Nitric Oxide and Cardiovascular Health

Millions of peopleNitric Oxide molecule are plagued by high blood pressure from unknown causes (essential hypertension) which is a major risk factor for strokes and heart attacks. High blood pressure also causes kidney damage. But, increasing NO levels appears to be a major way of getting blood pressure back into normal ranges.

The research suggests that increasing NO levels can help prevent, slow or even reverse arterial plaque, thereby helping to keep arteries healthy and flexible. It can also help prevent thrombosis, the formation of blood clots in the circulatory system that cause heart attacks, strokes, and other problems.

Reduced blood flow from a lack of NO is also one of the causes of erectile dysfunction (ED). In fact, many drugs for ED work by increasing NO levels.

Another benefit of NO is that increased levels can improve athletic performance by helping more blood (and oxygen) get to the muscles. Adequate levels of NO will help reduce muscle soreness after exercise.

More Health Benefits of Nitric Oxide

The benefits of NO don’t stop with aiding circulation. Increased NO levels have also been shown to increase cellular sensitivity to insulin, making it helpful for people with diabetes. It also reduces diabetic complications such as blindness, foot and leg ulcers, and kidney disease.

There is also a link between NO and chronic inflammation. While the mechanisms involved in this link are still being explored, it appears that chronic inflammation reduces NO production, whereas enhancing NO production is linked with reduced inflammation. What the research shows is that enhancing NO production may help relieve the chronic inflammation involved in asthma and arthritis.

Finally, it appears that NO plays a critical role in the brain. Low levels are associated with memory loss and depression. There is also evidence that higher levels of NO can improve bone density and aid the immune system in fighting infections.

All of this may be linked to the simple fact that nothing in the body can be healthy or heal without an adequate supply of blood. Anything that interferes with how well the blood can supply oxygen and nutrients to the tissues is ultimately going to lead to health problems.

Endothelial Dysfunction and Low NO

The endothelium or endothelial lining is a layer of cells, just one cell thick, lining the arteries. Because these cells produce nitric oxide to signal the artery muscles to relax and increase blood flow they play a vital role in managing oxygen and nutrient distribution to every other cell of the body.

Endothelial dysfunction occurs when the endothelial lining is damaged. This means that less nitric oxide will be released, resulting in less blood flow to the tissues. This is an underlying factor in chronic and degenerative disease because tissue health cannot be maintained without adequate blood flow.

Chronic inflammation, one of the major underlying factors in chronic and degenerative disease, contributes to low levels of NO and endothelial dysfunction. The more inflammation present in the body, the lower the levels of NO produced by the endothelium. Thus, all the factors that contribute to chronic inflammation are also involved.

Another major factor is mitochondrial dysfunction. Mitochondria are tiny cellular structures involved in energy production and many other body processes. They produce electrical energy or heat depending on the needs of the body. They also produce heme to produce hemoglobin and nitric oxide, both of which help deliver oxygen to the tissues. Mitochondria can also produce free radicals, which can be involved in tissue damage and chronic inflammation.

Understanding all the different ways NO production is linked with inflammation, energy production and overall health is still being explored by researchers. However, we do know a lot about how you can improve your NO production and overall health. What follows are a few simple ways to do so.

Exercising to Enhance NO

Exercising is one of the best ways to enhance NO production. Thirty to sixty minutes a day of walking, swimming, riding a bike, lifting some weights, or engaging in any other form of moderate exercise greatly increases NO levels, which helps reverse endothelial dysfunction and improve blood flow throughout the body.

Exercise helps prevent cardiovascular disease, reduces your risk of stroke, helps low blood pressure, balances blood fats and triglycerides, reduces inflammation, eases leg pain, and helps you lose weight. It doesn’t matter how old you are, as soon as you start a program of regular physical activity you start to see the benefits within a few weeks.

NO Helps You Say Yes to Exercise
If you struggle to exercise, you’re in luck. The relationship between exercise and NO levels is reciprocal. That is to say, not only does exercise enhance NO, NO enhances the ability to exercise. Several studies have shown that increasing blood levels of nitrates, a precursor to NO production, results in greater efficiency in energy production and oxygen utilization in the muscles during exercise. The research was done using beet juice to supply the nitrates, which enhance NO levels.

This means that enhancing NO can help you exercise longer and with less fatigue and get even more dramatic results than those seen with exercise alone. This is particularly important to know if you are overweight, asthmatic, diabetic, already have heart disease or any other condition that makes exercise difficult. By enhancing NO, you can jump-start your exercise program.
