Being natural means you are taking everything organic, there is no artificial ingredient not unless your thinking of mixing up the two. You cannot say you want an energy drink that has no caffein, even if you went all over searching, so long as they are found on the shelves in the supermarket, you can be rest assured it is not 100% natural or free from caffein. Some of tbis products have writings on them that will only please the buyer, but in actual sense, tbey have hidden additives it's just that we don't get to see them because they are not listed in the ingredients on the packets. If you are planning to go natural, make your own drinks at home, that way you will never go wrong. Buy the fruits and vegetables you need that are rich in vitamins and other minerals, then blend them together and drink. All the nutrients there will give you the most needed energy. Don't count on drinks on the shelf, those are full of chemicals.
