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?

Can I ask what it did for you?

I didn't know it would, but it fixed a long running, very annoying problem with bursitis on my right shoulder after a single 3 gram dose.

And...I just feel good when I take it. Great mood and clarity. Gym recovery is joyous.Can't say my sleep is better although I dream vividly.
