"Zmiany Zmiany" is a manufacturer of natural, gluten-free and vegan bars. The products contain no sugar, syrup, preservatives or any flavor enhancers. You can find protein, energy and fruit bars. The production uses only ingredients of plant origin, such as: nuts, fruits, seeds or seeds mainly from Africa and South America. The products are not organic certified. The producers indicate that they are researching the replacement of plastic packaging with biodegradable packaging, but due to the nature of the product (the bars are highly fatty) the work will take time. In addition to producing the bars, "Zmiany Zmiany" is involved in a number of campaigns and sporting events supporting a healthy lifestyle. They donate part of their profits to the "Stowarzyszenie Otwarte Klatki" and support Foundations for children with brain palsy. They also donate the bars to charity auctions for children and animals.
