A note from Tom Digby

I’ve spent years in high-performance environments where constant attention goes into small details that make a real difference. One of the biggest is what you put into your body.


But I quickly realised a lot of what athletes, and everyday performers, consume is loaded with artificial ingredients and unnecessary sugar. And yes, sugar has its place in sport, just not all the time.

And when I dug into the research, too many products still rely on cheap carbs and fillers like maltodextrin and binding agents.

That’s why we built Kaiju, to support your performance today without compromising your health tomorrow. We build formulas the same way we approach performance, starting from physiology and the real world, then focusing on dose, bioavailability, absorption, consistency, and ease of use. I’ve been closely involved in that work from day one.

OSMØ® is the first technology we developed at Kaiju. It's based on the ratio of ions in the sodium-potassium pump. This process maintains crucial concentration gradients, establishes cell potential, regulates cell volume, and enables nerve impulses, nutrient transport, and cell signaling. It consists of 3 sodium ions moving out of the cell and 2 potassium ions moving inside the cell per cell cycle. OSMO's 3:2 ratio is designed to support optimal function at a cellular level.

Kaiju is something I use every day in training and in competition. It is designed to be reliable, consistent and easy to trust as part of a routine.

I am proud of what we have built so far, and of the level of care behind every formula.
