Can taking Vitamin D help eczema?

25 Sept

Autumn has arrived and it feels as if the lights have suddenly gone out! With this seasonal change, comes the need to consider Vitamin D - so can taking Vitamin D help eczema?

Vitamin D, known as the "sunshine vitamin", is synthesised in our skin when exposed to sunlight. Limited sunlight during autumn and winter in the UK can mean that we are not getting enough of this vital vitamin. For those with eczema, season changes can often be a trigger for eczema flare ups. Vitamin D is a key consideration as part of a eczema management protocol.

The Role of Vitamin D

Vitamin D is not only essential for overall health but also plays a significant role in skin health and immune system function.

Immune Function:

Vitamin D possesses immunomodulatory properties, which means it can help regulate the immune system's response. Eczema is a complex condition which is in part immune system related. Vitamin D is thought to have a role in modulating inflammatory responses in the body that contribute to eczema symptoms.

Skin Barrier Function:

Vitamin D is involved in maintaining the skin's barrier function. A robust skin barrier helps prevent moisture loss and the entry of irritants, offering relief from eczema symptoms.

A study published in the Journal of Dermatological Treatment in 2020 reported Vitamin D supplementation, in conjunction with standard eczema treatments, led to improved eczema control and quality of life for participants (Javanbakht et al., 2020 Research Paper ).
