DESIGNED FOR THE HUMAN BODY.
PROTEIN SYSTEM
The foundation is a novel Yeast Protein Isolate, providing 20g of complete protein in just 100 calories. It achieves a perfect 1.0 protein quality score (PDCAAS), matching whey for quality, and delivers all nine essential amino acids to optimally support muscle synthesis and recovery.
TEXTURE & FIBER SYSTEM
A smooth, satisfying texture is achieved with a blend of functional, plant-based ingredients. Depending on the flavor profile, the formulas use either Acacia Gum for its prebiotic benefits or Konjac Gum for a richer, creamier mouthfeel. Every formula includes hexane-free Sunflower Lecithin to ensure a perfectly smooth, clump-free mix.
FLAVOR SYSTEM
A zero-calorie, zero-sugar system provides a clean, natural sweetness. The core is a breakthrough blend of Organic Monk Fruit Extract and Thaumatin, a protein-based sweetener from the Katemfe fruit. This is rounded out with clean Organic and Natural Flavors and a touch of Salt to create a delicious taste without any sugar alcohols or blood sugar spikes.
OUR INGREDIENTS
Every ingredient in Spacemilk was chosen after months of research, countless iterations, and an absolute refusal to compromise on purity, performance, or ethics.

Best protein powder out there!
I recently tried the Spacemilk vanilla protein, and I must say, I’m really impressed!!!. It's vegan and super light, which made it a great option for my post-workout shakes. I mixed it with water, and the taste was smooth and pleasant... not overly sweet, just the right amount of flavor. The protein blend feels really complete, providing everything I need in one scoop.

This has been such a game changer in my household. If i’m in a rush i throw a scoop in my coffee! if im having a smoothie i drop a scoop in the blender and it doesn’t over saturate any natural flavors! I even drink it by itself in my hydro flask full of water. It’s made consuming protein so much easier and doesn’t upset my stomach due to whey. 10/10 would recommend to lactose intolerant folks and anyone who’s looking to try a natural non animal protein!

The only protein powder that doesn't upset my stomach or cause bloating. I mix the vanilla in with my coffee and have a delicious protein latte. Love this stuff! Thank you for creating such an amazing product. It is not only better for my body, it's also better for the planet.

I love weightlifting but it’s hard to hit my protein goals as a longtime vegan. Since I started using Spacemilk the results are undeniable. It improves my performance, makes me feel better, and has zero bloating or weird stomach feelings. Absolutely recommend.

I absolutely love the unflavored spacemilk. I've been a customer for years. It's the only protein powder that doesn't make me feel nauseous. You can pair the unflavored with anything and cannot taste it. If you have any issues with other protein powders, try this. Plus they have great customer service.
