Vitamin B12 Deficiency: Due to today's unhealthy lifestyle, people often face deficiencies in essential vitamins and minerals. Vitamins are as important as other nutrients for a healthy body. Vitamin B12, also known as cobalamin, is especially crucial for physical development and mental health. This vitamin helps in the formation of DNA (Deoxyribonucleic acid) and red blood cells (RBCs). It also helps in the proper functioning of the brain and nervous system. Since B12 is not produced naturally in the body, special attention to diet is necessary to supplement it.
Signs & Symptoms Vitamin-B12 Deficiency: These symptoms appear in the body due to deficiency of Vitamin B12.
1. Muscle pain

If your body's levels of vitamin B12 and vitamin D are low, it can lead to muscle weakness and pain. Chronic muscle pain may indicate this deficiency. Therefore, get your levels of both vitamins checked.
2. Fatigue and weakness

A B12 and D deficiency can cause a person to feel constantly tired. One reason for this is that a B12 deficiency prevents the body from absorbing iron properly, which can lead to anemia. Symptoms of anemia include fatigue and weakness.
3. Tingling in hands and feet

Vitamin B12 deficiency can cause tingling or numbness in the hands and feet. If this happens repeatedly, don't ignore it. This problem can affect your nerves, so it's important to get your vitamin B12 and D levels checked.
4. Weak memory

Deficiency in these two vitamins can affect brain function. This can lead to memory loss and even brain fog. Therefore, it is very important to maintain normal levels of B12 and D.
5. Mental stress

Vitamin B12 and D deficiencies can also affect mental health. B12 deficiency reduces serotonin levels, which can affect mood and lead to depression and anxiety. It can also lead to mental and neurological problems.
Vitamin-B12 Deficiency Prevention: Complete Vitamin B12 deficiency with these things
To overcome B12 deficiency, it's crucial to maintain good digestive health, or gut health. A balance of good bacteria in the intestines and improved digestion help with nutrient absorption. Include B12-rich foods in your diet.
Vegetarians can consume fortified foods (such as B12-fortified milk and cereals). Products like milk, yogurt, and buttermilk are also good sources of B12 and support gut health.
Non-vegetarian foods like eggs, meat, and fish are also rich sources of this vitamin. If you don't get enough B12 from your diet, taking supplements after consulting a doctor is an option. Additionally, if your body isn't absorbing nutrients properly, you should consult a doctor.
