‘SUPPLEMENTS LIFTED MY DEPRESSION’

Many people completely disagree with Prof Spector and some claim that daily Vitamin D has helped combat everything from debilitating joint pain to bone problems and even mental illness.

Janet Byrne has polymyalgia rheumatica — an inflammatory disorder that causes muscle pain and stiffness. ‘Three weeks after taking the supplement I felt very much better physically and my depression lifted,’ she said.

Katie Woodiss-Field, 54, says in just three months she went from being too stiff to get out of bed to enjoying five-mile hikes. She says: ‘During lockdown I developed horribly aching legs. They felt as if they’d lost all strength. Blood tests showed I had extremely low levels of Vitamin D. I was prescribed the highest dose you can get over the counter. It was suddenly much easier to walk up the road to the shops. One day, about three months later, the ache just disappeared.’
