[L-Tyrosine dosage?]

Hi everyone, I have no idea what all these supplements are. Could somebody please educate me? What is lions mane, tyrosine , and Yerba mate? Are these sold at whole foods or GMC or Walgreens and do they just start a whole other problem (addiction)? Looking forward to any and all advice . Thanks so much.
