It’s tough to find KOS in Canada, but I finally got my hands on some to test and compare with other vegan protein powders.

The packaging and customer service are really good, so I had high hopes for it going into the testing.

But in order to take out personal bias, I test all protein powders with a mostly objective testing procedure.

Overall, KOS’ plant based protein powder scored okay, but ends up right around the middle on my best vegan protein powders comparison page.

Here’s a quick summary of KOS, I’ll go into detail below:

Now for the breakdown.

How Much Protein is in KOS Protein Powder?

My test starts with a simple calculation that looks at how much protein is in a serving, as well as how many calories are in a serving.

This is easy to calculate from the nutrition label:

At first 20 grams of protein seems like a good amount, but there’s 170 total calories. So only about 47% of the calories come from protein, which is low compared to other vegan powders (some are over 80%).

If you’re just looking for a general protein shake to get a bit of extra protein, that’s totally fine for you, 20 grams as a raw amount is decent.

But if you’re an athlete, or more specifically a bodybuilder, who is trying to cut, it’s not so great.

How Affordable is KOS?

Price is usually a factor when buying a protein powder, so I have an objective formula for that too.

Keep in mind that KOS is an organic protein powder, and those are typically more expensive than others.

KOS achieves a “price score” of 17.08 out of 25 (where 25 is as cheap as possible).

So it’s definitely affordable when compared to other vegan protein powders, even being organic, which I think is a positive aspect of this product.

How Do KOS Plant Based Shakes Taste?

Taste is probably the most important aspect of a protein shake.

If it tastes bad, you won’t want to drink it, and that defeats the purpose.

That’s why I have 2 scores that measure different aspects of taste.

The first is mixability. If a powder doesn’t mix well, you’ll have chunks or grains floating around in the shake, which generally detract from the overall taste.

To test this objectively, I mix a specific amount of almond milk with a measured amount of protein powder. Then I strain it, and weight the “clumps.”

In this case, here’s what my filter looked like:

It got pretty clogged, indicating that it really did not mix well.

After a few runs, the median weight of the clumps was 5 grams, which equates to a score of 9.375 out of 25. This is the biggest weakness of the products.

But on the other hand, the overall taste is largely determined by the flavor. The “taste” rating that I give to each protein shake is a subjective one that I give to each protein powder, although I try to be consistent.

KOS’ plant based protein powder has a really good flavor. I test it after filtering out the chunks, and would put it tied for the best of any of the 20+ vegan shakes I’ve tried.

This saves the overall taste of the shake. It’s not perfect because of the chalkiness/clumps, but it’s definitely drinkable and not much of a struggle.

Summary and Comparison to Other Vegan Protein Powders

Those are just about all my test results and thoughts on KOS.

If it’s convenient to buy for you, or you can get a good deal, I think it’s a decent option for vegans, especially if you’re just looking for a casual shake and aren’t an athlete tracking every calorie.

But while I wouldn’t recommend against buying it (as I have for some truly awful ones I’ve reviewed), there are others that I would recommend over it in different situations.

Here are the top 2 alternatives in my opinion:
