DY Nutrition (Dorian Yates Nutrition) is a sports nutrition company developed in collaboration with bodybuilding legend Dorian Yates, a six-time consecutive Mr. Olympia champion. The brand's philosophy draws on Yates' extensive experience in professional bodybuilding and his distinctive high-intensity training approach, with the aim of developing nutritional supplements to support fitness, performance, and overall wellness.

DY Nutrition places strong emphasis on a science-focused approach to formulation. According to the company, ingredients used in its formulas are selected with reference to available research and the expertise of scientists and nutrition professionals. Its supplements also undergo laboratory and third-party testing to help verify the quality and integrity of both raw materials and finished products.

An important part of the brand's modern development is its partnership with Vitema Pharmaceuticals. Their joint investment included the establishment of a research and development centre in Sibiu, Romania, while manufacturing takes place in facilities operating according to pharmaceutical GMP standards, alongside ISO 9001:2015 and ISO 22000:2018 certifications. Quality procedures include physicochemical and microbiological testing of raw materials, intermediates, and finished products.

The DY Nutrition portfolio covers a broad range of sports nutrition products, including protein supplements, pre-workout formulas, creatine, amino acids, mass gainers, glutamine, recovery products, vitamins, and minerals, with options designed for different training and wellness goals.

By combining the experience and philosophy of Dorian Yates with science-focused product development and modern manufacturing and quality-control standards, DY Nutrition has established a comprehensive supplement range with a strong identity within bodybuilding and sports nutrition.
