Collagen Supplements - Capsules vs Powder

I'm curious of there's a difference between taking collagen supplements (especially type II) as a powder versus a capsule. Is there any science as to why one method of intake is preferred over the other?

Answer

Just get enough protein and don’t worry about collagen supplementation. Not a lot of evidence to support its benefits.

At this time, non-industry funded research on collagen supplements is lacking.

“While some studies have shown benefits from supplementation with collagen or gelatin in areas of osteoarthritis and aging skin, the evidence is fairly weak, as many of the studies are small,” she says. “Many claims to support the use of collagen products have yet to be substantiated. When you dig into published research regarding collagen’s effects on joint pain, the evidence doesn’t support the claims or theories at this point.”
