Official title
Impact of Lp299v on Vascular Aging in Healthy Adults
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Emerging data suggest the gut microbiota regulates multiple mechanisms related to vascular aging, but no intervention targeting the gut microbiota has been tested in older adults without cardiovascular risk factors or cardiovascular disease. Early human data suggest an increase in potentially pathological gut metabolites such as trimethylamine-N-oxide (TMAO) are associated with older age, increased vascular stiffness, increased oxidative stress, and reduced nitric oxide (NO) bioavailability as evidenced by impaired endothelium-dependent vasodilation. Based on this data, the investigators hypothesize that supplementation with Lp299v will reverse human vascular aging in healthy older adults free of known traditional cardiovascular risk factors.
