How much Folic Acid?

My daughter's gastro did not want her taking too many supplements. However, she is on Purinthol which is the same as Mercaptopurine or 6mp. With this drug she has had hair loss and I am seeing where most people on it take a folic acid supplement. I am going to give this to her to see of the hair loss slows down. It has been a lot. She is 90 pounds and the tabets are in 400 mcgs. I see where 800 mcgs is 1 mg. How much do most of you take daily and what is your weight? Also do you experience anything negative from them to watch for. I do see where possible stomach upset is listed.

Thanks so much for your help.

Thanks so much for the info.

I take 1 mg of folic acid in addition to the amount that is in my multivitamin. I weigh about 155lbs.

I weigh 140 and take 800 mcg. It has helped to slow the hair shedding down alot.  And I am the queen of sensitive tummys and it doesn't bother me at all.  Hugs!

1000mcg = 1mg. Not 800 . Just thought I would correct that for you:) Hope you have good luck with it, I did. I took a low dose of 400mcg.
