Who Should Buy a Nitric Oxide Supplement

A nitric oxide supplement is an ideal choice for those who work out regularly and want to boost their performance. Researched benefits of nitric oxide supplementation include reduced arterial stiffness, reduced blood pressure, and improved carotid artery blood flow. Nitric oxide supplements are beneficial in this case due to the improved heart function it provides, which in turn helps to enhance tolerance to exercise and oxygen delivery to muscles during exercise.

A nitric oxide supplement can also be helpful to men suffering from mild to moderate erectile dysfunction. Studies have shown that the enhanced blood flow provided by NO supplements can help to reduce ED symptoms.

Finally, women who experience high blood pressure in pregnancy, a potentially dangerous condition known as preeclampsia, may also benefit from taking a nitric oxide supplement. Research has shown that pregnant women who took L-arginine supplements had lower blood pressure readings than pregnant women who did not take the supplement.

Important Features to Consider

Not all nitric oxide supplements are created equal. A nitric oxide supplement should be safe, effective, and easy to take. Here’s what to consider when evaluating the options in search of the best nitric oxide supplement for your needs:

  • Format. Arguably the most important factor when shopping for a nitric oxide supplement is the format. There are powders, tablets, and capsules available, but all help achieve the same end result — enhanced blood flow in the body.
  • Ingredients. Another important consideration when it comes to choosing the best nitric oxide supplement is the ingredients. The two most common nitric oxide supplement ingredients are L-arginine — an amino acid naturally found in red meat, dairy products, poultry, and fish, and L-citrulline — a non-essential amino acid found in meat, nuts, legumes, and watermelon, which the kidneys convert into L-arginine. Beyond that, nitric oxide supplements may include other vitamins and minerals, as well as flavorings.
  • Dosage. There’s no sense choosing a NO supplement that has you popping multiple capsules throughout the day, or mixing several beverages. Find a product that has a dose that is manageable for you to take on a regular basis.
  • Labels. Keep in mind that most over the counter supplements are not regulated by the FDA. This leaves the burden of ensuring safety on the consumer, so carefully check information of all ingredients of a supplement before purchasing. Also, look into the reliability of the manufacturer before buying any supplement. Quality manufacturers should list all ingredients and have access to lab tests and studies that show their products are safe and effective.
  • Price point. Finally, consider how much you are willing to spend on a nitric oxide supplement. Nitric oxide supplements vary in price from $10-$50 or more for a month’s supply. Don’t forget to factor in the number of servings per container when breaking down the overall cost of a NO supplement. If a bottle contains 120 capsules, but you need to take 4 capsules daily, it might not be the better option, even if it’s less expensive than the 60 capsule bottle that only requires one capsule per day.

Frequently Asked Questions

What is a nitric oxide supplement and how does it work?

A nitric oxide supplement typically contains L-arginine — an amino acid naturally found in red meat, dairy products, poultry, and fish, and/or L-citrulline — a non-essential amino acid found in meat, nuts, legumes, and watermelon. The body uses nitric oxide for communication between cells, and it is an essential part of a variety of bodily processes, including controlling blood circulation and regulating the activities of several organs.

Nitric oxide is also involved in workouts, aiding in the release of hormones and adrenaline. It’s believed NO helps with blood flow during and after workouts, as well as increasing the utilization of glucose. By supplementing with nitric oxide, you’re increasing the levels of this gas within the body.

What foods are high in nitric oxide?

Foods that are high in the components of nitric oxide include red meat, dairy products, poultry, fish and shellfish, nuts, legumes, sesame seeds, beets, and watermelon. Adding these foods to your diet on a regular basis can help to naturally boost your levels of nitric oxide.

What are the benefits of nitric oxide supplements?

Researched benefits of nitric oxide supplements include reduced arterial stiffness, reduced blood pressure, and improved carotid artery blood flow. It also helps enhance tolerance to exercise and oxygen delivery to muscles during exercise. The enhanced blood flow provided by NO supplements can also be beneficial to those with mild to moderate erectile dysfunction, as well as reducing high blood pressure in pregnancy.

What are the side effects of nitric oxide supplements?

While many people tolerate nitric oxide supplements without any issues, there are some possible side effects to be aware of. Side effects of nitric oxide supplements include nausea, diarrhea, stomach pain, bloating, heartburn, headache, and heart palpitations. Nitric oxide may also worsen liver function in those with cirrhosis, or cause dangerously low blood pressure levels in those who already have low blood pressure. Taking a NO supplement is also contraindicated in those with kidney disease, herpes, and following a heart attack. Always speak with your doctor before taking any supplement to ensure it will not interfere with an existing condition or any medications you may be taking.
