Collagen After 40: Which Supplements Actually Work (and Which Are a Waste)

Dr. Sarah MitchellFeb 10, 20266 min read

Collagen production falls 1%/year post-25, accelerating in menopause (30% loss first 5 years). Supplements: hydrolyzed peptides absorb best.

Evidence Breakdown

Improves elasticity 10-20% (8-12 weeks, multiple RCTs)

Hydration +1.5% wrinkle depth reduction

Marine: finer particle for skin focus

Bovine: multi-collagen (joints too)

Gummies (<2.5g ineffective)

Collagen coffee/creamer (denatured by heat)

Plant "collagen builders" (no actual collagen)

Must-Haves: +Vit C (proline/hydroxyproline synthesis)

Vital Proteins (bovine, 20g/scoop)

Sports Research Marine (10g)

Dose & Co (unflavored peptides)

Track skin via photos/app. Results visible 8 weeks.

A: Amino blend (glycine/proline) approximates; less evidence.

A: Too large to penetrate.

Invest in peptides, not promises.
