Why this tier: Best-represented form across skin, joint and muscle RCTs; multiple independent double-blind placebo-controlled trials at 2.5-10g/day show measurable outcomes. Generic "Collagen"/"Total Collagen" label entries (no processing specified) default here as the most common commercial form, flagged for manual review rather than assumed with full certainty.
