Synopsis

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

Vegetable juice has traditionally been used as a general health tonic, with some claims extending to support for nail health. The rationale is that vegetables contain a range of vitamins and minerals—such as vitamin C, vitamin A, biotin, and zinc—that are involved in the maintenance of healthy nails. However, while the general connection between adequate micronutrient intake and healthy nails is supported by science, there is limited direct evidence that vegetable juice, specifically, has a significant or unique effect on nail health beyond its role as a source of nutrients. Historical and traditional practices often promote vegetable juices for "beauty from within," but scientific studies directly linking vegetable juice consumption with improved nail strength or growth are lacking. Most of the support comes from the logic that deficiencies in certain nutrients (like biotin or zinc) can cause brittle or unhealthy nails, and vegetable juice may help correct such deficiencies if present. In summary, while there is a traditional basis for using vegetable juice to support nail health and a plausible nutritional rationale, strong scientific validation specific to this use is currently lacking.
