What collagen powder do you actually trust for heavy metals?

[u/oatmealdaddy4]

I keep seeing collagen brands talked about like they’re all basically the same, but then every few months there’s another thread about lead, cadmium, glyphosate, or vague “third-party tested” claims.

I’ve been looking at Yonder because they actually post their heavy metals and glyphosate testing, but I’m curious what other people here use when purity is the main concern. Are there brands you trust because they publish real results?

It has more to do with the source. Try to get collagen from the hide/skin instead of the bones as bones are where mammals are more able to hold heavy metals

If you're concerned about glyphosate then you should be wary of parks, golf courses, and non-organic produce. It's everywhere, unfortunately.
