Your Questions, Answered
What is “Check My Batch”?
“Check My Batch” is our quality assurance initiative that lets you view third-party test results for your specific tub of ISOLATE. Just enter your lot number to see verified data on protein and fat content—so you know exactly what you’re getting.
Why do you only test protein and fat content?
We test what can be measured with accuracy. While protein and fat are tested directly, carbohydrate content in the majority of food labs is typically calculated, not tested. Most food labs estimate carbs using a formula that subtracts measured components like protein, fat, moisture, and ash from 100%. This method often overestimates carbs by mistakenly including sweeteners and flavourings that don’t contain calories or carbohydrates. We prefer to show you what we can prove.
Does the test show the exact nutritional content of my tub?
Yes—for protein and fat, the results are specific to your batch and reflect actual lab-tested values. These results are compared directly to our label claims to ensure accuracy and integrity.
Are these tests done in-house or by a third party?
All tests are conducted by independent, third-party laboratories. This ensures objectivity, accuracy, and full transparency. We don’t grade our own homework.
What if my tub doesn’t meet the label claims?
We test each batch before it ships—if it doesn’t meet our standards, it doesn’t leave our facility. The batch you’re checking has already passed our quality criteria, and these test results are shared so you can see that for yourself.
Why don’t other brands do this?
Many brands rely on theoretical formulations or dry weight percentages to claim higher numbers. At Day One, we test on an “as-is” basis and publish real results—because trust isn’t built with shortcuts. It’s earned with proof.
Can I use this data to compare Day One with other proteins?
Absolutely—but keep in mind most brands
use calculated estimates or dry basis claims, which can misrepresent true protein per scoop. Our results are based on as-is
testing, which shows you exactly what you’re getting.
