03 Sep 2020 --- Tapping into the growing consumer demands around immunity, two US-based companies have launched products in this space. Previously focusing solely on cannabidiol (CBD) beverages, Weller now offers Sparkling Immunity, a carbonated water featuring elderberry to deliver essential vitamins and minerals. Meanwhile, Life Extension has introduced Florassist Immune and Nasal Defense, which is a probiotic formula developed after observing that factory workers at a yeast fermentation plant had better attendance than their office counterparts.
