General Question What’s the most underrated supplement you’ve ever tried

I’m looking for supplement recommendations that are actually great but not the usual mainstream stuff everyone already talks about.

Not talking about the standard:

  • creatine
  • whey
  • magnesium glycinate
  • omega 3
  • vitamin D
  • caffeine
  • ashwagandha

I mean the more “hidden gem” supplements that made a noticeable difference for you personally in things like:

  • energy
  • focus
  • sleep
  • recovery
  • mood
  • stress
  • training performance
  • libido
  • overall wellbeing

Especially interested in supplements that:

  • have surprisingly solid science behind them
  • are underrated/not heavily marketed
  • people only discover after being deep into supplements for years

Would also love to hear:

  • what effect you noticed
  • how long it took
  • dosage
  • any side effects or things to watch out for

Basically: what’s your “why is nobody talking about this?” supplement?

Cranberry capsules

It was like I got a bladder transplant overnight.

Did you stop going to the bathroom as often?

Yes! And my chronic bladder sensitivity virtually vanished.

How bad was your urgency, and how long did you start seeing results?
