My wife and I use Double Wood Supplements' Collagen, here...
It does contain Collagen types 1, 2, and 3 - the only ones you really need to worry about supplementing. This product is just pure Collagen, so to fully unleash its effects you would want to supplement some cofactors alongside it. It comes from pasture-raised, grass-fed happy cows.
Evan at Double Wood responded to a question on Amazon...
This combination of collagen types contains 19 different amino acids and is especially rich in hydroxyproline, glycine, and proline. It is one of the few protein sources which contains high levels of hydroxyproline, but is missing tryptophan so it doesn't have the full essential amino acid profile you'd get from meat or dairy.
