Yummy Fruit and Spinach Protein Smoothie

I know, I know, it doesn’t sound yummy, but this is one of my favorite ways to get down a serving of leafy green veggies. As I’ve gotten older I’ve developed more of a taste for vegetables, but I still have trouble getting as many as I should. So last year while I was obsessed (?!?) with watching Thintervention, this shake that Jackie Warner made really caught my attention. And it’s really good!

Fruit and Spinach Smoothie

See all those little green flecks in there? That’s frozen spinach. If you do a really good job blending it up, you don’t really notice it. (If you don’t, it can be a little stringy and get caught in your teeth.) Here are all the add-in ingredients I use in the smoothie.

Smoothie Ingredients

I got all of these from my local GNC – nothing special ordered or hard-to-find.  The whey protein comes from milk, and the carnitine, glutamine and BCAAs are amino acids that your body uses to synthesize proteins. These make this a perfect pre- or post-workout shake, because the protein and amino acids help your body rebuild the muscle that you broke down during your workout. And the flax seed oil is a good fat. In addition, I use half a box of frozen spinach and a cup of frozen fruit – my favorite, and the one in the picture, is the mixed berry mix from Target. It has blackberries, blueberries, raspberries, and strawberries and makes a really nice color. They also have a mix of strawberries, pineapple, and mango that tastes really good but looks like dirt 🙂

Ingredients in Blender


1/2 package frozen chopped spinach
1 cup of frozen mixed berries without added sugar
1 Scoop Vanilla Protein Powder *
1 tsp Glutamine Powder
1 tsp BCAA Powder
1 tbsp liquid L-Carnitine
1/2 tbsp Flax Seed Oil (liquid)
1 cup crushed ice
A little bit of water to help it blend

* I can’t tolerate sugar replacements so I use the regular kind, but only about 2/3 of a scoop. You can use the low-sugar or carb-control kinds if you want.

  1. Hi Susan, curious what is the benefit of L-Carnitine in a smoothie ? I don’t use much for supplements in smoothie (usually just superfood powders like Maca/Cacao/Flaxseed) but I always wondered how truly effective all these supplement are and if they really get absorbed in the body.
