My wife is on these supplements for low stomach acid, she has not joined me out here yet, but we were going to get them sent from the UK as we weren't sure if they are available here.
It might be worth trying the internet if you have a PO box that they can be sent to, when my wife ran out of them she found it helpful to eat an orange with a meal as this does increase the stomachs ability to break down the fats.
Don't use a lemon as these turn alkiline in the stomach and make the problem worse.
Good luck
