Energy is essential for everything the body does, from movement and concentration to everyday bodily functions.
At a cellular level, energy is produced inside structures called mitochondria. Here, nutrients from the foods we eat are converted into a molecule known as adenosine triphosphate (ATP), which provides energy for cells throughout the body.


Mitochondria are often described as the body’s ‘energy factories.’ They use oxygen and nutrients from food to help produce ATP, the form of energy the body relies on to power daily activities.
To support these natural processes, the body depends on a range of nutrients that help maintain normal energy metabolism and overall vitality.


B vitamins play an important role in how the body converts food into usable energy. Rather than providing energy directly, they help support the processes that release energy from carbohydrates, fats and proteins.
When the body does not have enough of certain B vitamins, these processes may not work as efficiently, which can contribute to feelings of tiredness or fatigue.


Energy levels are also linked to how well oxygen is delivered throughout the body. Iron is a key component of haemoglobin, a protein in red blood cells that carries oxygen from the lungs to tissues and organs.
Adequate iron levels help support normal oxygen transport in the body, which is important for maintaining energy levels and overall wellbeing.
