Vitamin and supplement recommendations

[Italiancitizenship]

Hi - just looking for suggestions or what might have worked for you - my symptoms are knee pain (one knee), general stiffness after waking up or sitting for a while, always tired, finding it difficult to sleep more than about 5 hours, a general sense of feeling flat - what could I take that would help?

(I’m early 50s and don’t want to take HRT)

Thanks 😊
