The recipe to prepare this Immune Boosting Sunshine Smoothie is super easy. All you need is a good blender like this one. I prefer using fresh fruits and vegetables always. Add oranges, mango, pineapple, carrots and turmeric powder in the blender. Blend to make a thick juice. You can add ice cubes or water as well if you want. Now, I don't like to sieve the juice but if you wish to then you can sieve it and then consume it. These fruits are rich in Vitamin C which is essential for boosting your immune system and fighting off colds and infections.
