Last time I took a supplement with either of these in them, I broke out in a rash and my lips swelled up. Unfortunately, I don't want to experience that again! Silicon dioxide is used in making silicon chips, cement, and pesticides. I can't remember what the titanium dioxide is used for but I don't want to experience any more adverse reactions. Why would Doterra take something so good and pure and put these two things in it that are so bad?
Rob Young responded:
A very small amount of silicon dioxide, also called silica (the most common element on earth), and titanium dioxide (also a common earth mineral) are used as lubricating agents so material will flow into the two-piece gelatin capsules. They are extremely safe are would used throughout the food industry, as well as other industries. (Water is also used to make silicon chips, cement, and pesticides.) If you eat a carrot from your garden you will likely get a good dose of silica, a primary component of dirt. Some people even supplement with silica for stronger hair and nails. It is highly probable that something else in the supplement caused this person's rash and lip swelling. Silicon dioxide and titanium dioxide are found in many, many consumer goods. It is used in thousands of supplement products as a flow agent for filling capsules. Attributing an adverse reaction to these inert fillers is without scientific basis. We will be happy to refund your customers money for her purchase of the product if she still has concern.

The Silicon and Titanium Dioxides are used in the making of the gel caps holding our VM formula. Silicon dioxide is also used in our CRS gel caps. These ingredients are listed on the "other ingredient" section. These minerals are used in very small amounts. I have heard Rob Young estimate no more than 10mg of silicon and less than that of the titanum.
To give you an understanding... (One) 1oz is equal to about 28,000 (twenty eight thousand) Mg or 1oz = 28,349.50mg... the capsules contain no more than 10mg of each.
At least one of these minerals are used in approximately 75% of all capsules and tablets in the pharmaceutical industry.
They are both approved for human consumption by the FDA. (like I trust them)
Our Silicon dioxide is natural occurring form of the mineral silica source we use comes from horsetail extract. Silicon (Si) is present in more than one fourth of the earth's crust and is widely distributed in the soil, plants and water. In the body, silicon is found in highest concentrations in connective tissues such as collagen, tendons, cartilage, the trachea, blood vessels (particularly the aorta), eyes, dental enamel, bone, hair, and skin, specifically the epidermis. Silicon-deficient diets resulted in retarded growth, poor bone development, and more atherosclerotic arterial plaques in animal studies. Silicon has a similar healing potential on cartilage and joint degeneration as sulfur, so both can be helpful for various types of arthritis.
Next to bioflavonoids, silicon (or silica) are helpful in keeping blood vessel walls healthy, and it has been found that silicon concentrations of the thymus, skin, aorta and other arterial vessels decrease with increasing age and with the onset of atherosclerosis, which is reversible to some extent with oral or intravenous doses of silicon. Silica promotes the union of bone after a fracture, in contrast to calcium, which can actually slow the healing process or interfere with it altogether, especially when calcium levels are on the high side.
There is actually has a RDA/DRI (recommended daily allowance/daily recommended intake) of up to 500mg and it is estimated that the average adult comsumes between 20-50mg through mostly whole grains (oats and barley), sugar beets, sugar cane, soybeans, turnips, green beans and other vegetables.
The silica, is added during the manufacturing of capsules and tablets formulations to reduce clumping.
The Mineral Titanium dioxide is an opaque material that protects light-sensitive actives from photodegradation. It is regarded as an inert, non-toxic substance by the MSDS (Material Safety Data Sheets), USFDA and others charged with the responsibility of safeguarding the health of occupational workers and public health.
The U.S. Food & Drug Administration (2002) allows for its ingestion, external application including the eye area, and considers it a safe substance for public health. Other epidemiological studies showed that workers exposed to titanium dioxide exhibited no statistically significant relationship between such exposure any known disease.
The bottom line is that Titanium dioxide is listed as a safe pigment, with no known adverse effects. It is not listed as a carcinogen, mutagen, teratogen, comedogen, toxin or as a trigger for contact dermatitis in any other safety regulatory publications and the conclusion is by all health and regulatory organizations is that titanium dioxide is not a disease causing substance and is generally safe for use in foods, drugs, paints and cosmetics.
Despite these findings and conclusions, I would assume there will always be controversy. The mere fact that these minerals are "dioxides" will always raise an eyebrow. People will have to come to there own conclusion on the minerals.
BTW, I have never heard nor seen indications that Silicon Dioxide can be an allergenic, however I have heard of rare cases where Titanium Dioxide has caused allergic reactions.
These are both generally accepted as inert minerals.
