  1. What is Spacemilk?

    Spacemilk is the first complete and highly digestible non-GMO cell-based protein. Derived from baker’s yeast, the protein in Spacemilk is complete and hypo-allergenic. Spacemilk original protein is combined with fiber, probiotics, monkfruit, and a touch of salt.

  2. What makes Spacemilk different from animal or plant-based alternatives?

    Its nutritional value is comparable to animal-based whey, making it a better choice than plant-based proteins, yet is vegan. It’s significantly more sustainable - using less water, land, and other resources - than plant- or animal-based options, which is great for our planet.

  3. What is Spacemilk made from?

    Spacemilk is a cell-based protein derived from yeast protein isolate. It also contains organic Sunfiber™ which is the best hypoallergenic fiber ingredient and Lactospore™ which is a cutting-edge probiotic to support your digestive system. 

  4. Is Spacemilk vegan?

    Yes! Spacemilk is neither animal or plant-based.

  5. Is Spacemilk free of allergens?

    Yes. The purification process isolates the protein from the cells using only water and electricity. This means that, unlike other protein sources, Spacemilk is free of any solvents, chemicals or undisclosed ingredients.

  6. Why is Spacemilk right for me?

    With 25g of protein, 3g of soluble fiber, and 1 billion CFU of probiotics per serving, Spacemilk is right for anyone who is looking to increase their daily protein intake while being kind to their digestive system.

  7. How do I use Spacemilk?

    Spacemilk can be blended with 8oz of your preferred milk. It’s highly soluble.

  8. When will I know if Spacemilk is working?

    We recommend giving it two weeks, but you should begin to see improvements to your digestion and overall well-being from the first day.

  9. Do you offer samples of Spacemilk?

    Instead of small samples, we offer a 30 day risk-free guarantee. We are committed to reducing waste and being eco-friendly, and current options for samples do not allow for that. However, if you don’t love it, we have a no-hassle, risk-free guarantee. 

  1. What makes Spacemilk sustainable?

    The cell protein that’s in Spacemilk produces 85-97% fewer greenhouse gasses than whey protein. It’s grown in water so it uses far less land than both animal- and plant-based proteins (even plant-based proteins require sprawling farms, long periods of time, and more inputs from all over the globe). The water used to produce Spacemilk is infinitely recyclable. Lastly, our aluminum packaging is actually recyclable, unlike most plastics, and we don’t include single-use plastic scoops in our bag to reduce our impact on the environment.

  2. Why is there no scoop in my bag?

    We don’t include single-use plastic scoops because we’re committed to being sustainable and eco-conscious, starting with our packaging. We invite our customers to enjoy Spacemilk by using their own ⅓ cup measuring cups. However, we do offer an optional metal, fully reusable measuring cup at checkout for your convenience.
