Vitamin D – The struggle

May 12, 2011 Circadian/Nature, Diet/Insulin, Resources No Comments

There remains a battle going on about what is the best dose – though now little debate about how important having enough D is.

Here in full is the Statement of the Vitamin D Council

Caucasian skin produces approximately 10,000 IU vitamin D in response to 20–30 minutes summer sun exposure. This is over 16 times higher than the US government’s recommendation of 600 IU per day!

This high rate of natural production of vitamin D3 cholecalciferol(pronounced koh·luh·kal·sif·uh·rawl) in the skin is the single most important fact every person should know about vitamin D—a fact that has profound implications for the natural human condition.

Technically not a “vitamin,” vitamin D is in a class by itself. Its metabolic product, calcitriol, is actually a secosteroid hormone that is the key that unlocks binding sites on the human genome. The human genome contains more than 2,700 binding sites for calcitriol; those binding sites are near genes involved in virtually every known major disease of humans.

Current research has implicated vitamin D deficiency as a major factor in the pathology of at least 17 varieties of cancer as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, periodontal disease, and more.

Vitamin D’s influence on key biological functions vital to one’s health and well-being mandates that vitamin D no longer be ignored by the health care industry nor by individuals striving to achieve and maintain a greater state of health.

If well adults and adolescents regularly avoid sunlight exposure, researchindicates a necessity to supplement with at least 5,000 units (IU) of vitamin D daily. To obtain this amount from milk one would need to consume 50 glasses. With a multivitamin more than 10 tablets would be necessary. Neither is advisable.

 

HOW TO GET ENOUGH VITAMIN D

There are 3 ways for adults to ensure adequate levels of vitamin D:

  • regularly receive midday sun exposure in the late spring, summer, and early fall, exposing as much of the skin as possible for 20–30 minutes (being careful to never burn). (Those with dark skin will need longer exposure time — up to six times longer.)
  • regularly use a sun bed (avoiding sunburn) during the colder months.
  • take 5,000 IU per day for 2–3 months, then obtain a 25-hydroxyvitamin D test. Adjust your dosage so that blood levels are between 50–80 ng/mL (or 125–200 nM/L) year-round.

VITAMIN D’S CO-FACTORS

Vitamin D has co-factors that the body needs in order to utilize vitamin D properly. They are:

  • magnesium
  • zinc
  • vitamin K2
  • boron
  • a tiny amount of vitamin A

Magnesium is the most important of these co-factors. In fact, it is common for rising vitamin D levels to exacerbate an underlying magnesium deficiency. If one is having problems supplementing with vitamin D, a magnesium deficiency could be the reason why.

What is the Missing Human Manual All About?

Do you want to age well? Most of us do. If you are my age, 60, this is more important a question that if you are 30. But most of us would not wish to have heart disease, cancer, dementia when we get old.

Most of us think it is normal that we will get ill like this.

But science today tells us that this is not "Normal". Our evolutionary past designed us to be active and fit until we drop dead. Why? Because raising human children takes so long. Mature adults had to do most of the hard work enable us to invest up to 25 years in our kids.

We are designed by our evolution to reach a plateau of fitness in mid life. So why do most of us not live like this?

We don't because, we have strayed away from the best way of living that fits our evolution best. Our culture has got too far ahead of our biology. We eat foods that make us ill. We have lost our social identity and power and that makes us ill. And we have lost touch with the circadian rhythms of the Natural World, and that has made us ill too.

We have lost our fit with our true nature.

This site will be a Manual. It will show you what the best fit is. It will show you the science behind this. It will share with you some methods for getting your fit back with your true human nature.

So welcome to the "Missing Human Manual" . I hope that we can help you and I hope that you can help others as a result.
