I love supplementing with collagen powder - it's a great way to get in quality protein (only missing one amino acid) that supports joints, ligaments, hair, skin & nails!

Collagen can also be a great option if you struggle to get in protein due to supplements causing GI distress - collagen tends to be very beneficial to the gut. 

Can be found in bovine or marine varieties. I love Vital Proteins or Orgain brands. 

Vital Proteins brand can be found at Costco at a great price!
