Your protein stops working an hour after your shake.
Most protein hits fast and fades just as fast, leaving you running on empty an hour later. A quick spike, then nothing. It's not you. It's how fast that protein leaves your system.
Spacemilk is different. Its protein digests slowly, releasing amino acids in a steady stream instead of a quick spike and crash.
That means lasting fuel through the morning, between meals, or overnight, plus a steady supply of amino acids to support muscle recovery as you go about your day. No jitters, no crash, just protein that keeps up with you.
Your gut isn't being dramatic. Your protein is.
Whey is made from dairy, and most adults can't fully digest dairy. Even if you can, the lactose and casein give your gut a hard time. Switch to pea or soy and you trade one problem for another, both are high in FODMAPs that ferment in your gut and cause gas, bloating, and that heavy feeling that sits with you for hours.
It's not your stomach. It's what you're putting in it.
Spacemilk is grown from yeast. No dairy or lactose, no plant fibres, no high-FODMAP ingredients. There's nothing in it to ferment in your gut and leave you puffy and uncomfortable. Just clean protein that's gentle on digestion, every single day.
You didn't fail at protein. Protein failed you.
Most people who give up on protein shakes don't give up because they stopped caring. They give up because the discomfort isn't worth it, or because the shake never seemed to do much. At some point it just stops feeling worth the effort.
You don't need to give up on protein. You need a protein your body can actually use.
With a perfect 1.0 PDCAAS score and all nine essential amino acids, Spacemilk matches whey and egg for protein quality, without the dairy. You get 20g of complete protein in just 100 calories per serving. Everything your muscles need to build, repair, and recover.
Most people have no idea what's actually in their protein.
Most protein powders use xanthan gum as a thickener. Xanthan is a known gut irritant that ferments in your digestive system and is one of the most common hidden causes of bloating people never trace back to their protein.
Many plant proteins are grown in soil, and soil carries lead, cadmium, and arsenic. When you concentrate plant protein into a powder, everything in the soil concentrates with it.
Spacemilk is grown through fermentation, not soil, and every batch is independently third-party tested. Below Prop 65 limits, the strictest heavy-metal standard in the US, and non-detect across a 77-pesticide panel.
Good news. It doesn't have to be this way.
No bloat. No gas. No spike and crash an hour later. No giving up halfway through a bag because your stomach can't handle it.
Spacemilk isn't whey and it isn't a plant protein. It's the world's first protein from non-GMO baker's yeast, made by fermentation. That makes it 100% vegan and free from all 9 major allergens, with no artificial flavors or sweeteners. And because it's so pure, it mixes smooth and creamy, no chalky, gritty plant-protein aftertaste.
10,000 people have made the switch. Most of them say the same thing: they just wish they'd found it sooner.
