Corpus luteum - Development and structure. 1  The corpus luteum develops from an ovarian follicle during the luteal phase of the menstrual cycle or oestrous cycle, following the release of a secondary oocyte from the follicle during ovulation.
Iron found in foods is either in the form of heme or non-heme iron. Heme iron is better absorbed than non-heme iron. Foods containing heme iron are the best for increasing or maintaining healthy iron levels. Such foods include (in order of iron-richness) clams, oysters, organ meats, beef, pork, poultry, and fish.
Iron-rich sources include: green leafy vegetables, (such as spinach, collard greens and kale), wheat germ, whole grain breads and cereals, raisins, and molasses. If you have been diagnosed with iron deficiency anaemia or you are pregnant or breast feeding, vitamin pills or tablets may be needed to provide extra iron.
