What the research says about L-arginine
Peer-reviewed studies and reviews on the amino acid L-arginine - shared for education, not as claims about this finished product. AOR Arginine's claims are the statements authorized under its Natural Health Product licence, NPN 80002697.
Arginine, the NO substrate
A review explains that L-arginine is the body's essential dietary substrate for synthesizing nitric oxide (NO), a signaling molecule that helps widen blood vessels and increase blood flow to tissues including skeletal muscle.
ReviewHow the body makes nitric oxide
This review describes the nitric oxide synthase enzymes that catalyze the conversion of L-arginine into nitric oxide and L-citrulline, the core biochemical pathway behind arginine's vascular role.
ReviewA Nobel Prize-winning discovery
A historical review traces the 1998 Nobel Prize in Physiology or Medicine, awarded to Furchgott, Ignarro and Murad for discovering nitric oxide's role as a signaling molecule in the cardiovascular system - the same pathway for which L-arginine is the precursor.
Historical reviewArginine and vessel-lining function
A meta-analysis of randomized trials found that oral L-arginine supplementation increased fasting flow-mediated dilation (a measure of endothelial function), with the largest improvements seen in people whose baseline vascular function was low.
Meta-analysisNitric oxide synthase and vascular tone
A review in a leading cardiology journal describes how the nitric oxide synthase enzymes rely on L-arginine as their substrate to regulate the tone of blood vessels throughout the body.
ReviewTesting endothelial reactivity with arginine
A review discusses how L-arginine-based reactivity testing has been used by researchers to help characterize endothelial (vessel-lining) function, including in the cerebral circulation.
ReviewMeta-analysis: arginine and blood pressure
A meta-analysis of 11 randomized, placebo-controlled trials found that oral L-arginine supplementation (4-24 g per day) significantly lowered both systolic (-5.4 mmHg) and diastolic (-2.7 mmHg) blood pressure compared with placebo.
Meta-analysisAn updated dose-response analysis
A 2022 systematic review and dose-response meta-analysis of 22 randomized trials confirmed reductions in systolic and diastolic blood pressure with oral L-arginine, identifying an effective dose of about 4 g per day or more for systolic blood pressure.
Meta-analysisThe arginine-nitric oxide pathway in hypertension
A review describes how a reduced or impaired L-arginine-to-nitric-oxide pathway is implicated in the pathophysiology of difficult-to-control high blood pressure.
ReviewFood-based NO-pathway nutrients and endurance
A systematic review and meta-analysis examined whether dietary sources of nitrate, polyphenols, L-arginine and L-citrulline (compounds that support nitric oxide availability) can enhance endurance exercise performance.
Meta-analysisSingle-dose arginine and blood flow
A randomized crossover trial gave physically active men either L-arginine or a placebo before resistance exercise; the increase in blood flow and vascular response seen after exercise was attributed to the exercise itself rather than to the added arginine.
Human RCTRaising plasma arginine around training
A week of arginine-alpha-ketoglutarate supplementation raised plasma L-arginine and nitric-oxide-metabolite levels around resistance exercise, though the study attributed the blood-flow response itself mainly to the exercise bout.
Human RCTMeta-analysis on amino acids and wound repair
A systematic review and meta-analysis evaluated the effect of arginine and glutamine supplementation on wound-healing outcomes across clinical studies.
Meta-analysisHow arginine supports tissue repair
A review describes arginine's roles in protein synthesis, nitric-oxide-mediated cell signaling, and its conversion to polyamines that support cell proliferation - mechanisms relevant to wound healing.
ReviewArginine and glutamine for pressure ulcers
A systematic review examined enteral arginine and glutamine supplementation for supporting collagen synthesis and tissue repair in the management of pressure ulcers.
Systematic reviewA foundational review on arginine and immunity
An early review outlined arginine's role in supporting immune-cell function, part of the foundational research linking this amino acid to the body's immune defenses.
ReviewA regulatory node for immune responses
A review describes how, over the course of immune-system evolution, arginine availability has become a key node regulating the activity of immune cells.
ReviewArginine and post-surgical immune markers
A meta-analysis of clinical trials examined arginine supplementation in relation to immune-function markers and postoperative recovery in surgical patients.
Meta-analysisThe classic arginine infusion test
A landmark clinical study established the arginine-infusion test as a way to stimulate and measure growth-hormone secretion, a tool still referenced in endocrine research today.
Human RCTConfirming arginine's effect on growth hormone
Another early clinical study documented the rise in circulating growth hormone following intravenous arginine infusion, helping establish this amino acid's role in growth-hormone physiology.
Human studyArginine stimulation testing today
A modern study analyzed growth-hormone responses during arginine (plus clonidine) stimulation testing in children being evaluated for short stature, correlating results with metabolic parameters.
Clinical studyReviewing arginine's safety in adults
A review of the safety and effectiveness literature identified an observed safe level of oral arginine intake around 20 g per day in adults, with higher doses tested short-term without serious adverse effects.
ReviewPharmacokinetics across species
Preclinical studies in pigs, rats and sheep examined the pharmacokinetics and safety of oral and intravenous arginine supplementation, informing the dosing science behind later human research.
Animal studyWhy medical supervision matters after a heart attack
A meta-analysis of trials in patients with a recent acute myocardial infarction found that oral L-arginine supplementation did not significantly change clinical outcomes in that setting - part of why cardiac patients are directed to use arginine only under medical supervision.
