Are there heavy metals in plant protein? Here’s how we keep ours clean
Are there heavy metals in plant protein? Here’s how we keep ours clean

There has been growing attention on heavy metal contamination in protein powders, particularly plant-based varieties. Independent reviews overseas have shown that some brands exceed recommended limits for lead and other metals, providing a reminder of why testing and transparency matter.

At Matakana Superfoods, we take a more rigorous approach. 

✔ Regular heavy metal screening
Every batch is tested using ICP-MS, a highly sensitive method that screens for arsenic, cadmium, lead and mercury. The results consistently meet, and typically exceed, recognised FSANZ and EU safety standards.

✔ Clean, solvent-free processing
Our plant proteins are produced using a clean aqueous extraction process, without chemical solvents or harsh enzymes. This preserves amino acid integrity while helping remove residual minerals and anti-nutritional factors.

✔ Responsible growing regions
We source from Australian pulse-growing regions known for lower baseline heavy metal levels compared with many global farms, an added safeguard before processing even begins.
