Vitamin D is a vitamin we can get for free. It comes from the natural UVB rays of the sun and when people get enough vitamin D it can protect the body’s immune system and prevent ill health.


Most of the United States population, however, is vitamin D deficient.

John, that's very true ... it's been widely discussed in the alternative media for a good long while ... mainstream media is just now catching up.

An interesting aside to this is a study done by a Swedish team of researchers who have charted increases in skin cancer that coincides with the increases in sun screen usage. The sun screen seems to block the natural production of vitamin D (the cancer preventative), while the absorption of the UVA rays by the chemical components (same components that are used in the lab to culture cancer cells) penetrate deeper into the layers of the skin than these UV rays would otherwise be capable of, and remain there long after one has come in from the sun.

There these chemicals sit with accumulated UV, irradiating adjacent healthy cells for hours after sun exposure ceases.

One extra note, the amount of vitamin D needed differs greatly based on latitude, skin color and season. I can't seem to find this website anymore, but I calculated how much sun exposure I would need and it was something like 8-10 hours a day. Clearly that is impossible, so I absolutely need to supplement. That 15 minutes a day estimate is not accurate or one size fits all.

My Vit D tank got empty after I came in from the sunbathing I did for many years. I had read somewhere that one could get 20K vit D on the beach in bathing suit for like 6-8 hrs. I did that many hours a lot in my life before my early 50's hit. Then I did come in from the Sun and didn't have a clue what I was doing re: Vit D needs. I was feeling a lowness in 2006 and put it all together with the help of my sister who dealt with MS and talked the Vit D and MS patients.

Depends! I am sure you can get plenty if you have lighter skin. People with more melanin absorb the Vitamin D way more slowly!

If you don't have enough cholesterol or sulfate in your skin, you'll never make enough vitamin D. You also need, Vitamin K2 and Vitamin A to activate the Vitamin D-produced proteins with calcium. If you have a chronic infection, then you will spend a lot of Vitamin D fighting it.
