LeanFit Complete Green Vegan Protein Review

leanfit vegan protein powder review summary

Flavor: Vanilla

(See pricing in store)

This is a vegan protein powder that’s only available in Canada, just like Kaizen and Canadian Protein.

I hadn’t heard of LeanFit before stumbling upon it at Costco.

Since I generally trust the quality of their products, I picked up a bottle of LeanFit Complete Green so that I could review it.

As I do with all my vegan protein powder reviews, I’ve broken this up into 4 sections, each with a score out of 25 (where a high score is always better).


The simplest place to start off when judging a protein powder is nutrition.

Since the most important thing that the vast majority of people are looking for is protein, the “nutrition score” that I calculate evaluates what percent of the calories come from protein:

You can see my testing methodology outline to see where this formula came from if you’re interested.

But all you need to know is that the formula outputs a number from 0 to 25 for all protein powders.

A score of 0 indicates that a product has fewer calories coming from protein than almost all other products. And a score of 25 means that the product has just about as high a protein percentage as possible.

We can get the data from LeanFit’s nutrition label:

With 19 grams of protein (76 calories), and 110 total calories per serving, LeanFit gets a nutrition score of ~19.

In practical terms, that means that it has a higher protein content than average, but that there are still other vegan protein powders out there that contain a higher percentage of protein.

If maximizing protein while minimizing total calories is the most important thing you’re looking for, there are better options for you.

Otherwise, LeanFit has an adequate nutrition profile for most people.

Let’s take a quick look at the ingredients list before moving on:

  • Vegan Fit Plant Protein Blend (Pea Protein, Hemp Protein, Flaxseed Powder, Brown Rice Protein, Chia Seed Protein), Inulin, Natural Vanilla Flavours, Monk Fruit Extract, Sea Salt, Protein Digestive Enzyme, Xantham Gum, Stevia (Leaf, Extract)

It has a diverse blend of vegan protein sources, and like most vegan powders, it’s sweetened with stevia.

The most interesting part is that it includes protein digestive enzyme.

Several people have told me that they’ve tried vegan protein powders before, which caused them to bloat and have gas.

Digestive enzymes could help reduce or eliminate any digestion issues.


You can find LeanFit in 2 main sizes:

  • 454 g / 1 lb
  • 1.02 kg / 2.2 lb

It’s much cheaper at Costco than Amazon, but you need to have a membership, and they don’t always have both sizes or even any in stock.

In order to compare the price of vegan protein powders fairly, I look at the price per 100 grams of the size closest to 1 kg, which is a size most manufacturers sell.

When a protein powder is only sold in Canada, I have a price score that is adjusted for Canadian prices, shown below:

pricing score formula

It takes the price per 100 grams and spits out a number from 0 to 25 for each protein powder.

A score close to 0 means that a product is expensive, while a score close to 25 means that it is cheap.

In this case, we get a price score of 18.4.

That’s pretty cheap compared to other vegan protein powders in Canada.

Keep in mind that I used the Amazon price because that’s the most accessible. If you happen to have a Costco membership, the price score works out to 24.36, which is about as cheap as you can get.


The mixability score tells you how well a protein powder mixes under pretty standard conditions.

Again, it’s a score out of 25, where 25 means that it mixes perfectly, and a score of 0 means it’s a disaster.

I use the same procedure to test every protein powder:

  • Add 450 mL unsweetened almond milk to a shaker bottle
  • Add 35 grams of protein powder
  • Shake for 45 seconds
  • Filter out the remnants (clumps) using a strainer and weigh them.

Then the amount of remnants goes into this formula to output a score from 0 to 25:

LeanFit Complete Green mixes really well, as can be seen in my strainer picture below:

There was only 1 grams of remnants, but if I had a more precise scale, I’m confident that it’s under that and was just rounded up.

With 1 grams of remnants, LeanFit gets a mixability score of 22. That’s very good, and means that with a standard shaker bottle, you’ll barely notice any clumping.


Last up is taste, which might be the most important part of a protein shake, but unfortunately there’s no objective way to measure.

The best I can do is try to be consistent with taste scores and give detailed reasonings for the scores.

I assign scores based on this table:

Taste Score Meaning
25 Amazing, would drink for enjoyment alone.
20 Very good.
15 Drinkable, not really good or bad.
10 A bit of a struggle to get down
5 Quite bad

The flavor is good, and there’s virtually no chalkiness.

The texture is good overall and there’s no significant aftertaste.

I read other reviews that said it was a bit too sweet, but it was just about perfect to me.

Of the 20 protein powders I’ve tried, this was one of the best.

Based on all that and the chart, I assigned a taste rating of 22.

Summary and Overall Review Impressions

LeanFit Complete Green has a lot going for it for Canadians. Based on its score, it’s one of the best vegan protein powders for Canadians.

If you have a Costco membership, it’s as cheap as you’re going to find here. If you don’t, the price is still reasonably cheap, although there are a few cheaper options if that’s important to you.

The mixability and taste are both excellent, among the best of all the vegan protein powders I’ve tried.

As far as protein content goes, it’s above average, although there are some others options that have more.

LeanFit definitely could be the best option for you depending on your individual preferences. It’s a solid choice in any case, I don’t think anyone would be too dissatisfied with it.
