Hopeful one, I started taking biotin 10,000 mg 2weeks before my surgery and I haven't had any hair loss as of yet I also started my b12 then to. Do not purchase all the protein drinks and powders from your doctor they are expensive I did get the multi vit. But it's hard going down ,I'm on this new product called thrive that has all the vit and nutrients in it ,I started it because of my pain issues and it's like a miracle, I've been in pain with my shoulders and knees for 15 yrs and the day I started thrive it was amazing and the best part of that it's not a narcotic or a prescription,I drink slim fast protein drinks, the key is to get protein and water but it's difficult to drink all the water for me, I drink a lot of crystal lite and it's made with water so that's it for me oh I'm 59 will be 60 in February
