## What it is

Gut-microbiome tests sequence the DNA (or RNA activity) of the trillions of microbes in the digestive tract, profiling which species are present, their relative abundance and, in metatranscriptomic tests, what they are actively doing.

## What the human evidence shows

The composition and diversity of the gut microbiota shift with age and influence immunity, metabolism and systemic inflammation. The aging gut microbiome is increasingly viewed both as a marker of biological age and as a modifiable target for anti-aging interventions through diet and probiotics.

## The research

### Cited studies

1. **Gut microbiota: A player in aging and a target for anti-aging intervention**
   Ageing Research Reviews 2017 · [PMID 28109835](https://pubmed.ncbi.nlm.nih.gov/28109835/) · [DOI 10.1016/j.arr.2017.01.001](https://doi.org/10.1016/j.arr.2017.01.001)

   > Aging-associated alterations in composition, diversity and functional features of intestinal microbiota are well-described, and the gut microbiota is a promising target for anti-aging intervention.
