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.

How much Spacemilk should I take per day?

Follow standard protein recommendations of 0.8-1g per pound of body weight from all sources. Most people use 1-2 servings of Spacemilk daily as part of their total protein intake. The founders use 3-4 per day, sometimes more.

No. Spacemilk contains no artificial flavors, sweeteners, colors, or preservatives. All ingredients are natural or organic, including natural vanilla and chocolate flavors.

What can I mix Spacemilk with?

Spacemilk mixes well with water, plant milk, dairy milk, or can be added to smoothies, coffee, oatmeal, baking recipes, and other foods. Easy simple smoothies are frozen strawberries, water, and vanilla shake, or frozen bananas for chocolate mousse.
