Assessing Collagen Potency

Used for joint, skin, and connective tissue support, collagen supplements vary widely in source and purity. 

Differences in amino acid profile, heavy metal load, and peptide degradation may influence both efficacy and safety; especially in older adults and those with dietary restrictions. 

Collagen supplements, especially marine-derived, may contain unsafe levels of heavy metals such as arsenic or mercury, depending on sourcing and processing. (Kržišnik 2024)
