Sustainability Score

62%

While SupplementFirst shows commitment to sustainable packaging and carbon-neutral shipping, they lack transparency in their supply chain practices. Their private label products use some eco-friendly ingredients, but documentation about labor conditions and sourcing is limited. They have basic animal welfare policies but could improve their verification processes. Their environmental initiatives are promising but need more concrete targets and third-party verification.
