Having considered the cost of energy drinks, I have been wondering about making up the equivalent type of drink without the inherent cost.
Would anyone care to comment on the following recipe:

4 tbs glucose powder (available at any high street pharmacist
1 tps salt
Any additive free diluteable juice for flavour
1 Litre of water

As far as i can tell most of the needed nutrients are included, but i'm sure wiser people than me to help to clarify.
