Vital Proteins Collagen Peptides Powder ($43, originally $51)

This bestselling collagen-infused peptides powder has a fan in Jennifer Aniston, who adds it to her morning cup of coffee. It promises to support collagen production, which leads to smooth skin as well as hair and nail growth. Our editor raved about the product in her Vital Proteins Collagen Peptides Powder review.

Editor Quote: "I love the collagen powder for its ability to add a hearty dose of protein to anything I'm eating or drinking — it transforms a black coffee or low-protein veggie soup into something that's more satiating and protein-packed." — Christina Stiehl, former senior fitness editor
