Hi, had a question I thought some RDs could weigh in on.
I've seen a lot of supplements recently with collagen protein in them, some with gelatin, some with hydrolyzed collagen, and some with enzyme-predigested collagen.
Some have added amino acids to the predigested collagen - cysteine, histidine, methionine, threonine, tryptophan.
I'd heard for years that collagen was junk protein and not really of much biological value at all, but I know that PDCAAS is now not necessarily seen as foolproof and DIAAS is maybe going to supplant it, so maybe things have changed?
My question is whether hydrolyzed collagen, or enzyme-predigested collagen with aminos added to it, are effective proteins when it comes to a quick-absorption protein suitable for use in sports recovery, or recovery drinks, and so on.
And if not, what are better proteins for the purpose i.e. you're in a race and eating on the go and need something that will digest and absorb well.
Lots of misinformation so I'm trying to educate myself but there is a lot of confusing/conflicting info out there from the product mfrs.
Any help appreciated. Thanks.
