renew gold vs renew gold senior

I have had good luck with renew gold in the past and when I went to buy some for my new boy I noticed they now make renew gold senior. Does anyone have any experience with this one and any opinions? I’m trying to figure out if it is the same exact formula just with a couple extra ingredients, or if it is completely different.

The ingredients and analysis are on the website

Personally, I’d rather add my own joint supplement. At even the high end feeding rate of 2lb, the Sr still doesn’t contain nearly enough glucosamine or chondroitin sulfate.

Ya, I noticed that, but the cost is only 2 dollars a bag more I thought eh why not
