Energy Support: Three Essential Nutrients for Everyday Energy

Energy Support: Three Essential Nutrients for Everyday Energy

Sep 05, 2026Vicki Fletcher

Energy is something we often take for granted until we don’t have quite enough of it. With so many single-nutrient supplements available, it is easy to feel overwhelmed by choice and harder still to understand the role each nutrient plays.

That is why we brought together iron, magnesium and vitamin D3 in our Energy Support combination. Each has a different nutritional role: iron and magnesium contribute to normal energy-yielding metabolism and the reduction of tiredness and fatigue, while vitamin D contributes to the maintenance of normal muscle function.

Understanding these roles helps explain why we selected them and how they fit into an overall approach to everyday nutrition.

Iron: Supporting Oxygen Transport and Energy Metabolism

Iron plays an important role in the body’s ability to transport oxygen. It contributes to the normal formation of red blood cells and haemoglobin, the protein in red blood cells that carries oxygen around the body.

Iron also contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue. These recognised functions make it an important part of our Energy Support combination.

Our Iron Bisglycinate 20mg with Vitamin C support both functions and are enhanced with added vitamin C to help increase iron absorption.

Iron supplementation is not appropriate for everyone, however. Feeling tired does not necessarily mean you need more iron. If you are concerned about your iron levels, speak to a healthcare professional before supplementing.

Magnesium: Helping the Body Turn Food into Energy

Magnesium is involved in many processes within the body, including normal energy-yielding metabolism. It also contributes to a reduction of tiredness and fatigue and supports normal muscle and nervous system function. In other words, magnesium has a role in helping the body make use of the energy provided by food. 

We pair our Magnesium with Vitamin B6, which also contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue. By helping enzymes process nutrients and break down glycogen from carbohydrates, Vitamin B plays a complementary role in using food for energy, making it a considered addition to the combination.

Vitamin D3: Supporting Normal Muscle Function

Vitamin D has several important roles in the body, including contributing to the maintenance of healthy bones and the immune system.

Rather than presenting it as a direct energy booster, like that of iron and magnesium, we’ve selected Vitamin D3 for its contribution to normal muscle function. [EC1] By supporting the absorption of calcium, which is key for healthy muscles, Vitamin D supports to the physical side of everyday activity, such as walking or climbing stairs.

However, it’s difficult to obtain enough Vitamin D during the darker months in the UK. Between October and early March, we do not make enough vitamin D from sunlight alone, so the NHS advises adults to consider daily supplementation during autumn and winter.[EC2] 

Our Vitamin D3 [EC3] provides a convenient way to supplement your intake and support your energy and immunity throughout the colder months.

Why consider these supplements to support your energy

If you’re looking to boost your energy levels, this trio has been specifically selected to support different parts of the body’s normal processes:

·        Iron contributes to normal oxygen transportation, helping reduce tiredness.

·        Magnesium and Vitamin B6 contribute to normal energy-yielding metabolism and the reduction of fatigue.

·        Vitamin D contributes to the maintenance of normal muscle function, which matters for everyday movement.

Together, these supplements offer a convenient way to top up your intake of nutrients that support normal energy metabolism and muscle function.

Three nutrients. Three different roles. One simple approach to supporting your energy.
