Journal: Mechanisms of Ageing and Development

 Publication Date: 10/2005

 Summary: Non-enzymic protein glycosylation (glycation) plays important roles in ageing and in diabetes and its secondary complications. Dietary constituents may play important roles in accelerating or suppressing glycation. It is suggested that carnivorous diets contain a potential anti-glycating agent, carnosine (β-alanyl-histidine), whilst vegetarians may lack intake of the dipeptide. The possible beneficial effects of carnosine and related structures on protein carbonyl stress, AGE formation, secondary diabetic complications and age-related neuropathology are discussed.

Key Takeaways

Carnosine is a nutrient only found in animal meat. This nutrient may play a role in keeping proteins and enzymes in your body functioning properly by preventing sugar molecules from sticking to them, which impairs their function.

Journal: Annals of the New York Academy of Sciences

Publication Date: 05/2006

Summary: Carnosine has the potential to suppress many of the biochemical changes (e.g., protein oxidation, glycation, AGE formation, and cross‐linking) that accompany aging and associated pathologies. Glycation, generation of advanced glycosylation end‐products (AGEs), and formation of protein carbonyl groups play important roles in aging, diabetes, its secondary complications, and neurodegenerative conditions. It is suggested that carnivorous diets could be beneficial because of their carnosine content, as the dipeptide has been shown to suppress some diabetic complications in mice. It is also suggested that carnosine’s therapeutic potential should be explored with respect to neurodegeneration.

Key Takeaways

Carnosine again showing suppression of complications associated with aging, diabetes, and neurodegenerative disorders.

Summary: l-carnitine supplementation at doses above 2 g/d has favorable effects on patients’ lipid profiles, but is modulated on participant health and route of administration.

Key Takeaways

Supplementing with l-carnitine, a nutrient only found in meat, can have positive effects of blood lipids.

Journal: Complementary Therapies in Medicine

Publication Date: 06/2019

Summary: Weight and BMI decreased in both groups, but significantly more in l-carnitine group, while diastolic blood pressure and triglycerides decreased significantly more in non-l-carnitine group compared between groups, blood glucose did not differ significantly between groups. l-carnitine can boost the positive effects of fasting therapy on weight loss and maintain the stability of blood pressure.

Key Takeaways

L-carnitine supplementation can improve weight loss and have positive effects on blood pressure and triglycerides.

Why Does Supplementation With Nutrients Found In Meat Improve Health?

The effect of l-carnitine supplementation on lipid profile and glycaemic control in adults with cardiovascular risk factors: A systematic review and meta-analysis of randomized controlled clinical trials

October 3, 2019 No Comments

URL: https://www.sciencedirect.com/science/article/pii/S026156141930038X

Journal: Clinical Nutrition

Publication Date: 02/2019

Summary: This meta-analysis showed that l-carnitine supplementation could improve lipid profile levels, particularly in doses more than 1500 mg/day. More RCTs with large sample sizes, focusing on gut microbiome profiles and dietary patterns are needed to better understand the effect of l-carnitine on patients with cardiovascular risk factors.

Key Takeaways

L-carnitine is a nutrient only found in meat that when given as a supplement has positive effects on blood lipids.

Carnosine and advanced glycation end products: a systematic review

October 3, 2019 No Comments

URL: https://www.ncbi.nlm.nih.gov/m/pubmed/29858687/

Journal: Amino Acids

Publication Date: 09/2018

Summary: Carnosine has anti-glycating properties, and may hinder the formation of protein carbonyls and the cross-links induced by reduced sugars; however, there were few human studies.

Key Takeaways

Excessive dietary intake of carbohydrates can lead to the glycation of proteins. Glycation occurs when a carbohydrate attaches itself to a protein and impairs its ability to function normally. Carnosine is a nutrient only found in meat products that may have the ability to prevent glycation from occuring.

Journal: Comprehensive Reviews in Food Science and Food Safety

Publication Date: 07/2018

Summary: Carnosine has been shown to prevent AGE formations through reduction of blood glucose, prevention of early glycation, and even reversing previously formed AGEs.

Key Takeaways

Carnosine is a nutrient found only in meat that prevents sugars from binding to proteins and impairing the protein's function.

Journal: Life Science

Publication Date: 02/2018

Summary: Exogenous carnitine administration through dietary and intravenous routes serves as a suitable protective strategy against ventricular dysfunction, ischemia-reperfusion injury, cardiac arrhythmia and toxic myocardial injury that prominently mark CVD. Additionally, carnitine reduces hypertension, hyperlipidemia, diabetic ketoacidosis, hyperglycemia, insulin-dependent diabetes mellitus, insulin resistance, obesity, etc. that enhance cardiovascular pathology. These favorable effects of l-carnitine have been evident in infants, juvenile, young, adult and aged patients of sudden and chronic heart failure as well.
