Our Process
Cultivation
We start with baker's yeast and cultivate it in stainless-steel fermenters, feeding it simple plant-based sugars like molasses.
Isolation
Using mild heat and natural food enzymes, the yeast's own enzymes break down its cell walls, releasing the pure protein within.
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.
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.
