I have high lymphocytes from past 7-8 years, also low
vitamin b12 & d3 from last 7-8 years and lower side
ferritin but iron level normal and huge hair fall (every where hair in my room ) Even I eat very healthy food and exercise & take multivitamin but still deficiency happen. Only high dose of supplements help to maintain normal level b12 & d3
Please tell me how I correct this and which specialist doctor I have to consult?
