Buying a good L-Arginine supplement can be a daunting task. With so many brands, forms, and choices, it’s hard to know which one is right for you.

On top of that, there are lots of other questions to consider, like “what should I look for in a good L-Arginine supplement?” and “why should I buy it on Amazon?”

Fear not! In this blog post, we'll break down the ABCs of L-Arginine supplements to make your shopping experience easier.

The Basics

First things first—what is l-arginine? It's an amino acid that plays an important role in heart health and muscle growth. It helps with circulation and can also boost immunity.

So why take an l-arginine supplement instead of getting enough l-arginine naturally through food sources like red meat? Well, if you're looking to improve your overall health and well-being, taking an l-arginine supplement can help you reach your goals faster than relying solely on diet alone.

Citrulline vs. L-Arginine

Now that you understand why l-arginine is so important for your overall health and well-being, let's talk about citrulline vs. l-arginine.

Citrulline is another amino acid that helps to improve circulation by increasing nitric oxide production in the body. Nitric oxide helps relax blood vessels and increases blood flow throughout the body which can help with muscle growth and improved cardiovascular health.

So which one should you choose? Both are effective but research shows that l-arginine may be more effective than citrulline when it comes to boosting nitric oxide levels in the body.

Third-Party Tests & NonGMO Certification

When buying any kind of supplement or medication, it's always a good idea to check if it has been third-party tested or if it has a nonGMO certification before purchasing it since these tests help ensure the purity and quality of the product you are buying.

Additionally, some companies will offer organic or pure versions of their product as well as potent versions that may have higher doses or concentrations than their competitors – both of these options can be beneficial depending on what your needs are!

Finally, consider buying from a reputable source such as Amazon – this way you're sure to get a quality product at a fair price point without worrying about scams or counterfeit products!


In conclusion, when shopping for an l-arginine supplement it's important to consider all factors including citrullines vs l arginines effectiveness; third-party testing; non GMO certification; organic/pure ingredients; potency; and where the product was purchased from (i.e., Amazon).

Doing research ahead of time will ensure that you get the best product possible while avoiding any potential scams or counterfeits out there!

Ultimately though – no matter which brand or type you choose – make sure it's something that works best for YOU!
