More D ping.
does anyone know the difference of the types of D on the market to take for supplementation? I often see different types and don’t really know if I am taking the best one.
What’s the definition of a “high level?”
How much is a “high” level?

High vitamin D level = high testosterone level
There’s an amazingly simple way for western men to raise their testosterone level. All they have to do is take a supplement containing extra vitamin D. At least, this is what we deduce from an epidemiological study done at the Medical University Graz in Austria, which will soon be published in Clinical Endocrinology.
Vitamin D is actually a hormone – one that regulates three percent of our genes. Among those genes are a few that are responsible for the production of testosterone in the Leydig cells. So vitamin D is an important vitamin, certainly once you realise that an overwhelming majority of the western population has too little vitamin D in their blood.
This is because our food contains too little vitamin D, so we have to rely mainly on the vitamin D that our body makes. When exposed to sunlight our skin cells convert cholesterol into vitamin D. But we get too little sunlight and are therefore unable to make enough vitamin D.

—that’s what was being said about Vitamin E about 35 years ago—
I resemble that remark.
The only thing that bothers me about these studies is that correlation does not prove causation. What if diabetes causes low vitamin D levels, rather low levels of D being a contributing factor to the development of diabetes?
It’s like all those studies that say active people are healthier. What if it is really the case that healthier people feel better, and are more active?
The real test of these theories about vitamin D will come when it can be shown that D supplements actually improves a person’s health, and that will take many years of observation and study.
