This document discusses haematinics, which are nutrients that help form blood cells. The main haematinics are iron, vitamin B12, and folate. Iron tablets can help restore iron levels if taken on an empty stomach for better absorption. Dietary sources of iron include red meat, seafood, beans, dark leafy greens, dried fruits, and eggs. Iron is distributed throughout the body, with most found in haemoglobin and stored as ferritin and haemosiderin. Ferrous sulfate and ferrous gluconate are examples of inorganic haematinics.
