question: I am now on estradoil 0.5mg, lisinopril 10mg, prenatal vitamins (though not pregnant) 1 a day, fish oil 3 a day, and calcium 600 + D usp, and I used to take folic acid which I quit taking. Now my hair which was extremely thick is falling out and I have lost at least 3/4 of the thickness could this be due to not taking folic acid anymore? I am will be 71 this month.  Thank you.
