What is Silica?
Silica, or silicon dioxide, is a naturally occurring mineral that is found in various forms, such as quartz or sand. It is manufactured for food and supplement products by processing high-purity quartz to create a fine, food-grade powder.
In the food industry, silica is primarily used as an anti-caking agent to prevent clumping, ensuring smooth texture and easy flow of products like dry powders. Health-wise, silica is generally recognized as safe (GRAS) by the FDA, with most research indicating it poses no risks at typical consumption levels. However, very high doses could cause issues, although such amounts are not common in food products.
When seeing silica on a label, it's mostly present in small amounts. It's important to consider its role in maintaining the quality and consistency of the product rather than as a major dietary source.
Commonly found in: Supplements, Powdered Spices, Baking Mixes, Cosmetics, Pharmaceuticals
