Radix Whey F.A.Q.s
How does Radix Whey achieve a DIAAS score of 1.61?
Radix Whey's exceptional DIAAS score of 1.61 comes from its unique multi-source whey complex sourced from NZ grass-fed cows via Fonterra NZMP.
The blend combines three complementary protein fractions: Ultrafiltered Whey Protein Isolate (WPI), Whey Protein Concentrate (WPC), and Milk Protein Concentrate (MPC). Each fraction contributes a distinct amino acid profile, and together they achieve a digestible indispensable amino acid density that no single source can match alone.
For context: a standard WPI scores 1.09–1.30, WPC80 scores 0.97–1.10, and soy protein scores just 0.91.
Radix's complex at 1.61 means every gram of protein delivers significantly more usable EAAs to support muscle protein synthesis.
Is Radix Whey independently tested and certified?
Yes. Radix Whey is HASTA certified and WADA compliant, meaning it is tested for over 200 substances banned in sport. This provides assurance for competitive athletes at all levels.
The whey protein is sourced exclusively from Fonterra NZMP, New Zealand's largest dairy cooperative, using milk from free-range, grass-fed cows raised in New Zealand's natural pasture system. The product is free from gluten, soy, and artificial sweeteners, and is non-GMO.
With Radix Whey, you can be confident the product on the label is exactly what's in the tub — no contamination, no banned substances, no compromises.
