Anyone Tried Tryptophan? Did It Boost Your REM & Deep Sleep?

Hey everyone, I’m curious if anyone here has experimented with tryptophan (the amino acid) and noticed changes in their REM or deep sleep metrics? Asking here specifically because with Oura ring or similar, we can see these trends so clearly.

If you’ve tried it, did it help, or not so much? Dosage and timing tips are welcome too. Thanks! 🙌
