There is lack of information about the material always. https://www.healthline.com/health/food-nutrition/is-silicon-dioxide-in-supplements-safe What does the research say? The fact that silicon dioxide is found in plants and drinking water suggests it’s safe. Research has shown that the silica we consume through our diets doesn’t accumulate in our bodies. Instead, it’s flushed out by our kidneys. However, the progressive, often fatal lung disease silicosis can occur from chronic inhalation of silica dust. This exposure and disease primarily occurs among people who work in: mining construction quarrying the steel industry sandblasting While many of the studiesTrusted Source on silica have been done on animals, researchers have found no link between the food additive silicon dioxide and increased risk of cancer, organ damage, or death. In addition, studiesTrusted Source have found no evidence that silicon dioxide as an additive in food can affect reproductive health, birth weight, or bodyweight. The U.S. Food and Drug Administration (FDA) has also recognized silicon dioxide as a safe food additive. In 2018, the European Food Safety Authority urged the European Union to impose stricter guidelines on silicon dioxide until further research could be done. Their concerns focused on the nano-sized particles (some of which were smaller than 100 nm). Previously guidelines followed a 1974 paper prepared in association with the World Health Organization. This paper found the only negative health effects related to silicon dioxide have been caused by silicon deficiency. More current research may be changing the guidelines and recommendations. Have safe limits been set? Though the research so far suggests there aren’t many risks associated with silicon dioxide ingestion, the FDA has set upper limits on its consumption: Silicon dioxide shouldn’t exceed 2 percent of a food’s total weight. This is mainly because amounts higher than these set limits haven’t been sufficiently studied.
