When we asked collagen companies for safety documentation, most—including big names like Vital Proteins, Great Lakes Wellness, and Nordic Naturals—refused or stayed silent.

Since collagen is sourced from animal tissue where toxins can build up, this lack of transparency is concerning.

Premium prices or “grass-fed” claims don’t guarantee safety. A few brands did provide full test results, proving transparency is possible. For a supplement taken daily, safety documentation should be the rule, not the exception.
