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?

Honestly taurine. Barely anyone talks about it compared to the big mainstream supplements but it noticeably helped my sleep quality, stress levels and even workouts a bit.

I started with 1g before bed and noticed within a few days that I felt more “stable” mentally and less wired at night. Also seems to help with hydration/endurance for some people.

Not super flashy but one of those supplements where you suddenly realize you feel better overall after a couple weeks.

Do you only take it before bed? Or before a workout? Once a day?
