It should be corrected with the right combination of supplements, diet, and lifestyle changes.
I would recommend getting the deficiency treated under the guidance of your doctor, as the supplement dose depends on how low your levels are.
● Along with supplementation :-
☆ Include
B12-rich foods such as milk, curd, paneer, eggs, fish, chicken, or fortified cereals (if you're vegetarian).
☆ For
Vitamin D, aim for 15–20 minutes of sunlight exposure (preferably in the morning) on most days, and include foods like egg yolk, fatty fish, fortified dairy products, and mushrooms.
☆ Ensure you're also consuming adequate protein and a balanced diet to support recovery.
