I have just received a pack of 30 sachets which I ordered via Amazon and the sachets are just plain white with the batch number and expiry date printed on them. This struck me as a bit odd as although I have never used this particular product before any other sachet medication I have used has always had the ingredients and instructions on how to take the product printed on each individual sachet. Does anyone use this product and if so is it normal for it to come as I described above? Thanks
