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.

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.

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.
