FITNESS AUTHORITY® Sp. z o.o. has been one of the largest manufacturers of dietary supplements and sports nutrition products in Poland since 2004.

Our brand was created on the basis of many years of experience in the supplement and fitness industry - since 2004 it has been a trendsetter on the Polish market. Two years after we commenced operations, we launched our own brand of nutritional supplements. For eight years we have been publishing the Muscular Development magazine, which has grown a readership of hundreds of thousands countrywide. Being a pioneer in the field of bodybuilding competitions in Poland, we have become a leader in the industry, inviting famous athletes from all over the world. In the years that followed, we steadily expanded our product range and conquered new foreign markets to export products to more than 80 countries worldwide by 2022.

and safety

At FITNESS AUTHORITY® we constantly evaluate the market demands. Launching of any new product begins with the concept. We put quality first, which is why each sample is evaluated by our team - every aspect must comply with the required standards for the product to be approved for production. Subsequently, each manufactured batch undergoes laboratory testing. The final stage of a product launch are tests by the athletes, as it is their opinions that are of key importance to us. When manufacturing our products, we use only high-quality, certified raw ingredients to meet our customers' expectations. All the supplements in our product range are laboratory tested and evaluated. We constantly monitor the market and its needs, which is why we not only create new products but also improve those that have been already launched.

Quality proven by certificates

We are committed to the very best quality and only use tried and tested ingredients. ISOQAR CEE Sp. z o.o. and InterCert Sp. z o.o. certificates confirm that FITNESS AUTHORITY® complies with the ISO 22000 standard for the development of label and packaging designs, production and packaging of powdered foodstuffs into plastic and laminate packaging. In addition to our commitment to product quality, we are constantly raising the awareness and qualifications of our employees. We meet all the necessary legal requirements and continuously improve our Quality Control System.
