In Australia we have Sustagen. They also make a medically approved "Sustagen Hospital Formula" which is used by hospitals as a full meal replacement for extended periods (I've lived of it for multiple multi-month periods due to health issues). It is available in all supermarkets, and most corner stores and convenience stores. As someone with serious medical issues who depends on meal replacements regularly, and through that experience has learned how important the right mixes are, I wouldn't touch Soylent with a ten foot pole. I'm really really worried (and convinced) people are going to end up with pretty serious health issues from Soylent but the fanboyistic reception it gets saps my energy to bother arguing with people about it.
