D-Fend Your Health (Vitamin D)

face woman in sun wearing hat sun hat sunglasses istock 3921912There’s something about being outside on a bright sunny day that just makes people feel good. We tend to feel more energized, we don’t get sick as much, and we might even smile a little bit more. But now, research is showing that a nice sunny day may do even more for our health, especially when it comes to preventing age-related diseases – all because of a compound we call Vitamin D.

There has been an ever-growing interest in the effects of Vitamin D on total body health for several decades now, and current research continues to confirm the importance of this vital nutrient. So far, Vitamin D deficiency has been implicated in virtually all diseases including heart disease, diabetes, cancer, mood disorders, poor immune function, and osteoporosis. Recently published research has now confirmed that the level of Vitamin D in a person’s blood can significantly increase or decrease their risk of developing both dementia and Alzheimer’s disease.

What Makes Vitamin D so Important?

Vitamin D is a hormone synthesized naturally by your skin when it is exposed to sunlight. When scientists wanted to know which organs required the most Vitamin D, they investigated which organs had the most receptors for Vitamin D. What they discovered was that virtually all organ systems in the body had relatively high concentrations of Vitamin D Receptors, meaning it was important for all of them! More importantly, these Vitamin D receptors were located on the nucleus of the cell where all of your genetic material (DNA) is stored. It turns out that Vitamin D is actually capable of changing how your body expresses certain genes, helping to explain the major role it plays in so many disease states.

Why You Might be Deficient in Vitamin

The most significant source of Vitamin D comes from production in skin when it is exposed
tosunlight, specifically UVB light (not UVA). Unfortunately, we know that excessive exposure to sunlight can also lead to deadly skin cancers like melanoma, so many of us try to avoid direct sunlight by staying indoors, wearing protective clothing, or by using sunscreens. While these are effective methods to prevent skin cancer, they are also effective at decreasing the amount of active Vitamin D in your body. People with darker skin-tones will require more sunlight than those with light complexions to produce the same amount of Vitamin D. Additionally, as you move further away from the equator, less Vitamin D producing sunlight reaches your skin, so you only produce Vitamin D during a few peak hours between 10:00 AM – 3:00 PM during the summer months.

D-Fend Your Health (Vitamin D) Viniferamine Newsletter 11-7-14If you are not getting Vitamin D from sunlight, your other sources are limited to dietary sources like cold water fish (salmon/tuna), dairy, eggs, mushrooms, liver, fortified foods, or dietary supplements. Plant sources, some supplements and even the most common prescription strength 50,000 IU product contain Vitamin D2 (ergocalciferol) which is less potent than the preferred form, Vitamin D3 (cholecalciferol). An important note is that a single serving of Vitamin D fortified whole milk only contains about 100 IU of Vitamin D3 per 8 oz. serving, so to get 1,000 IU of Vitamin D from milk you would have to drink 10 servings containing 1,500 calories and 46 grams of saturated fat!

Current medical practices define Vitamin D deficiency as blood levels lower than 32 nmol/L, based on studies of bone density and development of osteoporosis. However, there is a growing body of evidence that the cutoff level for deficiency should be raised closer to 50 nmol/L. The previously mentioned study on Vitamin D’s effects on dementia and Alzheimer’s disease showed that people with blood levels between 25 – 50 nmol/L were 53% more likely to develop dementia and 70% more likely to develop Alzheimer’s disease, compared to those with levels above 50 nmol/L. People that had severe deficiency, defined as levels below 25 nmol/L, were 125% more likely to develop dementia and 120% more likely to develop Alzheimer’s disease. If your doctor tests your Vitamin D levels, be sure to ask what blood level they consider as the cutoff for deficiency and how they determined that level.

Supplementing Vitamin D

Pharmacist and womanWhile it is extremely rare, it is possible to get too much vitamin D from supplements which can result in too much calcium in the blood (hypercalcemia). For this reason, it is important to work with your healthcare provider and monitor your blood levels while
supplementing Vitamin D to find the dose that works for you. Most people will require a minimum of 2,000 IU daily to get their blood levels above 50 nmol/L, however you should only exceed that dose under supervision of a healthcare provider.
