Supplement comparison results

Primary ingredients How we evaluate

We verify collagen content (mg) per intake and molecular size (Daltons), evaluating intestinal absorption efficiency. Products with low-molecular collagen ≤500Da show faster absorption and high bioavailability, rated favorably. We assess 3,000-4,000mg+ sufficient content fulfillment and review raw material extraction method and origin, expression accuracy, and clinically-validated forms (peptides, tripeptides, etc.).

Price How we evaluate

We calculate per-gram price basis to evaluate ingredient cost-effectiveness. Beyond just unit price, we consider actual absorbable low-molecular collagen content, formulation efficiency, and combination components in practical value assessment. Whether mg-per-unit cost is reasonable for long-term consumption is an important criterion.

Brand How we evaluate

We confirm raw material origin and manufacturing process transparency, and highly evaluate GMP certification and health functional food labeling. We verify clinical/research data availability, production history management, and test report (CoA) disclosure. We particularly evaluate brands with comprehensive raw material supply chain management and product recall history review.

Quality How we evaluate

We comprehensively examine collagen molecular size, content, and stability, plus formulation quality and safety. We verify whether antioxidant components (vitamin C, polyphenols, etc.) are included and examine storage stability, individual packaging, and oxidation/deterioration prevention during long storage. We also verify unnecessary additive minimization and product form consumption convenience.

Additional ingredients How we evaluate

We focus on collagen synthesis and skin elasticity-supporting components (elastin, hyaluronic acid, vitamin C, biotin, etc.) inclusion. We particularly examine hyaluronic acid ≥120mg and elastin ≥75mg effective-level combinations. We verify unneeded additive minimization and clear raw material source/content labeling.
