If it is helpful, provide the study showing it! It’s too easy to say “look it up yourself” IMO.

Health “in general” is, health. What do you think health means?

The phrase that starts with:

Believing…

is just incompréhensible for me, I’m not a native speaker.

Yes longevity has become a serious research field, almost solely by the massive effort of Dr Aubrey de Grey. Read his 2007 book Ending Aging for a dumbed down explanation of what is needed to cure aging (as in a science interesed person can get it).

For third-party examination of supplements, that only shows what is in the pills, not that they are actually effective.

So again, stay away from any supplements until there has been some real studies done. There is always a supplement, once it was cinnamon, once it was radium water, always it was snake oil.

You want to live longer in good health?

What’s proven effective: don’t smoke, don’t drink(or very little), don’t be sedentary, don’t be overweight.

That’s about it as far as the scientific consensus has it.
