Compliance is non-negotiable in the health supplement industry. For the US market, ensure the supplier is FDA Registered and follows cGMP (current Good Manufacturing Practices). For the EU, products must comply with Novel Food Regulations and REACH. If you are marketing the product as organic, verify USDA Organic or EU Organic certifications. Additionally, always request a Heavy Metals Analysis to ensure lead, arsenic, and mercury levels are well below safety thresholds (e.g., USP <2232> standards).
