Synopsis

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

Brewer's yeast has a long history of use as a nutritional supplement, and its use to support or treat "nervousness" is primarily based on traditional practices rather than robust scientific validation. Historically, brewer's yeast has been valued as a rich source of B-vitamins, particularly thiamine (B1), riboflavin (B2), niacin (B3), and folic acid, which are essential for normal nervous system function. Folk medicine and early nutritionists often recommended brewer's yeast as a "nerve tonic" or remedy for nervousness, anxiety, and mild mood disturbances, believing that B-vitamin deficiencies could contribute to such symptoms. However, while B-vitamins are indeed important for neurological health, there is limited direct scientific evidence from controlled studies to support the use of brewer's yeast specifically for treating nervousness or anxiety. Most modern research focuses on B-vitamin supplementation in general, rather than brewer's yeast itself, and results are mixed regarding their efficacy in managing mood or anxiety disorders. Thus, while brewer's yeast is traditionally used to support nervous system health and alleviate nervousness due to its nutritional profile, this use is not strongly backed by clinical research. The evidence is rated as 2, reflecting historical use with limited scientific substantiation.
