Overview
Zena Nutrition's liquid collagen combines 2500 mg of Verisol bioactive collagen peptides with 5000 mcg of biotin in a berry flavored liquid rather than capsules or powder. The 20 fl oz bottle is rated for 60 servings and is gluten, dairy and wheat free.
Verisol is a specific branded collagen peptide rather than a generic hydrolyzed blend, and pairing it with a high dose of biotin points this squarely at hair, skin and nail claims listed on the label. Being already liquid removes the mixing step a powder collagen would require.
- 2500 mg Verisol collagen peptides
- 5000 mcg biotin per serving
- Mixed berry liquid, 20 fl oz
- Gluten, dairy and wheat free
Who it's for
Aimed at women wanting a premeasured collagen and biotin drink rather than a powder to stir into water, and anyone avoiding gluten, dairy or wheat. Not for those sensitive to high dose biotin or wanting an unflavored option.
Strengths and trade-offs
Drawn from this product's published specifications.
- Ready to drink, no mixing
- Uses branded Verisol collagen peptides
- High dose biotin included
- Gluten, dairy and wheat free
- Only mixed berry flavor offered
- 5000 mcg biotin exceeds typical daily needs
Performance notes
Because it's already liquid, there is no dissolving step the way powder collagen requires, and the Verisol branding signals a specific bioactive peptide formulation rather than a generic collagen blend. Sixty servings from 20 fl oz means each dose is roughly a third of an ounce.
