Do the Dr Reddy's sachets contain 75g of anhydrous glucose or the monohydrate?

Subject: Re: OGTTs and Lucozade

Dear Fiona,
There are one or two problems with Lucozade. The larger volume needed (411 mL) is probably not going to matter, given that patients can drink water before the OGTT. More importantly, however, is the question of whether the presence of sodium in the liquid can somehow influence the rate of uptake of glucose by Na+/glucose co-transporters. There is some indirect evidence to suggest that sodium (and aldosterone) can or may. Add to this the uncertainties or the mistakes made in buying the formulations that contain fructose and caffeine.
You can use either Polycal or Maxijul (both come in powder as well as flavoured liquid), but the easiest is to use Dr. Reddy's lemon-flavoured glucose that comes specifically in 75-gram sashets for this purpose at someting like 80p each (cheaper than Lucozade as well!).
Bets wishes,
Reza
