How much time does it take to recover from memory related issues from
B12 deficiency? I had been having issues (headache, chest pain, tremors) starting from Jan 2023 and started treatment with methycobalamin tablets (1500 mg) and folic acid (5 mg) everyday from Apr 2023 onwards. Now only I experience issues with learning and memorising new things.
Do you have any suggestions for recovering from brain fog in this case?
