Collagen After 30: What Actually Works

By age 30, most women have already lost a significant percentage of their natural collagen production. The result: fine lines appear, skin loses its bounce, and hair starts thinning at the temples. But does supplementing actually help?

What the Research Shows

Multiple randomized controlled trials have found that hydrolyzed collagen peptides can improve skin elasticity, hydration, and dermal collagen density when taken consistently for 8-12 weeks. The key word is hydrolyzed — meaning the collagen is broken down into smaller peptides that your body can actually absorb.

Marine vs. Bovine: Which Is Better?

Marine collagen (from fish) is primarily Type I collagen, which is the most abundant type in human skin. It also has smaller peptide molecules, which may mean better absorption. Bovine collagen contains both Type I and Type III, which supports skin and joints.

The Vitamin C Connection

Your body needs vitamin C to synthesize collagen. Taking collagen without adequate vitamin C is like buying building materials without hiring a contractor. Look for collagen supplements that include vitamin C, or pair your collagen with citrus fruits.
