Arginine
Arginine- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
This supplement has been used in connection with the following health conditions:
Used for Amount Why Angina2 to 3 grams three times per day 
[2 stars] In one study, taking arginine improved the ability of angina sufferers to exercise. Detailed studies have proven that arginine works by stimulating blood vessel dilation.Congestive Heart Failure5.6 to 15 grams per day with a doctor's supervision [2 stars] The body needs arginine to make nitric oxide, which increases blood flow. This process is impaired in people with CHF. It also has been shown to improve kidney function in people with CHF.Erectile Dysfunction1,670 to 2,800 mg daily [2 stars] Blood vessels need arginine to dilate and form an erection. Supplementing with arginine has been shown to help men with erectile dysfunction in some studies.HIV and AIDS Support and Preservation of Lean Body Mass
(Glutamine, HMB)1.5 grams of HMB, 7 grams of L-glutamine, and 7 grams of L-arginine twice per day [2 stars] The combination of glutamine, arginine, and HMB may prevent loss of lean body mass in people with AIDS-associated wasting.Male Infertility4 grams daily [2 stars] The amino acid arginine is needed to produce sperm. Research shows that several months of L-arginine supplementation increases sperm count, quality, and fertility.Pre- and Post-Surgery Health12.5 to 18.75 grams daily before and after surgery [2 stars] The amino acid arginine has a role in immune function, infection prevention, and tissue repair after injury, including surgery.Sickle Cell Anemia and Pulmonary Hypertension100 mg per 2.2 lbs (1 kg) of body weight, three times per day as L-Arginine [2 stars] People with pulmonary hypertension (a life-threatening complication of sickle cell anemia) who received L-arginine had significant improvement in one study.Athletic Performance and Body Composition and StrengthRefer to label instructions 
[1 star] At very high intakes, the amino acid arginine has increased growth hormone levels, which stimulate muscle growth. Trials combining weight training with arginine and ornithine showed decreases in body fat and increases in total strength and lean body mass.Female Infertility and In Vitro FertilizationRefer to label instructions [1 star] Supplementing with L-arginine has been shown to improve fertility in women with a history of failed attempts at in vitro fertilization.GastritisRefer to label instructions [1 star] The amino acid arginine may both protect the stomach and increase its blood flow.HypertensionRefer to label instructions [1 star] The amino acid arginine is needed by the body to make nitric oxide, a substance that allows blood vessels to dilate, thus reducing blood pressure. Arginine given orally and intravenously has been reported to help reduce blood pressure.Wound HealingRefer to label instructions [1 star] Arginine appears to improve wound healing by increasing protein synthesis.The amino acid arginine has several roles in the body, such as assisting in wound healing, helping remove excess ammonia from the body, stimulating immune function, and promoting secretion of several hormones, including glucagon, insulin, and growth hormone.

Comments about GNC L-Arginine 500:
I can't say enough about this stuff. I've noticed significant gains in muscle mass, longer lasting pumps during and after workouts, improved muscular recovery time, increased vascularity, AND it even boosts sex drive by increasing blood flow. This is probably the best supplement I've gotten from here so far. I'm definitely gonna keep using this. I might get the powder form next time because it comes in a larger quantity and is absorbed quicker and more efficiently in the body.

Comments about GNC L-Arginine 500:
I was taking a pre-workout supplement, but caused high blood pressure. Started taking 2-3 1000 mg capsules 30-45 minutes before workouts. I could feel increase in energy levels and notice pumps were easy and longer. Also, L-arginine is good for the blood vessels.

Comments about GNC L-Arginine 500:
It's best to take this 30 minutes prior to working out and going to sleep. Scientifically, it's less effective when taken with a meal. Absolutely more effective when taken alone with water. I usually take 2 grams per day as a dietary supplement, 5 grams prior to workout as nitric oxide boost, and 10 grams prior to bed rest (at least 8 hours of sleep) to increase muscle mass.
During my workouts I was able to endure longer "pump" times without ever feeling like pulling my muscles, however, this made me much sorer afterwards.
The pills are easy to take, the 500mg L-arginine brand is made with gelatine (the pill), which readily dissolves like jello. You could also snap the pills apart, and put the L-arginine powder in a water bottle; depending on the concentration of L-arginine you add per cup of water, you can use this method as a way to quickly boost muscle tone during your workout when you need to drink the chemical mixed and dissolved already.
This product is best useful for begginers and/or those who don't workout too often (e.g. 2 to 3 days a week).- My Beauty Routine Takes:
