There are at least half a dozen different brands available in Australia. They are all imported from Europe. For example, the one I am eating at the moment is calle Krautboy by a company called Kramers. They either come in a can or a jar, but I prefer the jar. In the US you can but it from Wholefoods and the brand is called Rejuvenative Foods. They have a website - WWW.REJUVENATIVE.COM
They are based in Santa Cruz in California. I know this because I work for an airline and travel a few times a year to LAX and when I am there I but the stuff from Wholefoods at Redondo Beach.
I stayed on Threelac with the Oxygen Elements for about 6 months. I felt well about 1 week in for a period of about 2 weeks. After that there was no improvement.
