PRODUCT DISCUSSION
Physiologics' Coenzyme Q-10 & L-Carnitine softgels provide two powerful
ingredients to support heart health. CoQ-10 is an essential component of the
mitochondrial electron transport chain, vital for the production of adenosine
triphosphate (ATP) required for virtually every cellular process. By supporting
the normal physiology of the heart, CoQ-10 promotes healthy circulation through
myocardial tissue. L-Carnitine plays a role in fatty acid metabolism and
supports muscle tissue. Together, these ingredients provide natural support for
cardiovascular health.*
STRUCTURE AND FUNCTION
Coenzyme Q-10 is naturally found in the inner mitochondrial membrane of every
cell in the human body and plays a fundamental role in the production of ATP. In
the mitochondrial respiratory chain, CoQ-10 is the electron acceptor for
mitochondrial complex I and complex II, and donates electrons to complex III
during oxidative phosphorylation. Each pair of electrons in the electron
transport chain must interact with CoQ-10, the rate-limiting component of the
mitochondrial respiratory cycle.*
CoQ-10 is also a component of extra-mitochondrial redox chains, whose function is to remove excess reducing power formed during glycolysis when mitochondrial respiration is decreased. In its reduced form, CoQ-10 is a lipid-soluble antioxidant that readily provides electrons to neutralize superoxide and lipid radicals. Mitochondria are involved in the production of reactive oxygen species, and CoQ-10 scavenges these species to support the cell from oxidative stress that can lead to cell and DNA damage and premature aging.*
In addition, CoQ-10 has membrane stabilizing properties thought to be involved in the phospholipids-protein interaction that aids in the metabolism of prostaglandins. Myocardial calcium-dependent ion channels are stabilized by CoQ-10, which prevents depletion of molecules essential for ATP synthesis. CoQ-10 supports healthy blood flow to cardiac muscle.*
L-Carnitine is synthesized in the liver and kidneys from lysine and methionine, two essential amino acids. Of primary importance is L-Carnitine's obligate role in mitochondrial fatty acid metabolism and energy production. L-Carnitine shuttles long-chain fatty acids across the inner mitochondrial membrane in liver, heart, and skeletal muscle where they are oxidized for the release of free energy. The heart in particular is reliant on L-Carnitine for the production of energy from fat.
INDICATIONS
CoQ-10 is a normal component of the mitochondrial electron transport chain and
supports a healthy cardiovascular system. Endogenous levels of CoQ-10 may
diminish with age, strenuous exercise, and environmental stressors. In addition,
certain regularly prescribed drugs may cause CoQ-10 depletions. L-Carnitine is a
conditionally essential nutrient important for the heart. Supplementing your
clients' diets with Coenzyme Q-10 & L-Carnitine may be an opportunity to
receive a daily supply of these important molecules for heart health.*
HOW CLIENTS MAY BENEFIT
- Increase myocardial CoQ-10 levels for cardiovascular health support.*
- Support cellular levels of ATP, the energy source for all biological processes.*
- CoQ-10 is a powerful antioxidant that fortifies cells from the harmful effects of free radicals.*
- Maintain oxidative phosphorylation for exercise support.*
- L-Carnitine promotes fatty acid metabolism for cellular energy production.*
CLINICAL EVIDENCE
- In one double-blind trial, Tran et al. administered daily doses of 100 mg of CoQ-10 to 80 patients for 17 weeks. Eighty-nine percent experienced support of cardiovascular function, respiratory function and muscle strength support. These benefits lasted during the entire course of treatment.
- In a long-term study, Langsjoen et al. treated 424 patients with CoQ-10 in addition to their normal health regimes and monitored their heart health for eight years. Fifty-eight percent experienced promotion by one New York Heart Association (NYHA) class, 28% by two classes, and 1.2% by three classes.
- In one double blind trial investigating the role of a modified form of Carnitine called propionyl-L-Carnitine (PC) in heart health, 500 mg PC daily was found to promote exercise tolerance by 26% after six months.
SUMMARY
Coenzyme Q-10 plays an essential role in the production of cellular ATP and
cardiovascular health maintenance. Its role as an antioxidant supports tissue
from oxidative damage. L-Carnitine transports fatty acids into mitochondria to
promote cellular energy production. Supplementing your clients' nutritional
regimes with PhysioLogics' Coenzyme Q-10 & L-Carnitine will support their
cellular energy levels, to promote cardiovascular health.*
SUGGESTED DOSAGE
For adults, take one (1) softgel two to four times daily, preferably with meals,
or follow the advice of your health care professional. As a reminder, discuss
the supplements and medications you take with your health care providers.
