Why does my smoothie turn brown?

So, you just blended a smoothie… 

You threw in a couple handfuls of spinach, a banana, and a cup or two of mixed berries. Then you turned your blender on, waited a minute, shut it off, poured it into a glass, and… wait a minute.

“Why isn’t my smoothie… green… or beautifully purple?!”


Don’t be alarmed! Not every smoothie recipe will leave your glass a vibrant Instagram-worthy color. That doesn’t mean that you aren’t technically drinking a tasty smoothie. And if you added any leafy greens to it, you can still consider it a green smoothie — even if it looks more brown.

We call the drinks that we make “green smoothies” because each recipe includes at least a couple cups of leafy greens (spinach, kale, swiss chard, etc.).

We love leafy greens, and think that they are one of the most nutritious foods that exist. That’s why we recommend having at least one green smoothie a day! You may be thinking, “That’s nice, but why do mine never turn out green?”


Here’s a few reasons why green smoothies turn brown

  • Any type of berry was used in the recipe
  • The fruit used was a dark colored, or possibly red
  • It’s a recipe with beets
  • You forgot to add the leafy greens…oops!

Are brown smoothies as nutritious as green smoothies?

They sure are! No matter what color your smoothie turns out it will nourish your body as long as you’re using leafy greens and raw fruits/veggies.

    Had to laugh out loud at the “forgot to put leafy greens in the blender” line!

    Hi Christine! Are you asking how to purposely make them not green? If so, just add some dark berries!

    I often add natural fortifiers–Chia, Flax & Cacao–which give my Green Leaf Smoothie a Brownish hue !! 🙂

    Thanks for sharing Brian! Yes, chia, flax and cacao can change the color as well. 🙂

    Being a diabetic my nutritionist told me stop drinking smoothies because they have to many carbs in them. With all the fruit that they have in them. How can I make green smoothie with less carbs and still taste good?

    I make green smoothies and they are always brown…about 10 minutes later they turn a bright green. Do you know why this could be happening?

    Hey Paige,

    We have honestly never heard of that happening before, so this is new to us. Normally when you first make the smoothie it is bright green and when you stick it in your fridge it will turn a brownish color, but never the opposite.

    When I make my smoothie in the morning (spinach, banana, lots of frozen blueberries, flax seed, amla powder), it is a brilliant blue/purple. But by 3:00 break it turns a mud brown. (In the morning it isn’t brown). Does that mean the ‘good stuff’ is going through oxidation? Is it more harmful or less nutritious?
