7 Best Oat Milk Brands to Buy, According to Dietitians

Oat milk has easily become one of the most popular dairy milk alternatives and it's made from one of the cheapest and most common pantry staples in existence: rolled oats.

If you're scratching your head wondering how in the world people make something resembling milk from oats, we get it. But the process isn't actually that mysterious. You just mix oats and water, puree in a blender, and strain. Now you've got a creamy liquid to use as a substitute for cow's milk in many recipes (or, just as a cold glass at breakfast).

But that still doesn't answer the more important question of why you might go through all the trouble to make oat milk (or search for it at your local health food store). Is it actually better for you than plain ol' cow's milk?

What are the health benefits of drinking oat milk?

Nicole Magryta, RDN, author of Nourish Your Tribe, says most oat milks contain one to three grams of fiber per serving (which is a little more than an alternative milk like almond), but also contain more calories and carbohydrates. In other words, you're kind of coming out even unless you're buying fortified oat milk from a supermarket.

"The health benefits of the milk itself are not necessarily from the oats and water, which offer marginal benefits, but from the fortified nutrients added during processing," says Magryta. "[Micronutrients like] vitamins A, D, B12, B2 and calcium are added so the product can be a close nutritional substitute for dairy milk."

What about homemade, unfortified oat milk… is there any point to drinking it? Yes, but mostly only if you need to avoid cow's milk because of an allergy or want to support a more sustainable alternative, says Magryta. Because sensitivities or allergies to oats are uncommon, oat milk gives people with dietary restrictions on soy, dairy, or nuts another beverage alternative.

How to choose the best oat milk

If you fit the bill for someone looking to consume a plant-based alternative to dairy milk, it's important to know what else you might be getting when you grab a container off the supermarket shelf. Registered dietitian Sarah Rueven, MS, RDN, CDN, founder of Rooted Wellness, says the best oat milks are made with just oats and water, without the added ingredients companies claim improve the taste and texture.

Here's what to check for on oat milk labels before you buy:

  • Choose milk made from organic oats. "Conventional oats are commonly sprayed with glyphosate as a drying agent before harvest," says Magryta, "which is a heavily-used chemical weed killer now labeled by the World Health Organization as a probable carcinogen." She adds that some recent tests of oat-based products have shown high levels of glyphosate residue and that organic products are less likely to be contaminated (and therefore safer for consumption).
  • Avoid added sugar and phosphates. Magryta says you definitely want to steer clear of sweetened varieties, but that you may also want to avoid brands with added phosphates. Although the Food and Drug Administration includes phosphates on its Generally Recognized as Safe (GRAS) list, it's a question of quantity. "Natural organic phosphate esters do occur naturally in foods like dairy, but in much lower concentrations," explains Magryta. "We, as a population, are consuming much higher quantities of phosphate from industrially-processed foods which [causes] safety concerns."
  • Skip "barista" varieties. Marketed as an option designed to be blended into popular coffeehouse-style beverages like lattes, barista oat milks are specially formulated to foam and steam—but that means the ingredient list is not as simple as oats and water. Most of these versions contain a seed oil, like sunflower or safflower, which Rueven recommends avoiding: "These oils are high in omega-6 fatty acids, and overconsumption can disrupt our omega-3 to omega-6 ratio, causing inflammation."

The 7 healthiest oat milk brands you can buy

Ready to shop? This list of healthy oat milk options will take all the guesswork out of buying alternative, plant-based milks at the supermarket.


Thrive Market Organic Original Unsweetened Oat Beverage

1 cup (237 mL): 110 calories, 2 g fat, 0 g saturated fat, 20 g carbs, 1 g fiber, 13 g sugar, 3 g protein

"This product has just two ingredients: water and organic oats," says Magryta. It also contains no added sugars, oils, or preservatives, making it a clean choice overall. One note: it's not fortified with nutrients, so it doesn't have the same nutrition profile as cow's milk or other alternative milk options

1 cup (240 mL): 90 calories, 1 g fat, 0 g saturated fat, 16 g carbs, 2 g fiber, 7 g sugar, 3 g protein

Magryta says Oatly! milk is made from gluten-free oats, certified Non-GMO, doesn't contain gums or traditional thickeners, and also carries the Glyphosate Residue Free certification by The Detox Project.

"A problem with most versions of this product is that they contain grape seed oil, which is an inflammatory industrial seed oil," she adds. "To avoid this, I recommend purchasing their low-fat option which leaves the oil out."

This drinkable yogurt beverage from Halsa—a brand using sustainably-grown Scandinavian organic oats—has nearly two grams of fiber and five grams of protein per serving. It also meets the dietitian-preferred requirements of containing no GMO ingredients, phosphates, gums, or oils. The only caveat here is the sugar (18 grams for the blueberry variety). Luckily, it's the naturally occurring kind from the real fruit added, not the added or artificial kind.

Yes, we did tell you to skip barista-formulated oat milk, but that was because most varieties include industrial seed oils. The Elmhurst brand doesn't, though, which is why it's Eat This-approved. Plus, it has two grams of fiber, three grams of protein, no carrageenan or gluten, and is non-GMO verified. If you're going to go barista, Elmhurst is your best bet.

The 3 worst oat milks you can buy

Sometimes products sold as "healthy" alternatives aren't actually all that healthy for you, and oat milk is no exception. Added sugars and industrial seed oils are big red flags, and are common in milk alternatives. Avoid the following oat milk brands the next time you're looking for a dairy milk substitute.


Califia Farms Oat Milk

1 cup (240 mL): 130 calories, 7 g fat, 1 g saturated fat, 15 g carbs, 0 g fiber, 4 g sugar, 2 g protein

This brand offers traditional and barista varieties but many are low in fiber and protein, making them a pretty empty choice, nutritionally speaking. Plus, Magryta points out that the unsweetened variety contains seven grams of fat from inflammatory sunflower oil.


Silk Oat Yeah! Milk

1 cup (240 mL): 120 calories, 5 g fat, 0.5 g saturated fat, 18 g carbs, 0 g fiber, 7 g sugar, 1 g protein

"This oat milk is a no-go with a long list of pro-inflammatory oil, additives, gums, and preservatives," says Rueven. Magryta agrees, adding that it's also not organic and made with sunflower oil. Basically, it checks all the wrong boxes.


Pacific Foods Oat Organic Original
