Effective Natural Anemia Remedies

When I was diagnosed anemic back in January, my doctor recommended a natural iron supplement and said come back in 3 months. 3 months later bloods dropped one point from 7 to 6 and it was thought there is a problem with iron absorption. I thought I'll beat this. I took 2 T molasses a day, natural iron tabs, beets nearly every day and every other high iron food I could find.. 4 months later books have dropped to 4 and I'm dragging myself around or in bed. Doctor has suggested a parasite cleanse as I travel to developing countries every year, a colonoscopy to rule out internal bleeding and an iron infusion. Has anyone else had this experience of inability to absorb iron?
