This number is doubled for a vegan/vegetarian diet (so adult vegan males need approximately 16 mg/day). The RDA is set so that 97.5% of the population in that age range would meet their requirement if they consumed that amount. Adverse effects from excessive consumption occur above 45 mg per day (this is usually constipation & darker/black stools). Children are at greatest risk of iron toxicity because their daily requirements are so much lower. There have been issues with over consumption of iron fortified infant cereal. Calcium & zinc compete & therefore less iron is absorbed if consumed with those minerals. Some other things that decrease iron absorption are tannins in tea & coffee, phytic acid in soy, oxalic acid in spinach. Fiber (in beans, cereals, etc) also decreases absorption. Things that increase absorption are heme iron & vitamin C (peppers, citrus, broccoli, etc). http://ods.od.nih.gov/factsheets/iron.asp Since the body does not have an efficient way of excreting iron, it can accumulate with excess consumption. Menstruating females lose iron via monthly cycles. Males would have to donate blood. So, you would have to ask yourself if you are experiencing any side effects? The ODS website has more side effects listed. Given all of the things that inhibit absorption of iron, I would say that it would balance out from what you are eating. If you are eligible & willing to donate, a cheap way to get your hemoglobin checked would be to visit Red Cross to donate blood. Hemoglobin does not reflect iron stores though. For some perspective. The treatment for low iron stores in iron deficiency anemia is 65mg of elemental iron (or 325 ferrous sulfate) twice a day for approximately 3 months. 130 mg per day is far above the upper limit and yet it is an accepted treatment for iron deficiency anemia. I'm not sure if the treatment is specific to females. Males could develop iron deficiency anemia as well, although less likely unless they are losing blood regularly.
