Zyrexin Review 2019: Is this Your Ultimate Sex Booster?


A short intro to Zyrexin

One of the most worrying things facing men today is the state of their sexual performance.

An increasing number of men are hitting the brick wall when it comes to libido and ability to perform in the bedroom. So grave and important is this issue that it has given growth to a $32 billion industry devoted to helping men with male enhancement.

But how well does this $32 billion value deserve in terms of delivering results and getting men out of their agony? 

Zyrexin is just one of many supplements that promise to deliver you into the promised land of great and stunning sex. It has no hesitation calling itself the world’s greatest male sex enhancement supplement.

In this article, I will help you look into the product’s claims and whether it’s a solution to your situation.



Zyrexin is manufactured by Superbalife Interantional LLC, a company that is located in Los Angeles, California. Founded in 2004, this company specializes in nutraceuticals or food-based products that aim to benefits people’s health.

The company’s products are aimed mainly at men.

Superblife International makes a big point of the fact that it has FDA certification. Keep in mind, however, that this certification, while important, is only used to ensure that the packaging is correct according to the labeling.  It also makes sure that the production process is hygienic. However, it does not indicate the efficacy of the product.


Zyrexin could be the long lost product that men have been looking to supercharge their sex life or to give them that explosive sexual energy that is so essential to their manhood. But what are the benefits that make this product worth your time?

The company makes very interesting claims that should make most men sit up and take notice

  • Works rapidly within just 35 minutes of taking it
  • The effects will linger for almost 24 hours, which can comfortably accommodate all the time most men would need to be sexually active.
  • you see the results with the first try and with every subsequent time
  • no side effects have been noted
  • is effective

Side effects

Even though the manufacturer of Zyrexin say that no side effects have been seen despite users using this supplement more than 100 million times, some users have reported some side effects. These range from slight or mild to more severe cases.

  • headaches
  • stomach problems
  • Constipation
  • Dizziness

Individual ingredients have also been associated with side effects based on studies. For example, Yohimbine will give you

  • Troubled breathing
  • Painful prolonged Erection
  • Fast heartbeat

Besides, velvet beans can give you

  • Bloating
  • Nausea
  • Vomiting

As for Arginine, you may have

  • Bloating
  • Gout
  • Diarrhea
  • Inflamed airway
  • Abdominal pain

These side effects are, however rare and come mostly from overdosage. Most healthy adults typically don’t get them provided they keep to the dosage.


What are the ingredients of Zyrexin?  The ingredients of Zyrexin are the following :

•           Epimedium or horny goat weed – this extract, with a long Chinese tradition and usage in driving libido is widely used to overcome erectile dysfunction. It has a very interesting history because it was discovered by a farmer who noticed strong sexual arousal in goats that were feeding on the plant. This gave rise to its revealing name. The weed’s action is due to an active ingredient called icariin. Icarian has an inhibiting effect on PDS, a natural compound in your body. Poor blood circulation in the genitalia is usually attributed to PDS. Its blockage by icariin can unleash powerful sexual vigor due to increased blood flow and Erection.

• Yohimbe – This extract from an African tree bark gives Yohimbine, used in therapy as Yohimbine hydrochloride as a prescription for erectile dysfunction. It is clinically tested to be effective. However, for it to be effective in supplements as well, its amount needs to match those found in prescriptions. Unfortunately, Zyrexin does not state how much Yohimbine it contains, so it is impossible to know if it has this amount.

• Xanthoparmelia scabiosa extract – this is a lichen substance, a cross between algae and a fungus. It can enhance libido and abs help to combat erectile dysfunction. It makes the sexual organs more sensitive triggering easy arousal.

•           L-Arginine – This amino acid is recognized for stimulating the production of Nitric oxide, a compound that can elevate blood supply around the body.

• Ginkgo extract – also known as Ginkgo Biloba, this has been a long-cherished secret for treating old-age symptoms, including sagging sexual power. Many cultures have used it, and high-status people, including royals, favored it for overcoming problems of senility.

•           It is a powerful antioxidant because it contains terpenoids and flavonoids, two well-known antioxidants. Antioxidants are valued for their protective role of cells against damage by free radicals.

• Supplementing with Ginkgo leaf extracts has also extended benefits like treating eye conditions and relieving pain in the legs caused by narrow arteries.

•           Velvet beans – also known as mucuna pruriens, this African and Asian legume has traditionally been used animal feed and also to increase soil fertility through nitrogen fixation. Its main active ingredient in Zyrexin is K-DOPA. However, some people have reacted negatively to it through vomiting, nausea, and cramps. Velvet beans have been considered as aphrodisiacs by many communities and in dealing with infertility. Studies have confirmed its role in treating infertility as well as improving sperm quality.

Butea Superba Extract – this herb which is native to India, Vietnam, and Thailand is what the makers of Zyrexin say gives it its ultimate sex boosting power. Thai men are said to have seen their sexual vigor soar from this plant which is rich in flavonoids and sterol. Many supplements include Butea Superba in their formula to help men achieve better erections

•           Gamma Amino Butyric acid – this gives a euphoric sense by increasing dopamine levels. This can add to sexual pleasure and excitement

• Cnidium Monnier – this Chinese based species, as well as a native to some parts of the US, has traditionally been valued for its skin healing properties. Many skin solutions include it in their formulations. However, it has also found use in sexual enhancement and improvement of the libido. It has also been used to deal with erectile dysfunction

A closer look at PDE-5 inhibitor

At the heart of the Zyrexin’s formulation is Butea Superba, which the company states are the only PDE-5 known to exist in nature. But what is a PDE-5 inhibitor?

This substance is the one that prevents cyclic guanosine monophosphate (cGMP) from breaking down. This is critical because cGMP works to keep blood vessels wide, thus maintaining blood circulation at an optimum level.

PDE-5 inhibitor only acts on a type of cGMP found in erectile tissue called type-5 phosphodiesterase. Erectile tissue is found in the penis as well as the lungs.


The recommended dosage of Zyrexin is 1 to 2 pills per day. Take these pills about 45 minutes before you engage in sex. Never exceed this upper limit of 2 pills

Price and availability

Zyrexin can be bought from the manufacturer’s official site. There are also many other retailers like Walgreens, Walmart, Rite Aid, and CVS pharmacy.

The company offers you great savings if you buy large quantities. Here us a look at their offers keeping in mind that there are 10 pills in a bottle

  • 2 bottles $29.95
  • 2 bottles for $59.95 fetches you an extra free bottle
  • 3 bottles for $89.95 gets you 2 free bottles

There is Zyrexin, and then there is Zyrexin ultra

What’s the difference?  Both products come from the same company. Zyrexin has a few more ingredients added so naturally, that adds to a higher price. But you won’t get much further with it compared with the plain Zyrexin as the difference is minimal.

Who shouldn’t use Zyrexin

  • pregnant or suckling mothers
  • those under 18
  • if you have high blood pressure
  • if you have heart problems
  • Not suitable for people with anxiety or bipolar disorder. It can escalate the symptoms


  • Includes ingredients proven to improve infertility in men
  • Can boost your energy
  • Has wide and popular recognition


  • Many users say they did not see any benefits
  • product has a proprietary formula so users cannot tell the quantities or doses used
  • has some side effects


There is no doubt that some of the ingredients in Zyrexin have proven efficacy in improving your sexual performance. However, can this supplement, given its formulation, get you these desired results?

10 pills in a bottle is a rather miserly amount, but to pay the price being charged makes little sense.

Another problem is the inclusion of ingredients like Yohimbine. This otherwise powerful substance can rev your sexual drive, but it also comes with grave downsides, especially when it is in large quantities.

Zyrexin is a popular product but one which overall does not live up to its hype. I find it claims to be the world’s greatest sexual booster and male enhancer dubious. There are certainly other supplements with much better-researched efficacy
