Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth’s most abundant materials: silicon (Si) and oxygen (O2).
Silicon dioxide is found naturally in water, plants, animals, and within the Earth. Silicon dioxide makes up more than 95 percent of known rocks on the planet. It’s even found naturally in the tissues of your body, and does not collect in the human body.
Why Is It in Food and Supplements? Along with being found pretty much everywhere on earth, silicon dioxide is found in foods and supplements. Why?
Although, it is not added into Promanatein, Silicon dioxide serves as an effective anti-caking agent for the industry. It is used to prevent clumping. In supplements, it’s used to prevent the various powdered ingredients from sticking together.
Numerous studies have found no health risks associated with this particular ingredient.
Silicon dioxide is found naturally in many plants. For example, leafy green vegetables, beets, bell peppers, brown rice and oats, and alfalfa. Therefore while it is in Promanatein, it is only there due to its natural occurrence in organic spinach and other natural ingredients.
