Trumarine Collagen 100% ultra-pure collagen (premium select grade TruMarine™ Collagen) is sourced from exclusive sustainable, wild fish found in the deep, pristine waters of the South Pacific Ocean – north of Australia and approximately 5,000 km from the coast of Japan. The ocean currents of the Southern Hemisphere are separated by the Equatorial Counter Current and are completely different from those of the North Pacific. The Kuroshio Current of Japan flows north towards North America (not south) and therefore does not impact our product. withinUs TruMarine™ Collagen is not formulated with any other ingredients, preservatives or stabilizers.
