Tired All the Time? How Low Vitamin D Could Be Affecting You

Feeling Tired or Down? It Could Be Your Vitamin D

Do you wake up feeling fatigued, struggle with mood changes or find yourself catching colds more often than usual? Many people in the UK experience these non-specific symptoms and blame them on a busy lifestyle, but vitamin D deficiency could be the hidden culprit.

What Are the Common Symptoms of Low Vitamin D?

• Persistent tiredness and lack of energy
• Depressed mood or low motivation
• Muscle aches and bone discomfort
• Frequent infections, like coughs or colds
• Poor wound healing

These symptoms are surprisingly common—especially during the winter months when sunlight is limited in the UK.

"Vitamin D plays a crucial role in many bodily processes—particularly immune defence and energy metabolism."

Why Does Vitamin D Matter?

Vitamin D helps regulate how your body absorbs calcium and phosphate, which keep bones, teeth and muscles healthy. Inadequate levels can lead to weak bones, increased risk of illness and even mental health issues. Many UK adults have lower levels than recommended, especially in autumn and winter.

How Can You Raise Your Vitamin D?

• Spend short periods in direct sunlight (spring and summer)
• Eat foods rich in vitamin D such as oily fish, eggs and fortified cereals
• Consider supplements, particularly in winter (always check with a GP)

However, the only way to know if you’re truly deficient is to test your vitamin D levels.

With the Mayfield Clinic Vitamin D Blood Test Kit (25-OH) – Self-Collect, you can check your levels quickly and easily at home with a finger-prick blood sample (TDL Tiny Kit). You’ll receive rapid results in 1 working day after your sample arrives at the lab.
