The innate immune system is first and best known for a family of white blood cells called phagocytes, which reside very close to the layer of epithelial cells that line much of the body's surface.

The iron content of the body is highly conserved (Bothwell et al 1979). To achieve iron balance, adult men need to absorb about 1 mg/day and adult menstruating women about 1.5 mg/day, although this is highly variable. Towards the end of pregnancy, the absorption of 4-5 mg/day is necessary. Requirements are higher during periods of rapid growth in early childhood and adolescence.
How much iron do I need? The amount of iron you need is: 8.7mg a day for men over 18; 14.8mg a day for women aged 19-50 years; 8.7mg a day for women over 50; You should be able to get all the iron you need from your daily diet. Women who lose a lot of blood during their monthly period (heavy periods) are at higher risk of iron deficiency anaemia and may need to take iron supplements.
