Green Protein Smoothie Health Benefits
Promotes Feeling of Fullness
This green protein smoothie is high in fiber due to the banana and spinach.
Fiber increases satiety because it’s slowly digested by the body.
The protein in this smoothie also reduces feelings of hunger.

After physical activity, the muscles need protein to recover and get bigger.
That’s why it’s recommended to get a lot of protein within 1 hour of working out.
Thanks to this drink, you can make quick protein-rich snack to easily increase your protein intake.
Fights Oxidative Stress
Eating foods high in antioxidants is key for good health.
Antioxidants help reduce oxidative stress, which lowers the risk of disease.
Drinking this smoothie is a delicious way to get more antioxidants. The spinach, banana, and hemp seeds are all great sources.
Enhances Immune Function
Vitamin C is an essential nutrient for good immunity.
Spinach, which is used in this smoothie, is high in vitamin C.
The nutrient supports immune function by helping your cells fight bad germs.
Helps Digestive Health
The fiber in banana and spinach are needed for good digestion.
When you eat enough fiber, you’re more likely to have more regular bowel movements. This can reduce the risk of digestive issues.

Ingredient Notes

- Unsweetened almond milk
Since this recipe has date syrup for natural sweetness, it’s best to use unsweetened almond milk. If you want to increase the protein content of your smoothie, choose soy milk or dairy milk instead. - Date syrup
A natural sweetener that’s delicious in smoothies. - Hemp seeds
Hemp seeds add protein, along with anti-inflammatory fats and vitamins. - Vanilla protein powder
Both whey and vegan protein powders work well in this recipe. If you don’t like the flavor of vanilla, feel free to use unflavored protein powder. - Baby spinach
Baby spinach gives this smoothie its bright green color. It’s also a great source of antioxidants and vitamins. The flavor is less bitter than kale, so it works well with vanilla. - Frozen banana

Optional Add-Ins
Extracts
For a stronger vanilla flavor, add ½ teaspoon vanilla extract.
You can also use vanilla extract with unflavored protein powder for a similar flavor profile.
Leafy greens
If you want a stronger green smoothie taste, add another handful of baby spinach.
Another option is to add a handful of baby kale for an earthier taste.
Green powder
Add a scoop of green powder to increase the greens in this recipe.
Made of dried and crushed fruits and vegetables, green powders are very high in nutrients.
Depending on the brand, the green powder might add a slight fruity flavor to your drink.

Blender Tips
Cut fruits into pieces.
Protect the blades of your blender by chopping fruits before freezing them.
For this smoothie, you’ll need to freeze bananas. Be sure to slice them into coins first.
If you have a powerful blender, you can cut them into slightly bigger chunks.
Never put a whole frozen banana in your blender, which can damage the blades and container.
Add ingredients from lightest to heaviest.
To ensure the blades of your blender move efficiently, load the lightest ingredients first.
This includes your liquid base and liquid add-ins. Next, load other add-ins like powders, nut butters, and seeds.
Continue with leafy greens, fresh fruit, and frozen fruit and ice.
Rotate ingredients with a tamper.
An easy way to encourage a smooth blend is to use a tamper.
While the blades are moving, insert the tool through the lid. Move it in a circle, making sure to hit all 4 sides of the blender jar.
This will create a vortex and move ingredients toward the blades.
Scrape out leftover smoothie.
Instead of rinsing out leftover smoothie, remove it using a blade scraper.
It’s a tool designed to reach under blades and get out every last drop.
Expert Tips
- Choose bananas that have a yellow peel with brown spots. This means the bananas are ripe and ready to use.
- If you want to thin the smoothie, add a splash of milk and blend for another 10 seconds.
- For a thicker drink, add extra frozen banana or a few ice cubes.
- You can use a pitted and chopped Medjool date in place of date syrup.
- Regular spinach can be used instead of baby spinach. Be sure to slice away any hard stems.
- Keep leftover smoothie in an airtight jar in the refrigerator. Drink it within 1 or 2 days for the best flavor and texture.
Questions You May Have
Yes, as long as you’re eating a balanced diet and getting protein from other foods. Also, since protein powder is a supplement, be sure to check with your doctor before drinking protein smoothies every day.
The sweetness of the vanilla protein powder balances the earthiness of leafy greens. You can also use unflavored protein powder if that’s what you have.
If you’re not lactose-intolerant, you can use cow’s milk in this smoothie. It will increase the protein content of the drink.
