"Premium marine collagen at $2.17/serving"
Wholesale marine collagen costs ~$0.30–0.40 per 12g serving. Comparable products (Sports Research, Now Foods) cost $1.30–1.60/serving.
Consumer advice
If you want marine collagen specifically (pescatarian-friendly, Types I & III from fish), this is a legitimate product at a reasonable dose. However, shop around: Sports Research, Now Foods, and bulk suppliers offer nearly identical marine collagen peptides for 30–50% less. If you're not pescatarian, Vital Proteins' own bovine Collagen Peptides ($27 for 10oz) is cheaper and has the same evidence base. Take 10–12g daily consistently for at least 8 weeks before judging results — collagen benefits are slow and modest. Fish allergy? Avoid entirely.
