Silica is a chemical compound that has an unclear role in the body. There is no recommended daily amount of silica to consume.
Some studies suggest that silica plays a role in bone and connective tissue development and structure.

What is silica?
Silica is a chemical compound that can be ingested in the diet. However, the amount of silica that the body needs is unknown. As a result, it is not classified as an essential vitamin or mineral. Silica is found in one of its forms, orthosilicic acid, in numerous tissues in the body including the bones, tendons, aorta, liver, and kidneys (3). However, at the present time, information about silica in the body is very limited.
Where does silica come from?
Silica can be found in sand or in the soil. It is commonly used as an additive in foods, where it serves purposes like functioning as an anti-caking or anti-foaming agent. It is commonly thought that silica is only ingested by drinking water or beer but silica is also present in grains, breads, and certain fruits and vegetables (2).
What are the bone health benefits of silica?
Studies show that silica may be beneficial for bone and connective tissue development. One possible reason why is that silica may be involved in the synthesis and stabilization of collagen (1). Studies in animals have shown that when silica is restricted, growth is reduced and bone defects occur. Studies also show that silicon supplementation in postmenopausal women with osteoporosis can increase bone mineral density (2). Supplementation has also been seen to improve bone quality, bone strength, and bone mineralization (4). However, information about all of these effects is very limited.
How much silica is recommended?
There is no recommended amount of silica that should be consumed each day.
How does Roman offer silica?
Roman obtains silica from non-GMO sources in China and the USA. It is available synthetically as silicon dioxide.
Roman offers silica in the following supplements:
Silica is one of ten main ingredients in Roman’s Bone Health supplement. The supplement consists of three tablets that should be taken with water. Each individual tablet contains 8.33 mg of silica, for a total daily dose of 25 mg.
Other ingredients in the tablets include ascorbic acid, calcium citrate, D-alpha tocopheryl succinate, magnesium citrate, boron citrate, menaquinone-4, menaquinone-7, phytonadione, cholecalciferol, microcrystalline cellulose, stearic acid, dicalcium phosphate, croscarmellose sodium, magnesium stearate, and pharmaceutical glaze (shellac, povidone).
Does silica interact with any other drugs or medical conditions?
Currently, there are no well-documented instances of silica adversely interacting with other drugs or medical conditions. Breathing in dust that contains silica may cause the lung disease silicosis. However, silicosis is not related to taking silica supplements.
