Good Probiotic available in Canada

Hey folk,
Unless things have changed, I remember that it's very important for Lyme sufferer doing ABX to be on a good probiotic.
I also heard that it need to be in very potent in Acidophilus (10 billion or +)

I used to be able to get VSL#3 here in Canada, but it's no longer available.
What good probiotic do you use?

Hi Girlie, thanks for the answer.
How many HMF Forte do you take each day?

And could you give me another option you take?
I used to take Pure Encapsulation 50B but it was crazy expensive!
