Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Soybean is primarily justified for supporting the nails body system through scientific evidence, although the strength of the evidence is modest. Soybeans are a rich source of protein, biotin, and minerals such as zinc and iron, all of which are important for healthy nail growth and structure. Several studies have indicated that adequate protein intake is necessary for the production of keratin, the main structural component of nails, and soybeans provide a complete plant-based protein source. Additionally, deficiencies in biotin and certain minerals can lead to brittle or weak nails, and soybean products contribute to meeting daily requirements for these nutrients.

However, it is important to note that there is limited direct research specifically investigating the effect of soybean consumption on nail health in humans. Most evidence is extrapolated from general nutrition studies showing the importance of protein and micronutrients for nail integrity, rather than from studies on soybeans specifically. Therefore, while scientific rationale exists and soybeans can play a role as part of an overall nutrient-rich diet supporting nail health, strong clinical evidence directly linking soybean intake to improved nail health is lacking. For this reason, the evidence rating is moderate.
