Synopsis

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

Sulphur is an essential mineral involved in the synthesis of keratin, a key structural protein found in nails, hair, and skin. Scientific literature supports the role of sulphur, particularly in the form of amino acids such as cysteine and methionine, in maintaining the structural integrity and growth of nails. These sulphur-containing amino acids are critical for forming the disulfide bonds that give keratin its strength and resilience. Deficiency in sulphur amino acids can lead to weakened or brittle nails. While most people obtain sufficient sulphur through dietary protein, certain supplements containing sulphur compounds (e.g., methylsulfonylmethane, MSM) are marketed for nail health. Some small-scale studies and anecdotal evidence suggest that MSM supplementation may improve nail strength and appearance, though large-scale, robust clinical trials are limited. Therefore, while the biological basis for sulphur’s importance in nail health is clear, high-level clinical evidence for supplementation specifically to improve nail condition is moderate. In summary, sulphur’s role in supporting nail health is scientifically grounded, but the extent of benefit from additional supplementation beyond a normal diet remains an area for further research.
