Vitamin D and Optimum Health!

by Steven Carney on November 28, 2012

I’m sure you’ve heard about vitamin D. Many research studies have found significant and positive effects for this unique vitamin. Commonly called, “the sunshine vitamin,” vitamin D is more than a vitamin. It’s more of a hormone regulator, and plays a significant role in many aspects of your health and immune function, among other systems.

Vitamin D plays a key role in the following areas:

  • Immune function
  • Inflammation
  • Bone health
  • Heart and artery health
  • Hypertension/high BP
  • Diabetes
  • Arthritis
  • Psoriasis
  • Autoimmune problems
  • Cancer
  • Alzheimer’s/cognition and mood
  • Tooth decay
  • Allergies/asthma
  • MS
  • HIV

As you can see, the list is extensive (but not all inclusive)! That’s partly due to vitamin D’s key role in helping to regulate basic immune function. By doing so it helps to control inflammation, a key driver of many health conditions, autoimmune problems and diseases.

This key role for vitamin D and inflammation has been uncovered in recent years and is now thought to contribute to overall health and longevity in important ways (when your levels are high), and health problems, diseases, and early death if your levels are too low. Estimates indicate that about 50-75% of adults probably have a vitamin D deficiency or insufficiency, especially those in northern latitudes and cloudy climates.

Deficiency to optimum levels

Vitamin D, like other nutrients, is often involved in research to find the best levels, and health practitioners that don’t keep up with research often think older amounts are fine. I’ve also seen them claim that higher levels are just hype to drive vitamin sales. Drug companies and researchers often take the position that vitamins and supplements are “unproven” and “unscientific.” As they adopt and push these self-serving and backward views, they undercut the search for optimum health, giving patients bad advice and pushing drug sales.

So how much vitamin D do you need? Various agencies and experts have differing views but here’s my take on the current guidelines (these may evolve as newer research comes in):

  • Deficiency occurs under 20 ng/ml, resulting in more health problems and disease (see above list)
  • Insufficiency is 20-30 ng/ml, resulting in more colds, flu, allergies and infections
  • Sufficiency is probably 30-40 ng/ml and is a good start at achieving better health with less sickness or disease
  • Optimum is probably 40-50 ng/ml and can begin to help you avoid the conditions and diseases from the list above.

I often recommend levels around 50 ng/ml level, something you can find through a blood test called 25-hydroxy vitamin D. Most people don’t have levels close to 40, let alone 50 ng/ml and they won’t enjoy optimal health or top immune function! Some experts are already recommending levels above 50 ng/ml, but those exact levels and details are driven by individual needs and health conditions. It also depends on how far north you live, what sun exposure you get, sunscreen usage, diet, age, gender, etc.

Dietary sources are inadequate

One reason why people don’t have enough vitamin D is that it’s hard to get enough through diet alone. Some sources are fatty fish, eggs, dairy and mushrooms but it’s hard to eat enough of those foods to achieve optimum blood levels. And with the use of sunscreen, which is recommended to prevent skin cancer, skin absorption from sunlight is cut significantly! Most people need to supplement with vitamin D3, but it is affordable.

Keep in mind that to enjoy wondrous health and great immune function, your nutritional choices and activity also play a role, as do things like stress, smoking and alcohol use. And as vitamin D continues to be researched, it’s role will becom known in even more health and disease conditions.

BTW, note that in the initial list of health conditions and diseases, a doctor visit will often get you a prescription for dozens of possible drugs, none of which will actually cure you! Those health problems are NOT cause by a deficiency of drugs! Health starts with lifestyle and nutrition. The role of drugs is overdone and they should only be used as a last resort!

In order to understand your individual needs and health, drop me a line with questions about vitamin D and how it can help you improve your health and vitality. Just image if you didn’t get a cold or infection this year/season. And how about no colds or flu for the next 3-5 years?

A new pilot study I found on 3/26/13 shows that vitamin D does indeed improve immune and gene function:

This has some additional details of the study and how vitamin D affects almost 300 immune system genes.

I am really loving the theme/design of your weblog. Do you ever run into any web browser compatibility issues?

I’ve seen friends pull up the blog on a smart phone and it seems to work okay. The print is small but most can enlarge a section to read more easily. I haven’t heard of any browser issues so far.
