Vitamin D in sleep, pain and early menopause

Vitamin D, sleep and pain

It’s well known that vitamin D plays many beneficial roles around the body including immunity support and calcium regulation. What’s less known is its role in assisting sleep and pain management. A new review study demonstrates that low vitamin D levels are associated with elevated pain (in rheumatic disorders and fibromyalgia) as well as irregular sleep patterns. The mechanism of vitamin D, in this case, is suggested to be related to the regulation of neurotransmitters in the body. The study author concludes that vitamin D supplementation is associated with the therapeutic improvement of sleep and the prevention and treatment of chronic pain conditions.

Vitamin D, Calcium and early menopause

Early menopause (i.e. before the age of 45) affects approximately 10% of woman and is associated with elevated cardiovascular disease risk and osteoporosis. New research published in the American Journal of Clinical Nutrition has identified a link with early menopause and insufficient vitamin D. The study involving over 2000+ women demonstrated that those with high intakes of vitamin D (and calcium) were at 17% reduced risk of developing early menopause than those with lower intakes. Calcium is readily obtained from the diet, but vitamin D which is typically synthesized via sunlight is a common insufficiency in the UK.

Vitamin D deficiency

A clinical review published in the Journal of the American Osteopathic Association (May 2017) found that almost 1 billion individuals worldwide may have insufficient or deficient levels of vitamin D. The cause for this is multifaceted, though the main reason cited is that people are spending more time indoors and applying sunscreen when they go outside, to protect from skin cancer. While this is a healthy skin habit, SPF use does limit vitamin D biosynthesis. Chronic diseases such as kidney disease and even type 2 diabetes greatly reduce vitamin D synthesis as well. Ongoing research is linking vitamin D deficiency with multiple sclerosis, autoimmune disorders, infections, respiratory disease and cancer.Vitamin D Supplementation
