Turn almost any bottle of vitamins over, read down past the actives, and there’s a fair chance you’ll spot titanium dioxide near the bottom. It isn’t doing anything for you — it’s there to make the tablet look bright, white and uniform. Here’s how to recognise it, and how to find supplements that leave it out.

Why it’s in supplements at all

Titanium dioxide is an appearance ingredient, not a functional one. It’s used as a coating on white tablets, sometimes in coloured capsule shells, and very commonly in gummies. Because it does nothing nutritionally, it sits in the “other ingredients” line rather than the actives — which is exactly why it’s so easy to scroll past.

Where to look on the label

Scan the “other ingredients” or excipients line, not the actives. It may be written as “titanium dioxide,” “colour,” or “CI 77891.” Plain capsules and powders are the quickest to check; coated tablets and gummies are where it most often turns up.

The format matters more than the brand

Here’s the part that catches people out: the same brand can use titanium dioxide in a coated tablet while leaving it out of its plain capsules. So a brand being “clean” in one product doesn’t guarantee it across the range. As a rough rule, capsules and powders are lower-risk; coated tablets and gummies are worth a closer read.

Finding ones without it

You don’t have to check every label from scratch. Our Supplements & Vitamins list in the Titanium Dioxide–Free Directory gathers products we’ve reviewed and found titanium dioxide–free at the time of checking, organised so you can skip the detective work. Formulations change, so treat it as a starting point and check the current label before you buy

Frequently Asked Questions

1. Why is titanium dioxide used in supplements?

It’s used for appearance only — to make tablets, capsule shells and gummies look bright, white and uniform. It has no nutritional function, which is why it sits in the "other ingredients" line rather than the actives.

2. Do all products from one brand contain titanium dioxide?

No. The same brand may use it in a coated tablet while leaving it out of its plain capsules, so the format matters as much as the brand. Plain capsules and powders are generally less likely to contain it than coated tablets and gummies.

3. How do I spot titanium dioxide on a supplement label?

It appears in the "other ingredients" or excipients line — sometimes written as "titanium dioxide," "colour," or "CI 77891" — and never in the active ingredients. Capsules and powders are the easiest to scan; coated tablets and gummies are where it most often appears.

4. Are gummy vitamins more likely to contain titanium dioxide?

Often, yes. Gummies and coated white tablets commonly use it for a bright, uniform look, while plain capsules and powders frequently leave it out. It’s still worth checking the specific product, as formulations vary.

5. How can I find supplements without titanium dioxide?

The MG Naturals Titanium Dioxide–Free Directory keeps a reviewed Supplements & Vitamins list of products found without titanium dioxide at the time of review. Formulations can change, so always check the current label before purchasing.
