What makes it different
Most fish fertilisers are heat-treated emulsions that destroy the natural oils and proteins in the process. The Protein Shake is made from 100% Australian tuna by-product using a cold-press enzyme digestion process — no heat, no water added. This preserves the full protein and oil profile, making it the purest fish product available and more effective than standard fish emulsions.

Why it works
The proteins and oils in fish hydrolysate act as natural chelating agents — making nutrients immediately available to plant roots while simultaneously feeding soil bacteria and fungi. It's not just feeding your plants, it's feeding the entire soil food web that makes your garden function. River and groundwater safe, certified organic.

Ingredients
100% Australian tuna by-product — cold-pressed fish hydrolysate, no water added, no synthetic additives.

Best paired with
These three form our Starter Kit — the foundation of a healthy garden.
