[The reason these citations are included in the references files are because
they are referred to from previous changes to our supplement regimen pages:

I read an old news about Astaxanthin on internet saying
"Research is showing astaxanthin increases the life span of lab
animals 37%"
I wanted to learn whether its mean or maximum life span and
also on which animal species the experiment was done.
However, I couldn't find any reference for this.
