VigRX Nitric Oxide Support Review

Does VigRX really work? Is VigRX a scam? Can a simple supplement really boost sexual function? Today, we’re explaining everything you need to know about VigRX Nitric Oxide Support and how it works.

What is VigRX Nitric Oxide Support?

What is VigRX Nitric Oxide Support?

VigRX Nitric Oxide Support is a nutritional supplement that claims to boost sexual performance in men. You take 2 to 3 capsules per day to improve erections, enhance sexual desire, and boost stamina, among other benefits.

Like many other sexual enhancement supplements, VigRX Nitric Oxide Support claims to work by boosting nitric oxide production. Nitric oxide (NO) is a molecule that helps relax blood vessels and improve blood flow and blood pressure. Nitric oxide widens and relaxes blood vessels, making it easier for blood to flow in your body.

Some men take nitric oxide supplements to improve athletic performance. Many preworkouts boost nitric oxide production, for example. By widening blood vessels, NO enhances your pumps at the gym, making it easier to push your body further.

Other men take NO supplements to boost sexual function. By widening your blood vessels and lowering blood pressure, Nitric Oxide supplements can improve erection strength and other aspects of sexual function. For those who may be wondering, VigRX Plus is one of the leading male enhancement supplements for sexual health on the market today, and the new NO2 boosting formula is one of the most popular newly released products by Leading Edge Health.

Let’s take a closer look at how VigRX Nitric Oxide Support works.

How Does VigRX Nitric Oxide Support Work?

How Does VigRX Nitric Oxide Support Work?

VigRX Nitric Oxide Support claims to boost nitric oxide (NO) production in the body. By raising nitric oxide levels, VigRX claims to widen blood vessels, lower blood pressure, and improve sexual function, among other benefits.

You can find plenty of similar supplements that claim to support nitric oxide production using herbal extracts or amino acids like L-arginine. So how does VigRX raise NO levels?

Oddly, VigRX does not disclose its full list of ingredients or dosages upfront. You cannot see the supplement’s ingredient label before you buy.

We do know, however, that VigRX contains two amino acids: L-citrulline and L-arginine. Here’s how the company describes these two ingredients:

“Studies clearly show the combination of L-Citrulline and L-Arginine drastically outperforms supplementing with just L-Citrulline or L-Arginine alone…[VigRX] is formulated with the maximum dose of L-Citrulline and L-Arginine to safely and effectively increase N.O.”

As far as we can tell, there are no other listed ingredients in VigRX Nitric Oxide Support.

The lack of other ingredients is unusual. VigRX claims to enhance your libido, for example, yet doesn’t claim to contain any ingredients that do so. L-citrulline and L-arginine may widen blood vessels, but they have not been shown to improve libido. Some supplements contain herbal extracts or similar formulas to boost libido.

Scientific Evidence for VigRX Nitric Oxide Support

There’s evidence showing that the two active ingredients in VigRX (L-citrulline and L-arginine) boost nitric oxide levels when used at certain dosages.

However, VigRX Nitric Oxide Support refuses to disclose its dosage information upfront, making it impossible to determine if the supplement contains the right dose of the amino acids – or a much lower dose.

Typically, you take L-citrulline and L-arginine in the form of a powder, taking 2g to 6g of each to widen blood vessels before a workout.

Scientific Evidence for VigRX Nitric Oxide Support

VigRX Nitric Oxide Support, however, comes in a small capsule, which means it contains a much smaller dosage than a scoop of bulk powder. Typically, a capsule can contain about 500mg of formula.

Science also tells us that NO boosters work on some people – but not others. If you already have healthy levels of nitric oxide in your system, then a nitric oxide booster will not raise NO levels. If you have low levels of NO, however, then you may notice certain benefits.

Studies have also been small. This study cited by VigRX, for example, involved just 24 men with erection issues. Those men improved erection hardness by taking 1.5g of L-citrulline per day.

Another study published in 2010 involved just 41 men: men took 8g of citrulline malate, then improved strength training performance.

Furthermore, VigRX claims to have no side effects whatsoever, yet cites studies that revealed significant side effects. In one cited study, researchers reported that 15% of participants experienced stomach discomfort after taking L-citrulline.

Overall, L-citrulline and L-arginine have shown some ability to widen blood vessels when taken at dosages above 2g each. However, there’s no evidence that VigRX Nitric Oxide Support contains a strong dose of either ingredient. You can find plenty of L-citrulline and L-arginine supplements online for a fraction of the price at a higher dose.

Final Word

VigRX Nitric Oxide Support is a high-end sexual health supplement that claims to widen blood vessels and lower blood pressure to boost your sexual performance. VigRX Nitric Oxide Support contains two active ingredients, including L-citrulline and L-arginine.

Both ingredients have been shown to widen blood vessels in certain studies. VigRX Nitric Oxide Support may need a second look at its dosages and potency of each ingredient, but knowing who the product comes from and their attention to detail when formulating new working products for men (and women), there is almost no risk at all when using this supplement given the return policy and company reputation.

Overall, you can buy good L-citrulline and L-arginine supplements online for under $30, including supplements with higher dosages and a better reputation. However, to get the synergistic effect of including the additional elements, it is often way better to use individual ingredients together so they can amplify each other's properties. While most sexual health products for men offer no evidence to support their claims, VigRX Nitric Oxide Support does reveal how its formula works to improve sexual function overall.
