Place the ingredients into blender. Frozen berries and ice cubes can be added to a smoothie to make it cold. Any type of berry can be used; most are very nutritious and full of antioxidants and phytonutrients. Banana is rich in potassium and lends a creamy consistency to the drink. Adding water, juice or milk helps blend everything together and alter the consistency. As both juice and milk have calories, purified water is ideal.
Place the lid securely on the blender and blend the contents. You may need to blend the mixture a little longer if large, hard or frozen ingredients are included. Generally, a smooth consistency starts to take shape after thirty seconds or 1 min. If there are still chunks in the blender, let it run a little bit longer.
Stop the blender add one scoop of wheatgrass powder to the contents. If the smoothie appears very thick, as if it would be hard to drink, add a little more water, juice or milk or yoghurt, up to 1/4 cup, to thin it.
Blend the contents again for about 30 seconds or until the smoothie has reached the desired consistency.
It is now ready to drink. Do not be alarmed by the color of your smoothie; depending on the fruits and juice you added and the color of wheatgrass powder, the final result may look a little green or brown, this is OK. Some settling will occur if you leave it which may look unappetising but tastes fine.
