Nearly half of the top selling protein powders tested in a recent Clean Label Project investigation exceeded California Proposition 65 safety thresholds for lead. Even more concerning, 21 percent contained more than double the acceptable limit.
For an industry built on health, performance, and recovery, that’s a difficult statistic to ignore.
It’s also one reason supplement transparency has become a growing conversation among athletes, coaches, and health conscious consumers. Protein content, amino acid profiles, and ingredient lists still matter, but more people are beginning to ask what else might be coming along for the ride.
Oliver Amdrup Chamby, CEO and co founder of Puori, believes consumers deserve more than marketing claims.
“At Puori, we worry about what’s in our supplements, so you don’t have to,” he says.
That philosophy came from personal frustration. More than fifteen years ago, Chamby and his co founder were searching for a fish oil supplement they could trust. During their research, they found that many manufacturers couldn’t provide basic information about freshness, oxidation levels, or heavy metal contamination.
“We realized that if we wanted a product that met our expectations for quality and transparency, we would have to create it ourselves,” Chamby says.
That experience eventually led to the creation of Puori, a supplement company built around third party testing and publicly available batch results. Today, the company says every batch is tested against more than 200 potential contaminants, including heavy metals, pesticides, PFAS, BPA compounds, oxidation markers, and other unwanted substances.
The broader lesson extends far beyond a single brand.
Athletes spend countless hours dialing in training programs, recovery routines, sleep habits, and nutrition strategies. Yet many never investigate the quality standards behind the supplements they take every day. If performance is the goal, purity matters just as much as dosage.
The conversation also reflects a larger cultural change within fitness. Consumers are becoming less interested in miracle solutions and more interested in accountability. Trust is increasingly being earned through evidence, testing, and transparency rather than branding alone.
For readers looking to make better decisions, the takeaway is straightforward.
Ask whether products are third party tested.
Look for publicly available batch results.
Research where ingredients come from.
Understand what standards a company follows before making it part of your daily routine.
Most people spend more time researching their next pair of running shoes than the supplements they consume every day. As wellness becomes more sophisticated, transparency may prove to be one of the most valuable ingredients on the label.
