B12 – anti-fatigue vitamin

B12 - anti-fatigue vitamin

Why do we need B12?

Fatigue, weakness, lack of energy, unwillingness to get out of bed in the morning – these symptoms are familiar to each of us, and they are especially pronounced in winter, when the days are so short and natural light is obscenely scarce.

Of course, feeling tired after a long day at work is completely normal, however, if you do not feel rested even after a full eight hours of sleep, this is already a reason to think about and take a closer look at your health and nutrition.

One of the reasons for fatigue and lack of energy can be a lack of vitamin B12 in the body. I will tell you, my dear readers, how to recognize the lack of this vitamin, and how to replenish its reserves.

Why do we need B12?

B12 is a vitamin that regulates the maturation of red blood cells, erythrocytes. With a sufficient amount of vitamin, red blood cells develop well and effectively cope with their main task – to deliver oxygen to all cells of the body.

In the absence of B12, the normal development of blood cells is disrupted, their number drops, and the person may develop anemia. In 1934, three American scientists from Harvard received the Nobel Prize for the discovery of B12, which they isolated from the liver of anemic dogs. Since then, this vitamin has been the main helper of humanity in the fight against low hemoglobin.

In addition to anemia, prolonged vitamin B12 deficiency can damage the nervous system. With a lack of B12, the normal formation of the nerve myelin sheaths is disrupted, the nerves are “exposed”, which threatens with loss of sensitivity in the arms and legs, loss of balance, memory impairment, disorientation in space and sudden mood swings.

Unfortunately, people often notice these symptoms when the changes that have occurred are already irreversible. B12 deficiency can also lead to the development of clinical depression.

Scientific research indicates that B12 is involved in bone formation and growth. This is especially important for women during menopause, in whom hormonal changes lead to bone loss.

How do you know if you are missing B12?

Dear ones, be alert if you notice the following symptoms in yourself or your loved ones: chronic fatigue, irritability, dizziness, ringing in the ears, drowsiness, poor digestion, headaches, memory impairment, blurred vision, shortness of breath, or, as it already was mentioned, anemia.

With the listed symptoms, it is advisable to donate blood for analysis and check if there is a lack of B12 in the body. If a vitamin is truly lacking, you need to replenish your supply with B12-rich foods or vitamin supplements.

Sources of vitamin B12

Vegetable Animals Seafood
Soy and soy products, seaweed, yeast, peas, beans, lentils Turkey, eggs Octopus, herring, mussels, mackerel, perch

Deficiency of vitamin B12 can appear due to an unbalanced diet, or with stomach ulcers and gastritis, when the normal absorption of the vitamin in the digestive tract is disrupted. The largest supply of B12 is found in animal products, primarily in beef and pork liver.

Therefore, if you, like me, do not eat meat, then try to enrich your diet with soy products, which also contain this important vitamin for the body. The recommended daily intake of B12 for children is 1.2 – 1.8 micrograms per day, for adults – 2.4 micrograms, and during pregnancy and lactation, the rate rises to 2.8 micrograms.

B12 in vitamin complexes

If tests show that you are not getting enough vitamin from food, then I can recommend taking vitamin B12 supplements. Now many companies produce B12 in tablets or capsules, in a convenient dosage, and only one tablet a day is enough to cover the daily requirement.

For example, we take these vitamins with the whole family. If you are a vegetarian, be sure to pay attention to dietary supplements with B12, because plant foods are not the most reliable source of this vitamin!

It is also worth taking vitamins if you are actively involved in sports, are exposed to high mental and mental stress, or are recovering from an injury or illness, and are carrying a baby or breastfeeding.

Contraindications for taking vitamins

In general, B12 is perfectly safe, but vitamins should not be taken in case of some serious medical conditions, such as high hemoglobin or vascular problems. And of course, as with any drug, do not exceed the daily dose!

I completely agree with the catch phrase “forewarned is forearmed!”. If we know how the lack of this or that substance affects our well-being, it is much easier for us to recognize this lack and fill it.

After all, our body is a complex mechanism, and we need to make sure that we provide it with everything it needs. Of course, a balanced diet should come first, but if you have a busy schedule and your body is under stress, you can help it with vitamins.

So, my dear readers, if you want to always be healthy, vigorous and energetic, be sure to include B12 in your diet.
