Collagen seems to be a latest craze for human supplement. Has anyone here fed it to horses or done the research to see if it is beneficial and if so, what form?
I agree, as with alot of the trendy supplements there is usually not much evidence and especially with feed through it being absorbed to be beneficial is limited.The question with anything like that is 1) is it easily absorbed as is? and 2) is it broken down further in digestion, and those components easily absorbed? It's pretty safe to assume that a lot of things we try to feed our horses have to be fed in excess (possibly dangerous excess) before they're even absorbed, and then able to reach their destination to have an intended effect. That's one reason that injections are more popular for arthritis - it puts the supplement straight into the bloodstream and "out for delivery," or straight into the joint.
