Actually, for skin/hair/nail/joint support, the studies are pretty encouraging and the emerging science wholly supports collagen as a viable supplement. There is less data around collagen for muscle building/repair, but that's not my goal in taking it, so not a concern. I understand it's not a complete protein and therefore not a suitable sole source. Just wondering if, generally speaking, it should count towards overall protein goal. I don't want to short change myself, but also don't want to constantly be striving to hit a goal that I might already be achieving. Sent from my SM-A205U using BariatricPal mobile app
