Why Combine CoQ10 and L-Carnitine vitamin supplements?The synergy of the combination of Acetyl L- Carnitine and COQ10 vitamins is linked to the role they have in the biochemistry of energy. Both are naturally occurring substances that are found in virtually all cells of the human body and represent important factors in metabolic energy enhancement. This best combination of L-carnitine and CoEnzyme COQ10 vitamin supplement not only supports the metabolism of fats, carbohydrates and proteins, supports the production of ATP (adenosine triphosphate), the "energy of life". A deficiency of L-Carnitine and CoQ10 may be associated with deficiencies in energy.Quite simply, L-Carnitine delivers the fuel and CoQ10 helps burn it. By combining these supplements together, the best utilization of effeciency of CoQ10 increases significantly, up to three times the effectiveness. As we age, the production of both CoQ10 and L-Carnitine decrease and relative deficiencies may appear overtime. Although abundant in grains, legumes and most meat, CoQ10 is often destroyed through processing and cooking. L-Carnitine, while available in meats, must be synthesized by the body from the amino acids lysine and methionine, and B1, B6, niacin, vitamin C and iron.
Coenzyme Q10 is used by cells to produce energy needed for cell growth and maintenance. CO Q10 is also used by the body as an antioxidant. An antioxidant is a substance that protects cells from chemicals called free radicals. Free radicals are highly reactive chemicals that can damage important parts of cells, including deoxyribonucleic acid (DNA). (DNA is a molecule inside cells that carries genetic information and passes it from one generation to the next.) This damage may play a role in the development of cancer.
Co-Q10 may prove to be the ultimate weapon against aging, a growing number of scientist believe that the aging process is the result of a slowdown in energy production of the cells. as mitochondria age, it shows wear and tear over time, just like the rest of your body.Some scientist beleive that taking Coq10 with a combination of L-Carnitine, may increase energu production in cells helping to prevent age related slowdown.
Studies have yielded information about how CoQ10 works in the body to produce energy and act as an antioxidant. Some studies have suggested that coenzyme Q10 stimulates the immune system and increases resistance to disease. In part because of this, researchers have theorized that Co Q10 may be useful as an adjuvant therapy for cancer. (Adjuvant therapy is treatment given following the primary treatment to enhance the effectiveness of the primary treatment.)
The first study, which was conducted in Denmark, involved 32 breast cancer patients. All of the participants received coenzyme Q10 and several other dietary supplements, in addition to their standard treatment. Six of the patients were reported to show some signs of remission (disappearance of the signs and symptoms of cancer). However, the data were not complete, and information that suggested remission was presented for only three of the six patients. All of the participants reported decreased use of painkillers, improved quality of life, and absence of weight loss during treatment.
In a followup study, one new patient and one of the patients who had a reported remission were treated with high doses of Coq10 for 3 to 4 months. Both of the patients had breast cancer remaining after surgery. After the period of high-dose coenzyme Q10 supplementation, both patients appeared to experience complete regression (decrease in the size or extent) of their remaining cancer. However, it is not known which of the six patients with a reported remission in the first study took part in the followup study.
In a third study conducted by the same researchers, three breast cancer patients were given high-dose coenzyme Q10 and followed for 3 to 5 years. One patient had complete remission of cancer that had spread to the liver, another had remission of cancer that had spread to the chest wall, and the third had no evidence of breast cancer remaining after surgery.
There have also been anecdotal reports that coenzyme Q10 has increased the survival of patients with cancers of the pancreas, lung, colon, rectum, and prostate. (Anecdotal reports are incomplete descriptions of the medical and treatment history of one or more patients.) The patients described in these reports also received treatments other than coenzyme Q10, including chemotherapy, radiation therapy, and surgery.
Patients should talk with their health care provider about possible interactions between coenzyme Q10 and prescription drugs they may be taking. Certain drugs, such as those that are used to lower cholesterol or blood sugar levels, may reduce the effects of CoQ10. Coenzyme Q10 may also alter the body�s response to warfarin (a drug that prevents the blood from clotting) and insulin.
Parkinson's Disease is a chronic, progressive neurological disease that affects about 500,000 people in the United States. It results from the loss of brain cells that produce the neurotransmitter dopamine and causes tremor, stiffness of the limbs and trunk, impaired balance and coordination, and slowing of movements. Patients also sometimes develop other symptoms, including difficulty swallowing, disturbed sleep, and emotional problems. PD usually affects people over the age of 50, but it can affect younger people as well. While levodopa and other drugs can ease the symptoms of PD, none of the current treatments has been shown to slow the course of the disease.
The investigators believe CoQ10 works by improving the function of mitochondria, the "powerhouses" that produce energy in cells. Coenzyme Q10 is an important link in the chain of chemical reactions that produces this energy. It also is a potent antioxidant a chemical that "mops up" potentially harmful chemicals generated during normal metabolism. Previous studies carried out by Dr. Shults, Richard Haas, M.D., of UCSD and Flint Beal, M.D., of Cornell University have shown that CoQ10 levels in mitochondria from PD patients are reduced and that mitochondrial function in these patients is impaired. Animal studies have shown that coenzyme Q10 can protect the area of the brain that is damaged in Parkinson's Disease. Dr. Shults and colleagues also conducted a pilot study with Parkinson's Disease patients which showed that consumption of up to 800 mg/day of coenzyme Q10 was well-tolerated and significantly increased the level of coenzyme Q10 in the blood.
All of the patients who took part in the new study had the three primary features of Parkinson's Disease tremor, stiffness, and slowed movements and had been diagnosed with the disease within 5 years of the time they were enrolled. After an initial screening and baseline blood tests, the patients were randomly divided into four groups. Three of the groups received coenzyme Q10 at three different doses (300 mg/day, 600 mg/day, and 1,200 mg/day), along with vitamin E, while a fourth group received a matching placebo that contained vitamin E alone. Each participant received a clinical evaluation 1 month later and every 4 months for a total of 16 months or until the investigator determined that the patient needed treatment with levodopa. None of the participants or the study investigators knew which treatment each patient had received until the study ended. The investigators found that most side effects of coenzyme Q10 were mild, and none of the patients required a reduction of their dose. The percentage of people receiving CoQ10 who reported side effects was not significantly different from that of the placebo group. During the study period, the group that received the largest dose of coenzyme Q10 (1,200 mg/day) had 44 percent less decline in mental function, motor (movement) function, and ability to carry out activities of daily living, such as feeding or dressing themselves. The greatest effect was on activities of daily living. The groups that received 300 mg/day and 600 mg/day developed slightly less disability than the placebo group, but the effects were less than those in the group that received the highest dosage of coenzyme Q10.
The groups that received CoQ10 also had significant increases in the level of coenzyme Q10 in their blood and a significant increase in energy-producing reactions within their mitochondria.
The results of this study suggest that doses of coenzyme Q10 as high as 1,200 mg/day are safe and may be more effective than lower doses, says Dr. Shults. The findings are consistent with those of a recently published study of patients with early Huntington's disease � another degenerative neurological disorder � that showed slightly less functional decline in groups that received 600 mg/day of coenzyme Q10.
In this migraine headache test, all participants knew that they were taking Coenzyme CoQ10. There were no adverse side-effects with the use of coenzyme Q10.

The principal food dietary sources of carnitine are meat and dairy products, but to obtain therapeutic dosages a supplement is necessary.
Lesser evidence suggests that it may be helpful for a condition called intermittent claudication (pain in the legs after walking due to narrowing of the arteries), as well as congestive heart failure. In addition, a few studies suggest that carnitine may be useful for cardiomyopathy.
Carnitine may also be helpful for improving exercise tolerance in people with chronic pulmonary obstruction disease (COPD), more commonly known as emphysema.
Warning: You should not attempt to self-treat any of these serious medical conditions, nor should you use carnitine as a substitute for standard drugs.
One study found evidence that acetyl-L-carnitine is helpful for Peyronie's disease, a condition affecting the penis.
Some studies have found evidence that one particular form of carnitine, acetyl-l-carnitine, might be helpful in Alzheimer's disease, but the two most recent and largest studies found no benefit. This form of carnitine has also been investigated for treatment of depression in the elderly.
A genetic condition called fragile X syndrome can cause behavioral disturbances such as hyperactivity, along with mental retardation, autism, and alterations in appearance. A preliminary study of 17 boys found that acetyl-L-carnitine might help to reduce hyperactive behavior associated with this condition.
Additionally, a preliminary study suggests that carnitine may be useful for improving blood sugar control in individuals with type 2 (adult-onset) diabetes. It also might help prevent diabetic cardiac autonomic neuropathy (injury to the nerves of the heart caused by diabetes). Weak evidence suggests that carnitine may be able to improve cholesterol and triglyceride levels, and also help individuals with degeneration of the cerebellum (the structure of the brain responsible for voluntary muscular movement). One very small study suggests carnitine may be helpful for reducing symptoms of chronic fatigue syndrome. One study suggests that carnitine may be of value for treating hyperthyroidism.
Uncontrolled studies suggest that L-carnitine or acetyl-L-carnitine may be helpful for improving sperm function. Weak evidence also suggests that carnitine may be helpful for decreasing the toxicity of AZT (a drug used to treat AIDS).
Carnitine is widely touted as a physical performance enhancer, but there is no real evidence that it is effective and some research indicates that it does not work. Little to no evidence supports other claimed benefits such as treating irregular heartbeat, Down's syndrome, muscular dystrophy, and alcoholic fatty liver disease.
Another trial that did use a double-blind, placebo-controlled design tested L-carnitine in 52 individuals with angina, and found evidence of benefit. In addition, several small studies (some of them double-blind) tested propionyl-L-carnitine for the treatment of angina, and also found evidence of benefit.
A 12-month double-blind placebo-controlled trial of 485 patients with intermittent claudication evaluated the potential benefits of propionyl-L-carnitine. Participants with relatively severe disease showed a 44% improvement in walking distance as compared to placebo. However, no improvement was seen in those with mild disease. Another double-blind study followed 245 people and also found benefit.
Similar results have been seen in most but not all other studies of L-carnitine or propionyl-L-carnitine. Propionyl-L-carnitine may be more effective for intermittent claudication than plain carnitine.
A double-blind placebo-controlled trial that enrolled 431 participants for 1 year found no significant improvement at all in the group treated with acetyl-L-carnitine. A close look at the results appeared to suggest some benefit in individuals who developed Alzheimer's disease at a particularly young age. However, when this possibility was tested in a 1-year double-blind placebo-controlled trial of 229 patients with early-onset Alzheimer's, no benefits were seen.
Treatment of benign goiter generally consists of taking thyroid hormone pills. This causes the thyroid gland to become less active, and the goiter shrinks. However, there may be undesirable effects as well. Symptoms of hyperthyroidism (too much thyroid hormone) can develop, including heart palpitations, nervousness, weight loss, and bone breakdown.
A double-blind, placebo-controlled trial found evidence that use of L-carnitine could alleviate many of these symptoms. This 6-month study evaluated the effects of L-carnitine in 50 women who were taking thyroid hormone for benign goiter. The results showed that a dose of 2 or 4 g of carnitine daily protected participants' bones and reduced other symptoms of hyperthyroidism.
Carnitine is thought to affect thyroid hormone by blocking its action in cells. This suggests a potential concern: Carnitine might be harmful for people who have low or borderline thyroid levels to begin with. This possibility has not been well explored as yet.
Individuals on dialysis should not receive this (or any other supplement) without a physician's supervision. The maximum safe dosages for young children, pregnant or nursing women, or those with severe liver or kidney disease have not been established.
