What You Need
All ingredients are widely available and easy to work with. Here’s a quick breakdown of what each ingredient contributes and why it works well in this recipe:
- Blueberries — Use frozen blueberries for a chilled smoothie and concentrated flavor. Blueberries add natural sweetness and provide vitamin C and beneficial plant compounds.
- Ground flaxseed — A convenient way to add fiber and plant-based omega-3s (ALA). Ground flax blends evenly and helps thicken the smoothie slightly.
- Spinach — A mild-tasting green that blends seamlessly into fruit smoothies. It adds vitamins, minerals, and a serving of leafy greens without dominating the flavor.
- Greek yogurt — The secret to a creamy texture and added protein. Choose full-fat, low-fat, or dairy-free yogurt depending on your preference.
- Milk or milk alternative — Use almond, coconut, oat, or cow’s milk to reach your desired consistency. Thicker milks create a richer smoothie; lighter milks make it more drinkable.

Our Favorite
Blender
A high-speed blender will make this smoothie very smooth, especially when using frozen fruit and ground flaxseed. If you only have a standard blender, pulse until ingredients are evenly combined and let frozen fruit warm slightly if needed.

Flaxseed Smoothie 101
Are flaxseed smoothies healthy?
Yes — when balanced and made with wholesome ingredients, flaxseed smoothies can be a nutritious choice. Flaxseed contributes fiber and plant-based omega-3 fatty acids, while fruit and yogurt supply vitamins, minerals, and protein. Pay attention to portion sizes and overall daily caloric intake, and use smoothies as part of a varied diet rather than as the sole daily meal.
What are the best smoothie toppings?
Toppings add texture and visual appeal. Try a sprinkle of extra ground flaxseed, a few fresh or frozen blueberries, a spoonful of granola, chopped nuts, chia seeds, or a drizzle of nut butter. These toppings increase satiety and make your smoothie bowl-style serving more interesting.
How much flaxseed should you use?
For one serving, 1/2 to 1 tablespoon of ground flaxseed is a sensible amount. This provides fiber and healthy fats without overwhelming the flavor. Start with 1 tablespoon and adjust to preference.
Protein and Add-ins
If you want to boost protein further, consider adding a scoop of protein powder (plant or whey), a spoonful of nut butter, or extra Greek yogurt. Adjust the milk quantity to reach your preferred thickness.
