Our bodies are reliant on vitamins, minerals, essential fats, amino acids and other building blocks to steer our billions of chemical reactions that go on in our body every second of every single day, and without these raw materials, our bodies can’t thrive in the way they deserve.

What is iron?

Iron is a micronutrient that is found in meat, beans, nuts, dried fruit, wholegrains, soy and dark leafy greens. It has a vital role to play when it comes to great health and energy, as well as disease prevention. In fact, iron is needed for more than 300 biochemical reactions in the body.

Iron is just one mineral out of the selection of 13 vitamins, 14 minerals, 20 amino acids, various fatty acids and all the plant nutrients, known as phytonutrients, which we know deliver our body an abundance of health.

Do vegans and vegetarians need more iron?

Our bodies find it much easier to absorb the iron from meat than from plants. This is why vegans and vegetarians can often suffer from iron deficiency (which is when the body doesn't have enough iron).
