Why is titanium dioxide used in supplements?

What other purposes would Titanium dioxide serve in a supplement other than colour enhancement/ whitener?

I believe that it can also serve as an anti-caking additive, similar to the use of SiO2. TiO2 is a fine white powder that is primarily used as a white pigment and/or visual enhancement additive. No idea if it is actually specifically used for anything other than pigmentation as a food additive, but I'd guess that it could have the additional benefit of reducing caking.
