Vitamin D Deficiency More Prevalent In Winter.... Experts Say Get Tested.

Vitamin D is much more than a vitamin; technically it’s a hormone. Vitamin D is manufactured through exposure to direct sunlight. Once it is metabolized and absorbed, it has profound benefits in nearly every aspect of immunity.

Vitamin D deficiency increases risk for acute sickness as well as susceptibility to chronic diseases, including cancer.

It’s no coincidence that the number of coughs and colds increase in the winter when sunlight is at seasonal low in most climates. The American Journal of Public Health sites over 60 studies that implicate a protective relationship that vitamin D has over cancer. The European Journal of Clinical Nutrition reported that children with low vitamin D levels were 11 times more susceptible to respiratory infections.

The best way to know if you are vitamin D deficient is through a simple blood test. Seek a qualified practitioner who can order a serum 25-hydroxyvitamin D [25 (OH) D] test. The baseline minimum should be 30 ng/mL, although evidence is mounting to establish higher levels for optimal health and cancer prevention. The Vitamin D Council recommends enough sunlight, supplementation and/or artificial light to maintain levels between 80-100 ng/mL year round. Supplementation to increase levels of vitamin D can also be surprisingly inexpensive, especially when one looks at the cost of sick care.

Older adults require higher amounts of vitamin D due to an inability to absorb it efficiently. Research has shown that blacks may require as much as two times the sun exposure to accumulate the same amounts of vitamin D.

The American Journal of Clinical Nutrition performed a study on vitamin D supplementation that showed a decreased incidence of cancer by over 75% compared to those in the placebo group who were given a sugar pill. The best food sources of vitamin D are fatty fish, eggs, meat and mushrooms. Although most people think of vitamin D for osteoporosis prevention it also assists in reducing inflammation and improving neuromuscular function. The Vitamin D Council recommends 2000 IU per day in the summer and 5000 IU in the winter. The Canadian Cancer Society has now officially recommended vitamin D supplements to help reduce risk of cancer.
