How many grams arginine

The nitric oxide causes blood vessels to open, allowing increased blood flow through the body. In addition, MedlinePlus reports that it increases the release in the body of human growth hormone, or HGH, which plays a major role in muscle development. By consuming too much arginine, you may be putting yourself at a higher risk for bleeding. Arginine can be deadly in children when consumed in excess.

The recommended dosage of arginine varies depending on the treatment. For congestive heart failure, MedlinePlus recommends doses ranging from 6 g to 20 g per day, which varies on a case-by-case basis. For relieving chest pain caused by clogged arteries, 9 g to 28 g of arginine is taken in equal increments three or four times daily. Men suffering from erectile dysfunction may benefit from 5 g of L-arginine per day. Volek mentions 6 g per day as an effective dosage for improving physical performance.

Arginine supplementation may cause adverse reactions in some people, such as those with herpes, young children, patients with low blood pressure, or individuals about to have surgery. Your body usually makes all the L-arginine it needs. L-arginine is also found in most protein-rich foods, including fish, red meat, poultry, soy, whole grains, beans and dairy products.

As a supplement, L-arginine can be used orally and topically. It can also be administered intravenously IV. Because L-arginine acts as a vasodilator, opening dilating blood vessels, many people take oral L-arginine to treat heart conditions and erectile dysfunction. L-arginine is considered to be generally safe. It might be effective at lowering blood pressure, reducing the symptoms of angina and PAD , and treating erectile dysfunction due to a physical cause.

L-arginine isn't recommended for people who have had a recent heart attack due to concerns that the supplement might increase the risk of death. L-arginine can worsen allergies or asthma. Use the supplement with caution if you have these conditions. Be careful about taking L-arginine if you've had cold sores or genital herpes. Too much L-arginine in your system can potentially trigger the virus that causes those conditions. There is a problem with information submitted for this request.

Supplementation with the amino acid , L-arginine 16 grams per day , has been shown to improve fertilization rates in women with a previous history of failed attempts at in vitro test tube fertilization.

Various amino acids have shown promise for people with gastritis. In a double-blind trial, taking mg of cysteine four times daily provided significant benefit for people with bleeding gastritis caused by NSAIDs such as aspirin. Cysteine is a sulfur-containing amino acid that stimulates healing of gastritis. In a preliminary trial, 1—4 grams per day of NAC N-acetyl cysteine given to people with atrophic gastritis for four weeks appeared to increase healing.

Glutamine , another amino acid is a main energy source for cells in the stomach and supplementation may increase blood flow to this region.

Patients in surgical intensive care units often develop gastrointestinal problems related to a glutamine deficiency. When burn victims were supplemented with glutamine, they did not develop stress ulcers, even after several operations. Nevertheless, it remains unclear to what extent glutamine supplementation might prevent or help existing gastritis.

Preliminary evidence suggests the amino acid arginine may both protect the stomach and increase its blood flow, but research has yet to investigate the effects of arginine supplementation in people with gastritis. The amino acid arginine is needed by the body to make nitric oxide, a substance that allows blood vessels to dilate, thus leading to reduced blood pressure. Intravenous administration of arginine has reduced blood pressure in humans in some reports.

In one controlled trial, people not responding to conventional medication for their hypertension were found to respond to a combination of conventional medication and oral arginine 2 grams taken three times per day.

Arginine supplementation increases protein synthesis and improves wound healing in animals. Two controlled trials have shown increased tissue synthesis in surgical wounds in people given 17—25 grams of oral arginine per day.

Most people do not need to take extra arginine. While some people with serious infections , burns , or other trauma should take arginine, appropriate amounts must be determined by a doctor. Levels used in research vary considerably 2—30 grams per day.

Most research on cardiovascular disease has used between 6 and 20 grams per day. Optimal intakes remain unknown and are likely to vary depending upon the individual. Dairy, meat and poultry, and fish are good sources of arginine. Nuts and chocolate also contain significant amounts of this amino acid.

Normally, the body makes enough arginine, even when it is lacking in the diet. However, during times of unusual stress including infection , burns , and injury , the body may not be able to keep up with increased requirements. Arginine works with ornithine in the synthesis of growth hormone. For most people, arginine has so far appeared to be free of obvious side effects. However, longer-term studies are needed to confirm its safety.

In a double-blind study, supplementation with 9 grams of arginine per day for six months, beginning within 3 to 21 days after a heart attack , resulted in an increase in the mortality rate.

Arginine is beneficial for other manifestations of heart disease, such as heart failure and angina. However, because of the potential for arginine to cause adverse effects in heart patients, people with heart disease should consult a doctor before taking arginine.

There have been two case reports of severe allergic reactions following intravenous administration of L-arginine; 2 however, allergic reactions have not been reported after oral administration. People with kidney or liver disease should consult their doctor before supplementing with arginine.

Some doctors believe that people with herpes either cold sores or genital herpes should not take arginine supplements, because of the possibility that arginine might stimulate replication of the virus.
