The trace elements selenium and zinc are frequently mentioned in nutritional science in connection with hair and nails, yet they are rarely placed in a clear context. Which statements are actually authorised? Which ones rest on reviewed data, and which are marketing?
This guide focuses exclusively on claims authorised under EU Regulation No. 432/2012. No interpretation of our own, no inflated promises — only what the evidence supports.
Each of these statements has been assessed and approved by the European Food Safety Authority.
„Selenium contributes to the maintenance of normal hair.“Under Regulation (EU) No 432/2012
The guide explains what this authorised claim means in practice, how it was scientifically assessed, and in which context it holds.
„Selenium contributes to the maintenance of normal nails.“Under Regulation (EU) No 432/2012
Alongside the contribution to normal hair, EFSA also documents selenium's contribution to the maintenance of normal nails. The guide places both statements in context.
„Zinc contributes to the maintenance of normal hair.“Under Regulation (EU) No 432/2012
Zinc, too, has an EFSA-documented contribution to the maintenance of normal hair. The guide sets out how the claims for selenium and zinc relate to one another.
A clear progression — from the fundamentals through to practical context.
