How Do I Pick a Good Nitric Oxide Product?
Now that you are aware of which ones are said to be the best nitric oxide supplements, how do you choose from this list, or even from among other choices in the market? Taking the following factors into consideration can help you make the right choice:
Pre-workout boosters vs nitric oxide supplements: Nitric oxide supplements can be considered a pre-workout booster as they help you workout with more intensity and stamina. So it’s easy to confuse them with general pre-workout boosters that may not even contain any nitric oxide among their ingredients. Pre-workout supplements tend to contain stimulants such as caffeine which are usually not included nitric oxide products. You should be aware of such differences and know what type of supplement you are really looking for.
Brand quality – It’s usually better to buy from an established supplements brand than to experiment with unknown manufacturers. If you are choosing a relatively unknown brand, then do your research on the company, if their manufacturing unit is FDA registered and whether they have product return and money-back policies in case you are not satisfied with their product.
Value – Using a nitric oxide supplement is not a one time purchase as you’ll want to continue using the supplement for a while if you are serious about your workouts. So its important that the product is budget-friendly as well as effective. So along with the ingredients list, pay attention to recommended dosages and the number of servings per package to work out how long a purchase will last and how often you will have to buy them.
The right combination of ingredients: Whats makes a supplement truly effective is the ingredients used in its formula. Check the label to find out what ingredients are used and their quantities. The next section is devoted to the common ingredients used in nitric oxide supplements and how they function, so read on.
5 Ingredients Commonly Used in Nitric Oxide Products
Each brand of nitric oxide supplements boasts of its unique formula that offers you a multitude of health benefits. All the ingredients in a nitric oxide supplement may not directly boost nitric oxide levels directly, some of them are added in the formula to enhance workout performance. Though there are innumerable combinations of ingredients used, the most common ingredients used in nitric oxide supplements are:
- Arginine – L-arginine is one of the most vital ingredients in a nitric oxide supplement since the breakdown of this amino acid releases nitric oxide. Nitric oxide causes blood vessels to open wider for improved blood flow. L-arginine also stimulates the production of hormones such as insulin and HGH (the human growth hormone). HGH plays a key role in metabolism, cell repair, and muscle growth. Though L-arginine is not an essential amino acid and the body can synthesize this on its own, supplementing with L-arginine is evidently beneficial to those who exercise regularly. L-arginine helps improve athletic performance, reduces high blood pressure, and prevents inflammation.
- Citrulline – If your nitric oxide supplement does not contain L-arginine, no worries as long as it contains citrulline. Citrulline is also an amino acid which when taken as a supplement gets converted into L-arginine. In fact, citrulline is said to be a more effective way to use L-arginine than direct supplementation with L-arginine.
- Branched Chain Amino Acids – Branched-chain amino acids (BCAAs) are amino acids that offer a number of key benefits for athletes and bodybuilders. A combination of leucine, isoleucine, and valine, BCAAs increase protein synthesis, leading to enhanced muscle growth. Leucine is a powerful anabolic trigger that is especially effective at boosting strength and stamina during exercise sessions. It also stimulates muscle recovery and growth after the workout.
- Beta-Alanine –The amino acid beta-alanine boosts endurance during workouts by replenishing carnosine stores. Carnosine reduces lactic acid accumulation in your muscles during exercise and helps delay the onset of neuromuscular fatigue which, in turn, leads to more effective exercise sessions and improved athletic performance.
- Creatine – One of the most popular fitness supplements in the industry, creatine is used by your muscles as fuel once they use up their stores of the primary energy source of ATP. Creatine helps to increase strength during high-intensity exercise by up to 15%.
Health Benefits of Nitric Oxide Supplements
Nitric oxide supplements are most sought after for their strengthening and endurance-boosting properties. It offers many other health benefits as well.
- Lowers Blood Pressure
Nitric oxide is a vasodilator. It increases blood flow and lowers blood pressure by relaxing the inner muscles of blood vessels and widening them. The boost in blood circulation also increases the utilization of glucose and the availability of energy.
- Boosts Exercise Performance
The above-mentioned properties of nitric oxide are what make this a popular supplement among athletes and bodybuilders as it helps increase blood flow during and after workouts. This ensures that more nutrients are delivered to your muscles for their recovery and growth.
- Helps Treat Erectile Dysfunction
Nitric oxide helps the penis muscles to relax and the blood flow to the penis increases, allowing the penis to become erect. A 2011 Italian study found that L-citrulline supplementation improved erection hardness in men with mild erectile dysfunction, though it is not as effective as Viagra.
- May Decrease Muscle Soreness
A 2012 study from Rush University Medical Center, Chicago, USA, observed that L-citrulline supplementation increased nitric oxide production, and worked to decrease muscle soreness. Delayed-onset muscle soreness is usually at its strongest 24–72 hours after strenuous or unaccustomed exercise. Of the 41 study participants, those who were given 8 grams of citrulline malate ((instead of a placebo) reported 40% less muscle soreness at 24 and 48 hours after the exercise. The nitric oxide produced by the citrulline supplementation increases nutrient delivery and helps clear waste products such as lactate and ammonia, thus reducing muscle fatigue.
- May Help Manage Type 2 Diabetes
Nitric oxide production is found to be reduced in those suffering from type 2 diabetes. This affects blood circulation and over time leads to more health complications such as high blood pressure, kidney disease, and heart disease. Thus supplementing with nitric oxide may help with diabetes treatment and disease prevention. Studies have found that L-arginine supplementation increased insulin sensitivity and improved blood sugar control in people with type 2 diabetes.
How to Take Nitric Oxide Supplements
Nitric oxide supplements are available as capsules, as well as, in powder form. Though the capsules may seem much more convenient for use, the powdered versions have their own advantages. The capsule forms tend to be purely nitric oxide supplements while powder forms tend to be pre-workout boosters with additional workout enhancing ingredients such as BCaas and creatine. Powder supplements can be mixed into smoothies for a refreshing pre-workout drink.
Nitric oxide supplements are best taken 60 to 90 minutes before a workout session and the efficiency of the product is most enhanced if taken on an empty stomach. But some users have reported stomach discomforts while taking nitric oxide on an empty stomach. For such people, smoothies blended with a powder supplement may help reduce their discomfort. If you are taking a capsule form, then have it with a light snack.
The specific dosage of nitric oxide supplements will depend on the strength of formulation and the ingredients in it, so it’s best to follow the instructions given on the product label, from the manufacturer.
Side Effects of Nitric Oxide Supplements
When taken in recommended dosages, nitric oxide supplements are generally safe for consumption. As mentioned earlier, gastrointestinal discomforts can occur in some users, especially when the supplement is taken on an empty stomach. If you experience such discomforts even after taking the supplement with food, then you can consider lowering your dosage until your body adapts to the supplement.
A 2005 US study, the researchers noted that 5 and 9 grams of arginine led to notable GH response, but a 13 g dose of the same caused considerable gastrointestinal distress in many of their test subjects without augmentation in the GH response. So bear in mind that a higher dose is not necessarily a better choice and keep your dosage under 10gms.
Since nitric oxide is a vasodilator that impacts blood circulation, it may cause changes to your blood pressure. The dilation of the blood vessels may lead to low blood pressure resulting in symptoms like dizziness, headache, nausea, and vomiting. In such circumstances, it’s best to get immediate medical attention and the advice of your physician regarding continuing to use the supplement.
5 Ways to Increase Nitric Oxide Naturally
Even if you are taking nitric oxide supplements, there are many lifestyle factors that influence nitric oxide production in your body. To maintain optimal levels of nitric oxide in your body, incorporate these lifestyle changes to naturally increase your levels of nitric oxide.
- Eat Foods High in Nitrates
Foods with nitrates are a great way to increase your nitric oxide levels as the nitrates are converted into nitric oxide, offering a wide range of benefits. Celery, lettuce, beetroot, spinach, and arugula are some of the vegetables high in nitrates. Beetroot, especially, has been found to improve exercise performance in athletes. There is some concern regarding nitrate content foods causing cancer, but nitrates from vegetables are harmless. It is the nitrates in processed meats that may cause health problems when eaten in excess over long periods.
- Increase Your Intake of Antioxidants
Nitric oxide has to be constantly replenished as it tends to degrade quickly in the bloodstream. Though nitric oxide is an unstable molecule, you can limit this breakdown and increase its stability by consuming more antioxidants in your diet. Antioxidants such as vitamin C, vitamin E, polyphenols and glutathione neutralize free radicals and contribute to increasing the life of nitric oxide.
Many studies have observed that the intake of nitric oxide precursors, such as citrulline or nitrate, in combination with antioxidants, reduce the breakdown of nitric oxide in the body. Vegetables with high nitrate content also tend to have high antioxidant content and thus they are effective in helping maintain optimum levels of nitric oxide.
- L-Arginine/ L-Citrulline supplements
L-Arginine converts to nitric oxide via a process known as the L-arginine-NO pathway. 10 to 20 grams per day of L-Arginine may help reduce blood pressure and increase blood flow in those with high blood pressure, including pregnant women with gestational hypertension.
L-citrulline is produced as a byproduct during the conversion of L-arginine to nitric oxide. It is then recycled back to L-arginine for increasing the production of nitric oxide. Since a major portion of the L-arginine intake may get broken down even before they reach your bloodstream, L-citrulline supplementation may be a better choice. L-citrulline raises L-arginine levels in the blood more than supplementing with L-arginine itself does.
- Limit Your Use of Mouthwash
Nitric oxide is produced from nitrates, in the human body, with the help of beneficial bacteria. Using mouthwash to rinse your mouth kills bad bacteria that cause dental cavities as well as beneficial oral bacteria.
The negative effect of mouthwash on oral bacteria needed to produce nitric oxide can last for about 12 hours. This leads to a fall in the nitric oxide levels in the blood which, in turn, may increase blood pressure. Nitric oxide also regulates insulin, hence without adequate levels of nitric oxide, insulin cannot function properly. A 2017 US study found that those who used mouthwash twice a day were 65% more likely to develop diabetes than people who never used it. So limit your use of mouthwash to raise your nitric oxide levels.
- Get Your Blood Flowing With Exercise
Exercise raises your body’s natural ability to produce nitric oxide. Regular exercise also enhances antioxidant activity which, in turn, inhibits the nitric oxide breakdown caused by free radicals. Studies have found that exercising for 30 minutes, at least three times a week, for a period of 10 weeks, increases your body’s natural ability to produce nitric oxide.
The Final Note
There are many nitric oxide supplements in the market, with a variety of ingredients and formulations. Compare our top 10 nitric oxide products of 2020 to see which one is suitable for your needs. Nitric oxide plays many important roles in the healthy functioning of the human body. It helps relax and widen blood vessels, lowers high blood pressure, and increases the availability of oxygen and nutrients to the cells.
Supplementing with nitric oxide has been found to help improve exercise performance and endurance. It reduces muscle fatigue and speeds up muscle recovery. It also offers a variety of other health benefits such as managing blood pressure and blood glucose.
