Our collagen is tested by Eurofins UK, one of the world’s most trusted labs, and the results are exceptional. With lead and mercury levels so low they’re barely detectable (<0.005 mg/kg), cadmium at just 0.005 mg/kg, and arsenic at a tiny 0.024 mg/kg, these figures are dramatically beneath international safety standards. This means our collagen is not only safe for everyday use — it’s remarkably pure, providing peace of mind alongside powerful benefits for your skin, gut, and joints.
