"My choice is spacemilk because of the minimal ingredient list and the amino acid ratios, it is by far the superior choice when it comes to protein supplementation"

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

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.

    Excellent product!

    Delicious taste without sugar or sugar alcohols! I am a sugar free guy, so I mix the chocolate mouses flavor with unflavored, and it's perfect. Having a handheld flother/ mixer is the best feature for this product! Spacemilk should offer them on their website. It made the product so much easier to prepare. Every morning I put a serving in my decaf coffee. In the evenings, I put a serving in a glass of unsweetened soy milk, and a tablespoon of peanut butter. My handheld mixer puts it all together and it's amazing! At 63 years old it's definitely helping keep my thirty something build!

    Thanks Space milk gurus!

    Great consistency and light tasting

    Space milk has great nutritional value and doesn’t have an overpowering taste.

    Great protein source

    This is so much better than whey and plant based.

    Yum!

    I just ordered 3 more bags of Spacemilk because my first bag is almost gone and I don’t want to run out. It’s so delicious!! Smooth, not gritty like some other brands, doesn’t upset my IBD stomach and tastes so good. I’m excited to try the vanilla now. Could you pretty please make a chocolate peanut butter flavor??
