I recently underwent a medical checkup, and my report shows that I have a vitamin B12 deficiency. I would like to know how much time it typically takes to recover from B12 deficiency without using any external supplements.

Recovery without supplements may take longer and depends on your diet. However, supplementation (oral or injection) is often advised for quicker improvement. Symptoms usually start improving within 2 to 4 weeks once corrected.

For the past 30 days, I have been unable to taste or smell anything. Additionally, I am experiencing a strange, unpleasant taste that is the same for all types of food, whether spicy or not. I had a COVID 19 test, which came back negative, and I also underwent blood tests, which I have attached.

Hi Sir or Madam, I was having strange sensation on my whole body but after taking Neurobion Forte I am feeling well. Suddenly it started again and after 2 days it went away as I continued the medicine. My question is how long should I take this medicine? Or should I switch to injection or other medicines? This is my blood report.

I recently underwent a full body check up and found that I have Vitamin B12 and Vitamin D deficiencies. My report shows: Vitamin B12: 59 pg/mL Vitamin D: 13.6 ng/mL One doctor suggested taking Meconerve injections (1 ampule IM daily for 5 days, then once a week for 4 weeks, followed by once a month for 12 months).
