Evaluating products.

How do I choose a collagen product — and what does an honest one carry on its label?

Shelf order follows the evidence: the category leader (Vital Proteins) provides the trial-relevant 20g dose from bovine Type I & III in a well-recognized, flavorless format. The value option (Sports Research) matches the dose at significantly better cost per serving with third-party manufacturing. The marine option (Further Food) serves those who prefer fish-derived sourcing — noting the lower per-scoop dose and higher cost per gram. All three require the patience of a 12–24 week trial before judging results. The products below are educational examples — not medical recommendations.
