Kaizen Naturals Vegan Protein Powder Review


(Click to see in store)


Flavors: Vanilla, Chocolate

Kaizen is a Canadian-based supplement company, mostly known for their whey protein powders.

However, they do have one vegan protein powder, which I gave a try (chocolate) in order to review.

Just like every other review on this site, I’ve broken it down into the 4 main factors I judge protein powders by. All scores have been calculated whenever possible in order to minimize any personal bias.


The nutrition score is based off of one factor: protein content.

Basically, when comparing calories from protein to the total calories in the powder, the higher the ratio, the higher the score.

That’s captured in this simple formula.

Protein powder nutrition score formula

Here is the Kaizen powder nutrition label that I used to calculate the nutrition score here:

If you plug everything in, you get a nutrition score of 17.

For convenience, let’s take a quick look at the ingredients list:

Plant protein blend (pea protein, organic pumpkin seed protein, sprouted whole grain brown rice protein, chia seed protein, organic sprouted quinoa), Inulin, Natural flavours, Dutch cocoa powder, Stevia leaf extract, Xanthan gum, Tapioca, Sunflower oil, Sunflower lecithin, Sea salt.

It’s a short list without any ingredients that would cause alarm.


In order to evaluate the cost of a protein powder fairly across all powders, I look at the size closest to 1 kg/2.2 lbs.

If the powder is widely sold on Amazon or a similar site where it’s easy to get free shipping (as it is in this case), no shipping cost is applied.

I simply plug in the price per 100 grams into the following formula to get a score.

Protein powder pricing score formula

Currently, there’s only 1 size that you can buy this powder in, which makes it easy to choose the right one to compare:

Size Cost (CAD) Cost per 100 gram

840 g / 1.85 lb



After plugging in the cost per 100 grams (in USD) into the formula, Kaizen’s vegan protein powder gets a price score of 16.

In other words, it’s pretty expensive for the amount that you get compared to most other proteins.

If cost is a big concern for you, you might want to keep looking.


A good protein powder should mix completely in most liquids.

To test this, I weigh the amount that doesn’t dissolve after being thoroughly shaken in a shaker bottle.

To get relatively consistent results, I follow these steps:

  1. Measure the scoop weight
  2. Add to 450 mL of almond milk
  3. Shake vigorously for 30 seconds in a standard shaker bottle
  4. Pour out the liquid, then scrape and weigh the remnants

The weights collected are then plugged into this formula to find a score:

Protein powder mixability score formula

Kaizen does not mix well. In 2 separate trials, there were 9 grams and 7 grams of remnants respectively.

A remant weight of 9 grams yields a mixability score of 3.125, meaning that it's worse than almost every other protein powder.


I leave taste for last because it is admittedly subjective.

I’m not too picky when it comes to protein powders, so if you think that you’re a little more particular than most, take a few points off my scores in all cases.

Here are my general guidelines:

Taste Score Meaning


Amazing, would drink for enjoyment alone.


Very good.


Drinkable, not really good or bad.


A struggle to get down



I gave this protein powder a 20.

It’s not something you’d drink for enjoyment all the time, but I’m more than happy to drink it to get the protein from it.

There are 2 things in the taste that really stood out for me:

  1. It has a strong “chalky” taste to it - This is a common trait to protein powders, but I felt it was a bit more pronounced in this case.
  2. It’s a bit too sweet - Not to a degree that it’s terrible, but ideally I do prefer protein powders that are a bit less sweet.

Summary and Overall Impressions

Kaizen’s Naturals vegan protein powder is one of the weaker protein powders I've tried when it comes to the overall score.

It tastes pretty good, and the nutritional profile is decent, but it's expensive and mixes poorly.

In most cases, I think you'll be able to find a better option. However, if you can get it on a good deal, or it's your only option, it's worth a try.
