What vegan protein powder is the best?

I started Athlegan by writing about vegan protein and how it's no problem getting sufficient amounts. But we're athletes and we want optimal amounts! Protein powder is one easy way of getting that.

The World Health Organization recommends 0.8 gram of protein per kilo lean body mass1 but a more optimal level for building muscle is ~2 g per kg23. Especially for weight loss and for women4.

So just how much food gives this optimal level of protein?

What vegan protein powder is the best?

Let's keep the math simple and assume you're a 70 kg person with not a single gram of fat on your body. With 70 kg of lean body mass and if you strive for 2 g/kg, that's 140 grams of protein per day.

That's either one of:

  • 467 g (2701 kcal) peanut butter
  • 723 g (1338 kcal) taifun tofu
  • 1.5 kg (1753 kcal) lentils

While I'll never be one to turn down a scoop of peanut butter, I have to admit it'd be tough to eat half a kilo a day. Instead I'd rather limit it to a (heaped) scoop and supplement – with protein powder.

Protein powder nutrition #

There are a few different types of vegan protein powders. The most common ones are soy protein, hemp protein, brown rice protein, and pea protein.

Depending on the brand they can contain various amounts of protein as well, ranging anywhere from 40 grams per 100 grams, to 80 grams per 100 grams. Check out the label before you buy!

Besides the amount of protein, its quality also varies between types.

A protein is nothing more than a chain of amino acids. Nine of these amino acids are essential to our bodies – we can't produce them ourselves but have to get them from food. Some of them we need more of and some less.

This is the optimal distribution of amino acids:

Lots of leucine, lysine, and tyrosone, not a whole lot of tryptophan, and an average of the remaining amino acids. If a protein hits all of those minimum targets, it's called a complete protein.

Not that there's anything bad with a protein having a lot of tryptophan (it's quite a useful amino acid, I'll have you know) but generally if something has more in one amino acid, it'll have less of another.

Now let's have a look at how the different vegan protein powders stack up to this ideal distribution.

The best vegan protein powder #

So which one is the best?

First, before we answer that, it's worth keeping in mind that the difference between a bad protein powder and a good one will be minimal. You won't suddenly put on another kilo of muscle just because you picked one powder over another.

Second, when it comes to growing muscle the most important amino acid is leucine. It acts as a signal for the muscle protein synthesis9 (kickstarts the gainz). You'll need the other amino acids to be present, as building blocks, but they're somewhat secondary to this process.

With that in mind, we can see that hemp protein powder isn't all that good. It's not a complete protein and it's far from having enough leucine. There are better alternatives.

Soy protein is definitely a complete one. Just looking a these numbers it wins, hands down. I don't use it myself but not because of the fear mongering (no, soy won't give you manboobs and a limp dick). I simply dislike the consistency and taste – it's too muddy and sweet for me.

My personal favorite is rice and pea protein both! They mix very well with no clumping and have no nasty taste. The unflavoured variants are perfect for adding to smoothies and similar.

Further, if you look at their amino acid profiles, you'll see that rice is low on lysine, while pea has plenty of it. Pea on the other hand is low on tyrosine, which rice has much more of.

So I simply do the obvious – I buy a bag of each and I mix them. :)

Protein powder brands #

Next, which brand should you get?

Let me start by saying, as clear as I can, that more expensive does not equal better. There are some ridiculous claims out there but protein is protein – there's nothing magic about it. Just find one that tastes nice, is cheap enough to fit your monthly budget, and contains good protein.

I've personally tried many, many types and brands and these are my own favorites that I use:

Complete Vegan Blend – the well rounded one #

This is a mix of pea and rice protein, with a nice strawberry or chocolate flavour. I usually drink this one after lifting or if I feel like having a snack.

Pea protein isolate and Brown rice protein – the twins #

I try to always have a bag of these two at home, because they're part of my breakfast smoothie pretty much every morning.

If you use the links above to buy some protein powder, I get a small commission and it doesn't cost you anything extra. It's an easy (and free!) way to support Athlegan. As always, all the recommendations I give are my personal favorites and I'd give them regardless of any reward.

Have you heard of Clean Machine Green Protein? Apparently it's made from "water lentils" and has a really good amino acid profile.

#2 Tobias on 03 May 2018

Thanks for the tips, Chris! This sounds interesting and if their claims are true I'm getting myself some to try. :) I couldn't find the amino acid profile of their protein powder though so I wrote them and asked about that – will update here when/if I hear back.

#3 Chris on 03 May 2018

Ok great! Let me know what you find. Thanks for putting up valuable information on your site.

What about oat protein, it has the best taste and not even mentioned?

#5 Tobias on 04 September 2018

Oat protein should definitely be here! I'll update this list as soon as I have some more free time. :)

A research paper about vegan protein recently came out and in it they tested potato and corn protein. I didn't realize that those existed. Apparently corn protein has more leucine per gram than whey does. You only need to take in 20g of corn protein to get 2.7g of leucine. The paper is called "Protein content and amino acid composition of commercially available plant‐based protein isolates"

#7 Tobias on 05 September 2018

Oh, wow, that's super interesting! I knew that potato had a really good amino acid profile (being a complete protein) but I had no idea that corn was that good. Found the article now, so I'm adding that to my list of updates for this article. ;) Thanks, Chris!
