Isometric Handgrip Training Lowers Blood Pressure In Older Adults
Isometric handgrip exercises have also been shown to have a positive impact on blood pressure in older adults. For a quick demonstration of a simple handgrip exercise method, see the video above. Interestingly, a 2013 systematic review concluded improving your handgrip strength was even more effective for lowering systolic blood pressure than conventional endurance and strength training programs.
Other studies have also confirmed the benefit of both handgrip and leg extension exercises on blood pressure. As noted in one of them:
Isometric resistance training lowers , , and mean arterial pressure. The magnitude of effect is larger than that previously reported in dynamic aerobic or resistance training. Our data suggest that this form of training has the potential to produce significant and clinically meaningful blood pressure reductions and could serve as an adjunctive exercise modality.
New Nitric Oxide Medication To Reduce Intraocular Pressure Takes On Glaucoma From A New Angle
Nitric oxide has become a popular dietary supplementusually in the form of beetroot juicebecause it can help improve blood flow and lower blood pressure. As it turns out, nitric oxide also works as a glaucoma treatment. And no, its not eating beets and green leafy vegetables. This novel eye drop could be the first glaucoma treatment to lower intraocular pressure by using nitric oxide to target the trabecular meshwork.1
Boosting Your Nitric Oxide Level Helps Lower Blood Pressure
Another excellent exercise is the Nitric Oxide Dump, demonstrated in this video. This and other high-intensity exercises help normalize your blood pressure by triggering production of nitric oxide in your body. It involves just four movements squats, alternating arm raises, non-jumping jacks and shoulder presses which are done in repetitions of 10, with four sets each. In total, it takes just three to four minutes. Ideally, youd do these exercises three times a day, a few hours apart.
Nitric oxide is a soluble gas stored in your endothelium and acts as an important signalling molecule throughout your body. Along with promoting healthy endothelial function, nitric oxide also supports heart health by helping your veins and arteries dilate, which promotes healthy blood flow.
Nitric oxide also plays a protective role in your mitochondrial health, the energy storehouse of your cells, responsible for the utilization of energy for all metabolic functions. Even your skeletal muscle, which is made up of only about 1 percent to 2 percent mitochondria, depend on these energy powerhouses to fuel your daily movements.
When you exercise and your muscles ache, its because youve run out of oxygen, which your body compensates for by releasing nitric oxide. But heres the secret thats not widely known: When you exercise, it takes only about 90 seconds for your blood vessels to run out of stored nitric oxide and begin the process of making more.

Nitrate Sources And Placebos
As mentioned previously, various distinct sources have been tested in clinical studies investigating the effects of nitrate on blood pressure, including nitrate capsules and various forms of food supplementation, from spinach to beetroot juice and even nitrate enriched bread products .
In recent years however, beetroot juice has been particularly popular as a convenient way to deliver a controlled dose of inorganic nitrate, both using concentrated shots and traditional beetroot juice drinks. However, it is worth noting that a recent study by Jajja et al. showed it is important for investigators to quantitatively assess the concentration of nitrate in their beetroot juices to confirm levels reported by the commercial supplier. For example, in this paper, the supplier reported a nitrate dose of 300400 mg per bottle, but Jajja et al. found a concentration of only 165 mg per bottle. Such variations may underlie some of the differences in outcome reported in the literature.

What Foods Activate Nitric Oxide
Some foods contain antioxidants, especially polyphenols, which stimulate nitric oxide production and increase its bioavailability. Following a Mediterranean style diet, or a DASH diet, naturally boost the bioavailability of nitric oxide, and the list of foods with the greatest beneficial effects reads like a dream menu fruits, vegetables, dark chocolate, nuts, olive oil, black and green tea as well as red wine.
These foods all help to dilate arteries and lower blood pressure through effects on nitric oxide especially pomegranate juice, globe artichoke, apples, cacao, blackberries, blueberries, strawberries, black grapes, red peppers, black beans, kidney beans, soy beans, red onions, cherries, tomatoes, garlic and pumpkin seeds.
Some milk peptides found in dairy products, such as lactoferrin, appear to increase the activity of genes encoding proteins involved in nitric oxide, and some whey proteins have been found to improve blood flow through coronary arteries.
The antioxidant effect of vitamin E on blood vessel linings is believed to increase the release of nitric oxide, which has a powerful ability to dilate blood vessels and lower blood pressure. Vitamin E is found in vegetable oils , avocado, wholegrain cereals, nuts and seeds.
May Help Manage Type 2 Diabetes
Nitric oxide production is impaired in people with type 2 diabetes .
This leads to poor blood vessel health, which can lead to conditions like high blood pressure, kidney disease and heart disease over time.
Therefore, supplements that increase nitric oxide may have important implications for diabetes treatment and disease prevention.
One study found that when people with type 2 diabetes took L-arginine, their nitric oxide production increased .
This increase in nitric oxide also led to increased insulin sensitivity, allowing for better blood sugar control.
Another study in 144 people looked at the effects of L-arginine on preventing or delaying the progression of type 2 diabetes .
While L-arginine did not prevent people from developing diabetes, it did increase insulin sensitivity and improve blood sugar control.
But until more research is available, it is premature to recommend taking L-arginine supplements to treat diabetes.
Summary People with diabetes have impaired nitric oxide production, which can lead to harmful health effects. L-arginine has been shown to improve blood sugar control in people with diabetes, but more research is needed before it can be recommended.

The Effects Of A Traditional Japanese Diet On Blood Pressure
There are a number of observations that support the proposals made by The NIH Workshop attendees. The traditional Japanese diet, which is typically high in inorganic nitrate from vegetables such as ta cai, Chinese cabbage and spinach , has been associated with lower systolic and diastolic blood pressures. On the contrary, a westernized diet in the same Japanese population was associated with higher blood pressure . The effects of a traditional Japanese diet compared to a control diet have been investigated in a clinical study expanding on this finding. The traditional Japanese diet resulted in an average decrease in mean diastolic blood pressure of 4.5 mmHg , but had no significant effect on systolic blood pressure .
Importantly, in this study they demonstrated that the traditional Japanese diet significantly increased plasma and salivary nitrate compared to a control diet, from 43 to 154 M and 200 to 570 M , respectively. Crucially, plasma nitrite was also increased from 132 to 204 nM , suggesting commensal bacteria successfully converted nitrate to nitrite via the enterosalivary circuit. Such observations perhaps provide clues to the apparent longevity and reduced cardiovascular risk in those maintaining a traditional Japanese diet .
How Is Nitric Oxide Stored In The Human Body
Nitric oxide does not usually exist in its free form in the body due to its unstable nature but reacts with other molecules to form more stable products.
- In the blood, nitric oxide has a very short half-life and rapidly oxidises to nitrite. It is then further oxidised with oxyhaemoglobin to produce nitrate. Nitric oxide also reacts directly with oxyhaemoglobin to produce methhaemoglobin and nitrate.
- Reactions with cysteine residues in proteins lead to formation of nitrosylated products. Because of its high affinity to sulfhydryl groups , S-nitrosothiols are the most common nitrosylated product in plasma.
Nitrate is the main storage form of nitric oxide. It is very stable when compared with other storage forms such as nitrites and RSNOs, which are important carriers and donor molecules of nitric oxide.

How Does The Skin Produce Nitric Oxide
As all 3 isoforms of NOS are present either in theepidermal cells, dermal cells or both, skin can produce nitric oxide by an enzyme dependent mechanism.
Human skin can release nitric oxide in an enzyme independent manner by UVA photolysis of nitric oxide stores.
Nitric oxide is also produced by reduction of sweat nitrate by skin commensal bacteria, in particular Staphylococci.
Nitric Oxide Is Involved In A Variety Of Systems And Processes In The Body Such As:
- Impacting memory and behavior, via nerve cells in the brain
- Enhancing immunity by protecting against bacteria and cancer cells
- Enhancing gastric motility
- Insulin signaling
- Proper erectile functioning for men
Nitric oxide is not to be confused with the nitrate free sticker on your deli meats. Nitrates and nitrites get a bad rap because of a certain form thats added to preserve processed meats like bacon and hot dogs, which, during cooking, can form harmful compounds called nitrosamines that are known to cause cancer. This compound is also commonly confused with the nitrous oxide gas used at the dentist office for anxietythese things arent related whatsoever!
Nitrates are naturally found in plants, taken up through the soil and used as the primary source of nitrogen for plants, essential for their growth. They tend to be higher in vegetables than fruits and particularly rich in beets, celery, and leafy greens like arugula and swiss chard. It is a molecule produced by the endothelial cells lining the arteries and acts as a biological messenger involved in a variety of cellular activities.

Nurturing Nitric Oxide: The Heart
Spring break is ending for many Americans, which means jumping back into work and school routines and generally making up the time lost to vacation.
But theres one way to draw out the benefits of downtime: take some long, deep breaths through your nose. Unlike breathing through your mouth, nose breathing helps release nitric oxide, a chemical that expands your blood vessels, lowers blood pressure and has an all-over calming effect. No wonder this technique is central to yoga, meditation and many other stress-relieving practices. While helping you to calm your mind, this tactic can help to achieve the clarity you need to retrench and regain control of the tasks at handand encourage heart health too!
Nitric oxide is vital for a healthy cardiovascular system, but deep breathing is just a start. Produced by the endotheliumthe lining of the blood vesselsthis chemical is highly responsive to healthy heart habits like regular exercise and low cholesterol. Lowering cholesterol levels helps increase nitric oxide. These lifestyle measures turn the nitric oxide spigots on, expanding blood vessels and increasing blood flow while curbing the build-up of plaque.
The keys to raising nitric oxide and lowering ADMA and SDMA are the same:
Ok But Do Nitric Oxide Supplements Actually Work
Honestly, we don’t really know. There’s simply not enough evidence to suggest that they do.
” will increase NO, and then because of that, it’ll cause vasodilation, and then the downstream effect of vasodilation would be this massive increase in blood flow, which leads to increased exercise performance and enhanced recovery,” says Richard Bloomer, Ph.D., dean of the School of Health Studies and The Center for Wellness and Fitness at the University of Memphis. “But most, if not all, of have not been supported by available evidence.”
In studies that have shown a link between improvements in performance and nitrate levels in the blood, such positive results could simply be a result of extensive training, as exercise itself enhances nitric oxide activity. Plus, dietary nitrate comes from other sources, like vegetables, and most studies don’t control for this.
Even if there are benefits to nitric oxide supplementation, it’s unclear whether they would apply to everyone. A review of 42 studies related to the effects of dietary ingredients linked with nitric oxide and exercise performance found mixed results: the review concluded that while nitric oxide supplements may “improve tolerance” to aerobic and anaerobic exercise in people who either aren’t in shape or are moderately trained, there seems to be no benefit in highly trained people.

How To Increase Nitric Oxide Naturally
There are a number of ways that you can increase nitric oxide levels naturally. These include:
- Eating foods that are rich in nitrates. Well provide a more detailed list of foods that you can eat to increase nitric oxide levels below.
- Consume more antioxidants. This can be done by taking antioxidant supplements, but also by simply eating a healthier diet. Again, read the list of foods high in nitric oxide below.
- Take supplements that can boost NO levels.
- Exercise more. Frequent exercise helps encourage your body to produce higher levels of nitric oxide.
Exercise Is Another Potent Therapy For High Blood Pressure
Inactivity and blood pressure are also closely related so closely that exercise is actually considered a first line of treatment by several health authorities, including the World Health Organization, the International Society of Hypertension and the U.S. Joint National Committee on Detection, Evaluation and Treatment of High Blood Pressure, just to name a few .
Research shows inactive individuals have a 30 to 50 percent greater risk for high blood pressure than their active counterparts . As noted in a literature review on exercise and hypertension, published in Australian Family Physician:
An evidence based literature analysis by the American College of Sports Medicine indicates that an isolated exercise session lowers BP an average of 5 to 7 mmHg The average BP reduction with regular endurance exercise for hypertensives not normalised by drug therapy in the literature review is 7.4/5.8mmHg
Depending upon the degree the patient’s BP has been normalized by drug therapy, regular aerobic exercise significantly reduces BP the equivalent of 1 class of antihypertensive medication Overall, resistance training has a favourable chronic effect on resting BP, but the magnitude of the BP reductions are less than those reported for an aerobic based exercise program

What Is Nitric Oxide
Nitric oxide is a gas that acts as a signalling molecule, or messenger, within the body. Its also referred to as an endothelium-derived relaxing factor due to its role in dilating blood vessels, lowering blood pressure and increasing blood flow.
While nitric oxide is mainly found within blood vessel linings, its also present in the kidneys, platelet cells, heart muscle cells and in some brain and peripheral nerve cells.
What Foods Have Nitric Oxide
As nitric oxide is a gas, it quickly evaporates so is not present in food in significant amounts. However, some foods, such as beetroot, contain nitrates which are converted into nitrites by bacteria that live in your mouth, mainly on your tongue. When you swallow these food-derived nitrites, they are rapidly absorbed into your circulation and are converted into nitric oxide . When eating beetroot or drinking beetroot juice, hold it in your mouth for as long as possible to maximise nitrite production.
You can also increase nitric oxide production by increasing your intake of foods that supply the amino acid, l-arginine, the main building block for making nitric oxide. Vitamin B3 is also needed for this reaction.

Why Nitric Oxide Matters For Heart Health
Arterial elasticity supports normal vasodilation, which improves the blood flow to all organs. Nitric oxide production supports healthy blood pressure levels already within a normal range and blood vessel elasticity.**
The amount of nitric oxide in the body begins to decrease as we get older. Therefore, it becomes necessary to boost its production.
So how can you increase and sustain nitric oxide in your system?

Today, with antibiotics readily abundant and fewer wild tigers on the loose, unchecked inflammation is left to cause many degenerative diseases including atherosclerosis, Alzheimers, and arthritis.
The only difference between inflammation of the regular sort and the kind that triggers atherosclerosis is that high cholesterol, high blood pressure, smoking, and obesity are initiating the inflammation, not infection or trauma. Unlike a brief infection or trauma, these risk factors are longstanding and therefore lead to chronic inflammation and plaque. Active plaques begin to resemble small abscesses on the inside of arteries. These active plaques are thought to be sites of future heart attacks.
