The GP describes vitamin D as “a fat-soluble vitamin important for bone health”.
He added: “For those low in this nutrient, increasing intake may also reduce depression and improve strength. If you’re thinking about taking Vitamin D supplements in the first instance contact your GP.”
While anyone can develop a vitamin D deficiency, some are more vulnerable than others and it can have an impact on our mood too.
Dr Perry says: “Vitamin D deficiency has more impact on post-menopausal women than it would men. Vitamin D is often referred to as “the happy hormone’ this is because sunlight increases serotonin levels which in turn may make you happier.
“Serotonin – the body’s natural happy hormone is an important chemical and neurotransmitter in the human body. It is believed to help regulate mood and social behaviour, appetite and digestion, sleep, memory, and sexual desire.”
