Frequently Asked Clinical Questions

Q: How do I check if my daily vitamins contain Titanium Dioxide?

Look at the 'Other Ingredients' section below the Supplement Facts box. If the capsule is bright opaque white, check for 'Titanium Dioxide' and switch to transparent capsules.

Q: Why was Titanium Dioxide banned in Europe but not the FDA?

The EFSA applies a precautionary genotoxicity threshold for nanoparticles (<100nm), whereas the FDA still relies on a 1966 bulk-pigment petition.
