Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name FUCOSTEROL.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Fucosterol

Fucosterol is a 3beta-sterol consisting of stigmastan-3beta-ol with double bonds at positions 5 and 24(28). It has a role as an antioxidant, a metabolite and a hepatoprotective agent. It is a 3beta-hydroxy-Delta(5)-steroid, a C29-steroid, a member of phytosterols and a 3beta-sterol. It derives from a hydride of a stigmastane. — ChEBI
