Who Should Buy Nitric Oxide Supplements
Your body naturally produces nitric oxide, which plays a role in several physiological processes such as blood flow and the regulation and release of hormones such as insulin and natural human growth hormone. Many people take nitric oxide supplements to improve fitness performance and recovery, while others take it for its potential effects on blood pressure and overall cardiovascular health. Some men who take nitric oxide supplements report a reduction in erectile dysfunction.
Many athletes (especially weightlifters, bodybuilders, and people in similar sports) take nitric oxide supplements to help them develop more lean muscle mass and get more benefit from each workout. However, more research is needed to determine the effect of nitric oxide supplementation on muscle growth and exercise performance.
Some small studies have shown additional benefits of nitric oxide supplements. People have used nitric oxide to treat altitude sickness, improve lung function in people who suffer from cystic fibrosis, and improve recovery after major surgery or trauma. Though these benefits are not proven in major scientific studies, many people have reported experiencing these benefits after incorporating nitric oxide supplements into their diets.
Important Features To Consider
There are a few important things to consider when choosing a nitric oxide supplement. Here’s what to consider when selecting a nitric oxide supplement.
- Tablet vs. powder supplement. Nitric oxide supplements typically come in either tablet or powder form. Some people find it easier to add tablets to their regular routine because they don’t need to worry about mixing messy powders with water or finding a powder supplement that tastes good.
- Reliable ingredients. According to the FDA, ” The U.S. Food and Drug Administration (FDA) does not have the authority to review dietary supplement products for safety and effectiveness before they are marketed.” Many nitric oxide supplements are made in GMC-certified facilities and undergo independent quality control to guarantee potency, safety, and the quality of the ingredients. Look for a nitric oxide supplement that undergoes some kind of independent quality control.
- Nitric oxide quantities. Nitric oxide supplements come in a range of strengths. Typically, “extra-strength” nitric oxide supplements include about 1,000 mg of ingredients that your body converts to nitric oxide. Additionally, without taking nitric oxide supplements, people typically consume about 5 grams of L-Arginine per day in their regular diet. Consider how much nitric oxide you need to add to your diet and choose a nitric oxide supplement that delivers that amount.
- Desired benefits. Some nitric oxide supplements are specifically formulated for athletes while others are geared more toward people who want to have a well-balanced diet. While the ingredients might be very similar, they may have different quantities. Choose a nitric oxide supplement that is designed to help you accomplish your specific goals.
Frequently Asked Questions
What are nitric oxide supplements and what are they used for?
The two most common nitric oxide supplements are L-Arginine and L-Citrulline. L-Arginine is an amino acid that naturally exists in red meat, dairy, fish, and poultry L-Citrulline is found in nuts, legumes, meat, and even watermelon. Manufacturers can also produce L-Arginine and L-Citrulline in labs and put them in pills, powders, or creams.
Nitric oxide is a natural vasodilator. It relaxes your blood vessels and helps them expand to increase blood flow and lower blood pressure. Many people take nitric oxide supplements to improve blood flow and boost athletic performance, stimulate muscle healing and recovery after exercise, and improve heart health.
Can taking too much nitric oxide be harmful?
Having too much nitric oxide in your body may cause headaches or migraines. Some studies indicate that having high levels of nitric oxide for an extended time can lead to neurodegenerative diseases like Parkinson’s disease, Alzheimer’s disease, or Huntington disease.
There are many foods that naturally boost your nitric oxide levels, including beets, garlic, leafy greens, nuts, seeds citrus fruits, and even dark chocolates! So, it’s essential to factor in how much nitric oxide you are naturally consuming as you add a nitric oxide supplement to your diet.
Are there side effects to taking nitric oxide supplements?
Most people don’t experience any side effects when they add nitric oxide supplements to their diet. Some people experience mild side effects like heartburn, diarrhea, bloating, headaches, and nausea. A few people may experience heart palpitations.
Though side effects are infrequent and usually mild, nitric oxide can be harmful to people with certain medical conditions. People with cirrhosis (liver scarring) should be very cautious because nitric oxide could negatively impact liver function. Also, anyone who already has low blood pressure should avoid nitric oxide supplements. Also, most doctors strongly discourage taking nitric oxide supplements before undergoing surgery.
How does nitric oxide improve fitness and athletic performance?
Many athletes find that higher nitric oxide levels help increase their overall energy, which allows them to work harder and longer in their workouts. L-Arginine and L-Citrulline also support better blood flow, which carries more oxygen and nutrients to the muscles and helps remove lactic acid that builds up after a workout. Less lactic acid means less fatigue and faster recovery time.
For athletes who are looking for an extra “edge” in the gym, nitric oxide might be the perfect, more natural solution. Bodybuilders especially are turning to nitric oxide to reduce their recovery time between weightlifting sessions, reducing fatigue, boosting endurance, and improving oxygen and nutrient flow to their muscles.
