Introduction	Silicon ranks as the second most prevalent element on Earth and the third most abundant trace element in the human body. Found in water, plants, and animals, silicon is believed to be crucial for collagen synthesis and the activation of hydroxylating enzymes, enhancing skin strength and elasticity. In terms of hair benefits, increased silicon content is associated with reduced hair loss and enhanced shine. The rising interest in scientific studies on silicon dietary supplements is driven by their potential to elevate blood silicon levels, thereby improving skin and hair appearance. Various forms of silicon supplements are available, with bioavailability as a key selection criterion. Silicon supplements exhibit a wide range of bioavailability, from less than 1% to roughly 50%, based on the chemical form. The study aims to assess scientific literature on the chemical forms of silicon supplements, their limitations, and recent advancements. Among these forms, orthosilicic acid (OSA) offers the highest bioavailability, while others show absorption inversely related to polymerisation levels. However, clinical studies on safety and efficacy remain scarce.
