Our Process

Cultivation

Cultivation

We start with baker's yeast and cultivate it in stainless-steel fermenters, feeding it simple plant-based sugars like molasses.

Isolation

Isolation

Using mild heat and natural food enzymes, the yeast's own enzymes break down its cell walls, releasing the pure protein within.

Purification

Purification

We use a high-speed centrifugal process to separate the protein, then washed, pasteurized, and dried into a pure powder.

Designed for Every Body

Innovative Nutrition, Made for You

With a perfect 1.0 PDCAAS score, our yeast protein isolate matches the nutritional quality of whey and provides all nine essential amino acids. It’s the complete, clean protein your body needs to build, repair, and thrive.

Created with a neutral pH of ~7, Spacemilk is exceptionally gentle on your digestive system. Get powerful nutrition without the bloating or discomfort common with other protein supplements.

Spacemilk is a slow-digesting protein that provides a sustained release of amino acids to help curb hunger and keep you focused for hours. It’s the ideal choice for weight management without nutritional compromise.

We are 100% animal-free, but our commitment goes deeper than traditional plant-based proteins. Our clean fermentation process uses no arable land, creating a truly compassionate protein that is better for you and every living thing

Designed to be truly hypoallergenic, Spacemilk is naturally free from dairy, soy, gluten, and all major allergens. It's a safe, powerful, and reliable option created for even the most sensitive dietary needs.

Designed for Every Body

Our protein begins with a strain of baker’s yeast (Saccharomyces cerevisiae), the remarkable microorganism that has been a trusted part of our food system for thousands of years in bread and beverages. Instead of a field, we cultivate our yeast in a pure, controlled environment similar to a craft brewery, feeding it simple nutrients like molasses from sugar beets. This clean fermentation process gives us complete control over quality, ensuring our source is free from the pesticides, heavy metals, and pollutants often found in traditional agriculture.

From there, we transform the whole yeast into a pure protein powder. We use gentle heat and the yeast’s own natural enzymes to unlock the valuable protein from within the cell. Next, a high-speed spinning process carefully separates the pure protein from everything else. This is what makes it a protein ‘isolate’—we remove the yeast cell wall and other components, leaving behind a smooth, neutral-tasting powder with no active or inactive yeast. The result is pure protein crafted with scientific precision.

    SINGLE Ingredient Protein + Doesn't bloat me

    Been looking for a protein powder that isn't whey but still has the complete amino acid for a while now. This one takes the cake. Not only is the label literally one ingredient, but it is the first protein powder that doesn't bloat me at all. I have had a double serving before working out and felt perfectly fine!

    Exactly what I wanted—no weird taste!

    This one’s perfect if you don’t want flavor taking over your smoothies or recipes. I use it in everything—smoothies, soups, even baking—and it doesn’t change the taste at all. Sometimes I just shake it with water or mix it into coffee if I’m in a rush. No stomach issues, no chalky texture, nothing weird. Just clean, simple protein that actually mixes well.

    Hooked--All Flavors!!!

    Tremendous product!!! LOVE the monkfruit sweetener so I can enjoy the to die for chocolate without guilt. Just tried vanilla in BamNut milk--yum yum!! And mixed the unflavored in a watermelon/cucumber smoothie to make a complete healthy meal/drink! Versatile, DELICIOUS and feels clean and healthy. Just make sure you have air tight pouch for storage because their resealable bags are the only thing that needs improvement. Highly recommend--enjoy! Thank you SpaceMilk--let's get some recipes!?

    Excellent Product

    I am extremely pleased with Spacemilk. It mixes well, has no taste, and keeps me full well into lunch without making me feel bloated. I also greatly appreciate that it's clean and I dont need to worry about heavy metals. It is slightly messy, as it is very powdery, but I've learned how to contain it better. I won't be going back to pea protein...Spacemilk wins by a longshot.
