Beyond Bones: Vitamin D's Hidden Role in Mood & Energy
22 Nov
Summary
- Vitamin D deficiency is linked to weakened immunity and increased winter illness.
- Low vitamin D can cause chronic fatigue, muscle weakness, and headaches.
- Mental health is affected, with lower levels correlating to depression.
Vitamin D, essential for numerous bodily functions, is often deficient in the UK, affecting an estimated 30-40% of the population during winter months. Beyond its known role in bone health and calcium absorption, this vital hormone plays a crucial part in regulating the immune system, helping the body fend off infections.
Signs of deficiency can extend to chronic fatigue, muscle weakness, and even headaches, impacting daily energy levels and cognitive function. Mental well-being is also significantly influenced, with studies showing a correlation between low vitamin D levels and increased instances of depression.
While sunlight is a primary source, it's limited during autumn and winter. The NHS advises daily supplementation during these months. For vegans, dietary sources are scarce, mainly limited to fortified foods and certain mushrooms, underscoring the challenge of obtaining adequate vitamin D solely through diet.
