L-Carnitine and CoQ10 combination for mitochondrial energy and heart health

In our earlier article we have discussed with the roles of Conenzyne Q10 in energy generation and in protection of Heart or cardiovascular disease. Conenzyne Q10 helps cell powerhouse mitochondria in generating energy from carbohydrates and fatty acids. Conenzyne Q10 not only support the energy generation process like a spark but also additionally acts as a powerful antioxidant in mitochondrial membranes.(1,2)On the other hand L-carnitine a naturally occurring amino acid derivative involves in transporting fatty acid to mitochondria. So do they work in synergy? Does combination of L Carnitine and COQ10 work better for mitochondrial energy and heart health?

L-Carnitine and CoQ10 combination for mitochondrial energy and heart health

What is L-Carnitine?

L-Carnitine is a naturally occurring amino acid derivative is found in nearly all cells of the body. The name carnitine is derived from the Latin carnus or flesh. (3)Food sources include animal and milk products.

The main role of L-Carnitine involves as mitochondrial function and energy generation. It helps in transporting fats (long-chained fatty acids) to mitochondria to use as energy.(4) L-Carnitine may help in improving mitochondrial function and thus prevents diseases as well as promote healthy aging.(5)   

L-carnitine in heart function and cardiovascular health

Several studies examined the effectiveness of L. Carnitine in management of blood flow including heart tissue. L. Carnitine levels were low in heart failing muscle. L. Carnitine reduces risk of heart attack by counteracting the toxic effect of high levels of free fatty acids and by improving carbohydrate metabolism. (3,6)

L-carnitine in heart function and ability to perform exercise

Study showed people who took L-carnitine after suffering heart attack had significant lower mortality rate than controlled. They found 1.2 percent mortality rate in L-carnitine taker compared to 12.5 percent in the control group. (7) One randomised placebo controlled study on people with heart failure found people taking 2 g of L-carnitine had 3 years higher survival rate than placebo.(8)L-carnitine also improves ability to perform exercise in people with angina or chest pain without pain. (9,10)

L-carnitine as antioxidant defense and improvement of endothelial function

Oxidation of lipid promotes narrowing of blood vessel as well as development of atherosclerosis is recognized as major risk factor of heart disease. Increased oxidative stress is associated with all cardiovascular risk factors. Oxidative stress plays an important role in platelet activation and endothelial or inner line of blood vessel dysfunction.

L-Carnitine and CoQ10 combination for mitochondrial energy and heart health

Study showed Carnitines incubation significantly increased HO-1 as well as endothelial nitric oxide gene and protein expression. As HO-1 and nitric oxide are known as antioxidant, antiproliferative and anti-inflammatory, their increased expression would be expected to protect from oxidative stress. (11) Release of nitric oxide in endothelial or inner line of blood vessel keeps moisten lining of blood vessel which improves health of blood vessels and circulation. And therefore release of nitric oxide improves endothelial function as well as prevent plaque formation or atherosclerosis. Vitro and animal studies as well as some human studies favor the preventive effects of L-carnitine and its derivatives on endothelial dysfunction and platelet aggregation. (12)

In human clinical studies apart from favorable results in lipid profiles L-carnitine supplementation significantly reduced oxidative stress as well as increased antioxidant enzymes activities in people with heart disease.(13,14) L-carnitine also significantly decreased inflammatory response C reactive protein of CRP in meta analysis.(15)

A 2013 meta analysis of controlled trials published in Mayo Clinic Proceedings concluded that L-carnitine reduces 27% in all-cause mortality, a 65% in abnormal heartbeats, and a 40% reduction in chest pain in peoples experiencing an acute heart attack.(16)

L-Carnitine and CoQ10 combination for mitochondrial energy and heart health

Your heart is an organ with most metabolically active tissues that works constantly without any rest for your whole life. That’s why your heart tissues need proper energy as well as other supports. Apart from other roles both Coenzyme Q10 and L-carnitine preserves mitochondrial function as well as involves in mitochondrial energy generation.(17) 

In animal study CoenzymeQ10 and L-carnitine supplementation has beneficial effect on cholesterol lowering drug stain induced pancreatic mitochondrial toxicity.(18) Researchers indicates the combination of L- carnitine and Coenzyme Q10 has shown more beneficial effect in mitochondrial disorder than using separately. (19,20) In a Mini Review and Clinical Trial CoQ10, L-Carnitine and other cocktail antioxidants like vitamin C, B, E and zinc and selenium had increased total serum antioxidant status in people with HIV. (21)

In most lifestyle intervention program increasing antioxidant intake seems to improve quality of life. Studies demonstrated being potent antioxidant both CoenzymeQ10 and L-carnitine improves quality of life in people with heart failure, cardiovascular and also kidney disease. Research published in the Journal of Cardiovascular and Thoracic Research indicates that supplementation with coenzyme Q 10 and L-carnitine improved the well-being of patients with heart disease. They found supplementing CoQ10 150 mg/d and L-carnitine 1200 mg/d for three months showed a significant improvement in both physical and emotional quality of life. The researchers suggested that the coenzyme Q 10 and L-carnitine may have positive effect in muscle as well as red blood cells (22, 23)

Apart from that the combination also showed beneficial effects in migraine pain in clinical study. (24)

Daily dose of coenzyme Q10

Typical dose of CoQ10 ranges 90–200 mg per day  depending upon varying health condition. Side effects appears as rare and mild like diarrhea, nausea, and heartburn in some cases. Pregnant, lactating as well as individual under medication should consult with healthcare provider first.

Daily dose of L-Carnitine

Safe daily dose of L-carnitine ranges up to 2 g per day with two to three divided dose. (25) But higher dose may be risky. Similarly pregnant, lactating as well as individual with specific health condition should consult with healthcare provider before application.
