I have been using Glucon D from my childhood.It’s a powder which is generally used after physical exercise or work.It helps to increase the glucose level instantly which is lost during strenuous labor.Increase in glucose level provides instant energy to the body.It is mostly used by sportsman.
I basically preferred this brand over others as its consistently maintaining the quality and it is often suggested by the physicians though.It is the most trusted and effective product as compared to other.
