This podcast episode interviews Oliver Amdrup-Chamby, co-founder of Puori, about a study revealing heavy metal contamination in nearly half of US protein powders. The discussion covers how heavy metals enter the supply chain (soil contamination, organic vs. conventional), safer protein powder choices (pea protein is highlighted as a potentially better option than rice or other plant-based proteins), and the importance of transparency and testing. The conversation then shifts to fish oil, emphasizing the need for high-potency, pure products with low oxidation levels, and recommending checking IFOS certifications. Listeners learn about factors influencing fish oil quality (source, fishing location, processing) and practical tips for choosing and storing supplements. Ultimately, the episode aims to empower listeners to make informed choices when purchasing protein powders and fish oil supplements.
