Still many experts say the body of research does not support the current health concerns being expressed about titanium dioxide.

Overall, the Food Directorate's comprehensive review of the available science of TiO₂ as a food additive showed:

Ultimately, it comes down to whether you want to take the risk of having Titanium Dioxide in your blood stream?

We have long been passionate about avoiding exposure to Titanium Dioxide & are proud that our products offer a safe alternative to Women everywhere. We strongly urge you to ditch your toxic, unsafe makeup & find a safer alternative.

For a review published in 2023 in the journal Environmental Pollution, researchers examined E171 as a possible factor promoting obesity-related metabolic disorders. Because gut microbiota play an important role in immune function maintenance and development, and because titanium dioxide as a food additive has been shown to alter gut microbiota, researchers wanted to review “the dysregulations along the gut microbiota-immune system axis after oral TiO2 exposure compared to those reported in obese or diabetic patients, and to highlight potential mechanisms by which foodborne TiO2 nanoparticles may increase the susceptibility to develop obesity-related metabolic disorders.” The study authors discovered recurrent changes in the gut microbiota composition when exposed to titanium dioxide nanoparticles, with an imbalance of intestinal symbiotic microbiota. These changes and imbalances were also reported and played a role in the development of obesity, the authors wrote. This highlights “foodborne TiO2 nanoparticles as an endocrine disruptor-like chemical promoting obesity-related disorders,” the authors concluded.
