No, not certified. The cattle by New Zealand law are not exposed to hormones, antibiotics, or any other foreign substances. They are grass fed, so it’s as close to organic as you can get.
It’s healthier than North American Whey because the cattle is never subjected to chemicals, Hormones, Antibiotics, GMO’s, or Hyper-Immunizations. They’re grass fed, not factory farmed, and are not exposed to the stress most American cattle endure, which cause the cattle to release harmful stress hormones.
It costs more due to transportation, the grazing practices, proper collection and storage methods, and processing, which all affect the quality of whey protein and the cost.
Yes it is pasteurized using UHT processing, meaning it is heated for a very short period, around 1–2 seconds, at a temperature exceeding 135°C (275°F), which is the temperature required to kill spores in milk. Because it's heated for such a short time this process prevents nutrient loss.
Yes, only the “Isolate” formula is because it contains no sugar (lactose).
