WHY STAINLESS STEEL

Plastic shaker bottles release microplastics with regular use.

A 2026 study of reusable plastic shaker bottles found measurable microplastic release during routine shaking. Stainless-steel mixing balls increased release through abrasion against the plastic bottle. A stainless-steel bottle avoids that particular plastic-wall abrasion pathway; final shaker components still need sample testing.

Source: Polymer-specific abrasion and aging govern microplastic release from reusable plastic shaker bottles, 2026.

Read the research: plastic vs stainless-steel shakers. Particle release does not establish harm from ordinary shaker use.
