Designed For Every Body
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.
Zero Bloating
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.
A Perfect Protein
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.
Lasting Satiety
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.

Why We Built Spacemilk
"I created Spacemilk to change the ingrained practices in the nutrition industry. With Spacemilk, I see a future where feeding everyone doesn’t necessitate the destruction of our environment. I see a future free from scarcity, where each person can have the exact nutrition they need to thrive, not just survive. With cell proteins and similar technologies, the future is bright and the possibilities are endless."
-Walter Ross, Spacemilk Founder
