How Much Vitamin D?

The Institute of Medicine recently published a report on a

Vitamin D3 From the Sun

Vitamin D3 From the Sun

study they did concerning how much
Vitamin D is necessary.  Their conclusion,
according the New York Times was that
“most of us” get plenty of Vitamin D.

Referring to the same article, WebMD
encouraged us to:  “Triple Vitamin D Intake.”
There are several factors to consider:

  • What is the reporter’s bias on the subject?
  • What kind of Vitamin D are they reporting on?
  • How is our need for Vitamin D affected by our
    geographical location?

So how much Vitamin D do we need?

When we read these “news” stories, it is almost like reading political news.  We must realize that the reporter may put a spin on the article by reporting only the part of the study that agrees with his previous opinion instead of reporting objectively.

Then we need to analyze the report to see whether it has all the facts.  To speak of Vitamin D without distinguishing between Vitamin D2 ( the synthetic, useless kind) or Vitamin D3 ( the natural, beneficial kind) makes the report of no value.  There is a great deal of difference, and the Vitamin D in most products is the synthetic kind because it is so cheap to produce.

Another important factor lacking in this report is the need for greater amounts in locations where there is little sunshine, or for people who do not get out in the sunshine or who wear sunscreen or clothing that completely covers the skin.  If those conditions apply, or if you have dark skin, you definitely need to supplement your food intake of Vitamin D3 to make up for those factors that prevent you from getting your intake naturally.

Also, if you take a cholesterol-lowering drug, you are unable to produce natural Vitamin D in your skin, even though you might spend several hours in the sunshine.

Finally, if you spend one half hour in the sunshine without sunscreen or being hindered by drugs, your body will produce about 5000 IU of Vitamin D naturally.  For that reason, it is ridiculous to warn that that amount is too much.

The blood levels of Vitamin D range from 0-100.  The doctors I trust most recommend a blood level of at least 50.  After taking 5000 IU per day for over a year, my reading is 51, and I am grateful to God for unusually good health.
