Best Oat Milks With Minimal Ingredients

Oat milk is a great option for those who have sensitivities or allergies to dairy, soy and nuts. But its nutritional content is quite different from other types of milk and depends on the specific ingredients, which vary from one brand to the next. That's why it's important to look for an oat milk with minimal ingredients, which likely means it's less processed than other options.


"The majority of oat milk brands on the market either have canola or sunflower oil added, which acts as an emulsifier," Angie Asche, RD, CSSD, a sports dietitian and owner of Eleat Sports Nutrition, tells LIVESTRONG.com. These oils aren't a concern when consumed in small amounts, she says, but in excess, they can be inflammatory.

She prefers Oatly! Low-Fat Oat Milk over some of the other brands because it doesn't contain any added oils.


Another oat milk with very few ingredients is Thrive Market's Organic Oat Beverage. In fact, there's just two: organic oats and spring water. Whereas many oat milks tend to be thick and creamy, Thrive's is more light and refreshing — perfect if you tend to drink it daily.

Brands We Love

  • Oatly! Low-Fat Oat Milk ($4.04 per 64-ounce carton on Amazon.com)
  • Thrive Market's Organic Oat Beverage ($8.99 per 34-ounce carton on Thrivemarket.com)

Best High-Protein, Low-Sugar Oat Milks

In addition to added sugars, oat milk typically has a higher carb content and lower protein content compared to dairy milk and other plant-based milk — so remember to read nutrition labels and portion accordingly.

It has just five ingredients: filtered water, whole grain oats, cane sugar, salt and natural flavors — and there are no added gums, oils or emulsifiers.

Best Unsweetened Oat Milks

Of course, for some people, even a low amount of sugar can feel like too much sugar. "Many milk alternatives that are labeled as 'original' are sneakily sweetened and this can be a surprise on that first sip," Leanne Ray, RDN, owner and founder of Leanne Ray Nutrition, says.


So if you notice a carton labeled "original," check out its ingredient list and nutrition facts label to avoid those added sugars. Mild-tasting Dream Oat Beverage Oat Unsweetened is a great option in this case: It has less than 1 gram of sugar per serving.

What's more, Silk Oat Yeah! Oat Milk has zero sugar and reviewers say it's so rich, creamy and smooth you won't even miss the sweet stuff!


Brands We Love

  • Dream Oat Beverage Oat Unsweetened ($3.33 per 32-ounce container on Amazon.com)
  • Silk Oat Yeah! Oat Milk ($3.99 per 64-ounce container on Instacart.com)

Best Oat Milks Fortified With Vitamins and Minerals

One of the benefits of store-bought oat milk versus oat milk you make at home is that many brands are fortified to provide a similar nutrient profile as milk. So you'll often find added calcium, vitamin D and B12 in these oat bevs.


"If you eat a mostly plant-based diet, you might have a harder time getting these nutrients, so it's great to get them in your plant milk," says Sharon Palmer, RDN. Like Asche, she loves Oatly!, which provides 25 percent of the recommended daily intake of calcium, as well as 20 percent and 50 percent of vitamins D and B12, respectively.

Planet Oat Extra Creamy oat milk is another fortified brand that's rich in calcium and other good stuff, providing 20 percent of the recommended daily intake of calcium, 10 percent of vitamin D and 40 percent of B12. "It's possible to meet your calcium needs with a plant-based diet, but it can take extra diligence to do so," Ray says. "Ensuring that your milk alternative is fortified is a great place to start, specifically if you consume it daily."

You can also try Oatsome Organic Oat Milk, which is also fortified with 20 percent of the recommended daily intake of calcium, 10 percent of vitamin D and 40 percent of B12.

The Takeaway

"Pick up whatever is available and fits within your budget and nutrition needs," Ray says. "Milk alternatives can be a fun way to shake things up in the kitchen and enjoy a variety of flavors and nutrients in your meals and snacks."
