• Complete essential amino acid profile
• Naturally rich in essential amino acids to support muscle recovery
• Source of key minerals including iron and calcium
Built for Quality and Consistency
• HASTA batch tested
• Made using high-quality plant ingredients
• 1 kg (2.2 lb) bag or 15 single serves
• 6 delicious flavours
Formulated with Precision and Purpose
RDX Precision Protein is designed to reinforce the protein foundation when needs increase or consistency becomes harder to maintain.
RDX 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.
The Four Pillars of Vitality
FAQ
Why does Radix focus so strongly on protein?
Because protein is foundational to vitality. It supports muscle maintenance, repair, recovery, and physical capability, and becomes increasingly important as demands increase with age, stress, or training.
Protein is not a “gym nutrient.” It’s a foundation nutrient.
Why use a protein powder instead of just eating more protein foods?
Whole foods are ideal, but real life isn’t always consistent. Many people fall short simply because time, appetite, and routine don’t always allow for high-quality protein at every meal.
Protein powder is a practical tool to close the gap when requirements are higher, or harder to meet through meals alone.
What makes Radix different from a standard whey protein?
Radix is not a generic whey powder. It is a precision whey + casein formulation designed for both fast and sustained protein support, with meaningful calcium contribution and no artificial sweeteners.
It is formulated for purpose, premium protein quality, and repeatable everyday performance, with a meaningful calcium contribution and no artificial sweeteners.
Why does a whey + casein blend matter?
Because whey and casein digest differently. Whey delivers amino acids quickly, while casein provides more sustained release.
When combined, they support both immediate impact and sustained coverage — helping support protein intake not just in the moment, but across the hours that follow.
What does “protein quality” actually mean?
Protein quality refers to how effectively a protein source supplies digestible essential amino acids compared to estimated human requirement patterns.
In other words: it reflects whether the protein delivers essential amino acids in the right balance, and whether those amino acids are actually absorbed and usable by the body.
Higher-quality proteins provide more usable essential amino acids per gram consumed, which becomes increasingly important when protein requirements are higher — such as during training, ageing, or recovery.
Why does Radix Protein Powder contain calcium?
Radix includes casein-rich milk proteins as part of its precision whey + casein design. Because calcium is naturally associated with milk proteins, Radix provides a meaningful calcium contribution as part of the formulation — supporting normal muscle function, nervous system function, energy metabolism, and digestive enzyme function. This supports the broader foundations of vitality, not just protein intake.
Does Radix Protein Powder contain artificial sweeteners?
No. Radix contains no artificial sweeteners and is naturally sweetened with monk fruit extract, making it suitable for consistent everyday use.
How often should I use Radix Protein Powder?
It’s designed for flexible everyday use. Some people use it at least daily while others might use it a few times per week.
The goal isn’t perfection, but consistency. Protein powder works best when it reinforces the foundation reliably over time.
