MINERVA Research Labs uses hydrolysed marine collagen in all of our products with the exception of VEGAN, (plant based collagen) and ARTRON (which is Bovine and best for joints). Our hydorlysed marine collagen is extracted from fish skin (Tilapia fish); no other animal sources of collagen are used. All fish used to extract the collagen come from fish farms registered by the European Union for the import of edible fish and are deemed fit for human consumption and guaranteed by health certificates signed by official veterinarians.
