Supplements & Vitamins

A note on this category

Titanium dioxide appears in supplements and vitamins as a whitener and opacifier — most often in the coating on white tablets, sometimes in coloured capsule shells, and frequently in gummies. It's rarely the first thing you notice, because it sits in the “other ingredients” line rather than in the actives. And to make it more confusing, the same brand can use it in a coated tablet while leaving it out of its plain capsules. Because ingredient lists can vary between countries and even between batches, this is a category where checking the current label genuinely matters.

This page lists products reviewed and found to be titanium dioxide–free at the time of inclusion, based on publicly available ingredient information.

As a general pattern, plain capsules and powders are less likely to contain titanium dioxide than coated tablets and gummies — but that's a starting point, not a rule. Because it's used for appearance rather than function, it shows up most where a product needs to look bright, white, or uniform.

If a brand makes both capsules and tablets, the format matters as much as the name on the bottle — so it's worth checking the specific product, not just the brand.
