Silicon
Synopsis of silicon
Silicon is a trace mineral essential to human health, primarily known for its role in supporting connective tissue strength, bone formation, and skin integrity. Though not classified as an essential nutrient in the traditional sense, growing evidence suggests that silicon contributes significantly to the structural integrity of collagen, elastin, and glycosaminoglycans—all key components of skin, cartilage, tendons, and bones.
Silicon in the body is most bioavailable in the form of orthosilicic acid (OSA), which is found in small amounts in drinking water, fruits, vegetables, whole grains, and certain herbs like horsetail (Equisetum arvense). It contributes to collagen synthesis and is believed to help improve bone density, enhance hair and nail strength, and promote skin elasticity. In supplement form, silicon is often included in beauty, joint, or bone support formulas and is commonly sourced from stabilized orthosilicic acid or bamboo extract.
Beyond its structural benefits, silicon may have a role in cardiovascular health by supporting arterial wall elasticity and may help chelate aluminum from the body, reducing its neurotoxic potential. However, more research is needed to define its broader physiological roles and establish standardized dietary requirements.
Historical Use:
While silicon as a chemical element (Si) was first identified in 1824 by Swedish chemist Jöns Jacob Berzelius, the use of silicon-rich plants in traditional medicine predates its scientific discovery by centuries. The most well-known historical source is horsetail (Equisetum species), a plant exceptionally high in bioavailable silica (the compound form of silicon), used since ancient Roman and Greek times to strengthen bones, stop bleeding, and promote wound healing.
In Traditional Chinese Medicine and Ayurveda, silicon-rich herbs were used to tonify the kidneys, support the skeletal system, and rejuvenate the skin and hair. Horsetail, nettles, and bamboo were often consumed as teas or poultices to address weak nails, slow wound healing, or brittle bones—conditions now understood to be linked to connective tissue and mineral deficiencies.
In more modern herbal traditions, the role of silica (and by extension, silicon) became clearer as naturopaths and herbalists began to focus on tissue regeneration, arthritis, and anti-aging therapies. By the 20th century, colloidal silica and orthosilicic acid began appearing in health products marketed for bone health, joint flexibility, and youthful skin.
