![]() ![]() Management of critical illnessĪrginine becomes essential when your body is compromised due to conditions like infection and trauma, and your arginine needs significantly increase due to physiologic demands. L-arginine is needed for the production of nitric oxide, which is necessary for the relaxation of the cells that make up blood vessels, as well as blood pressure regulation.Ī 2016 review of 7 studies found that supplementing with L-arginine by both oral and intravenous (IV) administration significantly reduced systolic and diastolic blood pressure in adults with high blood pressure by up to 5.4 mm/Hg and 3.1 mm/Hg, respectively ( 1). Studies have shown that taking L-arginine supplements may help lower both your systolic (the top number) and diastolic (the bottom number) blood pressure readings. L-arginine supplements may benefit those with high blood pressure. L-citrulline, a precursor to L-arginine that’s discussed later in this article, may be a better choice for boosting athletic performance. However, most studies investigating this relationship have found that L-arginine is not beneficial for improving athletic performance ( 8, 9, 10, 11). Limited evidence suggests that L-arginine supplements may enhance exercise performance by increasing nitric oxide in the body, which improves blood flow and oxygenation to muscles.įor example, a 2017 randomized study in 56 male soccer players found that treatment with 2 grams of L-arginine daily for 45 days significantly increased sport performance, compared with a placebo group ( 6).Īnother small study in 9 men demonstrated that those who drank a beverage containing 6 grams of L-arginine 1 hour before intense exercise had significantly increased blood levels of nitric oxide and were able to exercise longer, compared with a placebo group ( 7). However, results are mixed, and L-arginine may not be as effective for some conditions as many supplement companies claim. Research has shown that L-arginine may offer a variety of potential benefits when used as a supplement. They’re also used in the clinical setting to treat critically ill people or those with wounds. L-arginine supplements are taken by many populations, including athletes and those who have certain medical conditions like high blood pressure, for a variety of reasons. This article mainly focuses on the benefits and uses of L-arginine supplements. L-arginine supplements are widely available and can be found in powder, liquid, capsule, and tablet form at grocery stores, supplement stores, and online. The average daily intake of L-arginine from foods is reported to be 4–6 grams ( 4).įor reference, research shows that a typical Western diet provides between 25–30% of total arginine present in the body ( 5).Īdditionally, L-arginine can be obtained by taking supplements. It’s concentrated in certain protein-rich foods, including meat, poultry, dairy, nuts, soy products, and fish. It can be synthesized from the amino acid citrulline through the breakdown of body proteins, or it can be obtained through dietary protein intake ( 2). It’s necessary for the production of nitric oxide, a signaling molecule that’s needed for a variety of bodily processes and functions, including blood flow regulation, mitochondrial function, and cellular communication ( 1, 3).Īdditionally, it acts as a precursor to other amino acids, including glutamate, proline, and creatine, and is essential for the health and functioning of your immune system.Īrginine is necessary for the development of T-cells, which are white blood cells that play central roles in immune response ( 2).īecause L-arginine has so many critical roles in your body, a deficiency in this amino acid can disrupt cellular and organ function and lead to serious adverse health outcomes ( 2). L-arginine is considered semi-essential or conditionally essential, meaning that it becomes essential under certain circumstances and conditions, including pregnancy, infancy, critical illness, and trauma ( 2). ![]() As such, they must be provided through dietary intake ( 1). Nonessential amino acids are made in the body, but essential amino acids are not. Amino acids are the building blocks of proteins and divided into essential and nonessential categories.
