Vitamin D !?!

Vitamin D is obtained from sun exposure, food and supplements.

Vitamin D is what's referred to as a steroid vitamin, it encourages the absorption and metabolism of calcium. People who are exposed to natural sunlight on a regular basis tend to get good quantities of vitamin D naturally and do not need vitamin D supplements. Sunlight promotes sufficient vitamin D synthesis in the skin.

For others, living in darker climates, or with constant indoor working conditions they most likely are not getting the sunlight they need to absorb vitamin D properly.

Five forms of vitamin D have been discovered, vitamin D1, D2, D3, D4, D5. The two that are important to humans are vitamins D2,and D3.

A human requires fifteen minutes of sun exposure twice a week on the face, arms, hands, or back without sunscreen with a greater than 3 UV index for adequate amounts of vitamin D absorption.

Reasons you may not have enough Vitamin D...

  • Cloudy weather/overcast skies
  • Pollution and smog
  • Using Sunscreens
  • Diet
  • Work-being primarily indoors with little to zero exposure to sunlight
  • Location-living far from the equator=less sun exposure
  • Age
  • Heredity

Are you deficient?

If you don't have enough Vitamin D in your system, you may exhibit the following symptoms;

  • fatigue
  • Bone pain
  • Joint pain
  • muscle twitches
  • Mood swings
  • Tooth loss, and dental problems
  • High blood pressure
  • Depression

What foods contain Vitamin D?

Not many foods contain vitamin D.

Some fish, such as tuna, mackerel and salmon, as well as fish liver oils are considered to be the best sources. Tuna, shrimp, herring, sardines and oysters are also great sources. Some vitamin D is also present in cheese, egg yolks, fortified milk, beef liver, ham, salami, shiitake and button mushrooms.

Benefits of Vitamin D!!

If you're not getting vitamin D from your diet, you should consider taking a supplement for the following benefits;

  • It promotes calcium balance within the body
  • Regulates blood pressure
  • relieves aches and pains
  • reduces wrinkles
  • aides in insulin secretion
  • Increases energy
  • reduces stress and tension
  • reduces respiratory infections
  • Prevents brittle bones
  • Prevents Rickets
  • Improves kidney function
  • Reduces depression
  • Regulates weight loss and metabolism
  • Boosts immunity
  • Helps Cancer and Hepatitis B, or liver diseases


Because Vitamin D is a fat soluble vitamin (having to much can be bad!), it is important to take vitamin D in proper doses, and check drug interactions for any medications you're taking with a health professional.

The requirement of vitamin D for adults up to 50 years of age is 400-800IU, daily.

When taking Vitamin D, it should include adequate levels of Vitamin K and Magnesium.

      Here is some more interesting information I came across. Note if you find one of my articles on vitamin D it is connected with all the others with the Previous and Next buttons. Many are concerned about high rates of autism and the suffering it causes.

      Some think that it may have to do with toxins like mercury in vaccines even though it was stopped years ago with all single dose vaccines. Also some think that cancer may have to do with toxins. Well they now know that vitamin D greatly helps the body get rid of toxins.

      PubMed (National Library of Medicine) says that vitamin D in pregnant mother and babies lowers the chance of kids getting autism or that autism is caused by a lack of vitamin D in pregnant mother and baby. Psychology Today and Scientific American also say the same thing.

      Moores Cancer Center proposes that cancer may be a vitamin D deficiency. If you look up Michael Holick M.D. under Wikipedia it says that there is a vitamin D deficiency pandemic (widespread epidemic). Note this would explain why so many people are getting cancer and autism. As you move further from the equator rates of cancer, autism and type 1 diabetes go up. [Brighter sunlight means more vitamin D]

      When was the last time you heard that they determined that the RDA was wrong so they had to raise it? In November 2010, the U.S. RDA of vitamin D was tripled! The group called D'Action says that people need lifeguard levels of vitamin D.

      By definition the body cannot make a vitamin. So they now know that vitamin D is actually a neurosteroid hormone. Also if I spend 15 minutes out in the sun in the summer in Southern Arizona my body produces over 10,000 IU of vitamin D.

      My article on how much vitamin D that someone should take for full protection says 8,000 IU of vitamin D daily. They make capsules that contain 5,000 IU of vitamin D. In Finland they gave over 10,000 newborn babies vitamin D everyday and it reduced type 1 diabetes by 80%.

      So the question is how much did they give to the babies since less than what they gave to the babies might not have worked. They gave them 2,000 IU of vitamin D everyday.
