Vitamin D and Osteoporosis


We know by now that we need to eat the right foods, need to work out, and do stuff that is healthy for us. Because maintaining good health does not happen by accident, it requires work and smart lifestyle choices. But sometimes when we wake up at 6 am to hit the gym before work or shunning the donuts in breakfast, it’s easy to lose sight of for what are we doing all these. So here are some top articles choices that can keep you motivated to lead a healthy lifestyle and keep diseases at bay.

Vitamin D and Osteoporosis

There is a strong association between vitamin D (deficiency), bone formation (and bone resorption) and osteoporosis. The severe deficiency state of vitamin D cause rickets in children or osteomalacia in adults. Presently scientific evidences are accumulating which suggests that the vitamin D deficiency state is more prevalent than previously thought by doctors and scientists. The vitamin D deficiency state is more prevalent among individuals at risk such as people living in northern latitudes (especially during winter season among females), malnourished and poorly nourished individuals, people with  mal-absorption, elderly people, individuals with chronic liver or kidney disease. Dark skinned people are also at higher risk of vitamin D deficiency, as the dark skin color filters most of the sunlight and skin is unable to produce vitamin D.

Presently experts suggests that the optimum serum level of 25-hydroxyvitamin-D or 25(OH)D should be more than 75 nmol/L (30 ng/mL) and for an adult to achieve this level of25-hydroxyvitamin-D need to consume approximately 800–1000 units of vitamin D per day, especially individuals who avoid sunlight or routinely use ultraviolet-blocking lotions.

The vitamin D deficiency state results in the development of compensatory secondary hyperparathyroidism and hyperparathyroidism is a risk factor of osteoporosis and fracture as a result. Many studies has shown that more than half of patients admitted to general hospitals have biochemical features of vitamin D deficiency, such as increased levels of PTH (parathyroid hormone), increase alkaline phosphatase and lower levels of ionized calcium.

The prevalence of vitamin D deficiency (mild) is increasing even among apparently healthy ambulatory individuals and adequate consumption of vitamin D (therapeutic or preventive measure) can bring the vitamin D deficiency status to normal and prevent bone remodeling, bone loss, and fractures. Increase intake of vitamin D is helping even individuals living in northern latitudes.

Vitamin D adequacy may also play a causative role in other diseases such as cancers (colorectal, prostate, and breast), autoimmune diseases, diabetes etc.
