WHY SPACEMILK?
Spacemilk fuels human performance with clean, complete, future-ready protein. We make nutrition effortless—so people can focus on living their lives, not managing their diets. The way we eat today is too complicated. Too processed. Too toxic. Nutrition should be easy. No allergens. No fillers. No nonsense. Easy to mix. Easy to digest. Easy to love. This isn’t just a shake. It’s the future of food.
Space Grade Protein
Spacemilk is naturally designed to be the best —better than whey, pea, or soy. Derived from non-GMO baker’s yeast, Spacemilk’s protein has more complete protein per gram and no allergens, pesticides, or animal products. That means your body gets more of what it wants, and less of what it doesn’t. Spacemilk is also the same acidity as water, so it mixes smoothly and won’t leave you bloated or uncomfortable. Even better, this revolutionary clean and sustainable food source can be grown anywhere– even in Space!
Combined, these traits are what make our protein Space Grade:
Perfect for every body on Earth, and in Space.
A New Hope
Spacemilk is a game-changer in the world of protein. It belongs to a new category called “single-cell protein,” made from single-cell organisms—the most efficient and renewable sources of protein on Earth.
Our protein comes from non-GMO baker’s yeast, a member of the fungi family, like mushrooms. But unlike mushrooms, which are complex, baker’s yeast is a simple, single-celled organism that’s easy to grow. People have used baker’s yeast for thousands of years, but until now, it wasn’t used as a major protein source because its cell walls are hard for us to digest.
Thanks to new technology, we can now separate the protein from the yeast cell walls. With just water and electricity, we extract, wash, and purify the protein until it’s exceptionally clean and pure. It’s then pasteurized, dried, and packaged as Spacemilk.
This process is one of the most sustainable and environmentally friendly ways to create protein. And as it happens, the protein from non-GMO baker’s yeast is a perfect match for human nutrition.

Sustainability
Spacemilk’s single-cell protein redefines sustainability in food. Made from non-GMO baker’s yeast grown in water, our protein produces up to 97% less CO2 than whey and 40% less than even soy. It also uses significantly less land, water, and nutrients—while being completely free from pesticides, runoff pollution, and GMOs.
Our process leaves a minimal environmental footprint, producing a pure, animal-free protein that’s best for you and best for the planet. Whether you follow a traditional or vegan diet, Spacemilk offers a cleaner, more digestible option that drives the future of sustainable nutrition.
Allergen Free
Spacemilk's protein is derived from non-GMO baker's yeast and is allergen free. To be extra clear, Spacemilk is: gluten free, dairy free, soy free, and free of all major allergens.
What about a yeast sensitivity?
1. While Spacemilk is made from yeast, all yeast cell wall material is fully broken down, filtered, and removed, leaving only protein, fats, and a tiny amount of flavor and aroma. This means it’s not like active or inactive yeast, so most people with yeast sensitivities should be fine. However, if you have specific concerns, check with your doctor first.
2. True allergies to baker’s yeast are extremely rare. Often, yeast sensitivities are actually reactions to molds or byproducts in fermented foods. Our process includes multiple rounds of washing and filtering, which would remove these byproducts (if any) to create an ultra-pure, allergen-free protein.
