Carnosine Supplementation and Cardiovascular Function
A study testing Carnosine supplementation in people with Carnosine, run by Josip Juraj Strossmayer University of Osijek at 1 site in Croatia.
Trial summary
Carnosine is a dipeptide synthesized in the body from β-alanine and L-histidine. It was originally discovered in skeletal muscle where it is present in larger amounts than in other tissues, but it is also found in high concentrations in the brain, heart, and gastrointestinal tissues of humans.

About this study
Official title: Effects of Carnosine Supplementation in Form of Capsules and Functional Food on Cardiovascular Function
Carnosine is a dipeptide synthesized in the body from β-alanine and L-histidine. It was originally discovered in skeletal muscle where it is present in larger amounts than in other tissues, but it is also found in high concentrations in the brain, heart, and gastrointestinal tissues of humans. Although its physiological role has not been completely understood yet, carnosine is a non-enzymatic free-radical scavenger and a natural antioxidant and has anti-inflammatory and neuroprotective properties.
The hypothesis of this research is that the consumption of carnosine supplements in the form of capsules, as well as chicken meat enriched with carnosine (functional food) has a beneficial effect on vascular reactivity measured in different vascular basins, and the lipid profile with a positive effect on the reduction of oxidative stress and inflammatory response in healthy sedentary people. subjects and active athletes measured in different vascular basins.
The main goal of this study is to investigate the influence of carnosine supplement consumption (in the form of capsules and functional food) on vascular and endothelial function in a population of healthy young subjects and active athletes.

Microvascular endothelial function (time frame: 3 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05723939, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Feb 2023.
