First, has the dog had a senior workup? Exam and lab work. If not, I would start there.
Supplements are not medication. I would find a veterinarian that you trust and that your dog likes, and go by his recommendations.

“The internet is no substitute for talking with a vet who knows you and your pets about their specific needs.” copied from a response to a question: http://skeptvet.com/Blog/2016/07/things-holistic-vets-say-about-cancer-that-should-make-pet-owners-run-the-other-way/comment-page-1/#comment-119501

PS: It doesn’t hurt to go with a higher quality food, however, some of the better foods are higher in calories, so, if you have a senior inactive dog, that is something to keep in mind.
