Glucon D is no doubt the best energy drink in India. Energy drink is not very expensive it comes in 3 flavours that is orange Yaman and original flavour.
This is very cheap but very effective methods for athletes to get energized within 20 seconds this product comes in the form of powder you can directly mix it with water and this dissolves very easily and forms a solution which can be fed directly.
I strongly recommend this energy ring to each and everyone in my family in to the athletes as well as this is the best one can get at this price range of 20 rupees for the packet and also having an additional offer of 30% discount on the MRP also uploading some pictures hope it helps.
