GLOSSARY

Microflora is a historical term for microbiota, best clarified by the organisms and location intended.

For example, read a post-travel or post-diet sample with the same period's history; a teammate difference or striking percentage alone is neither a supplement target nor proof of lost readiness.

Microbiota refers to organisms in an environment; microbiome can also include their genes and ecological setting, depending on the definition. Gut communities contain more than bacteria, and intestinal regions differ. Stool offers a useful view of part of this system, not a complete map of small-intestinal or mucosal populations. Define the sample and terminology before interpreting a report as a description of the entire body.

Microbes interact with substrates, chemistry, the host and one another, rather than forming a simple good-versus-bad list. Cooperation, competition and use of another organism's products coexist. A species' effect depends on strain, location and context. In sports nutrition, a varied tolerable dietary pattern is more useful than maximizing one bacterial name without human evidence. Ecological relationships cannot be inferred from a single abundance measurement alone.

Composition identifies detected groups; functional potential concerns genetic capacity, while activity concerns what is actually expressed or produced. Different communities can share functions. A gene's presence does not guarantee a particular metabolite output. Organism names alone therefore establish neither extra usable energy nor improved absorption, strength or recovery. Distinguish taxonomic detection, measured activity and meaningful human outcomes when assessing a microbiome claim.
