Humans can’t make Vitaminc

Research has shown that vitamin C supplementation can increase the abundance of beneficial bacteria in the gut microbiome, particularly those of the genus Bifidobacterium. Studies have found that vitamin C can significantly increase the relative abundance of Bifidobacterium and affect various species, contributing to the modulation of the gut microbiome and potentially offering therapeutic benefits.
Moreover, vitamin C has been observed to modulate the gut microbiome, which may help protect against severe outcomes associated with viral illnesses, including SARS-CoV-2 infection. Additionally, vitamin C can increase microbial alpha diversity and fecal short-chain fatty acids, further supporting its role in gut health.
