What are the treatments for a vitamin B12 deficiency?

  • Vitamin B12-fortified grains 
  • Supplements  
  • B12 injections 
  • High-dose oral Vitamin B12 

Treating the deficiency solves the problem but you must make the recommended changes to keep your levels optimal. Such treatments are generally prescribed only when natural solutions are not suitable. This is particularly the case if you have dietary preferences that may restrict you from getting this nutrient in adequate amounts. For example, if you follow a strict vegan diet, you are at a greater risk of developing this deficiency. This is mainly because your diet will not contain animal foods that can give you the required vitamin B12.  

Vitamin B12 is an important nutrient and you must be aware of the adverse effects of a vitamin B12 deficiency. Eating the right food can help and if the deficiency persists, you can get vitamin B12 tablets like Neurobion Forte. While there are several such options, a balanced lifestyle is key to staying healthy. Get proper guidance from dietary and nutrition experts on Bajaj Finserv Health.
