A healthy heart is key when it comes to working out and being in shape. Being sure to take care of and maintain your heart if working out regularly is a must.

Nutricost’s Nitric Oxide Booster capsules are a great place to start if you are looking around for a solid supplement to obtain in order to create a heart of steel.

What is Nitric Oxide and What Does it Do?

Let’s take a look at why nitric oxide is and how it helps the body.

Improves Overall Heart Health

Citrulline malate, derived from L-citrulline, is recognized for its potential in reducing muscle soreness by enhancing nitric oxide production. This facilitates improved blood flow, aiding in oxygen and nutrient delivery to muscles during exercise (getting a pump). The effectiveness of citrulline malate depends on factors such as dosage and exercise type. Higher doses may lead to more significant effects, particularly beneficial for activities involving intense and prolonged muscle contractions. Individual responses vary, and consultation with a healthcare professional is advised for personalized guidance on dosage and suitability. In summary, citrulline malate holds promise for reducing muscle soreness, contingent on individual factors and proper dosage considerations.

Lowers Blood Pressure

High blood pressure, characterized by consistently elevated levels, is associated with impaired nitric oxide use in the body. Defined as systolic pressure above 130 mmHg and/or diastolic pressure over 80 mmHg, it can lead to heart and kidney diseases. Nitrate converts to nitric oxide, relaxing blood vessels. Studies suggest nitrate supplements and beetroot juice can significantly lower blood pressure. Flavonoids, found in most fruits and vegetables, may also play a role by increasing nitric oxide production and reducing its breakdown, potentially lowering high blood pressure risk. 

Improves Respiratory Response

Taking supplements allow nitric oxide to influence the widening of blood vessels in the lungs. Notably, the administration of this through inhalation has been demonstrated to have acute positive effects on hypoxemia associated with pulmonary hypertension in both human subjects and animals. This suggests that nitric oxide, by impacting key physiological pathways, can offer potential therapeutic benefits in managing conditions characterized by impaired pulmonary blood flow and oxygenation.

Decreases Muscle Soreness

Muscle soreness, often felt after intense or unfamiliar workouts, is known as delayed-onset muscle soreness and peaks 24–72 hours post-exercise. Citrulline malate boosts nitric oxide production, enhancing blood flow to working muscles. This is believed to improve nutrient delivery and remove fatigue-related waste products like lactate and ammonia.

What are Nitric Oxide Booster Supplements?

Blood vessels in the body function due to the presence of nitric oxide, which is a naturally occurring gas inside the body that combines nitrogen and oxygen to help widen blood vessels by relaxing them. No supplements actually contain nitric oxide, but instead aid in the production of it in order to improve vascular health and muscle performance. It also contributes to hormone release simulation and the regulation of neurotransmission between the neurons and muscle fibers throughout the body. The boosters will essentially allow for more of it to be produced, leading to improvement of overall heart, muscle, and brain health. When it comes to working out, it is important for your muscles to be able to rest in order to grow muscle mass between workout sessions. Nitric Oxide boosters allow for faster healing and a decrease in muscle soreness because of the newly made oxygen being delivered to the muscles from blood vessels by the supplement.

Top 3 Benefits of Nitric Oxide Boosters

Let’s take a look at the top 3 reasons to use a supplement of this nature.

Benefit Reason
Increased Pumps Muscle pumps are largely a result of increased blood flow to the muscle tissue. While this will come naturally to a degree when exercise is performed, the blood flow to the tissues with nitric oxide boosters can give you a fuller, longer lasting pump.
Reduced Fatigue When working out, fatigue is a limiting factor in your workout, this is because your body is running out of oxygen, and your lactic acid starts to build up and a nitric oxide booster can help. This boosts the amount of blood and oxygen going to the muscles, reducing your fatigue.
Increased Energy Availability Nitric oxide boosts blood flow and enables you to better maintain your core temperature balance. This may not sound like much, but when body temperature rises significantly during a hard workout session, the body will try its best to cool the tissues. This is so that overheating doesn’t occur, and when you have good blood flow this process is made easier, so less energy will be directed to cooling you down and more is available to you to workout and function.
