It didn’t begin as a global business plan. There was no slick branding exercise, no venture capital seed round, and certainly no marketing war chest. Instead, the story of Rapid Nutrition, now a publicly traded wellness company with distribution across Australia, China, the UK, the U.S., and continental Europe, began with a personal need and a blender on a kitchen counter in suburban Brisbane.

Founded by Simon St Ledger, a former health club manager and personal trainer, Rapid Nutrition’s origin story is as authentic as they come. And that authenticity has turned out to be the company’s greatest asset.

“We didn’t start this thinking we were going to build a global brand,” St Ledger says. “We just couldn’t find a product that met our needs. And when we realized others had the same problem, we knew we had something special.”

At the time, St Ledger was managing and part-owning a fitness facility, where he and his team sold third-party supplements to members. He was deeply embedded in the industry, collaborating weekly with a dietitian and intimately aware of what made a product not just marketable but actually effective.

His wife, Leisa, was a full-time police officer: active, health-conscious, and now, a mother. But despite her knowledge of fitness and nutrition, there was no product on the market that met her needs: a high-protein, low-fat, high-fiber meal replacement without the artificial fillers and unnecessary sugars that dominated the shelves.

So, together with the dietitian, Simon developed a custom product — not for mass production, but simply for Leisa. “There was zero commercial intent,” he recalls. “It was made for her, because nothing out there was good enough.”

Still, economies of scale kicked in. Manufacturing the product meant ordering in bulk, and selling a few extra kilos to gym members seemed logical. “We literally bagged it ourselves and sold it at the gym,” says Simon. “And it worked. People loved it.”

From there, things moved quickly. The product gained traction not because of fancy branding but because people connected with Leisa’s story. She wasn’t a celebrity or a bodybuilder; she was a working mum juggling a demanding job and young kids, trying to stay healthy and energized.

With no marketing budget, Simon turned that authenticity into the brand’s unique edge. They called it Leisa’s Secret, and Leisa herself became the face of the company, appearing in media segments, packaging, and ads. “She represented the real consumer,” Simon explains. “Not the gym freak, but the parent, the worker, the everyday person trying to feel better.”

The media noticed. A national TV program picked up the story. The brand was featured quite a few times in prime time. “The audience response was overwhelming,” Simon says. “That was our breakthrough moment.”

The brand evolved with its success. As Leisa took a step back from the business, they rebranded from Leisa’s Secret to SystemLS™, a nod both to her initials (Leisa St Ledger) and to the concept of a complete lifestyle system. Product lines expanded: multivitamins became nutrient-rich green powders made from sea vegetables, wheatgrass, and organic fruits. Protein powders went vegan, flavors diversified, and with that, the demand grew.

“We were ahead of the curve on a lot of things,” says Simon, referencing the global rise in plant-based nutrition and clean-label trends. “But what stayed the same was our commitment to whole food–based solutions.”

By 2004, Rapid Nutrition had entered the export market, starting with China after an introduction through the Australian state government. Asia led to the Middle East, and the team began laying the foundation for global reach. In 2008, they raised AU$500,000, a stepping stone to going public.

But instead of listing in Australia, where the market favored resource and telco stocks at that time, the team structured a UK-based holding company and later listed publicly in Paris. The reasoning? “UK law mirrored Australian law, and the Euronext gave us more visibility and credibility internationally,” says St Ledger.

Since then, Rapid Nutrition has raised millions, built a network of institutional investors in Switzerland and the UK, and expanded into single-serve sachets for convenience markets in Asia. France has become a priority market due to its strict stance on artificial preservatives and consumer demand for clean-label products. “If Rapid Nutrition keeps its transparency pledge,” noted one analyst, “it could become a template for mid-cap wellness brands.”

From the beginning, St Ledger was clear: the product alone wasn’t enough. Customers needed to understand how nutrition, sleep, exercise, and mindset all played into wellness. “Education was built into the DNA of the business,” he says. “From early DVDs and eBooks to today’s online programs and recipe guides, it’s always been about more than just selling shakes.”

To further this mission, Rapid Nutrition teamed up with celebrity chef Jason Roberts, well-known in Australia and the U.S., to create family-friendly, protein-rich recipes that made health both practical and delicious. “We didn’t want to be another brand selling dusty tubs on shelves,” says Simon. “We wanted to be part of people’s daily lives to help make better choices easier.”

Rapid Nutrition may have outgrown its humble roots, but its founder still defines success not by market share, but by impact. “We still measure it one shaker bottle at a time,” says the founder. “If a customer understands why each ingredient is there, and how it fits into their life, we’ve done our job.”
