I'm taking prenatal vitamins and i'm worried about taking in too much iron as an anmeic. How much is too much?

I'm taking prenatal vitamins and i'm worried about taking in too much iron as an anmeic. How much is too much?

Good question: You need to monitor your blood level of iron and ferritin. Also you may need to check a few other things such as serum folate (folic acid) and b12. The size and hemaglobin concentration on the basic CBC blood test is a start. If you have a low rbc count and your rbc size is small (low mcv) you may have iron deficiency. If the red cells are larger than normal think low folate (folic acid) or low b12. ...Read more

I take 4 mg of folic acid per day with 10 mg Methotrexate weekly. Is this too much folic acid?

I take 4 mg of folic acid per day with 10 mg Methotrexate weekly. Is this too much folic acid?

The most common dose is 1 mg per day, but doses range from 5 - 10 mg weekly. 4 mg/day seems higher than usually recommended. There is some concern that too much folic acid might reduce the effectiveness of Methotrexate. Needs review with your doctor. Good wishes! ...Read more

Is it safe to consume detox drink, niacin 500 mg, and antioxidents?

Detox: What is in the detox drink? What antioxidants are you speaking of?
