Hello Doctor, My Question Is Regarding Tendons. My Partner And

Hello Doctor,
My question is regarding tendons. My partner and I are gym fanatics and as we age we would like to begin taking supplements for both lubricating joints and something for tendons. We are aware of many supplements for the joints, but can you please advise a supplement that will help in the elasticity and suppleness of the tendons for future?
Thank you very much for your time.

Kindest Regards,
