If your blender is not quite powerful, grate the ginger and blender carrots alone first with a cup of water before adding the rest of the ingredients.
You can ground a batch of flax seeds and store them in your fridge for about a week.
I use plant-based yogurt, but use any of your choices as long as it's not sugared!
I use freshly harvested carrots, so no need of peeling them. If you buy carrots with dirt, make sure to clean them well.
I use boiled sweet potatoes when making smoothies as they have water content compared to baked/roasted ones that are rather dry and may require extra water to make the smoothie!
