the function of your nervous system. Without vitamin B12, literally nothing in your body works properly.
A small nutrient – big impact:
Think of vitamin B12 as the invisible engine of your body. It ensures that you have energy, your nerves work smoothly and your brain remains efficient. Sounds essential, right? But here lies the problem: Our body cannot produce vitamin B12 itself. We rely on getting it through food or supplements.
Why is vitamin B12 so often underestimated?
There are several reasons why many people are unaware of vitamin B12:
- Creeping deficiency:
Vitamin B12 deficiency often develops slowly and goes unnoticed for a long time. Symptoms such as tiredness or difficulty concentrating are often attributed to other causes, such as stress or lack of sleep. - Ignorance about risk groups:
Many people do not realize that certain groups are particularly at risk, including vegans, vegetarians, the elderly and those with gastrointestinal diseases. - Confusion about nutrition:
Since vitamin B12 is found almost exclusively in animal products, many people think that they are well supplied with it through a "normal" diet. But even meat eaters can suffer from a deficiency, for example due to absorption problems.
Who is particularly at risk?
1. Vegans and vegetarians
Since vitamin B12 is mainly found in animal products such as meat, fish, eggs and milk, people who completely avoid animal products are particularly susceptible. Plant-based foods such as algae or fermented products contain only minimal amounts of usable vitamin B12.
2. Elderly people
As we age, the body's ability to absorb vitamin B12 from food decreases. This is often due to reduced stomach acid production, which is necessary to extract B12 from food.
3. people with gastrointestinal problems
Diseases such as Crohn's disease, celiac disease or inflammation of the gastric mucosa can significantly impair the absorption of vitamin B12. There is also an increased risk after stomach or intestinal surgery (e.g. gastric bypass).
4. Pregnant and lactating women
Since the need for vitamin B12 increases during pregnancy and breastfeeding, women can easily become deficient during this phase of life – especially if they follow a vegetarian or vegan diet.
How does a vitamin B12 deficiency manifest itself?
The symptoms of a vitamin B12 deficiency are varied and can easily be overlooked. Common signs are:
- fatigue and weakness
- concentration problems or "brain fog"
- tingling or numbness in the hands and feet
- Paleness Tops
- mood swings and even depression
- palpitations or shortness of breath
- muscle twitching
A long-term deficiency can even lead to permanent nerve damage – so it should not be taken lightly.
Scientific Studies: Vitamin B12 in Focus
A 2018 study published in Journal of Clinical Medicine, showed that about 6% of younger people and up to 20% of those over 60 have a vitamin B12 deficiency. What is particularly alarming is that many of those affected were unaware of their deficiency, as symptoms are often unspecific.
Another study found that the deficiency is particularly common among vegans and vegetarians. According to the German Nutrition Society (DGE), people who eat a plant-based diet should definitely supplement with B12 preparationsto prevent deficiency symptoms.
How can you check your vitamin B12 levels?
- Blood test at the doctor:
The easiest way to determine a deficiency is a blood test that measures the vitamin B12 level in the serum. - Holo-TC test:
A slightly more accurate test is the holo-transcobalamin test. It measures the “active” vitamin B12 in the blood that is actually available to the body. - Homocysteine measurement:
An elevated homocysteine level can also indicate a vitamin B12 deficiency.
What can you do if there is a deficiency?
- Ernährung anpassen:
Meat, fish, eggs and dairy products are the best natural sources of vitamin B12. If you are vegetarian or vegan, you should definitely use fortified foods or supplements. - Food supplements:
Vitamin B12 supplements are available in various forms, including tablets, drops and injections. Injections can be particularly useful in cases of severe deficiency, as the vitamin enters the blood directly. - Regular controll:
Even if you supplement, it is important to have your vitamin B12 levels checked regularly to ensure your body is getting enough.
