Is Fairlife Milk Ultra Processed?
Not Typically Ultra-Processed
Fairlife milk is Level 3 — significantly more processed than regular milk. It uses ultrafiltration technology to push milk through specialized membranes that separate it into its component parts (water, lactose, fat, protein, vitamins), then reassembles them in different ratios to create a high-protein, low-sugar product.
Key Findings
- •Ultrafiltration separates milk into water, lactose, fat, protein, and minerals through polymer membranes, then reassembles them in custom ratios
- •Fairlife has 50% more protein and 50% less sugar than regular milk — achieved through industrial fractionation, not traditional dairy processing
- •The membrane technology used was adapted from pharmaceutical and water treatment applications
Why Is Fairlife Milk Level 3?
Fairlife's process goes well beyond pasteurization: raw milk is pushed through a series of increasingly fine polymer membranes in a process called cold ultrafiltration. These membranes sort molecules by size — first removing fat, then separating protein from lactose and water. The components are then recombined: more protein is added back (50% more than regular milk), most lactose is removed (reducing sugar), and lactase enzyme is added to break down remaining lactose for lactose-free claims. This membrane filtration technology was originally developed for pharmaceutical and industrial applications. The result is nutritionally engineered milk — 13g protein and 6g sugar per cup vs regular milk's 8g protein and 12g sugar — but it is fundamentally a deconstructed and reconstructed food.

How to Read Fairlife Milk Labels
- 1
Fairlife lists: ultra-filtered milk, lactase enzyme — a deceptively short list for a complex process
- 2
The "ultra-filtered" designation indicates membrane separation and reassembly of components
- 3
Higher protein (13g vs 8g) and lower sugar (6g vs 12g) are achieved through industrial separation, not by adding or removing ingredients traditionally
- 4
Compare with regular milk's single ingredient: this is engineered nutrition from the same source
Frequently Asked Questions
Is Fairlife milk healthier than regular milk?
Fairlife has more protein and less sugar, but it is more processed (Level 3 vs Level 1). The nutritional advantages come from industrial membrane separation, not from inherently better milk. Whether the engineered nutrition offsets the increased processing is a personal judgment.
How is Fairlife different from regular milk?
Regular milk is pasteurized and homogenized — two physical processes. Fairlife adds ultrafiltration: milk is pushed through membranes that separate its components, which are then recombined in different proportions. It is fundamentally deconstructed and reassembled milk.
Is Fairlife lactose-free?
Yes. The ultrafiltration process removes most lactose, and lactase enzyme breaks down what remains. This is a more industrial approach than simply adding lactase to regular milk, which is what most lactose-free milks do (like Lactaid).
