12 Best High-Protein Milks Ranked (Dairy AND Vegan)

Glasses of milk on table

Milk—whether from the cow or the coconut tree—has long been celebrated for its nutritional benefits.

I mean, we all remember those “Got Milk?” ads from the 90s and 2000s, right?

From the creamy texture of cow’s milk to the nutty flavor of nut-based options, milk is a staple in many diets. But have you ever wondered which milk offers the most protein?

Or how plant-based milks stack up against regular cow’s milk?

If you’re on a quest for the perfect blend of calories and grams of protein, you’re in the right place!

In this guide, we’ll explore the world of dairy and non-dairy milk, ranking them to help you find the best sources of protein.

Whether you’re a fan of whole milk, vegan milk, or something in between, I’ve got you covered.

Is Milk a Good Protein Source?

Milk protein source

Milk has been a staple in human diets pretty much forever, and it is often praised for its rich vitamin and mineral content. But what about protein?

As you probably know, protein is essential for muscle growth, immune function, and overall health. Milk, both dairy and plant-based, can be a great source of protein, but not all milk is created equally.

Dairy milk generally contains complete proteins, providing all the essential amino acids your body needs (and are ideal for muscle building).

Plant-based milk can come from a variety of different sources, some of which are complete protein, but that is certainly not always the case.

Every milk is different. The protein content can vary widely, depending on the type of milk and how it’s processed.

That’s why it’s essential to choose the right milk for your lifestyle. Whether that means something dairy-based or vegan, it’s important to base your selection off of what is most important to you.

In this post, I’ll break down the best dairy-based and vegan milks, ranking them by their calories-to-protein ratio. Using this method ensures we find the best sources of protein, not just the highest protein content.

So, is milk a good protein source? Absolutely!

But choosing the right one can make all the difference.

Ranking Milk: Understanding the Calories-to-Protein Ratio

When it comes to evaluating the best milk options for protein content, I chose to rank them based on a specific metric: the calorie-to-protein ratio. But what does this ratio mean, and why is it important?

The calories-to-protein ratio represents the number of calories per gram of protein in a food or beverage. It’s a way to measure how efficiently you can obtain protein from a particular source while considering the energy content (calories).

In simple terms, a lower ratio means you’re getting more protein for fewer calories, which makes it a better source of protein.

Ranking milk by this ratio provides a balanced view of both the protein content and the overall nutritional value. If a specific option has a lot of protein but also a ton of extra calories, we don’t want to view that as the best source of protein.

Whether you’re looking for the creamiest option with the most protein or a plant-based alternative with a great balance of macros, understanding this ratio is key.

Best Dairy-Based Milk Options for Protein

Classic cow’s milk is the gold standard when it comes to milk, but it’s far from the only option. These days, we have a ton of additional options on top of the classic, so let’s explore them.

Skim plus milk

110 Calories, 0g Fat, 16g Carbs (16g Sugar), 11g Protein

Skim Plus Milk stands out with 11g of protein and no fat, making it similar to skim milk, but not quite as good of a protein source.

The “plus” is in the taste, and this is much creamier milk than your standard fat-free milk. It’s also lactose-free, which can make it much easier on the stomach for many people.

With a calorie-to-protein ratio of 10 (10 calories for every gram of protein), it’s a solid option for protein intake. The higher carb content might be something to consider, but its unique blend offers a distinctive taste that sets it apart from regular skim milk.

3. Skim Milk

Skim milk

80 Calories, 0g Fat, 12g Carbs (12g Sugar), 8g Protein

A classic choice, skim milk provides 8g of protein with no fat, ranking it with a ratio of 10 calories-per-gram of protein.

It’s a good choice for those watching their fat intake and offers the familiar taste and nutritional benefits that we’re all familiar with.

Other Milk Options

While the dairy and vegan milks listed above are ranked for their protein content, there are plenty of other options that might not pack as much protein but still offer unique flavors and health benefits.

Let’s explore some of them…

Coconut Milk

coconut milk

Coconut milk is known for its creamy consistency and tropical flavor.

While it might not be the best non-dairy milk in terms of protein, it’s rich in healthy fatty acids and provides a great way to elevate creamy recipes.

Since coconut milk is generally high in fat and calories, it’s typically consumed on low-carb & high-fat diets.

Hemp Milk

Hemp milk

Made from hemp seeds, hemp milk offers a slightly grassy and nutty flavor that’s unique among plant-based milks.

Its texture is often described as creamier than almond milk but less thick than cow’s milk (similar to oat milk).

Rice Milk

Rice milk

Rice milk is a dairy-free option that’s pretty comparable to almond milk. While it doesn’t provide much protein, it’s often enriched with vitamins and minerals, making it a good option for those with nut allergies.

Cashew Milk

Cashew milk

Cashew milk is celebrated for its creamy texture and rich, nutty flavor. It’s often used in plant-based diets as a whole milk substitute, and though it might not have the most protein, its taste and consistency make it a very popular choice.

Unsweetened Almond Milk

Almond milk

Unsweetened almond milk is the go-to option when calories are limited.

In the fitness space, it’s often used to mix with protein powder to make protein shakes with a better consistency than water can provide.

If you want to keep your calories and carbs down, and don’t mind the lack of protein, this is the way to go.

Protein Quality in Dairy and Non-Dairy Milks

Protein quality is an important thing to consider, especially when comparing dairy and plant-based milk alternatives.

You may have heard the term “complete protein” flying around as it pertains to dairy or plant-based milk, but what exactly does that mean?

Dairy Milk Protein Quality

Cow’s milk and other dairy products typically provide complete proteins, meaning they contain all nine essential amino acids. This makes dairy milk an excellent source of protein, with a well-rounded amino acid profile.

The protein in dairy milk is usually easily digestible, allowing for efficient absorption. Whether it’s whole milk or skim, the protein quality in dairy milk is generally very high.

This is one of the main reasons why whey protein is the preferred supplement for building muscle and plant-based protein often takes a back seat (that doesn’t make plant-based protein bad, just not as high in quality as dairy-based).

Non-Dairy Milk Protein Quality

Plant-based milk offers a different protein profile. While some, like soy milk, provide complete proteins, most others lack certain essential amino acids.

For example, rice milk might be lower in lysine, keeping it from being a complete source of protein.

Hemp milk provides a good balance of omega fatty acids, and nut milks, like almond and cashew, might be lower in protein but still provide valuable nutrients as well.

So, while the protein quality might not be quite as high as dary options, there are lots of other nutritional benefits to take into account.

Blended options, like Silk Protein, combine different plant proteins to create a more balanced amino acid profile. This approach enhances the overall protein quality, making it suitable for those on a strict plant-based diet who need complete protein.

Both dairy and non-dairy milk have their place in a balanced diet, whether or not they qualify as a complete protein.

Whether you prefer the creamy texture of cow’s milk or the nutty flavor of plant-based milk, there’s a protein source for your preferences.
