Best L-Arginine Supplement Brand

Arginine is an amino acid which plays a number of vital roles throughout the human body, especially in the area of bodybuilding and athleticism.

Arginine is known for the dilation of blood vessels and enhancement of circulation. So, if you are looking for a pump-enhancing supplement to increase your vascularity and give you an extra edge in the gym, then adding Arginine to your diet could definitely help.

Arginine supplementation increases nitric oxide production, which in turns, provides cardiovascular support to improve blood flow, oxygen delivery, nutrient transportation, and waste removal from the body.

Consumption of L-Arginine can significantly enhance circulation and vascularity, helping to deliver key benefits that extend to athletic performance, sexual wellness, heart health, and cognitive function.

With all the possible health benefits associated with L-arginine, finding the best supplement that works for your purposes will be a matter of understanding the amino acid’s function in the body and current scientific evidence about its efficiency.

Best L-Arginine Supplement

Many advocates of supplement usage will always encourage consumers to choose quality products. However, differentiating between a high or low-quality supplement can be difficult.

The USP, US Pharmacopeial Convention, is a scientific not-for-profit organization that establishes standards for medicines, food products, and supplements, and can serve as a resource for consumers.

Supplement manufacturers can willingly submit their product to the USP, which will ensure that ingredients such as vitamins, minerals, amino acids, botanical extracts, non-botanicals, etc…, are of good quality.

Any L-Arginine supplement that meets the organization’s criteria will carry a USP stamp. This indicates that the product quality is consistent and that ingredients have met standards for strength and purity.

A USP label or stamp also ensures that ingredients are prepared in accordance with manufacturing regulations.

Quality and ingredients will depend on the brand as well as country of origin, and here in the United States, products that have met auditing criteria and stringent testing are labeled dietary supplement USP verified.

Some L-Arginine Products

To mention but a few, below are some L-arginine products that you can check out:

Cellucor NO3 Chrome

Cellucor NO3 Chrome is one of the best arginine supplement because it goes several steps further than the competition with the use of Arginine Nitrate and its patented Extreme Vascularity Complex.

L-Arginine may be beneficial to health and wellness, but there are times when interactions can occur with other medications.

The National Institutes of Health do not recommend taking L-arginine supplements if one is already taking any antihypertensive drugs. This may lead to extremely low blood pressure.

Some of the common antihypertensive medications include Capoten, Diovan, and Cardizem.

Further, it is recommended that you avoid the use of L-arginine when taking anti-diabetes medications, including Amaryl, Glucotrol, Avandia, and others.

L-arginine supplements should not be taken in conjunction with ACE inhibitors for high blood pressure.

Neither should it be taken with angiotensin receptor blockers (ARBs) for high blood pressure, or anticoagulant forming drugs including Plavix, aspirin, Coumadin, and others.


It is extremely important to speak with your doctor or health experts before starting any supplement program.

This is to avoid any possible drug interactions and to make sure the product is right for you.
