Soy is everywhere — and not always in a good whey (idk just felt like using that spelling). If you’ve had enough of bloating, hormone concerns, or dodgy ingredients, this guide is for you.
Why Do People Avoid Soy?
Here’s the deal — soy is everywhere. It’s cheap, processed, and the default base for many so-called “plant-based” protein powders. But for plenty of Aussies, soy isn’t all it’s cracked up to be. Common concerns include:
- Allergies: Soy is one of the top 8 food allergens worldwide.
- Hormone Concerns: Soy contains phytoestrogens, plant compounds that mimic oestrogen in the body.
- Gut Upset: Many people report bloating, gas, or stomach discomfort after soy-based shakes.
- Environmental Impact: A huge portion of global soy production is linked to Amazon deforestation.

Why We Skipped the Soy (And Chose Lupins Instead)
✓ 100% Soy-Free: No trace soy. No cross-contamination. No worries.
✓ Gentle on the Gut: Patented Aussie refinement removes bloating triggers.
✓ No Phytoestrogens: No hormone interference — just clean, complete protein.
✓ FSANZ-Compliant: Transparent allergen labelling you can trust.
✓ Low-Impact Farming: WA-grown lupins that help regenerate soil, not destroy forests.
Who Should Consider Soy-Free Protein?
If any of these apply, a soy-free protein powder could be a game-changer:
- People with soy allergies or intolerances
- Anyone managing hormonal balance
- Those feeling bloating or sluggishness after soy-based shakes
- Health-conscious shoppers chasing cleaner, simpler labels
- Eco-aware Aussies who care about sustainability
