I'd love to get someone's perspective that actually lives over there, but, according to this article, the EU is being very strict with supplement manufacturers claim:
"The NHCR has banned 100s of claims on products that consumes across Europe have been familiar and comfortable with for years. Claims such 'dietary fibre helps maintain a healthy digestive system' and 'glucosamine helps maintain joints' are both well understood. To ban these, and claims like them, not only prevents our industry from developing products based on well-dcomented science, but also causes confusion in the minds of our consumers.""
