Micronutrients & recovery
Hydrolysis of dairy proteins increases amino acid bioavailability and peak concentration compared to non-hydrolyzed forms, whereas hydrolysis of collagen proteins does not significantly alter bioavailability compared to non-hydrolyzed forms.
You do not necessarily need expensive hydrolyzed collagen peptides. This study found that standard gelatin (non-hydrolyzed) provided similar amino acid bioavailability to hydrolyzed collagen. However, for dairy proteins, hydrolyzed versions do absorb faster and reach higher peaks. If you are using dairy protein for post-workout recovery, hydrolyzed might be slightly better, but for collagen, standard gelatin is a cost-effective alternative.
Although there were several differences in the bioavailability of hydrolysed compared to non-hydrolysed proteins, this only reached statistical significance within the dairy proteins, but not for collagen proteins.
Why this rating
Clear statistical distinction between dairy and collagen processing effects.
