Here in Germany, Vitamin C is available as effervescent tablets and as capsules in 1 000mg sizes. The problem, though, is not necessarily Vitamin C as such, but the combination of ingredients in a given formula. It is fairly regular to see a formula classified as a drug due to the specific concentrations of the used ingredients, even if the separate ingredients are classified as food supplements. It would, for instance be next to impossible to convince the German Customs that Green Tea Extract (standardized for 98% Polyphenols, 60% Epigallocathechingallate (EGCG)) 500mg is a food supplement. For them, and for the health authorities, it is a drug, even though Green Tea leaves are food supplements, regardless of quantity! Tongkat Ali in capsule form would not be allowed into Germany. Yet, importation in powdered form is not restricted. In this form, it is referred to as a forest product. The list can be continued. Weird, right? The life of an athlete is fairly complex here, guys!
