There is lots of talk about heavy metals in plant-based proteins, and we get the concern. But not everything online tells the full picture.

Let’s clear things up: some claims are overhyped. At Macro Mike, we rigorously test our products to make sure they are clean, safe, and held to the highest standards, always!

I heard all plant proteins have heavy metals. Is that true?

Here’s the deal: all plants naturally absorb trace elements from the soil they grow in. That includes nutrients like iron and magnesium, but also tiny amounts of heavy metals like lead or cadmium. This happens even in organic farming. So yes, small traces can show up in plant-based ingredients like rice, legumes, or nuts.

The levels are extremely low, and well within the safe limits set by global food safety authorities. It’s not unique to plant protein; it’s just nature doing its thing.

Should I be worried about this?

No, not when it’s handled properly.

What really matters is how we manage and monitor these trace elements. At Macro Mike, we don’t just meet the standards set by FSANZ (Food Standards Australia New Zealand), we go above and beyond.

You’re more likely to find higher levels of heavy metals in everyday foods like spinach, dark chocolate or rice than in a serve of our protein powder.

Do you test for heavy metals at Macro Mike?

Absolutely.

We test all our raw ingredients and finished products through trusted third-party labs. Our suppliers also provide full Certificates of Analysis with each batch to confirm they meet our strict quality standards.

We’re obsessive about this stuff because we use our own products too. If it’s not good enough for us, it’s not good enough for you.

So, why do some online reports make it sound so scary?

A lot of the fear comes from lack of context.

Some reports highlight that a plant protein contains heavy metals but skip the part where the levels are far below any harmful threshold. It’s a bit like saying yogurt has bacteria, technically true, but it’s the good kind, and totally safe.

Without context, it sounds scary. But with full transparency, it makes total sense.

Is plant protein riskier than whey?

Not at all.

Both whey and plant proteins can contain trace amounts of heavy metals depending on where they’re sourced and how they’re processed. The real difference lies in quality control and testing practices, and that’s where Macro Mike shines.

We carefully source every ingredient and rigorously test every product, so you can feel confident in every scoop.

Is it safe to have Macro Mike protein every day?

Yes, 100%.
