Fairlife has drawn criticism on several fronts: a documented animal abuse scandal at its flagship supplier farm, high levels of plastic-linked chemicals found in some products, artificial sweeteners and additives in its shake lines, and questions about whether its ultra-filtered milk is worth the premium price. Here’s what each of those concerns actually involves.
The Animal Abuse Scandal
The most damaging controversy hit Fairlife in 2019, when the Animal Recovery Mission released undercover video footage from Fair Oaks Farms in Indiana, the farm Fairlife had long featured in its marketing. The footage showed workers dragging calves by their ears, throwing them into small plastic enclosures, hitting them with milk bottles, and kicking and beating them. Calves appeared to be kept in filthy, overcrowded hutches where temperature readings exceeded 100 degrees. Dead calves were dumped in mass grave sites. The organization also alleged that supervisors and farm owners were aware of the conditions and participated in the abuse.
This was especially damaging because Fairlife had built its brand around the idea that its cows received “extraordinary care and comfort.” That phrase became the basis of a class-action lawsuit accusing the company of misleading consumers. In 2022, after Coca-Cola had fully acquired Fairlife for an initial payment of $980 million, the company settled those claims for $21 million. As part of the settlement, Fairlife agreed to implement animal welfare standards and third-party audits across its supply farms, though it denied wrongdoing.
The problems haven’t entirely gone away. As recently as 2025, questions surfaced about traceability gaps in Fairlife’s supply chain, with a New Mexico dairy called Woodcrest facing an active state investigation by the Livestock Board. Fairlife stated Woodcrest was not a supplier during 2024 or 2025 and that its current supplying farms are subject to welfare standards and third-party audits. Whether those audits are rigorous enough remains an open question for consumers who were burned by the original scandal.
Phthalates in Core Power Shakes
A Consumer Reports investigation tested a wide range of grocery products for phthalates, chemicals used to make plastics flexible that can leach into food during processing or packaging. Phthalates are linked to hormone disruption, and the results put one Fairlife product near the top of the list. Fairlife Core Power High Protein Chocolate Milkshake contained 20,452 nanograms of total phthalates per serving, the highest of any dairy product tested. For comparison, the next highest dairy product (a SlimFast shake) had about 16,900 nanograms, while organic whole milk in a carton had roughly 4,600.
Consumer Reports noted that phthalate levels didn’t depend on packaging type alone, and no single food category was consistently worse than another. High levels also showed up in canned peaches, fast food, and yogurt. Still, the Core Power result stood out. If you’re trying to minimize phthalate exposure, protein shakes sold in plastic bottles appear to be a higher-risk category.
Artificial Sweeteners and Additives
The criticism here depends on which Fairlife product you’re looking at. Fairlife’s plain ultra-filtered milk (the kind sold in cartons as a direct milk replacement) has a short ingredient list: ultra-filtered milk, lactase enzyme, and added vitamins A and D. No artificial sweeteners, no gums, no added sugar.
The shake and meal-replacement lines are a different story. Fairlife’s Nutrition Plan Chocolate shake, for example, contains acesulfame potassium, sucralose, and stevia leaf extract, three different non-sugar sweeteners in a single product. It also includes cellulose gel, cellulose gum, and carrageenan, all used as thickeners and stabilizers. Carrageenan in particular has been a point of debate for years. Some people report digestive discomfort from it, and certain consumer advocacy groups have pushed for its removal from food products. Cellulose gum is generally considered harmless, but its presence in what’s marketed as a premium dairy product strikes some consumers as contradictory to the brand’s “pure” image.
If you’re buying plain Fairlife milk, the ingredient concern is minimal. If you’re buying the shakes, you’re getting a processed product with a long ingredient list that includes multiple artificial sweeteners.
What Ultra-Filtration Actually Changes
Fairlife’s core selling point is ultra-filtration, a process that pushes milk through membranes to concentrate protein and remove some of the lactose (milk sugar). The result: 13 grams of protein per cup versus 8 grams in regular 2% milk, and 6 grams of sugar versus 12 grams. Lactase enzyme is added so the remaining lactose is broken down, making it easier to digest for people with lactose intolerance.
Critics point out that this is mechanical processing, not magic. Research published in the Journal of Food Science found that ultra-filtration affects mineral retention in variable ways. Individual mineral recoveries in concentrated milk ranged from roughly 50% to over 90%, meaning some minerals are partially lost in the filtration process. The protein boost is real, but you could get comparable protein from a glass of regular milk plus a handful of almonds, or simply by eating a slightly larger portion of any protein-rich food, without paying the Fairlife premium (which typically runs two to three times the price of conventional milk).
There’s also a philosophical objection. Some consumers feel that heavily processing milk to alter its macronutrient profile, then marketing it as a superior version of a whole food, is misleading. Milk already has a well-established nutritional profile. Whether concentrating its protein while stripping out some sugar makes it meaningfully “better” depends on your dietary priorities.
The Coca-Cola Connection
Fairlife is fully owned by Coca-Cola, which acquired it in a deal initially valued at $980 million. For some consumers, this is a concern in itself. The brand’s marketing leans heavily on imagery of small-farm values, happy cows, and premium quality. The reality is that it’s a product line owned by one of the world’s largest beverage corporations, sourcing from industrial-scale dairy operations. That gap between branding and reality is what fueled the class-action lawsuit and continues to make some consumers skeptical of the company’s welfare and quality claims.
None of this means Fairlife milk is unsafe to drink. Its plain ultra-filtered milk is a legitimate, minimally processed dairy product with more protein and less sugar than conventional milk. But the brand carries real baggage: a severe, documented animal welfare failure, phthalate levels in its shake products that ranked among the highest tested by Consumer Reports, and a premium price attached to a product owned by a multinational corporation. Whether those factors matter enough to avoid it is a personal call, but they’re the reasons the criticism exists.
