Iron is an essential mineral found in every cell of the human body. Its main function is to help make red blood cells which store and carry oxygen in the blood.
If you don’t have enough iron, your body can’t make enough red blood cells. And without enough oxygen, you’ll quickly feel weak, lethargic or exhausted. This tiredness can affect everything from your fitness levels, to brain function to your ability to fight off colds and infection. Lack of iron literally slows you down.
Iron also plays a key role in the conversion of blood sugar to energy and for the efficient functioning of the nervous system.
Your body can’t produce iron so it’s essential you consume enough iron through your diet. However, iron is a notoriously tricky mineral to absorb. It’s estimated we absorb just 10% of the iron we ingest, making it difficult to get your daily quota through food alone.
