FM in men is usually less important for function, bone density, glucose level, and cognitive function than in women. Changes in muscle and fat distribution according to aging and their correlation with health outcomes differ according to sex. Muscle mass may not always be favorable, and fat mass may not always be unfavorable in older adults.

Gut microbiota-derived metabolite trimethylamine N-oxide (TMAO) can be metabolized from phosphatidylcholine, choline, and l-carnitine and may play an important role in CVD etiology. Thus, this systematic review aimed to evaluate the effect of probiotics to mitigate TMAO concentrations by gut microbiota modulation. A systematic review was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis protocol from databases PubMed, Web of Sciences, CENTRAL, and Scopus. Controlled intervention studies published until January 3, 2022, with a population at cardiovascular risk were included. The risk of bias was assessed by RoB 2.0 and SYRCLE's for humans and animals' studies, respectively. The search in the database returned 5389 studies, of which 8 matched all criteria to final qualitative analysis. Four studies were controlled trials with humans (total population = 115) and 4 were animal model studies. The body of evidence on the use of probiotics to reduce TMAO concentrations shows that only a few strains have this beneficial effect. This review can conclude that
