As it turns out, vitamins are mostly expensive in Thailand. So if you are a fan of vitamins, like I am, and you are travelling, make sure you bring your favourites from home.
I went to stock up on my Vitamin Cs and discovered they are 239THB (AUD$9.11) – which seems like a lot for a basic Vitamin C.
Also, the range in Thailand is VERY small, not like the rows and rows of vitamins you can find in Australia.
