Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Silicic acid, a bioavailable form of silicon, is used in some supplements to support nail health. Scientific interest in silicon stems from its role in the synthesis and stabilization of connective tissue, including collagen, which is important for skin, hair, and nails. Several small clinical studies and reviews have explored the impact of silicon supplementation on nail strength and growth. A notable study published in "Archives of Dermatological Research" (2007) by Barel et al. found that supplementation with orthosilicic acid resulted in improved nail and hair quality in women with brittle nails and hair. Silicon is thought to enhance the structure and integrity of keratin, the primary protein in nails, potentially reducing brittleness and promoting growth.

However, while there is plausible biological rationale and some positive clinical findings, the overall quantity and quality of evidence remain moderate. Larger, well-controlled studies are lacking, and most research focuses on orthosilicic acid rather than other forms of silicic acid. Nevertheless, the available evidence does scientifically support the use of this ingredient for nail health, though the effect size may be modest and individual results can vary. Thus, silicic acid’s role in supporting the nails is backed by preliminary scientific evidence, reflected in a moderate evidence rating.
