Pour the almond milk into a high-speed blender.

Add the protein powder, chia seeds, flaxseed, and cinnamon.

Add the frozen blueberries, frozen banana, spinach, and ice cubes.

Blend on high speed for about 60 seconds until smooth and creamy.

Adjust consistency by adding a splash of almond milk if needed.

Let the smoothie rest for 3 to 5 minutes to allow the chia seeds to thicken the mixture slightly.

Pour into a serving glass and enjoy immediately.

For a thicker smoothie, add ¼ frozen avocado or extra frozen blueberries.

For a meal replacement version, add 2 tablespoons oats and 1 tablespoon almond butter.

For a lower-carb version, replace the banana with frozen zucchini.

For a dairy-free option, use plant-based protein powder.
