L-Arginine For High Blood Pressure


L-arginine is one of the most effective natural remedies for high blood pressure. L-arginine is an amino acid that can be made in the body but is often in short supply, especially in people who are stressed. L-arginine is one of the most effective natural remedies for high blood pressure. L-arginine is used to make a molecule called nitric oxide which increases blood vessel elasticity and dilation to lower a high blood pressure. This action is similar to that of beet juice.




L-arginine for high blood pressure

L-arginine is so effective at lowering blood pressure, that one prescribed blood pressure medicine even uses arginine within its formulation (the ACE inhibitor, perindopril arginine).

In people with borderline high blood pressure, taking l-arginine can lower blood pressure by as much as 11/4.9 mmHg, alongside a 23% improvement in arterial elasticity.

When the data from 11 clinical trials involving 387 people with high blood pressure were polled, the overall result was that l-arginine significantly lowered blood pressure by 5.39/2.66 mmHg more than placebo. The doses used in these studies ranged from 4g to 24g per day.

L-arginine normalises blood pressure without causing it to go too low. When healthy people with normal blood pressure took L-arginine (at doses of 6g to 12g per day for 4 weeks) their blood pressure did not significantly reduce, and most reductions occurred at night.




L-arginine for heart health

L-arginine is also used to lower cholesterol levels and improve elasticity of artery walls in people with coronary heart disease. In one study, people with angina heart pain who took L-arginine three times a day were able to increase their level of exercise without having to stop because of chest pain.

L-arginine for heart failure

Congestive heart failure is a recognised complication of long-term untreated high blood pressure. Taking L-arginine can improve congestive heart failure by improving the elasticity of artery walls and lowering blood pressure. This reduces the resistance against which the heart has to pump, and reduces its work load as it moves blood through the circulation. In people with heart failure, l-arginine can prolong exercise duration and increasing the distance that can be walked.




L-arginine for men

Erectile difficulties can occur as a complication of high blood pressure if there is an underlying furring up of the arteries. Because l-arginine dilates arteries and improves blood flow, it is one of the most popular prosexual supplements for men. L-arginine is used to erectile function and is especially helpful if you also have high blood pressure. In a study involving 50 men with erectile dysfunction, 31% of those taking l-arginine reported a significant improvement in sexual function.

L-arginine dose

L-arginine is found in protein-rich foods such as nuts, seeds, egg yolk, red meat and pulses, and in foods that are rich in nitrates, such as beet root and beet juice.

For supplements, a typical dose is 2g to 3g l-arginine up to three times daily.

It can take between two and six weeks for L-arginine to achieve its optimum effect.

 L-arginine is often combined with another amino acid, l-citrulline, from which l-arginine is made in the body.




L-arginine safety

An Observed Safe Level risk assessment that used published clinical trial data confirmed an absence of adverse effects for l-arginine at intakes of up to 20g per day in normal healthy adults.

Doses above 20 g daily are not recommended except under medical supervision.

Although side effects are uncommon, high doses can cause diarrhoea.

A reversible coarsening of the skin has been reported with long-term use.
