Optimal levels of IGF-1

Good morning,

Browsing and searching this knowledge base and Rosedale's book and articles, I cannot find an actual practical recommendation for the optimal levels of IGF-1 in the blood. Obviously there has to be some, and the level is not going to go to zero. But, I, and I'm sure many other people, would like to know what is the optimal for circulating IGF-1, just like we know that for insulin is it < 5, but clearly above 1.

In addition, it would be really great to have a table of Dr Rosedale's ideal levels for the most important blood markers that are (or should be) tested on a yearly or bi-yearly basis. A reference table for blood marker values.

Thanks in advance for your help.

    Thanks. I signed up to get email updates. But can't you just give us a quick answer for an optimal value/range for IGF-1?

    Guillaume, there may be variables that need to be explained by Dr. Rosedale and a quick answer would not be the wisest way to approach this. You will have to wait and see.
