02 Mar 2020 --- Seasonal interest in bolstering immunity has been heightened this year as coronavirus (COVID-19) continues to spread throughout the world. While experts warn that some may take advantage of consumers by peddling “miracle cures,” some members of the industry have highlighted how a strong immune system is one element of fighting viruses. Kerry notes that clinical research has demonstrated its yeast beta-glucan Wellmune may help support upper respiratory tract infections, while Cymbiotika’s new silver supplement is touted as providing immune defense. However, the US-based Center for Science in the Public Interest (CSPI) has warned of other silver dietary supplements that are misleading people seeking COVID-19 cures.
