Yeast Protein Powder

This product is a new type of protein that's innovative and environmentally friendly. It's extracted by fermentation and, unlike animal and plant proteins, is not influenced by climate and environment.

Yeast protein has a protein level that's similar to whey and pea protein powders (80%), with a complete amino acid profile and high Branched Chain Amino Acids (BCAA) content that's suitable for muscle growth and repair.

It also has a protein digestibility score (PDCAAS) of 1 - that's as high as milk proteins and higher than plant protein powders.


  • Complete protein with similar protein content to whey and pea
  • Contains all essential amino acids and high in BCAAs for muscle growth and repair
  • Digestibility PDCAAS score is the same as whey and higher than plant based proteins
  • Slow digesting to provide amino acids to the body steadily
  • Source of dietary fibre for gut health
  • Animal free, GMO free, pesticide free, gluten free, dairy free, and allergen free
  • Eco-friendly and sustainable source of protein
  • Good alternative to plant and animal based proteins
  • Note, the vitamin B12 content in yeast protein is neglible.

Taste and Texture

Yeast protein has a taste and texture that are both very similar to pea protein.


Protein digestibility is a measure of the proportion of protein that is absorbed by the body. In the below chart we are comparing three protein types (pea isolate, whey concentrate, and yeast) as all have similar 80% protein levels.

PDCAAS chart for pea vs whey vs yeast protein powders

The Protein Digestibility-Corrected Amino Acid Score (PDCAAS) is a rating that determines the bioavailibility of a protein. Biological value is a measure of the proportion of absorbed protein that's retained for growth and maintenance. 

The PDCAAS score for yeast protein is the same level for whey and is higher than pea protein.


Yeast protein is very sustainable and its manufacture follows a circular economy model.

Sugar cane and molasses from beets are the source of nutrients for the yeast, and in turn waste from the industrial production of yeast is used as organic fertiliser for the production of crops.

Yeast protein is made from fermentation so it's not influenced by environment. It's extracted in short production cycles that are highly effecient compared to plant and animal sources which have longer breeding cycles.

Yeast vs Pea Protein

Now that we know all the benefits of yeast protein we can address which is better - yeast or pea?

One serving of our yeast contains ~134 calories and ~24.8g of protein. One serving of our pea contains ~111 calories and ~25 grams of protein, so both have similar protein levels and yeast has higher calories. Be mindful that yeast contains some fibre which contributes to the calorie count.

Both are also high in L-leucine. Leucine is one of three branched chain amino acids and is primarily involved in muscle protein synthesis for muscle growth and recovery. It also contributes to the regulation of blood-sugar levels, growth hormone production and would healing. 

The leucine content of yeast is about 7.5g per 100g, and in pea about 7g per 100g, so both are similar and both are good for muscle development. Both also have a similar amino acid breakdown but yeast is slightly higher in BCAA content.

As yeast is a new protein powder there is no data regarding how it would compare to pea when taken post workout, but there is research that suggests pea is as effective as whey in supporting muscle gain. Another study here found that pea protein vs whey protein taken post exercise both yielded positive results with no difference between the group taking pea and the group taking whey. Therefore we predict that it will be similar with yeast due to the similar amino acid profile and protein level that exists between yeast and pea. 

Both protein powders are slow digesting and yeast has a slightly yeasty smell whereas pea is slightly grainy in texture. We recommend trying sample sachets first if unsure.

I normally avoid sucralose as a sweetner but I was interested to try a yeast protein. Retains a slight yeasty taste. I often use it with another protein and it works fine.

My favourite vegan protein powder that I have tried, good flavour and great price.

Does tend to settle at the bottom of a cup a lot more than whey protein, easily solved by giving it an extra shake as you consume.

Love it, very fine, smooth texture and neutral taste 👍

Less gritty than pea, hideable taste. unflavoured works well with fruit.

Somehow slightly savoury in taste. If adding to a smoothie use no more than 1 scoop. With me having a vegetarian diet, it has been great getting the extra protein I need

Best texture of all the vegan protein powders I’ve tried, really fine so mixes in well. I got the unflavoured protein, does have a yeast-y taste that is easily covered up with frozen berries and a little coco powder. Easy on the gut.

Yum and not sticky, slightly chalky consistency but better than other plant based proteins I’ve tried :)

Mixed in water very easily, tastes great and no stomach issues after.
This seems to work very well for me

Tastes a bit savoury but it's the best protein powder I've had so far. Highly recommend

Never had an animal-free protein that was as easy to dissolve. Minimal grainy texture, but much nicer than pea or, god-forbid, rice. Doesn't reach faba bean protein levels of smoothness, though. Has no yeasty taste except for when you burp on it, you get a mild whiff of vegemite. The choc caramel is pretty intense, but I'm mixing 1 serving of it with 1 serving of faba bean banana protein in an XL shaker now, and it's brilliant - best of both worlds!

I'm not sure if this is Yeast or Weet-Bix
