Fairlife's Official Stance on Added Hormones
Fairlife, and its parent company Coca-Cola, explicitly state that their milk is produced without the use of artificial growth hormones, specifically recombinant bovine somatotropin (rBST). This is a standard practice for many dairy producers today, and it is a claim the brand highlights on its packaging and in its marketing materials.
Understanding rBST and the FDA’s Position
Recombinant bovine somatotropin, or rBST, is a synthetic hormone historically used in some dairy farms to increase milk production in cows. However, a key point of clarification from the U.S. Food and Drug Administration (FDA) is that it has found no significant difference between milk from cows treated with rBST and those that are not. This FDA statement often accompanies 'no rBST' claims on product labels, including Fairlife's. The presence of this disclaimer is legally required and ensures transparency, acknowledging the scientific debate around the hormone.
The Difference Between Added and Natural Hormones
It is important to distinguish between hormones that are added and those that naturally occur. While Fairlife does not use added artificial hormones, all milk, regardless of the cow's treatment, contains naturally occurring hormones and other biological components. These include prolactin, oxytocin, and others. The presence of these natural compounds is an unavoidable aspect of dairy farming and is not affected by the rBST-free status.
The Ultra-Filtration Process
Fairlife’s primary innovation lies in its ultra-filtration process, which sets its nutritional profile apart from conventional milk. This patented cold-filtration technique allows the company to separate milk into its core components—water, lactose, protein, vitamins, and minerals—and then recombine them to achieve a specific nutritional balance.
How Ultra-Filtration Affects the Milk
The ultra-filtration process has several notable effects on the final product:
- Higher Protein: It concentrates the naturally occurring milk proteins, resulting in 50% more protein per serving compared to regular milk.
- Lower Sugar: It filters out much of the natural lactose (a sugar), reducing the sugar content by 50%.
- Lactose-Free: The filtration, combined with the addition of a lactase enzyme, makes the milk lactose-free, benefiting those with lactose intolerance.
- Creamier Texture: The process and resulting composition give the milk a distinctively rich and creamy taste.
Fairlife vs. Regular Milk: A Comparison
To better understand the differences, here is a comparison of Fairlife ultra-filtered milk and conventional regular milk.
| Feature | Fairlife Ultra-Filtered Milk | Regular Milk |
|---|---|---|
| Added Hormones | No (rBST-free) | May contain milk from rBST-treated cows |
| Natural Hormones | Yes (Naturally Occurring) | Yes (Naturally Occurring) |
| Processing Method | Ultra-filtration, separation, and recombination | Standard pasteurization and homogenization |
| Protein Content | 50% more protein | Standard protein levels |
| Sugar Content | 50% less sugar (lactose) | Higher natural sugar (lactose) content |
| Lactose | Lactose-free | Contains lactose, unless specified otherwise |
| Taste | Often described as richer and creamier | Standard milk taste |
Additional Considerations and Controversies
While Fairlife can confidently claim "no added hormones," the brand has faced other controversies that have sparked consumer questions. In the past, Fairlife suppliers have been subject to lawsuits and animal cruelty allegations. The company has settled some of these claims and has stated it strengthened its animal welfare oversight. However, new allegations and lawsuits have been filed as recently as 2025.
Separately, Consumer Reports has raised concerns regarding the presence of phthalates, a type of plasticizer, in some of Fairlife's protein shake products. These chemicals can interfere with hormone regulation. It is crucial to note that this is a separate issue from added hormones and refers to a potential contaminant in the product, not an intentional additive.
Conclusion
In summary, Fairlife is upfront about its non-use of artificial growth hormones like rBST, a practice consistent with many modern dairy farms and verified by labeling. However, like all milk, it does contain naturally occurring hormones. The brand's defining characteristic is its ultra-filtration process, which modifies the milk's nutritional composition to deliver more protein and less sugar. Consumers should be aware that the 'no added hormones' claim does not address concerns related to other controversies, such as past animal welfare issues or potential contaminants like phthalates. Ultimately, understanding these distinctions allows consumers to make a more informed choice based on their priorities, whether they are focused on nutritional content, processing methods, or ethical considerations.
