Millions buy L-arginine powder supplements for their proven abilities to enhance immune system efficiency, help to rid the body of harmful chemicals and assist with the secretion of various hormones.
L-arginine is known in the medical field, as well as in the world of athletics, because it is a precursor to nitric oxide, a substance known for its vasodilation properties.
Many surgeons use it to ensure adequate blood flow during surgical procedures when anesthetics may have a slowing effect on heart muscle function.
By increasing the diameters of blood vessels, enhanced blood delivery is accommodated; thus increasing the volume of blood delivered to various cellular structures, like muscles, organs and more.
With more blood delivered, more nutrients and synthesizing hormones are brought along. This often results in a variety of generalized health benefits.



- Boosts nitric oxide production for workouts
- Reduces fatigue & promotes muscle growth
- Supports immune function & sexual health

The L-form of arginine is one of the twenty amino acids that are most commonly found in nature.
L-arginine is a foundational constituent of messenger ribonucleic acid (mRNA), and as such is integral for life.
It is semi essential, not fully essential, because the human body cannot synthesize it during fetal development.
As adults, our bodies do make sufficient amounts of this chemical to meet basic requirements.
However, many bodybuilders, athletes and health-conscious individuals buy L-arginine pills to increase their intake for positive outcomes.
To gain L-arginine from food sources, focus of choices including red meats, fowl, seafood and various dairy products. By eating a diet with adequate protein intake, you can help to ensure L-arginine levels are sufficient.
Who Uses L-arginine?
It is used medicinally for an array of purposes including:
- Treating congestive heart failure and coronary artery disease;
- Decreasing high blood pressure;
- Alleviating chest pains associated with angina;
- Treating intermittent claudication;
- Treating dementia and senility;
- Treating erectile dysfunction and male infertility;
- Strengthening libido;
- Ensuring proper blood flow during anesthetic-based surgical procedures;
- Preventing muscle wasting in post-surgery patients;
There are many other reasons to buy L-arginine powder for supplementation. Continuing clinical research is underway to discern all the possible, and likely benefits associated with L-arginine supplementation.
Why Buy L-arginine Powder Supplements?
Inside the body, L-arginine is converted into nitric oxide (NO2). Nitric oxide is a known vasodilator that works by relaxing the linings of the blood vessels; the endothelium.
When endothelium relaxes, blood vessels are able to expand diametrically. This in turn increases the volume of blood flowing through the vessels.
With increased blood flow, there is a direct increase in the amount of nutrients being delivered intravenously.
As the system of blood vessels and capillaries are affected by vasodilation on a full-body level, the effects can be beneficial for treating a wide variety of symptoms and conditions.
To date, there have not been enough clinical studies to prove, or disprove, many of the potential medical uses of L-arginine powder supplements.
However, there is extensive evidence that it can promote athletic performance, muscle building, healing, sexual function and more.
L-arginine powder or tablet supplementation is considered by many to be effective as an adjunct therapy for symptoms involved with the following:
- Hypertension (high blood pressure);
- Preeclampsia;
- Interstitial cystitis;
- Syndrome X and type ii diabetes mellitus;
- Trauma and burns;
- Kidney malfunctions;
- Digestive tract inflammation;
- Constantly cold hands and feet;
- Common cold;
- More…
Other Uses for L-arginine Powder
L-arginine stimulates the pancreas to release more insulin. When there is more bioavailable insulin in the body, one of the positive effects is that muscle growth and repair capacities are enhanced.
This fact, combined with the generalized vasodilation effects of L-arginine, make it a very popular supplement for bodybuilders, weight lifters and athletes that desire increased muscle mass, strength and endurance.
L-arginine powder is also often stacked with other supplements designed to increase Nitric Oxide levels in the body. You will find various NO Booster supplements sold online and in bodybuilding and health stores.
While these supplements may be safe for the majority of individuals, there can be some side effects when taken by those who have a history of cardiovascular health issues or low blood pressure.
Speak to a doctor before buying an L-arginine supplement or NO Boosting stack. Serious side effects are possible if an overabundance of NO is present in the system for an extended time period.
Not enough clinical evidence yet exists to make any definitive dosing recommendations for specific treatment goals. Follow dosing guidelines provided by the manufacturer for any L-arginine supplement you buy.
Generally, dosages of between 3 – 6 g are taken up to three times a day for muscle building or athletic performance enhancement. This amounts to a total dosage of 9 – 18 g per day.
However, some users report that taking amounts higher than 10 g results in diarrhea and digestive discomfort. You may need to increase your dose slowly over a period of two weeks to adjust to the supplement.
Safety and Side Effects of L-arginine Powder
There are some possible side effects to consider for those thinking of buying L-arginine powder or pills. Those with herpes, cirrhosis, kidney problems, heart issues, allergies and/or asthma should only purchase L-arginine supplements with their doctors explicit permission.
As L-arginine is common in nature, it is generally well tolerated as a supplement for healthy individuals. Possible side effects include gas, bloating, upset stomach, gout, airway constriction and low blood pressure.
Also, never combine L-arginine supplements with antihypertensive medications and/or nitrate-based medications. Finally, do not use L-arginine with sildenafil (viagra) or similar drugs.
