I am glad coming across this thread. Science is indeed not an instinctive studies but an extinction. Would you really want to have yourself an examplery practical case study with your motive @ OP? Oh wow it is so weird but that what it really called for when you want to get on a such research.
Maybe I should also bring to you about mr Bryan Johnson who is at his 45 yet a California based tech mogul that spoke with Steven Bartlett on the Diary of a CEO Podcast previously?
Oh yes of course I have a related lifestyle for you from this dude. He aimed to live forever to atleast get to witness the end of the 21st century with the goal to live forever.
He has already made his stipulated his task schedules  on a complex daily routine pertaining  the period of time and how long he sleeps, his eating lifestyle routines, sex lifestyle routines and more of it and he believes he is going to make it.

This is really quite baffling how people thinks and how extensively they could explore to transformations and the combinational creativities research and practices.
I am not a researcher on this field but I literally sometimes feels most supplements we consumes always has to work along with our mental believe so it could function or performs on an exact reason why it was taken. Sometimes I feel it is spiritual. If you don't believe it would work it wouldn't work but if you believe it will work then it works for you.
Do you ever believe you can have an intake pills for a Palliative but only to notice it worked for your curative or preventative cures and or vice versa?
So at some points of time believe we sometimes don't  get what we expected or general have no knowledgable ideals on what we takes in just as Tou said @ OP.
