Low Nitric Acid Symptoms: How It Will Affect Your Health?


Neurotransmission, blood circulation, and the immune system of an individual, nitric acid has a lot to do with all of the physiological functions mentioned and also a lot more. It is usually known as the signaling compound and it is quite essential for your body, even only in trace quantities.

Apart from performing all these physiological functions and responsibilities, it can also significantly help in improving the overall health and well-being of the individual. In this article, we will be discussing everything you need to know about low Nitric Oxide in your body and how it is going to affect your body in a consequential manner. Moreover, we will also be letting you know a lot of practical ways through which you can increase the natural production of Nitric Oxide in your body. 

Nitric Oxide and its Major Functions: An Overview

Nitric Oxide is generally known as a signaling molecule based on the functionalities of the same in the human body. It can be found in a gas form when it comes to its physical state in the human body.

Low Nitric Acid Symptoms

The human body is capable of synthesizing the required amount of nitric oxide all by itself through the amino acids obtained by breaking down the protein consumed through the dietary choices of the individual. L-arginine is the amino acid that is responsible for the synthesis of nitric oxide.

After having a sufficient amount of L-arginine amino acids in the body, a group of enzymes known as Nitric Oxide Synthases (NOS), starts to synthesize nitric oxide required for various physiological functions.

As already mentioned, Nitric Oxide Synthases are a group of enzymes and there are three different types of enzymes in it including; Endothelial Nitric Oxide Synthases (eNOS), Neuronal Nitric Oxide Synthases (nNOS), and also Inducible Nitric Oxide Synthases (iNOS). Even though all three of these enzymes are involved in the process of Nitric Oxide synthesis in the human body, each of them has a different role to play in the process. 

Here you will be able to read and understand some of the major functionalities of Nitric Oxide concerning various physiological activities in the human body. 

Increase the blood circulation 

Nitric Oxide is quite crucial when it comes to healthy blood circulation in the human body. Nitric oxide can help in smoothening the muscles in the blood vessels. The smoothening of the blood vessels can result in the dilation of the vessels. This will eventually result in an increased flow of blood through the vessels. 

Maintain the blood pressure levels in individuals 

This can be regarded as a resultant benefit of the former benefit provided by Nitric Oxide. Thus it can effectively regulate the blood pressure levels of the individual through vasodilation and thus prevent chances of getting infected by lifestyle diseases such as hypertension. 

Strengthens Immunity 

The immunity of the individual can also be significantly improved with sufficient levels of Nitric Oxide in the human body. Nitric Oxide can effectively fight against the pathogens entering the human body using its antiviral and antimicrobial properties. Thus it becomes one of the most effective defensive mechanisms of the body. 

Facilitates neurotransmission 

As already mentioned, Nitric Oxide is known as the signaling compound in the human body. This is because of its vital role in the process of communication between the brain cells and neurons. 

Cell growth

Nitric Oxide is also quite important when it comes to the process of cell growth and cell renewal. It is also necessary in functionalities such as cell differentiation and apoptosis. 

Low Nitric Acid Symptoms: Look For These Signs!

Nitric Oxide deficiency happens when it becomes difficult for your body to produce the right amount of the compound required to meet your various physiological requirements. This deficiency can be caused due to a lot of various reasons.

However, aging, lack of a blanched diet, lack of sufficient body movements, and any severe medications, can be considered some of the major reasons for Nitric Oxide deficiency in the human body.

It is important to have a comprehensive understanding of the reasons behind your Nitric Oxide deficiency so that you help your doctor with the diagnosis and have an early treatment that can be more effective. Some of the major symptoms and signs expressed by your body when you have a Nitric Oxide deficiency have been mentioned below. 

Unexplained fatigue 

If you are feeling tired and exhausted most of the time, and do not feel like getting up and taking up the challenges and chores you have to do daily, and if you are unable to find a proper reason for the same, there are high chances for you to have a Nitric Oxide deficiency. When there is no sufficient amount of Nitric Acid in your body, the blood flow and oxygen supply to your cells can get disrupted, resulting in low energy levels. 

Erectile Dysfunction (ED) in men 

When insufficient NO in the body results in poor vasodilation, erectile dysfunction can happen in men. This can also be quite consequential to the mental well-being of the individual. 


This is also a resultant consequence of improper vasodilatory functions, which should have been facilitated by NO. Increased blood pressure can eventually end up in a lot of other cardiovascular diseases. 

Inactive lifestyle 

Since you would be exhausted most of the time, the motivation to maintain an active lifestyle would also be reduced with a NO deficiency. This is due to the lack of sufficient oxygen supply to the cells. 

Poor immunity levels 

If you have insufficient NO in your body, it can easily lead to poor immunity levels. You can easily get infected with diseases and you may also find it quite difficult to heal your wounds.


Now you know what are the early signs and symptoms expressed by your body when it is lacking the required amount of Nitric Oxide. Since Nitric Oxide is intimately related to the cognitive functions and the overall health of the human brain, it is quite important that you look into the issue of Nitric Oxide deficiency seriously and thus take the necessary treatment or medications so that you will not have the deadliest consequences of this deficiency such as an Alzheimer’s disease or Parkinson’s disease caused due to the overall cognitive decline.
