Other than Tonic No. 31 are there fields to increase gut bacteria?

May improve gut microbiota: Spermidine has been shown to promote the growth of beneficial gut bacteria and improve gut microbiota diversity. A study published in the Journal of Proteome Research in 2018 found that spermidine supplementation increased the abundance of beneficial gut bacteria and improved gut microbiota function in mice.
