What These New Protein Beverages Mean for Nutrition and the Ongoing Conversation Around Diet Culture
Dunkin’ joined the protein drink trend, and naturally, my Salad With a Side of Fries community started asking questions. As a health and lifestyle coach, this happens all the time. On my podcast and social media, we love getting curious, looking beyond the headlines, and figuring out what’s meaningful information versus powerful marketing.
When Starbucks launched its protein beverages, I asked baristas and even a regional manager more questions than they probably expected. Fast forward to early 2026, and Dunkin’ introduced its own Dunkin’ Protein Drinks. I took the same approach. Same curiosity, same questions, different coffee shop.
Before I stepped into the store, I spent some time reviewing Dunkin’s website and tracking down the company’s press release. I like to do my homework first. The announcement highlighted something called protein milk, referenced a partnership with Megan Thee Stallion, and focused on protein refreshers and protein lattes. It also mentioned both dairy and non dairy options, which immediately landed on my list of questions.
Here’s where things became interesting. Dunkin’ provides a nutrition facts PDF on its website, and I will say it offers more transparency than what I encountered elsewhere. The press release states that a medium beverage delivers 15 grams of protein. Yet when reviewing the nutrition facts, some medium drinks contain 10 grams while certain larger beverages contain 13 grams. The takeaway is the same as always. Check the nutrition information for the specific drink you plan to order. While you’re there, look beyond the protein number and review the entire nutrition profile.
Ready for some field research, I visited multiple Dunkin’ locations because the first store could not answer all my questions. Just as I had done elsewhere, I walked up to the counter and asked if I could see the protein source used in the drinks. The employees looked a little surprised and explained that there was no protein powder involved. Instead, Dunkin’ uses protein milk. Specifically, they use Lactaid Protein Milk. I genuinely appreciate that this is a real product consumers can find, review, and research on their own. Having access to a clearly labeled ingredient list makes evaluating nutrition much easier.
The employees at both Dunkin’ locations were incredibly kind and allowed me to look at the Lactaid carton. I also confirmed that this milk was the sole source of protein in the beverages. As for the non dairy option mentioned in the press release, I did not see it available at either location. That does not necessarily mean it is unavailable everywhere. I simply could not verify it firsthand.
Before leaving, one additional detail caught my attention. The menu featured an almond protein matcha latte. Naturally, I asked about it. I was told it was not made with almond milk. Instead, one employee showed me an almond flavored syrup and explained that it was sugar free. This highlights another important lesson. If you order a Dunkin’ Protein Drink expecting almond milk, that may not be what you receive. In the stores I visited, the beverage was made with Lactaid Protein Milk and flavored syrups. I have written about coffee syrups before because understanding sweeteners and additives matters. To fully evaluate the nutrition of these beverages, we need to look closely at the milk itself.
Lactaid is lactose free dairy milk, not a plant based product. That distinction matters. The company starts with cow’s milk and notes that the cows are not treated with artificial growth hormones. That is different from saying the milk is hormone free. Lactase enzymes are added to break down the naturally occurring milk sugar, making it more accessible for people with lactose sensitivity. The protein milk is also fortified with ultra filtered skim milk, increasing the protein content. If you’ve read my article about Fairlife, this process may sound familiar.
The ingredient list is refreshingly simple. It contains reduced fat milk, ultra filtered skim milk, lactase enzyme, vitamin A palmitate, and vitamin D3. One cup provides 150 calories, 5 grams of fat, 12 grams of carbohydrates, 11 grams of naturally occurring sugar with no added sugar, and 13 grams of protein. While the micronutrient profile is not especially robust, even with added vitamins, I appreciate the absence of sweeteners, gums, and emulsifiers.
Here’s my perspective as a health and lifestyle coach. Lactaid tastes very similar to traditional milk, which may appeal to many people. Personally, I have never been much of a milk person, so that alone is not a major selling point for me. The bigger question is whether this is something you would normally choose. If you are looking for a lactose free source of protein from a coffee shop, I can certainly understand why these Dunkin’ Protein Drinks might appeal to you. Just pay attention to the syrups, flavorings, and other additions that can change the overall nutrition profile.
One final thought. You do not need to add protein to every single thing you consume. I understand why brands are embracing the protein trend. Protein is having a major moment right now, fueled in part by social media messaging and aspects of modern diet culture. That does not mean every beverage needs a protein boost. If a protein drink fits your preferences and lifestyle, enjoy it. Just be mindful that the word protein does not become a permission slip for choices you would not otherwise make. Staying informed and intentional will always matter more than following the latest trend.
