Choosing Quality Collagen Supplements: What to Look For

At Protea Nutrition, we believe informed choices are the foundation of better health. Collagen supplements have grown in popularity as more people look to support skin health, joint comfort, and overall wellness from the inside out.

Collagen is the most abundant protein in the human body and plays a critical role in the structure of skin, bones, tendons, and connective tissue. As we age, our natural collagen production declines, which is why many people turn to supplementation as part of a proactive wellness routine. According to the Cleveland Clinic, collagen loss is a normal part of aging and can impact skin elasticity and joint health over time.

One of the most important things we encourage customers to look for when choosing a collagen supplement is how the collagen is processed. High-quality products use hydrolyzed collagen, also known as collagen peptides. This means the collagen has been broken down into smaller amino-acid chains that are easier for the body to digest and absorb. This is why we formulated Collagen5+ using hydrolyzed collagen, intact collagen proteins are too large to be efficiently absorbed without this process.

Another key factor is the types of collagen included. While there are more than 20 types of collagen in the body, Types I, II, III, IV, and V are especially important for supporting skin, joints, connective tissue, and overall structural health. Many supplements on the market contain only one or two types, usually Types I and III. Collagen5+ was designed differently, it delivers five types of collagen (I–V) in one formula to provide broader, more comprehensive support for multiple wellness goals.

Ingredient transparency is another standard we take seriously. We believe a quality supplement should be easy to understand, free from unnecessary fillers, and clearly labeled. When evaluating collagen products, it’s also helpful to look for brands that prioritize purity and responsible sourcing. Third-party testing organizations like USP, NSF International, and GMP certification, etc. help verify that supplements contain what they claim and are free from harmful contaminants.

Finally, it’s important to remember that supplements work best when they fit your individual lifestyle and health goals. Research suggests hydrolyzed collagen may support skin hydration and elasticity and help maintain joint comfort in some individuals, though results can vary and ongoing research continues to refine best practices. We designed Collagen5+ to be easy to mix into coffee, smoothies, or recipes so it can seamlessly support a balanced diet and healthy routine. As always, we recommend consulting a healthcare professional before starting any new supplement.
