Ethical Consumption

You deserve more
from your protein source
And so does our planet.

Not everyone cares as much about our Earth or its inhabitants as much as perhaps you or we do, even though our survival as a species depends upon it.

But we believe that even small changes can have a huge impact, when done enough times, by enough people.

So, if you didn’t have to change anything other than the name on your protein bottle…

and that could make a huge difference in all our futures…

Wouldn't you make the switch?

Spacemilk is everything you’ve ever wanted in a protein – and in a company.

Why it matters...
No other protein on earth is as humane, or as gentle for our planet. Period.

A large part of how Spacemilk came to be has to do with our experiences with other brands. This may sound familiar:

You like everything about a protein shake, except it just has (any number vanity ingredients). Or, you know that because it's a blend of several incomplete proteins, it's not really complete and you don't feel great after it, but it's the least-worst animal-free option you can find for your stomach.

Maybe it's not bad, but you know when you put it in the recycling container that it's highly likely it's still just going to a landfill.

We've been settling for less for so long. Now, you have a better choice.

Message from Walter Ross, Founder of Spacemilk

“I want to live in a world which reflects the compassion of humanity. Any company is composed of people, but so much of those very human values can be lost along the way.

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.

While we are the first to pioneer this new category, I hope to soon see more companies adopt cell-based technologies and plastic-free packaging. To me, these are necessary small steps to solve the current and future global issues facing our species. The race is on– ad astra!”

Spacemilk News

Spacemilk is honored to be a 2023 Nominee for the Edison Awards in Innovation for Food and Agricultural Advancements.

It is our hope to bring clean, sustainable nutrition to every corner of our world and beyond, but that giant leap for mankind starts with the single step we take together, today.

  1. Why is Spacemilk right for me?

    With 25g of complete 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.

  2. 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.

  3. Is Spacemilk vegan?

    Yes! Spacemilk is neither animal- nor plant-based.

  4. Why should I have a Spacemilk subscription?

    There are a few reasons many customers prefer a Spacemilk subscription.

    • Our subscribers receive free shipping for the life of their subscription, as well as increased discounts: all subscription orders ship with free shipping for the life of the subsription, but in order to help you fully keep Spacemilk part of your daily routine, the second shipment also receives 5% off, and then the third and every subsequent shipment in the subscription receives 10% off.
    • Spacemilk is made in smaller batches to ensure purity; therefore, there is only so much Spacemilk available with each run. Subscriptions receive priority, and are the best way to make sure you never run out of Spacemilk.
    • Subscriptions are flexible in frequency and quantity, and the quantity discounts are in addition to subscription discounts.

    We know that making Spacemilk a part of your daily routine will help you feel great, and want to help you stay feeling that way!
