Sustainability Score

62%

While Optimum Nutrition has made some progress in sustainable packaging initiatives and responsible sourcing, their transparency regarding environmental practices and supply chain management needs improvement. Their parent company Glanbia has better documented sustainability commitments, but ON-specific initiatives are limited. Animal welfare standards meet basic requirements but aren't industry-leading. Their manufacturing facilities have achieved some energy efficiency improvements, though comprehensive environmental impact data isn't publicly available.
