Yeast Protein Powder | 30g Complete Protein

Most people describe the flavor as something mild, like an oat or nut milk. Our current recipe is ‘Unflavored’ - we like to call it ‘naked’ - it’s simple. If you generally like things sweeter, we recommend adding monk fruit or stevia.

We like unflavored because it's versatile -- add fruit, maybe peanut butter, maybe cacao powder, or even bake with it -- It'll taste great any way you like it; even in water.

Most people under-estimate the protein they should consume in a day in order to thrive.

The American nutrition guidelines are only ‘enough to survive’. Most professionals agree that active bodies need about .8-1g of protein per pound of body weight. That's about 120-150g of protein for a 150lb person.

We help you achieve this goal in an easy way; with a protein you can use daily.

ProteinRx is for anyone who wants more protein without dairy, lactose, soy, pea protein, or common allergens.

Made from yeast protein, it’s a complete protein that works well for vegetarian, vegan, and sensitive-stomach diets.

Our founder created it to help his grandmother maintain strength, give his vegetarian wife a better option, and support aging parents with simple daily nutrition.

You get 30g of protein and no sugar in a clean, easy-to-use blend.

Our protein is a simple 1-ingredient protein powder extracted from the protein within baker’s yeast cells (saccharomyces cerevisiae).

This single-cell protein isolate is unique in that it doesn’t involve plants OR animals -- in fact, it comes from the fungal kingdom.

You get a complete protein with an amino acid profile similar to whey, without the allergens, and without using as much water, land, or pesticides.

Without plants or animals!

Our protein comes from fermented yeast, fermented in tanks similar to those used for beer brewing. The yeast cells are broken apart and the protein is mechanically separated.

Trace amounts — far less than most protein powders. Every batch is third-party tested. Our lead content is 0.077 ppm, compared to 0.5–0.6 ppm typically found in pea and rice proteins. That's roughly 7x lower.

Clean protein, verified by an independent lab. No guessing.

Yeast Protein has an Amino Acid profile similar to Whey, and both have a PDCAAS score of 1.0

(Protein Digestibility Corrected Amino Acid Score) is a measure of how good a protein is for you, and 1.0 is the highest possible score, meaning it's excellent).
