I would think Linda's approach of having a glucose tablet in your purse would be an idea. The other thought I had was to get an empty medicine bottle (type pharmacists dispense liquid anti-biotics in) and fill it with orange juice, if you have a friendly pharmacist they might be willing to print a label with your name and something like "Ascoribic acid solution, use as required" for the bottle.
However, I think it would be appropriate for you to speak either with the supervisor's manager or the human resources manager, your requests are not unreasonable, especially if you say that you want to have glucose tablets (use the word tablet) on hand and not necessarily candy.
Just my rambling thoughts,
