Coenzyme Q10 (150 mg)

Coenzyme Q10 (CoQ10), is a fat soluble anti-oxidant nutrient that is found in a variety of foods in relatively small quantities. The typical daily dietary intake ranges between 3-5 mg; mainly from meat, fish and poultry. ⁽¹⁾ The amounts provided from the diet are quite low and far from the amounts required for therapeutic effects.
CoQ10 is an integral component of oxidative phosphorylation. The mitochondria of cells require CoQ10 to convert energy from food into the main cellular fuel known as adenosine triphosphate (ATP).
CoQ10 may help the heart during times of stress by improving cardiac energy utilization. CoQ10 acts as an antioxidant due to its capacity to increase endogenous (internally produced) antioxidant enzymes and reduce lipid peroxidation (damage to lipids and fatty cell membranes).
Favourable modifications in plasma lipid concentrations are linked to the intake of CoQ10, thereby reducing potential risk.
Clinical evidence shows that supplemental intake of CoQ10 benefits conditions associated with cellular energy and antioxidant abnormalities (including mitochondrial encephalomyopathies, myoclonic epilepsy with lactic acidosis and stroke like episodes, Kearns-Sayre syndrome, etc.) and congestive heart failure. ⁽³’⁴⁾ Improvements in blood pressure and protection from myocardial infarctions have also been associated with supplementation of CoQ10. ⁽⁵’⁶⁾

Preliminary evidence shows that CoQ10 may be beneficial for the management of diabetes; however, research is still warranted to confirm this effect.

Daily supplements of CoQ10 may boost antioxidant defences and reduce markers of oxidative stress in people with atherosclerosis, or hardening of the arteries.

According to a new study from Taiwan published in the October, 2011 edition of Nutrition titled “Coenzyme Q10 supplementation reduces oxidative stress and increase antioxidant enzyme activity in patients with coronary artery disease”.

The authors reported: “A daily CoQ10 dose of 150 mg was associated with 29% lower levels of malon-dialdehyde (MDA - a reactive carbonyl compound and a well-established marker of oxidative stress) after eight weeks, compared with the placebo group”.

MOLECULAR EVENTS UNDERLYING INFERTILITY

Dr. Robert Casper, Senior Scientist at the Lunenfeld-Tanenbaum Research Institute of Mount Sinai Hospital and Medical Director of the Toronto Centre for Advanced Reproductive Technology (TCART) and Dr. Andrea Jurisicova, Investigator at the Lunenfeld-Tanenbaum Research Institute, and an Associate Professor of Obstetrics and Gynaecology at the University of Toronto are investigating the process of mitochondrial activity in oocytes of older females.

By studying the quality of oocytes (in an animal model) in older versus younger mothers, the duo has found that mitochondria, the energy-producing power stations of cells, become less metabolically active with age, putting the offspring at greater risk of developing obesity and metabolic syndrome, and predisposing them to diabetes.

Administration of coenzyme Q10—a vitamin-like substance found in mitochondria—can reverse the effects of mitochondrial changes in oocytes, improve fertility, and perhaps reduce the risk of chromosomal abnormalities.

“Supplementing the diet with Coenzyme Q10 appears to enhance mitochondrial activity and boost the quality of oocytes,” says Dr. Casper.

Summary

Mitochondrial dysfunction has been definitively linked to virtually all killer diseases of ageing, from Alzheimer’s disease and type 2 diabetes to heart failure.

Researchers have recorded evidence of greater mitochondrial damage in the brain cells of humans over 70 compared to those in their early 40s. The health and function of these cellular energy generators is now considered so vital that many scientists believe mitochondrial longevity determines overall longevity in ageing humans.

In a revolutionary advance, an essential coenzyme called Pyrroloquinoline Quinone or PQQ has been shown to induce mitochondrial biogenesis—the growth of new mitochondria in ageing cells!

While CoQ10 optimizes mitochondrial function, PQQ activates genes that govern mitochondrial reproduction, protection, and repair. PQQ also affords potent cardio protection and optimal defense against neuronal degeneration. Published studies show that 20 mg of PQQ plus 300 mg of CoQ10 may reverse age-related cognitive decline in ageing humans.

Phosphatidylcholine (800 mg)

A more effective delivery system (release in the small intestine) includes the use of fat soluble emulsifying agents such as phosphatidylcholine to increase the bio-availability of CoQ10.
It was demonstrated that the bio-availability of sitostanol, a phytosterol compound, was increased when formulated with lecithin.⁽¹⁰⁾
Another study showed that absorption of the fat soluble carotenoid lycopene was enhanced with the enteral administration of phosphatidylcholine.⁽¹¹⁾

Bioavailability

Given the therapeutic potential of CoQ10, supplemental forms are being explored for maximum bioavailability. Typical pre-supplemental plasma concentrations of CoQ10 in healthy adults range between 0.50-0.52 micrograms/ml. Three months of supplemental intake (120 mg daily) can potentially elevate these levels three fold.⁽⁸⁾

Bio-availability Co-factors

The fat soluble nature of CoQ10 requires dietary fat to promote its absorption. Lipids associated with fat soluble nutrients induce the release of bile and promote emulsification (micelle suspensions) to facilitate absorption via the small intestine. ⁽⁹⁾
A recent study shows that CoQ10 in an oil suspension gave better bio-availability; likely due to its fat soluble nature. ⁽⁷⁾ Naturally occurring emulsifiers, such as phosphatidylcholine (lecithin) are known to support this process.

Phosphatidylcholine (800 mg)

A more effective delivery system (release in the small intestine) includes the use of emulsifying agents such as phosphatidylcholine to increase the bio-availability of CoQ10.

It was demonstrated that the bio-availability of sitostanol, a phytosterol compound, was increased when formulated with lecithin. ⁽¹⁰⁾
Another study showed that absorption of the fat soluble carotenoid lycopene was enhanced with the enteral administration of phosphatidylcholine. ⁽¹¹⁾

Pyridoxyl-5'-Phosphate (10 mg)

Pyridoxyl-5'-Phosphate (PLP), the active form of vitamin B6 is included because it further enhances plasma concentrations of CoQ10. PLP is essential to the endogenous (internal) synthesis of CoQ10.
It is known that the endogenous bio-synthesis of CoQ10 from the precursor tyrosine is dependent on adequate PLP levels. Research has found that individuals with low plasma CoQ10 status are also low in plasma PLP. ⁽¹⁾

Supplemental intake of CoQ10 formulated with phosphatidylcholine and PLP will enhance plasma concentrations of CoQ10 thereby improving its therapeutic action.

DRcaps, plus the combination of nutrients in this formula makes it the most bio-available form of CoQ10 available.
In addition, this combination of nutrients may also help reduce the levels of plasma homocysteine (an independent marker for cardiovascular disease risk), since PLP and phosphatidylcholine support the methylation pathways responsible for lowering homocysteine levels.
