Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Zinc yeast is a form of supplemental zinc that is bound to yeast, often Saccharomyces cerevisiae, to enhance bioavailability. The use of zinc to support nail health is primarily based on scientific evidence regarding the essential role of zinc in cellular growth and repair, including the tissues that make up the nails. Zinc deficiency is well-documented to cause changes in the appearance and integrity of nails, such as white spots, brittleness, and delayed nail growth. These symptoms are reversible with zinc supplementation in cases of deficiency (source). However, while zinc is necessary for overall nail health, there is limited direct evidence that taking zinc yeast or other zinc supplements improves nail strength or growth in individuals who are not deficient in zinc. Most research focuses on correcting deficiency rather than enhancing nail quality in the general population. Some small studies and clinical observations suggest a potential benefit, but large, high-quality trials are lacking. Zinc yeast is often used in supplements due to its improved absorption compared to inorganic forms of zinc, but the benefit is related to its zinc content rather than a unique effect of the yeast complex itself. In summary, scientific evidence supports the use of zinc (including zinc yeast) for preventing or treating nail problems related to deficiency, but routine supplementation for additional nail support in healthy individuals is not definitively established.
