Let’s talk about a common problem that many people in Seattle or other places that do not get enough sunlight face and that is Hypovitaminosis D, better known as vitamin D deficiency. Vitamin D is a fat-soluble vitamin that can be mostly obtained through sun exposure. Some food sources such as the flesh of fatty fish (such as salmon, tuna, and mackerel), fish liver oils, beef liver, cheese, and egg yolks provide minimal amounst of vitamin D.
Who does not get enough vitamin D?
People who do not live in sunny areas, such as our beautiful Seattle.
Older people, since their skin cannot synthesize vitamin D efficiently.
People who have darker skin because of having more melatonin in their epidermal layer.
People with inflammatory bowel disease and other conditions that have fat malabsorption issues because of vitamin D being a fat-soluble vitamin.
People who are obese, since the subcutaneous fat confiscate more of the vitamin D that is synthesized in skin and changes its release into the blood circulation.
Why vitamin D is needed?
Having a low vitamin D level puts you at risk for many health conditions such as:
Osteoporosis or low bone mass – for getting calcium into the bone, vitamin D along with vitamin K is needed.
Increased risks of developing type 2 diabetes – some researches have shown vitamin D deficiency can result in impaired glucose metabolism and insulin resistance.
Frequent cold and flu – Vitamin D up-regulates the immune system genes, therefore fighting with viral and bacterial invasions more effectively.
Autoimmune disease such as multiple sclerosis, IBD, Hashimoto thyroiditis, etc. – Vitamin D modulates the immune system, consequently preventing the abnormal immune response.
Increased risk of heart disease, stroke and hypertension – Vitamin D helps to regulate blood pressure as well as kidney function.
Cancer – Vitamin D inhibits multiplication of abnormal cells.
Obtaining adequate vitamin D solely from food sources is difficult. The best route to get our vitamin D, which is sunlight, is very limited in some areas; therefore, supplementation will be the next best option. I always recommend liquid vitamin D for the best results; however, the dosing depends on your vitamin D level, which can be checked through a simple blood test. At sageMED we focus on prevention.
