While toxicity is rare, excessive intake of certain B vitamins (particularly B or B) from multiple sources could increase the risk of side effects (like niacin flush or peripheral neuropathy)
Similar to probiotics, Postbiotics may exert health benefits through similar mechanisms, such as improved epithelial barrier function, host-microbiota modulation, immune response modulation, systemic metabolism modulation, and nervous system signaling (256, 257)
An overdose of vitamin B12 through diet is hardly possible and also not known, since the required transport protein IF (intrinsic factor) and absorption via the intestinal mucosa are two major barriers
The reasoning follows a consistent framework
