My Collagen Routine: When I have back-to-back workouts, I often get my nutrition via liquid, as this is easiest for me to digest. I rely on smoothies — I'm a smoothie queen — and add Vital Performance™ Protein for a boost of protein on-the-go. I also put Vital Proteins® Collagen Peptides in my coffee and utilize Vital Performance™ RECOVER after long workouts.
