Improving Cellular Health and specifically Vitamin D

I have been doing quite a bit of self-experimentation with a view to improving my cellular health and trying to undo some of the damage that has been done to my cells over the years.   I don't necessarily want to describe that as age reversal, but there are clearly aspects that involve reversing some of the cellular damage that comes from the aging processes.

One aspect of this is working things out like how much Vitamin D to take and I have done a video about that which may interest people.
