Based on the existing research, certain yeast-derived supplements, particularly those containing Saccharomyces cerevisiae, show promise in managing allergies and asthma-related symptoms. A study demonstrated that perinatal administration of this yeast in mouse models significantly reduced airway hyperresponsiveness and inflammatory markers, indicating its potential for asthma prevention when given early in development [1]. Additionally, another study found that bread fermented with UFMG A-905 could alleviate asthma-like symptoms in mice exposed to allergens, supporting its use in managing allergic reactions [3].
Moreover, the yeast-derived postbiotic EpiCor has been shown to effectively lessen cold and flu symptoms in children, which suggests enhanced immune function that could be beneficial in allergic conditions as well [2]. However, while these studies highlight the potential benefits of yeast-based supplements for allergy management, more research, particularly in human trials, is necessary to fully establish their efficacy and safety. Overall, these findings indicate a growing area of interest in the use of yeast-derived supplements for allergy-related issues, warranting further exploration.
