Ask HN: Are Adaptogens Real or Bullshit?

Interestingly in this case the german entry has a bit more info

https://de.wikipedia.org/wiki/Adaptogen

If it is to be trusted is another matter. As with anything, there is hype, BS, marketing involved.

One could also ask if energy drinks are real or BS, apart from sugar and caffeine. Or so called 'superfruits'.
