Funny you mention it, my PT does chiro and massage as well

. Those seem to be the best, the ones that dont just rely on one aspect.
Your one of the few who actually listed to my prolo preaching, most just ignored me but the shit works wonders. I know my prolo doc has some supps he recommends but they were spendy and I think missed the boat on the importance of vit C and lysine.
If one were to take vit C to bowel tolerance along with lysine chondroitin while getting prolo it would work so much faster and collagen produced would be significantly stronger. Woth I had known about that myself back when I was getting a lot of prolo done. Luckily, knock on wood, I havent needed prolo in a couple years, which I contribute to my laundry list of supplements.
