I'm Anemic..& I need help building up my red blood cells.?

If you are low in red blood cells, something in your body is not working right and that is why you are going to have the bone marrow biopsy. There is nothing you can do to "beef up" your red blood cells. If the system that makes the red blood cells is not functioning right, there is nothing that can be done until the cause is found and then the cause is treated (often with medications). Meats and dark green veggies are for iron levels, not your red blood cells.
