Vitamin D and iron are two very important essential nutrients required by the body for normal formation and functioning of blood, cells, bones and muscles. Iron plays a vital role in the formation of red blood cells; and parts of proteins such as haemoglobin and myoglobin which help in transporting oxygen throughout the body. Vitamin D helps in regulating calcium absorption and it also helps in regulating blood calcium level. Vitamin D is also required for bone and teeth formation. It is important to maintain the optimum levels of vitamin D and iron in the body in order to avoid various health diseases and disorders. The daily recommended dosage of vitamin D and iron is easily available from the food intake. Hence, planning out the diet carefully is very important.

Heme iron is better absorbed by the body and it is present in animal products such as fish, red meat, poultry etc. Non-heme iron is usually present in plant food such as lentils and beans. It is also found commercially as added iron in iron fortified or enriched foods.
