Is Titanium Dioxide Safe During Pregnancy?
The facts: Titanium Dioxide is banned in 2 countries/regions (including European Union (banned as food additive E171 since August 2022), France (banned nationally in 2020, first EU country to do so)), though the FDA still allows it in the US. We can't tell you whether it's safe for your pregnancy — that's a conversation for your OB-GYN or midwife. What we can do is show you the regulatory facts and flag Titanium Dioxide on any product's label so you can decide with your provider. Commonly found in: Skittles (US formulation), Starburst shells, M&Ms (white coating).
TL;DR: Titanium Dioxide is banned in the EU and allowed in the US. Here's what to know if you're pregnant.

What is Titanium Dioxide?
Titanium dioxide (TiO2) is a naturally occurring white mineral used as a food colorant, whitening agent, and opacity enhancer. In food applications, it exists as nano-sized and micro-sized particles. It is one of the most widely produced industrial minerals globally, used in paints, plastics, sunscreens, and food products.
Why is Titanium Dioxide used in food?
In food, titanium dioxide provides intense white color and opacity to candies, chewing gum, salad dressings, coffee creamers, and cake frostings. It gives products a bright, appealing white appearance. In sunscreens and cosmetics, it serves as a UV filter. Its historically perceived inertness made it considered safe for decades.
What regulators have flagged about Titanium Dioxide
The EU banned titanium dioxide as a food additive in 2022 following EFSA's landmark 2021 safety assessment (EFSA Journal 2021;19(5):6585), which concluded that titanium dioxide 'can no longer be considered safe as a food additive.' The primary concern is genotoxicity from nanoparticles: EFSA determined it was impossible to rule out the risk of DNA damage (genotoxicity) from TiO2 nanoparticles at typical food use exposure levels. In vitro studies have demonstrated that TiO2 nanoparticles cause DNA strand breaks in intestinal epithelial cells and induce oxidative stress. A 2019 study in Nature Communications found TiO2 nanoparticles could disrupt gut microbiome balance and intestinal barrier function in mice models. Multiple studies have suggested effects on gut permeability and immune function. IARC classifies titanium dioxide as Group 2B (possible human carcinogen) for inhalation exposure in occupational settings — primarily relevant to workers handling TiO2 dust, based on rat lung cancer studies. While inhalation and oral exposure are different routes, EFSA determined that the genotoxicity concerns from nanoparticles applied to oral food use as well. Following the EU ban, California attempted to pass legislation banning TiO2 in candy (along with other additives) in 2022. The bill was signed in modified form. Mars reformulated EU Skittles to remove TiO2. The US FDA has not announced specific action on food-grade TiO2 as of 2025, though USRTK and other organizations are calling for a US ban.

Titanium Dioxide and pregnancy: common questions
Is Titanium Dioxide banned anywhere?
Yes. Titanium Dioxide is banned in European Union (banned as food additive E171 since August 2022), France (banned nationally in 2020, first EU country to do so); restricted in United Kingdom (post-Brexit review underway; FSA monitoring EFSA evidence). The FDA still allows it in the US.
Should I avoid Titanium Dioxide during pregnancy?
That's a decision for you and your OB-GYN or midwife — we don't give medical advice. What we can tell you is the regulatory status above. Many people choose to limit additives during pregnancy out of caution; bring this page and its sources to your next appointment.
What foods contain Titanium Dioxide?
Commonly found in Skittles (US formulation), Starburst shells, M&Ms (white coating), Many chewing gum brands, Salad dressings, Non-dairy coffee creamers. Scan any product's barcode to check its label for Titanium Dioxide.
What can I use instead of Titanium Dioxide?
Calcium carbonate provides whiteness and opacity in confections as a TiO2 alternative. Calcium sulfate, starch-based whiteners, and reformulated coatings without white pigment are other options. European manufacturers successfully reformula See the pregnancy-conscious swaps below.
