in Pattaya?

I think not.

The very large drug store on Pattaya Nua called Fascino (coming from Sukhumvit, on the left past the first set of traffic lights - has its own parking area)which has an extensive range of health food supplements, vitamins, etc. It's the best I've seen in Thailand - but maybe not what you're looking for. I get my cod liver oil and Omega 3 tablets there, but I can't find glucose tablets anywhere.
