Critical Illness is Linked to Levels of Coenzyme Q10

Introduction:
Coenzyme Q10 (CoQ10), also known as ubiquinone, is an essential component of the mitochondria – the energy producing unit of the cells of our body. CoQ10 is involved in the manufacture of ATP, the energy currency of all body processes. Its role in the energy production within our cells is similar to the role of a spark plug in a car engine. Just as the engine cannot function without that initial spark, our cells simply cannot function without CoQ10.

Although CoQ10 can be synthesized within the body, deficiencies do exist as a result of impaired CoQ10 synthesis or increased tissue needs. Examples of diseases that require increased tissue levels of CoQ10 are primarily those that affect the heart, liver, brain, and muscles.

In addition, the elderly in general may have increased CoQ10 requirements as CoQ10 levels are known to decline with advancing age. Finally, cholesterol-lowering drugs, especially statins, are known to lower CoQ10 levels.

Background Information:
People suffering from various critical illnesses such as severe infections, heart attacks or strokes, and cancer typically experience failure of multiple organs. Despite intense investigation for many years, the precise mechanisms underlying the multiple organ failure has baffled researchers. Finally, Harvard-based researchers recently demonstrated that low levels of CoQ10 in patients with severe infection was associated with impaired cellular energy production and decreased ATP throughout their body.

The investigation of CoQ10 levels in these patients was spurred on by a study in rats that showed that even less severe infection was associated with lower CoQ10 levels.

New Data:
A new study by the same group of Harvard researchers was based upon their hypothesis that a broad range of critically ill patients are likely deficient in CoQ10 and that could significantly worsen their condition and lead to organ failure and death. To test this hypothesis, they determined blood CoQ10 levels in 36 critically ill patients in the intensive care unit at Massachusetts General Hospital compared to 18 healthy controls.

Results showed quite clearly that the critically ill patients suffered an approximately 40% drop in CoQ10 levels. The severity of the drop tended to correlate with age as older patients suffered greater reductions than younger patients. There was no association between CoQ10 levels and severity of the illness, but those critically ill patients with higher CoQ10 levels had higher scores on a scale used to assess independence when performing 6 activities required for daily living (bathing, dressing, toileting, moving, continence, feeding).

The authors of the study conclude “our data provide a rationale for further observational and intervention clinical studies to define CoQ10 insufficiency and evaluate the safety and efficacy of CoQ10 supplementation in critically ill patients.”

Comment:
There are some major points to make about this study.

  • The study is a continuation of a line of solid research conducted by Harvard University researchers.
  • The study was conducted at Massachusetts General Hospital, one of the leading hospitals in the world.
  • The study shows a growing openness of conventional medicine to examine the role of physiological aids and dietary supplements even when heroic, life-saving measures are required.
  • The authors clearly believe that CoQ10 supplementation may be of value in enhancing the health of critically ill patients.

6 Natural Ways To Reduce Cholesterol

AssortmentOfFreshVeggiesGarlic469Elevated cholesterol increases the risk of death due to cardiovascular disease. It’s currently recommended that total blood cholesterol (your “bad” cholesterol, LDL, plus your “good” cholesterol, HDL) be less than 200 mg/dl. In addition, your low-density lipoprotein (LDL) cholesterol should be less than 130 mg/dl and your high-density lipoprotein (HDL) cholesterol should be greater than 40 mg/dl in men and 50 mg/dl in women.
Lowering Cholesterol Naturally
Lowering total cholesterol, as well as LDL, is associated with reducing the risk of cardiovascular disease. In high-risk patients, statins are usually prescribed and can produce decreases in total mortality, cardiovascular events and hospitalizations. However, the debate remains whether statin therapy represents the optimal treatment approach to primary prevention of coronary artery disease in patients whose only risk factor is elevated LDL.
There are several natural approaches that have been found to be highly effective for reducing cholesterol. Let’s look at six of them.
1. Low-cholesterol diet 
While the liver is the major source of blood cholesterol, dietary cholesterol can be an important contributor. The best way to reduce cholesterol in your diet is to minimize saturated fat — no more than 10-15 grams per day. Saturated fat is found primarily in animal products, like meat and dairy products. Restrict dietary cholesterol to 300 mg per day. Familiarize yourself with foods that add cholesterol and unhealthy fat to your diet, and find healthier substitutes for these foods.
2. Soluble fiber
Soluble fiber found in legumes, fruit and vegetables is effective in lowering cholesterol levels. To help lower cholesterol, try to eat 35 grams of fiber per day from fiber-rich foods, which, again, you should familiarize yourself with so you’ll get used to buying high-fiber foods. Oat bran and oatmeal are especially good sources of high-value soluble fiber. Natural fiber supplements can also help to boost soluble fiber in your system, if you just aren’t getting enough roughage in your diet.
3. Niacin
Read More
Also known as B3, niacin has been long known to be effective in lowering blood cholesterol levels. In the 1970s, the famous Coronary Drug Project demonstrated that niacin was the only cholesterol-lowering agent to actually reduce overall mortality. Niacin typically lowers LDL cholesterol by 16-23% while raising HDL cholesterol by 20-33%.
The problem with niacin is that it produces skin flushing that typically occurs 20-30 minutes after the niacin is taken. To counteract this, manufactures produced timed-release niacin to reduce flushing, but these formulations have shown to be toxic to the liver. For best results, use intermediate time-release niacin (don’t take any other form of timed-release niacin) should be taken at night, as most cholesterol synthesis occurs during sleep. Start with a dose of 500 mg and increase to 1,500 after two weeks. If after one month of therapy the dosage of 1,500 mg fails to effectively lower LDL cholesterol, increase the dosage to 2,000 mg/day, and then to 3,000 mg a month later if that fails, before discontinuing owing to lack of efficacy.
4. Plant sterols and stanols 
Phytosterols and phytostanols are structurally similar to cholesterol and can act in the intestine to lower cholesterol absorption by displacing cholesterol. Because phytosterols and phytostanols are poorly absorbed, blood cholesterol levels will drop as cholesterol is excreted. These compounds are being added to so-called functional foods (e.g., margarine and other spreads, orange juice, granola bars) and are also available as dietary supplements. Phytosterols and phytostanols are effective in lowering LDL in some people. A meta-analysis of 41 trials showed that an intake of 2 grams of stanols or sterols per day reduced LDL by 10%. The best and safest ways to get these nutrients, though, is by eating foods that are high in stanols and sterols: grains, vegetables, fruits, legumes, nuts and seeds.
5. Pantethine 
Pantethine is the stable form of pantetheine, the active form of vitamin B5, or pantothenic acid. Pantothenic acid is the most important component of coenzyme A, which is involved in the transport of fats to and from cells as well as to the energy-producing compartments within the cell. Pantethine has significant lipid-lowering activity, while pantothenic acid has little, if any, effect on lowering cholesterol. Pantethine at 900 mg per day has been shown to significantly reduce levels of total cholesterol (19%), and LDL cholesterol (21%) while increasing HDL cholesterol (23%). The lipid-lowering effects of pantethine are especially impressive because it has virtually no toxicity compared with conventional lipid-lowering prescription drugs.
6. Garlic 
Garlic appears to be an important protective factor against heart disease and stroke for many reasons. Garlic has been shown to lower blood cholesterol levels even in apparently healthy individuals. In numerous double-blind, placebo-controlled studies of patients with initial cholesterol levels greater than 200 mg/dl, daily supplementation with commercial preparations providing at least 10 mg alliin can lower total serum cholesterol by about 10-12 %.

A Secret for Younger-Looking Skin

young-skinDuring red carpet season, we ogle celebrities at the award ceremonies, examining their skin and hair, along with “who they’re wearing.”

It’s hard not to notice women who have clear, radiant, vibrant-looking skin, which is a sign of good health. While celebrities spend a lot of time improving the appearance of their skin from the outside, the real key to young-looking skin is proper nutrition and healthy habits.

In addition to eating healthfully and exercising, there’s a little-discussed supplement that can help prevent the wrinkling and dryness that contribute to old-looking skin. It’s called hyaluronic acid (HA). HA is a glycosaminoglycan that acts as the intracellular cement or glue of connective tissue. Connective tissue, as the term suggests, serves the function of supporting and binding other tissues. The loose connective tissue holds the skin and internal organs in place, while the fibrous connective tissue includes tendons, ligaments, and cartilage. In essence, hyaluronic acid not only helps to provide the structural framework of connective tissue, it is the actual “glue” that holds our body together.

Maintaining HA in body tissues is an important anti-aging strategy. One of the reasons our skin develops lines and wrinkles is due to the loss of HA. By the time most people reach the age of 70, the HA content in their body has dropped by 80% from when they were 40. After the age of 45 or so, HA levels in the skin begin to plummet.

There is a great deal of evidence that applying HA topically helps prevent wrinkles. But now researchers have discovered that taking hyaluronic acid orally is also beneficial for restoring moisture and youthful suppleness to the skin. Recent clinical studies using oral HA in patients with dry and rough skin have shown that patients given a supplement consisting of purified, bioavailable hyaluronic acid had a significant increase (46%) over baseline values in the moisture content of their skin.

Hyaluronic acid is a substance found in our bodies that’s essential for health, but now we know it’s also a key to beautiful-looking skin.

4 Natural Ways to Reduce Blood Pressure

BeetJuice660Do you want to lower your blood pressure without the harmful side effects of pharmaceuticals? The good news is that there are a number of safe, effective, and natural foods and nutrients that will help you do it.

Over 60 million Americans have high blood pressure, including more than half (54%) of all Americans age 65 to 74 years old and nearly three quarters (72%) of all American blacks in the same age group.

High blood pressure is a major risk factor for a heart attack or stroke. In fact, it is generally regarded as the most significant risk factor for a stroke.
Here are four ways to lower your blood pressure without medication:
1. Drink beet juice.
 
Several recent studies have shown that drinking fresh beet juice can lead to clinically meaningful reductions in blood pressure. For example, a study at the Baker IDI Heart and Diabetes Institute in Melbourne, Australia, found that drinking just 16 ounces of fresh beet juice a day significantly reduced blood pressure in healthy subjects. Beet juice lowered blood pressure within just an hour with a peak drop occurring 3 to 4 hours after ingestion.
Why it works: The decrease in blood pressure is due to the chemical formation of nitrite from the dietary nitrates in the juice. Once in the general circulation, nitrite can be converted to nitric oxide (NO) by the cells that line blood vessels. NO is a powerful dilator of blood vessels, resulting in lower blood pressure.
2. Eat fresh, raw garlic.
 
Garlic has a wide range of well-documented effects, including helping to lower blood pressure. Studies showing a positive effect of garlic and garlic preparations are those that deliver a sufficient dosage of allicin. In double-blind studies with garlic preparations providing a daily dose of at least 10 mg allicin, blood pressure readings dropped with typical reductions of 11 mm Hg for the systolic and 5.0 in the diastolic within a 1 to 3-month period. To get enough allicin, eat 1 to 4 cloves of fresh garlic a day. If you want to avoid garlic breath in public, add minced fresh garlic to your salad dressing in the evening at dinner.
Why it works: All of the beneficial effects of garlic are attributed to its sulfur-containing compounds: allicin, diallyl disulfide, diallyl trisulfide, and others. Allicin is mainly responsible for the pungent odor of garlic. It is formed by the action of the enzyme alliinase on the compound alliin. The enzyme is activated by heat, oxygen, or water. This accounts for the fact that cooked garlic, odorless supplements, “aged garlic preparations,” and garlic oil products produce neither as strong an odor as raw garlic nor nearly as powerful medicinal effects as raw fresh garlic.
3. Drink black tea.
 
An Australian study published in January 2012 in the Archives of Internal Medicine analyzed the effect of black tea on 95 men and women with normal to high-normal blood pressure levels. Half of the participants drank 3 cups of black tea daily for 6 months, and the other half drank a placebo drink with a similar flavor and caffeine content.
At the end of the study, the black tea–drinking group had an average reduction of 2 to 3 points in their systolic (the top number in a blood pressure reading) level, and about two points in their diastolic (the bottom number) level. Although this doesn’t sound like much, the researchers said it’s enough to reduce the risk of heart disease and stroke by 7 to 10%.
Why it works: It’s believed that black tea’s hypertension benefits may be due to the fact that the beverage improves the function of the endothelial cells that line the interior of blood vessels and affect blood pressure. Other research suggests that flavonoids in black tea can improve the tone of blood vessels, helping them channel blood more efficiently.
4. Get more magnesium.
 
A British analysis of 22 studies, published in February 2012 in the European Journal of Clinical Nutrition, found that taking at least 370 mg of magnesium per day reduced systolic blood pressure by 3-4 points and diastolic pressure by 2-3 points in 1,173 study subjects.
This is key, because research shows many adults don’t get the recommended dietary allowance of at least 320 mg of magnesium for women and 420 mg for men, and that for every 100 mg increase in magnesium intake, the risk of stroke is reduced by about 9 percent.
Why it works: Magnesium helps dilate blood vessels and prevents spasm in your heart muscle and blood vessel walls. It also dissolves blood clots. All of these aid optimal heart and blood vessel function and can help to lower blood pressure.
