Superior Labs VasoWORx

VasoWORx comes from a well-established manufacturer, Superior Labs, that is backed by third-party monitoring services and manufactures its supplements in the United States. We like that it contains clinically-proven ingredients and has many positive customer reviews.

VasoWorx contains only 3 of our must-have ingredients, L-arginine, L-citrulline, and Quercetin. While these ingredients are key for increasing Nitric Oxide production in the body, it is disappointing to note the lack of other beneficial ingredients, such as Beetroot, Fenugreek, and Pine Bark. Another major drawback of this product is that it only contains one type of L-arginine, and the dose falls below the recommended minimum of 1500mg per serving, which makes it hard to determine the effectiveness of this product.

It is promising that this product undergoes rigorous third-party testing and comes with many reviews from satisfied customers, however, Superior Labs do not offer a money-back guarantee, which is usually a sign that the manufacturer doesn’t have much confidence in their product.

CrazyBulk Nitric-Max

CrazyBulk Nitric-Max is based on the powerful benefits of L-arginine for boosting Nitric Oxide production in the body for optimal workouts, providing a 1800 mg daily dose. However, that is all that this product contains making it a bit of a disappointment. 

This product offers some great perks such as free shipping worldwide and fast delivery in the United States, however, for the hefty price tag, it is disappointing that this product only contains L-arginine as its sole Nitric Oxide boosting ingredient. We like that it is vegetarian-friendly and does not contain any gelatin, though. 

This manufacturer seems geared to the workout industry, however, it is unfortunate to note that they don’t offer any guarantee on their products. They state explicitly on their site that once you have opened a product, you cannot return it. The lack of other Nitric Oxide boosting ingredients, no money-back guarantee, and high price, are what held this product back from really shining.
