Collagen: What It Can and Cannot Do

Collagen is one of the most popular supplements on the market — and one of the most misunderstood. Here’s an honest, evidence-informed look at what collagen can and cannot do.

What Collagen Actually Is

Collagen is the most abundant protein in the human body, making up skin, tendons, ligaments, cartilage, and bone. Production naturally declines with age — starting in your mid-20s and accelerating after menopause.

What the Research Supports

• Skin elasticity and hydration — multiple studies show improvements with 2.5–10g daily of hydrolyzed collagen
• Joint comfort support — type II collagen shows promise for joint wellness
• Connective tissue support — relevant for active women and those recovering from injury

What Collagen Cannot Do

Collagen supplements are not a complete protein source — they lack tryptophan. They will not reverse aging, replace a balanced diet, or substitute for medical treatment of any condition.
