Hookworm

Hookworm infection comes from parasitic worms that live in the soil, enter through the skin (often bare feet), and settle in the intestines, where they attach to the gut lining and feed on blood. Among supplements, iron has the strongest case because the ongoing blood loss can leave people short of iron and anemic, but little research on it has been reviewed here so far. Folate, vitamin B12, vitamin A, zinc and vitamin C have a more modest case, mostly for supporting recovery from anemia and immune function.
