اردو میں پڑھیں

Vitamin B12 is one of the thirteen essential vitamins necessary to support life. The primary functions of vitamin B12 are to promote nerve function, maintain healthy blood cells, and aid in the production of DNA, which is the building block of every cell throughout the body.  Usually, a deficiency occurs when the body is unable to properly absorb the vitamin, which is found in specific foods.  Foods that are high in vitamin B12 include eggs, milk, cheese, red meat, white meat, fish, shellfish, and fortified cereals.

Is it good to take a multivitamin every day?

Symptoms of vitamin B12 deficiency include tingling and numbness in the extremities, pale skin, fatigue, cognitive impairment, mood swings, nausea, and vomiting. Vitamin B12 deficiency is diagnosed through blood work, and treatment options include supplements or dietary changes. If a supplement is required, there are many options available, such as pills, sublingual tablets, nasal gels, and shots. Risk factors for this deficiency include pregnancy, alcohol abuse, a vegetarian diet, autoimmune conditions, and intestinal problems.   


While this deficiency can present with unusual symptoms, it is typically readily corrected with the proper supplement or dietary modifications.  If you have been experiencing any of the above symptoms, connect with Shifa4U today and order a vitamin B12 laboratory test online in Pakistan only on Shifa4U.
