NoordCode Pure Collagen is sourced from European grass-fed cows. The cows eat grass throughout the year. They are not fed any hormones or antibiotics so the end product is as high-quality as it can be. NoordCode uses a new processing method to further improve the quality of collagen hydrolysate. The new method produces a finer collagen powder with an even more neutral taste. This makes the collagen powder more pleasant to consume and more absorbable in the body. The purity has been tested in an independent laboratory. Pure Collagen is halal-certified.
