The Science of Ageing Well: Vitamin D Optimisation
Most of us have heard of vitamin D, often referred to as the "sunshine vitamin". What many people don't realise is just how important it becomes after menopause.
Vitamin D deficiency is surprisingly common in post-menopausal women. As we age, our skin becomes less efficient at producing vitamin D from sunlight, and many people struggle to maintain optimal levels throughout the year.
This matters because vitamin D is involved in two key aspects of healthy ageing: bone turnover and immune function.
Bones are constantly being broken down and rebuilt in a process known as bone turnover. Following menopause, declining oestrogen levels accelerate bone loss, increasing the risk of osteopenia and osteoporosis. Vitamin D plays a direct role in this process by helping the body absorb calcium and supporting normal bone remodelling.
Vitamin D also plays a vital role in immune health. Researchers have identified vitamin D receptors on many immune cells, highlighting its importance in regulating immune responses and supporting the body's natural defences.
The challenge is that deficiency often goes unnoticed. Symptoms can be vague and may include fatigue, muscle weakness, low mood, frequent infections or general aches and pains. Some people experience no obvious symptoms at all.
While vitamin D may not be the most exciting aspect of healthy ageing, maintaining adequate levels is one of the simplest ways to support both skeletal and immune health in later life.
Because sometimes the foundations of good health are not the flashy interventions. They're the basics we consistently get right.
