How to Choose the Best Plant-Based Protein Powder for You

Just a few years ago, only a handful of companies sold plant-based protein powders. 

Now?

It’s hard to choose from the smorgasbord of options, all of which claim to be the best. 

What’s more, there are myriad different kinds of plant-based protein powder to choose from including soy, hemp, pea, rice, quinoa, fungal (mycoprotein), and more.

So, which one should you choose? 

What actually makes the best plant-based protein powder, anyway? 

You’ll learn the answer to all of these questions in this article. 

Instead of reviewing every product on the market, you’ll learn what to look for in a plant-based protein powder, the three best plant-based protein powders, and the single best plant-based protein powder supplement on the market today. 

Let’s get started. 

What Makes the Best Plant-Based Protein Powder?

Protein is a compound composed of chains of smaller molecules known as amino acids, which are the basic building blocks of every cell in your body. When you eat protein, your body breaks it down into amino acids, which are then absorbed and used to create new protein molecules.

Your body can mix and match many amino acids to make the proteins it needs, but it must get nine particular amino acids from the foods you eat.

These are known as essential amino acids (EAAs), because they must be obtained from the diet. They are:

1. Phenylalanine
2. Valine
3. Threonine
4. Tryptophan
5. Methionine
6. Leucine
7. Isoleucine
8. Lysine
9. Histidine

A protein’s amino acid profile is a breakdown of how much of each type of amino acid it contains.

Some proteins contain far more of certain amino acids than others, which makes them better or worse for building muscle.

Namely, proteins that have higher amounts of essential amino acids, and especially leucine, isoleucine, and valine (known as branched-chain amino acids or BCAAs), stimulate more muscle growth than those with less. Research also shows that leucine seems to be particularly effective for stimulating muscle growth, although it’s probably ideal to consume it with isoleucine and valine.

So, as a general rule, the best plant-based protein powders are going to have more essential amino acids (and especially BCAAs) than others. 

The next criteria to consider is how well a plant-based protein powder is digested, absorbed, and processed by the body.

The easier it is for your body to digest, absorb, and process a protein, the better it’s going to be for building muscle and improving health.

More specifically, protein digestibility refers to the percentage of protein in a food that your body actually absorbs and uses. For example, if you eat 30 grams of protein and your body ultimately absorbs 27 grams, then that food has a protein digestibility rating of 90%.

Thus, the higher the digestibility score, the better the protein is for building muscle.

And unfortunately for vegetarians, vegans, and those who eschew animal protein, plant-based protein powders (and proteins in general) have a protein digestibility score about 10% lower than animal foods on average.

For example, meat and fish clock in around 95%, whereas whole wheat bread is closer to 40%, and rice comes in at about 60% (the exact percentages can vary depending on the measurement method, but these are good ballpark figures).

Now, if you get protein from a variety of plant and animal sources, you’ll still be able to consume enough essential amino acids to cover your nutritional bases. 

If you get your protein exclusively or primarily from plant sources, however, it’s easy to fall short of your essential amino acid needs. This is one of the reasons omnivores tend to have more muscle mass—they usually eat and absorb more high-quality protein than vegans or vegetarians.

The good news is that if you eat the right combination of different plant proteins, you can still meet your essential amino acid needs and build muscle just as effectively as meat-eaters. 

In addition to a plant-based protein’s amino acid profile and digestibility, you may also want to consider its micronutritional value. That is, does it contain any other nutrients, in addition to essential amino acids?

Although you don’t want to rely on any kind of supplement (protein powder or otherwise) as a primary source of nutrition, if one kind of plant-based protein powder provides more micronutrients than another, why not choose that one? Every little bit helps, after all. 

Read: This Is the Definitive Guide to Micronutrients 

Since vegans and vegetarians tend to be the main consumers of plant-based protein powder, many companies have begun adding nutrients that tend to be lacking in meat-free diets, including vitamins B12, D, and K, and minerals like calcium, phosphorus, and iron. 

Finally—and this mostly goes without saying—you also want to consider the taste, texture, and more subjective qualities of different plant-based protein powders. 

While some plant-based protein powders may look more or less identical on paper in terms of their amino acid profile, digestibility, and nutritional density, they can still vary quite a bit in their taste, mouthfeel, and smell, which makes some plant proteins better choices than others. 

Summary: The two main criteria you should use to determine the best plant-based protein powder are its amino acid profile and digestibility, with micronutritional density and palatability being secondary concerns.

The 3 Best Plant-Based Proteins for Building Muscle

Pea Protein Powder

Pea protein’s main strengths are its excellent digestibility and abundance of leucine, which is the essential amino acid most directly responsible for muscle building. It’s also high in isoleucine, valine, and other essential amino acids, which makes it particularly good for building muscle. 

The one essential amino acid that you won’t find much of in pea protein is methionine. Luckily, there’s an easy solution for this problem that I’ll explain in a moment.

Specifically, a 25-gram serving of pea protein provides about 5.9 grams of essential amino acids and 1.4 grams of leucine. For comparison, a serving of whey protein provides about 8.5 grams of essential amino acids and almost 2.2 grams of leucine.

Thus, it’s not surprising that research shows pea protein is about as effective as whey protein for building muscle. 

An excellent example of this comes from a 2015 study conducted by scientists at the Center for Performance Expertise. In this study, the researchers evenly divided 161 men aged 18 to 35 into three groups: 

1. A pea protein group
2. A whey protein group
3. A placebo group

All of the men did biceps exercises three times per week for 12 weeks, and were told to consume 25 grams of either pea protein, whey protein, or placebo powder twice per day (depending on which group they were in).

To gauge the effectiveness of the different supplements, the researchers measured the subjects’ biceps thickness and strength before, half-way through, and after the study. 

They found that the pea protein group actually increased their biceps thickness slightly more than the whey protein group, although the difference wasn’t statistically significant. All three groups also gained about the same amount of strength.  

While other studies have found less impressive results, on the whole, pea protein seems to be about as good as whey protein for building muscle. 

One downside to pea protein, however, is that it tends to taste like, well . . . peas. Luckily, you can cover the taste by combining it with other plant-based protein powders like rice or quinoa. 

Summary: Pea protein is the single best plant-based protein because it’s rich in essential amino acids and easily digested and absorbed, and is more or less equally effective as whey protein for building muscle.

Rice Protein Powder

Rice protein is another top-tier source of plant-based protein because it’s absorbed well by the body and boasts a robust amino acid profile, similar to pea protein. 

Specifically, a 25-gram serving of rice protein provides about 5.5 grams of essential amino acids and 1.5 grams of leucine. For comparison, a serving of whey protein provides about 8.5 grams of essential amino acids and 2.2 grams of leucine.

The one essential amino acid you won’t find much of in rice protein is lysine, but again, there’s a simple solution for this I’ll share in a minute.

In terms of digestibility, rice protein is almost as good as pea protein, with around 70% of the protein being broken down and absorbed by the body.

All in all, rice protein is very similar to pea and whey protein in terms of its amino acid profile and digestibility, which is why research shows that it produces almost as much muscle growth as whey protein.

Finally, rice protein often has a mild, nutty taste that goes well with many other ingredients, which makes it an excellent choice for a plant-based protein powder.

Summary: Rice protein powder is rich in essential amino acids and easily absorbed, and when combined with pea protein, it offers benefits similar to those of whey protein. 

Quinoa Protein Powder

Quinoa protein is a relative newcomer to the world of plant-based proteins, but it’s become popular for good reason—it’s high in leucine and essential amino acids and easily digested.

Specifically, a 25-gram serving of quinoa protein provides about 8.2 grams of essential amino acids and 1.7 grams of leucine. For comparison, a serving of whey protein provides about 8.5 grams of essential amino acids and 2.2 grams of leucine.

Quinoa protein is also higher in micronutrients like magnesium, manganese, iron, and zinc compared to many other plant-based protein powders like hemp, wheat, and soy.

So, why is quinoa last on this list? 

Although it has a good amino acid profile and is about as easily digested as pea or rice protein, it also tends to have a grainy, unpleasant consistency, and doesn’t offer any significant benefits you can’t get from a combination of pea and rice protein.

In other words, there’s nothing inherently wrong with quinoa protein—it’s just a less appetizing alternative to pea and rice protein.

Summary: Quinoa protein has a good amino acid profile that’s similar to pea and rice protein, but it isn’t digested quite as well and tends to have a grainy, unpleasant consistency.
