A Detailed Review of Nuzest Clean Lean Vegan Pea Protein Powder


Flavors: Several, including unflavored, vanilla, chocolate, coffee

Nuzest was the 23rd vegan protein powder that I tested on my quest to find the best vegan protein powder.

I can sum up Nuzest’s protein powder really easily: It would be THE best overall, except that it’s extremely expensive.

If money isn’t a factor for you, then it’s probably the best option you’ll find.

Otherwise, if budget is a concern for you, there are better “value” options.

In this review, I’ll break down how Nuzest scored based on my standardized testing procedure.

Nutritional Value and Protein Content

The first thing I always look at is how much protein is in the powder?

Protein powders should ideally have as much protein as possible, with as few calories as possible.

So I created a nutrition score that compares the percentage of calories that come from protein to the highest amount I found in any powder (which was 90% of calories). Here’s the simple formula:

Protein powder nutrition score formula

In a serving of Nuzest’s vanilla protein (varies a small amount based on flavor), there are 20 grams of protein and 90 calories.

Plugging in that data to the formula, and we get a price score of 24.69 out of 25. That’s a perfect score when rounded up.

In plain English, Nuzest has as much protein per calorie as you’ll find in any powder.

This is mainly due to the simple ingredients list. For example, here’s the ingredient list for the smooth vanilla flavor:

Pea protein isolate, Natural vanilla flavor, Thaumatin

Thaumatin is a low-calorie natural sweetener. Personally, I much prefer the taste of it to stevia, which almost every other powder uses.

Finally, one last note is that Nuzest uses European pea protein isolate. There have been some concerns over heavy metal contamination in protein powders lately, mainly those sourced from China (which most companies use).

So if you wanted to be on the safe side, Nuzest is one of your few options that sources their pea protein from elsewhere. This probably adds to the cost of the product.

Pricing of Nuzest

In the summary at the beginning, you may have seen that Nuzest had a price score of 0 out of 25.

In other words, it’s the most expensive vegan protein powder per 100 grams that I’ve come across.

The average score is around 15 for reference.

I don’t have much else to say, only you know how important budget is to you.

How Well Does Nuzest Mix?

The third main component that I test is mixability.

I follow the same procedure for every powder, to ensure that they are compared fairly:

  1. Add 450 mL of unsweetened almond milk to shaker bottle.
  2. Add 35 grams of protein powder.
  3. Shake for 45 seconds.
  4. Pour shake through a fine strainer to remove clumps (and weigh them).

The mixability score is then calculated with this formula:

Protein powder mixability score formula

Nuzest mixes really well. There’s a bit that sticks to the sides of the bottle, but no actual “clumps” (more like foam on the sides of the bottle).

Here’s a picture of the strainer after I poured the shake through it:

You can see that other than a few specks that weigh virtually nothing, it’s empty.

With 0 grams of clumps, Nuzest gets a perfect mixability score of 25.

Does Nuzest Pea Protein Taste Good?

The final thing I test is taste, which is the only area where my personal opinion is really involved.

I try to be consistent as possible, but of course you may rate certain tastes differently than I do.

Here were my main takeaways from my tests (I test multiple shakes):

In short, it’s arguably the best tasting one that I’ve tried so far.

I debated whether to score this 22 (like some of the other best ones), or a perfect 25.

Ultimately, I think Nuzest tastes about as good as you can get for a protein shake, so I gave it the only perfect 25 of any powder so far.

Summary of My Nuzest Pea Protein Review

If cost isn’t too important, Nuzest is likely the best overall vegan protein powder for you.

However, if overall value for your dollar is more important to you, consider more affordable, but still high quality proteins like PlantFusion. Here’s my PlantFusion review if you’d like to see how it compares.
