Quick answer: Collagen supplements are protein-based products that support skin, joints, and connective tissues. In New Zealand, they are commonly taken as powders or capsules. While some people notice improvements in skin hydration and joint comfort over time, results vary and consistency matters.

What are collagen supplements?

Collagen supplements are dietary products that provide amino acids used by the body to support collagen production. Collagen is a key structural protein found in skin, joints, bones, and connective tissue.

Most supplements are derived from bovine or marine sources and come in forms such as powders, capsules, and tablets.

For example, options like collagen infusion capsules or raw collagen powder offer different ways to include collagen in your daily routine.

What are the benefits of collagen supplements?

Skin support

Collagen plays a role in skin elasticity and hydration. Some people report smoother or more hydrated skin after consistent use.

Joint and mobility support

Collagen provides structural support to cartilage. Supplementing may help support joint comfort, especially for active individuals.

Hair and nail strength

Collagen contains amino acids that contribute to keratin production, which supports stronger hair and nails.

General wellness support

As a protein source, collagen contributes to overall nutritional intake and may support recovery and tissue repair.

Do collagen supplements actually work?

Research suggests collagen peptides may support skin elasticity and joint health in some individuals. However, results depend on factors like diet, age, and consistency of use.

We recommend viewing collagen as part of a broader wellness approach rather than a standalone solution.
