Marnys Natural Quality



At MARNYS® we have been working day after day for 50 years, being faithful to the principles of quality, control, security and innovation, in order to offer our customers the highest quality in all our manufacturing processes and in the final product.

We have been able to position ourselves in the sector as one of the suppliers with the highest quality in natural products. We believe that these are healthier and more effective than synthetics.

Our insistence on natural factors is one of the great values that makes us stand out from the rest of the nutrition and natural beauty market where the use of synthetic products is uncontrollable.




Irradiating ingredients is a manufacturing method that uses levels of ion radiation to prevent deterioration and potential pathogens. This process irreparably damages DNA and cell membranes, and also breaks the enzymatic pathways. This is why MARNYS® does not use this type of ingredients.




GMO ingredients are genetically modified ingredients. This method uses gene splicing to create products with non-natural attributes, such as rapid growth or resistance to plagues and fungal growths. As this is not a natural method, MARNYS® avoids the use of GMO ingredients.
