I've been looking into getting some over here in the UK, largely to get my stepdad onto it because he has all manner of issues that I think Curcumin could help remediate.
The only problem is, none of the UK-based product is of the same quality as the Biotest stuff (with respect to added Piperine to aid bioavailability). In turn I'm not sure I can convince him to shell out for imported Biotest goodness on a regular basis, nor can I afford to provide it for him, or myself. Sad face.
So if anyone hears of a viable UK alternative to the Biotest magic, or a Biotest importer that isn't a bandit masquerading as an online retailer, then I'm all ears.
