Add the chopped beetroot, frozen berries, and banana to a high-speed blender.
Pour in the almond milk and fresh lemon juice over the solid ingredients.
Add the grated ginger and chia seeds (if using) to the blender.
Blend on high speed for 60 to 90 seconds until completely smooth and creamy.
Taste and adjust sweetness with a little honey or maple syrup if desired.
Add ice cubes and blend again briefly if you prefer a chilled, thicker consistency.
Pour into a glass and consume immediately for the best flavor and nutrient retention.
