L-karnitīns un Q10 sirds veselībai: ko ir svarīgi zināt?

L-Carnitine and Q10 for heart health: what's important to know?

Heart health largely depends on how effectively the body can produce and utilize energy, and this is where substances like L-carnitine and coenzyme Q10 play a significant role. They are often mentioned in connection with an active lifestyle, endurance, and general well-being, especially for people who want to take care of their heart daily. Although the body can synthesize these substances itself, at different stages of life or under increased strain, there may be a need to pay more attention to them in the diet.

Coenzyme Q10

Coenzyme Q10 plays a central role in cellular energy production in mitochondria, is a powerful antioxidant, and neutralizes free radicals, reducing oxidative stress. These effects are particularly important for cells with high energy (ATP) consumption – heart muscle cells.[1] Studies have observed that a decrease in Q10 levels in the body can be associated with impaired heart function, fatigue, and reduced physical endurance, while its supplementary intake can be especially important for people with increased strain on the cardiovascular system.

Why is it recommended?[2]

       The natural synthesis of Q10 in the body decreases with aging.

       Reduced Q10 levels are associated with heart failure and overall fatigue and muscle weakness.

       Supplementary intake of Coenzyme Q10 is particularly suitable for patients with heart failure.

Therefore, in everyday life, especially with increased strain or risk factors for heart health, Q10 is often used as part of a complex approach to supporting the body. Coenzyme Q10 is also included in Cardeon's Balance kit, developed to support the cardiovascular system. 

L-Carnitine

Key benefits:[4]

       L-Carnitine is important for the heart muscle.

       It helps maintain good overall health by promoting the transfer of fatty acid groups across the mitochondrial membrane for cellular energy production.

       If energy supply is poor (for example, after a heart attack or in cases of heart failure), L-carnitine can help heart cells utilize fats more efficiently.

Studies in patients with heart failure have shown that L-carnitine supplementation can improve heart function and reduce symptoms associated with decreased heart activity. A meta-analysis of over 3000 post-myocardial infarction patients found that L-carnitine use was associated with a significant reduction in overall mortality, as well as a significantly lower risk of cardiac arrhythmias and angina pectoris.[5]

Key results:[6]

·       Overall mortality ~27% lower

·       Ventricular arrhythmias ~65% lower

·       Angina symptoms ~40% lower

Considering the importance of L-carnitine in energy metabolism and heart function support, Professor Andris Skride has also included it in the Cardeon product line, which can be purchased separately or as a set: "Cardeon Vital," specifically designed for people with heart failure, low physical endurance, and fatigue.
