Precision Protein - Waikato Rugby Edition
Our New Zealand Precision Protein DIAAS Complex 1.61, now in a special Waikato Rugby edition celebrating 50 years of the National Provincial Championship and a region united through sport. This is our most bioavailable protein powder yet: up to 48% more bioavailable than pure whey protein isolate. Made with grass-fed New Zealand milk and whey, it delivers a complete amino acid profile, a clean nutritional profile, and a taste built for champions. Every scoop fuels performance. 12.1g essential amino acids, 5.9g BCAAs, just 1.2g sugar, and 115 kcal per serving, engineered for athletes and health enthusiasts who demand more from their nutrition. This partnership runs deep. Radix, Convex, and Waikato Rugby, three Waikato organisations collaborating to strengthen our region and the game we love. From paddock to powder, this is local excellence in every serving. Built for athletes. Built for Waikato.
Key Benefits
- Protein supports the growth, repair, and maintenance of tissue throughout the body. Getting enough of it can benefit athletic performance, long-term health, and longevity.
- Complex 1.61 is built using the Digestible Indispensable Amino Acid Score (DIAAS) the gold-standard method for measuring protein quality to maximise bioavailability and deliver an amino acid profile that's hard to match. That means faster recovery, better muscle growth, and improved overall performance.
- Grass-fed, New Zealand-sourced dairy for a cleaner ingredient profile from paddock to powder.
Nutrition at a Glance
- 12.1g Essential Amino Acids — the building blocks your body can't produce on its own, essential for muscle growth and repair.
- 5.9g BCAAs — leucine, isoleucine, and valine, supporting muscle growth, repair, and energy metabolism.
- 1.2g Sugar — zero added sugar; what's there occurs naturally in the main ingredients.
- 0.5g Fat — a lean, low-fat formula that supports muscle growth, weight management, and recovery.
-
115 kcal per serving — a high protein-to-calorie ratio for a genuinely lean protein powder.
The Waikato Collab
For more than a century, Waikato Rugby has brought communities together through a shared passion for the game. Every jersey represents the players who have worn it before, the supporters who fill the stands, the volunteers who keep our clubs thriving, and the next generation who dream of pulling on the red, yellow and black.
This year holds special significance as we celebrate 50 years of the National Provincial Championship, recognising five decades of unforgettable moments, legendary players and the proud legacy of Waikato Rugby. At the same time, our Waitomo Group Waikato FPC team is chasing a historic third consecutive premiership, adding another exciting chapter to our story.
Our partnership with Radix reflects the strength of the Waikato region and the power of local collaboration. This product is proudly fuelled by a Waikato business, packaged by fellow Waikato company Convex, and brought to life alongside Waikato Rugby. It is a great example of organisations from our region working together to achieve more.
That same spirit strengthens everything we do. The support of partners like Radix and Convex helps grow rugby from grassroots to the representative game, creating opportunities for players, coaches, referees and communities across the Waikato. Together, we honour our past, celebrate our present and build an even stronger future for Waikato Rugby and the Waikato region.

Formulated with Precision and Purpose
Radix Precision Protein is designed to reinforce the protein foundation when needs increase or consistency becomes harder to maintain.
Radix Precision Protein reinforces your protein foundation when demands increase or daily intake becomes harder to maintain.
More than single-source whey, it combines whey and casein to provide both rapid and sustained essential amino acid availability.
Helps close the protein gap when requirements exceed what meals alone typically provide.
Practical, reliable, and easy to use, making structured protein intake sustainable over time.

Reinforcing the Protein Foundation
RDX Precision Protein combines premium New Zealand whey and casein to provide both rapid and sustained protein and essential amino acid support.
This helps reinforce daily protein intake and maintain consistency when requirements are higher or harder to meet through meals alone.
It is functional protein designed with purpose - to strengthen your nutritional foundation, not just add protein on top.

Excellent Protein Quality
Estimated Using DIAAS-based Assessment Methodology
RDX Precision Protein is formulated to achieve excellent protein quality, based on a DIAAS-derived calculated estimate. This means that our protein provides all essential amino acids in amounts that meet or exceed established human reference requirements, even after accounting for digestibility.
Protein quality can be evaluated using scientific frameworks such as DIAAS
(Digestible Indispensable Amino Acid Score), which assess how well a protein’s digestible essential amino acids align with human needs.
RDX Precision Protein has a DIAAS estimate of 1.61, classified as “excellent” protein quality under established assessment criteria. This value represents a calculated estimate derived from amino acid composition and published digestibility data.
Because protein plays a central role within the Vitality System, assessing its quality using established scientific criteria supports our deliberate, protein-centred approach.
