Many chemicals, such as chlorogenic acid, caffeine, and triglycerides, make you wonder about the presence of arginine. But is coffee high in arginine?

Though raw Coffee beans contain arginine, the quantity falls to unnoticeable levels when roasted. So coffee isn’t high in arginine, and your cup of coffee can typically contains 44 mg of arginine. The daily dose of arginine should not be more than 9 grams to keep a balanced metabolism in the body. Let’s find out if this protein is beneficial or damaging effects on our bodies.

Is Coffee High In Arginine?

Among 500 amino acids found in nature, 20 are building materials for human body protein. Of those 20 amino acids, arginine is responsible for opening veins to increase blood circulation. Also, it plays a significant role in enhancing immunity.

Raw coffee beans naturally contain some arginine, but their level gets low when roasted beans. There are almost 200 mg of arginine in brewed coffee. Other contents such as cellulose, sucrose, and chlorogenic acid are also present in coffee beans which diminish after 4 minutes of roasting. So, once beans are roasted, your coffee no longer contains arginine.

What Does Arginine do To Your Body?

There are multiple benefits offered by arginine in the human body, such as wound healing, blood vessel dilatation, removing toxic wastes from kidneys, and minimizing blood-related disorders.

What Arginine Do To Your Body

The human body also naturally produces arginine; consuming it through diet can increase its normal levels. Exceeding the optimum levels can cause several side effects, such as decreased blood pressure, diarrhea, bloating, allergies, etc.

Arginine (essential) or L–arginine (non-essential), the relevant amino acid, is functional for repairing the wear and tear in the body while also removing the blockages in blood vessels. There are the following health benefits resulting from arginine:

  • Intaking arginine pally help in the reduction of high blood pressure in hypertensive patients.
  • Sometimes the normal pregnancy gets complicated due to increased blood pressure and compromises the fetus's life. It permanently affects the fetus's brain and body, leading to a high chance of miscarriages which can be resolved by intaking arginine.
  • Other issues, such as peripheral arterial diseases, angina, and erectile dysfunction, are treated with arginine.

Does Caffeine Has Some Impact on L-Arginine?

Coffee containing arginine also includes a large proportion of caffeine that alternatively increases the arginine quantity. More arginine means more nitric oxide production for the body's metabolism. Caffeine is coffee's main content, which helps boost energy and make you feel. More active and focused. It also quickly improves daily moods and directly impacts CNS (central nervous system) to minimize the risk of neurodegenerative disorders such as Dementia and Alzheimer’s.

Does Caffeine Has Some Impact on L-Arginine

You might have heard about the mood-elevating hormone dopamine, which also results after intaking coffee to decrease stress and depression. This significantly defines the positive impacts of coffee and caffeine on your body and brain. But how does coffee affect L-arginine? The answer is simple, coffee increase arginine, and with increased caffeine, the body gets positive outcomes from L-arginine.

How Does Caffeine & Arginine Affect Athletes

After strenuous activities, the athlete's body starts to sweat, which can result in dehydration and decreased blood pressure. With arginine intake, the blood pressure will drop even lower.

In case you take caffeine right before a workout, it will dilate all the blood vessels, while arginine will lower the peripheral resistance to make it easy to allow blood flow. When you start working and exerting force on your body, it increases the demand for oxygen by the body.

Your heart starts pumping blood faster to tissues in need, but as the vessels are already dilated enough, it will get difficult to pump blood and transport oxygen. This is a critical scenario because the stress stimulated by caffeine will also induce a fight and flight response in the body.

The heart rate will increase, surpassing normal limits and increasing the demand for oxygen and nutrients. All impact will be on the lungs, which will try to compensate for the body's demands for oxygen, and these factors collectively cause heart failure.

What Foods Are High In Arginine?

Coffee isn’t the only source to fulfill the need for arginine by the body. Various foods are higher in arginine than coffee, such as beef, turkey, chicken, nuts, and dairy.

You must recognize the importance of arginine in the body to perform different functions, and most of the requirements are met with arginine production inside the body. However, if your body isn’t producing sufficient arginine, you can take such diets for compensation.

The human body needs at least 2 to 3 grams of arginine daily, which can be taken from beef, chicken, and turkey. You can also eat milk, cheese, yogurt, and nuts to get the minerals and vitamins for a healthy lifestyle.

Note: The exceeded amounts of arginine in the body can restrict the production of lysine (amino acid) responsible for treating cold sores. So, avoiding coffee or other foods containing arginine is often advised.


When should you take or avoid L-arginine?

The most recommended time for taking L-arginine is before working out. You must consume it half an hour before you start your regular workout to maximize performance and muscle pump. However, you should never take L-arginine if you have a heart attack, as this will badly impact your heart and cause immediate death in worse scenarios.

How to neutralize L-Arginine in the body?

Among all essential and non-essential amino acids, arginine has the most complicated metabolic path and cannot be neutralized easily. To get rid of it, your body, dietary restriction, enzymatic destruction, and dialysis can greatly help.

How long does the body take to remove L-arginine from the system?

The typical half-life of arginine is between 30 to 120 minutes. However, this mainly depends on the dose and the body condition of the person taking it. If your body has excessive arginine levels, you may feel nausea, bloating, gout, headaches, and severe allergies leading to airway inflammation.

Final Thoughts

So, is coffee high in arginine? Summarizing all the facts, coffee naturally contains lots of good nutrients required by the body, including arginine. Everyone needs this protein for better body growth, but the amount doesn’t exceed in coffee after roasting beans. So, considering your body's need for arginine, coffee isn’t high in arginine.
