Overview
An 8 fl oz bottle of berry-flavored liquid collagen combined with biotin, covering Type 1 and Type 3 collagen. It's aimed at people who prefer a liquid supplement over capsules or powder for daily collagen intake.
Liquid collagen supplements are typically chosen by people who find capsules or mixing powders inconvenient; this one comes pre-flavored in berry rather than unflavored, so it can be taken directly rather than blended into a drink. Pairing biotin with collagen is a common combination in beauty-focused supplements, since both are associated with hair, skin and nail support.
- 8 fl oz liquid collagen
- Type 1 and Type 3 collagen
- Includes biotin
- Berry flavor, non-GMO
Who it's for
Works for adults who want a ready-to-drink liquid collagen and don't mind a berry flavor. Not the right pick for anyone who wants an unflavored or powdered collagen to mix into other drinks or foods.
