helps support your
immune system



Your body is equipped with powerful natural defences and your immune system has many ways of dealing with threats from bacteria and viruses. The Immune system is made up of three main defence mechanisms; Physical barriers (skin and mucosa), cellular barriers (white blood cells) and antibodies. Nutrients such as vitamins and minerals are essential to the health and function of this complex network.

Living in a fast-paced world can sometimes be challenging to consume adequate amounts of fruits and vegetables daily, which in turn can help to provide your body with the essential vitamins and minerals it needs to fully support bodily functions. An inadequate intake of vitamins and minerals can negatively affect your immune system, and impact your health.
