Zyrexin is a blue pill made for men with difficulty achieving an erection.It uses a blend of natural ingredients to produce erections in men in less than an hour.Zyrexin is said to work "the very first time" a man uses it.Our research team decided to see what they could find out about Zyrexin and how well it works.
Although the product is widely sold,the research team was immediately concerned about the lack of scientific research that has been conducted using some of the ingredients.After that,they looked at potential side effects,the background of the makers,and what users of Zyrexin are saying.Finally,we wrapped all of the information into this concise report that brings you all the information you need.
Zyrexin is a supplement used to help men with erectile dysfunction achieve erections.It is made with a tuber vegetable used in traditional medicine as an aphrodisiac.
Zyrexin comes as a blue capsule and claims impressive results in just 35 minutes.The effect is supposed to last for 24 hours,which means that men should be able to take it at any time of the day and still be ready for six hours later.
The makers of Zyrexin say that it is the only natural mixture to receive a patent in the United States for use as a male enhancement product.But,here's the thing,having a patent doesn't necessarily mean that a product works.It only says that the makers are protecting it from being copied by other companies.
How Did Zyrexin Start?
Zyrexin comes from a company called Superbalife International LLC.The company is based in Los Angeles,CA and was founded in 2004.Superbalife makes nutraceuticals,which are products made from food sources that are supposed to have health benefits.They specialize in creating products specifically for men's health.
The official website says that their products are all made in the United States in facilities that are inspected by the FDA.(Note: This does not mean the products themselves are FDA approved,only that the FDA makes sure their products are packaged correctly and the manufacturer follows safety rules.)
The company is not currently accredited by the Better Business Bureau (BBB).It also does not have a BBB rating.While BBB accreditation is voluntary,when a company is accredited,it shows a commitment to sound business practices and a commitment to its customers.
Although there are no reviews of Superbalife International LLC on the BBB's website,there are four complaints filed against the company.Three of the claims have to do with the company's products or services.One is about billing issues,and the remaining charge is about delivery.

The claims made about Zyrexin are impressive.If they prove true,Zyrexin might be the miracle pill that men are looking for.The Zyrexin claims include:
Works in as little as 35 minutes
The effects last for 24 hours
Works the first time it is used
No side effects
The official Zyrexin website states that the supplement contains a natural PDE-5 inhibitor.The official website does not provide an image of the label or even a complete list of ingredients.The only ingredient they disclose is something called Butea Superba.In reality,the supplement contains much more.
According to the product's label,it contains a proprietary blend of herbs.Some of the ingredients in the combination are:
The makers of Zyrexin say that Butea Superba is "the only natural PDE-5 inhibitor know [sic] in nature." A PDE-5 inhibitor is a substance that stops cyclic guanosine monophosphate (cGMP) from breaking down.This allows blood vessels to remain dilated so that blood flows more smoothly.PDE-5 inhibitors work individually on type-5 phosphodiesterases,a form of cGMP that exists in the erectile tissue of the penis and the lungs,LiverToxclaims.
Does Zyrexin Work?
Zyrexin promises outstanding results but whether it can deliver depends on whether there is clinical evidence to show the ingredients are active.The Zyrexin website doesn't provide any links to studies using the supplement or any of its elements.However,our research team took the time to look into the science behind the ingredients.Here is some of what they found.
Yohimbe is a kind of tree that grows in parts of Africa.The bark of the tree contains yohimbine,which is used in a standardized form (yohimbine hydrochloride) to make prescription medications for erectile dysfunction.
Although yohimbine has been proven effective,there isn't much research concerning Yohimbe used in dietary supplements.Also,according to theNational Center for Complementary and Integrative Health,dietary supplements that contain Yohimbe vary in the amount of yohimbine in them.They also state,"Yohimbe sold as a dietary supplement may not work like the prescription medication that contains yohimbine."
The amount of Yohimbe,or its active ingredient yohimbine,is not disclosed on the Zyrexin label.It is only listed as one of the ingredients in the proprietary blend.Therefore,there's no way to know if there's enough of the substance to have any effect.
Ginkgo,or ginkgo biloba,is an ancient tree species.It's believed to be one of the oldest species of tree known to humankind.Although the seeds are poisonous,they were once given to royalty to treat senility.
According toMedicalNewsToday,gingko is thought to have health benefits because it contains flavonoids and terpenoids,which are both antioxidants.Antioxidants help to protect cells from free radicals.
Today,ginkgo extract made from the leaves of the tree is used in supplements to treat:
Leg pain due to narrowing arteries
According to theNational Center for Complementary and Integrative Health,there have been some studies conducted using ginkgo to determine if it has health benefits and how it affects people.The studies have yielded "no conclusive evidence that ginkgo is helpful for any health condition."
Velvet Bean Extract
The velvet bean,or Mucuna pruriens,is a kind of legume that grows in Africa and Asia.It is often grown as a green manure crop because it fixes nitrogen in the soil.Also,it is used as silage for livestock.
Velvet bean contains a substance called L-DOPA.People who are sensitive to L-DOPA may experience problems when taking the substance,such as nausea,vomiting,and cramping.They may even have an erratic heartbeat.
In traditional medicine,velvet bean has been used to treat infertility and as an aphrodisiac.
Some studies indicate velvet bean may be useful in treating fertility problems.A study published in a journal titledFertility and Sterilityindicates that velvet bean may improve sperm quality.The study involved 75 men with fertility problems and 75 men without fertility problems.The subjects were treated with mucuna pruriens.After the study,the researchers determined that taking the substance "regulates steroidogenesis and improves semen quality in infertile men."
Butea Superba Extract
Butea Superba is the ingredient that the makers of Zyrexin give all the credit to on their website.It is a shrub that grows in Thailand,Vietnam,and India.The roots of the plant are tuberous and contain flavonoids and sterol compounds.In traditional medicine,Butea Superba is used by Thai men to boost sexual vigor.
Although it is used in supplements to help men achieve erections,at present there is not enough evidence to show that it is effective,WebMDsays.
Researchers published a study in the journalBJU Internationalthat showed the results of Butea Superba are inconsistent at best.An initial investigation showed positive effects on erectile dysfunction.However,a second double-blind study failed to duplicate the results.The researchers believed that the first batch of Butea Superba used had been mixed with a PDE-5 inhibitor.Their suspicions were later confirmed by the company that supplied the substance.
L-arginine is an amino acid that the body uses for proper blood flow.According toExamine,however,research shows that taking a supplement containing l-arginine may not have that same effect.Studies show that although l-arginine supplementation might activatenitric oxide,its effects are not reliable.This means that it is also not reliably useful for increasing blood flow.
Zyrexin Benefits and Results
Even though the makers of the supplement say that the Zyrexin benefit is men being able to achieve erections,our researchers didn't find any clinical research to support that claim.Men who take Zyrexin may benefit from the antioxidants in a few of the ingredients,but that's about it.
How to Take Zyrexin
The instructions for Zyrexin say that men should take one or two tablets about 45 minutes before sexual activity.Men should not take more than two tablets per day.
Potential Zyrexin Side Effects
The makers of Zyrexin say that the product has been "taken over 100 million times…without any reports of side effects." The customer comments we read indicate that's not the case.As with any supplement,some people may have no problems when taking it,but others might experience anything from mild side effects to ones that are concerning.
Some of the potential side effects of ginkgo are:
Also,theMayo Cliniccautions against certain groups of people using supplements containing ginkgo,such as:
Women who are pregnant
WebMDsays that Yohimbe can interact with certain medications,including blood thinners medications.It also should not be taken by people with Seizures.
Possible side effects of Yohimbe are:
A painful erection that does not go away
According toWebMD,velvet bean is considered "possibly safe" for most people when taken by mouth.However,it can cause side effects like:
AsWebMDreports,some of the side effects associated with l-arginine are:
As for Butea Superba,there just hasn't been enough research conducted to determine if the substance is safe for human use,WebMDclaims.
Zyrexin Product Warnings
The Zyrexin label says that the product should not be used by anyone under the age of 18 or by women who are pregnant or nursing.
Where You Can Buy Zyrexin
Zyrexin can be purchased through the official website.It is also available through several retailers,including:
What Does Zyrexin Cost?
The official website offers package deals to reduce the Zyrexin cost.At the time of this review,the Zyrexin deals are:
Buy two bottles for $29.95.
Buy two bottles for $59.95 and get one bottle free.
Buy three bottles for $89.95 and get two bottles free.
Those might sound like good deals until you find out that each bottle contains only ten pills.
Any Zyrexin Lawsuits?
The research team didn't find any lawsuits associated with Zyrexin.However,theCanadian governmentdid issue a "Foreign Product Alert" because the supplement contains yohimbine,the active ingredient in Yohimbe.In Canada,yohimbine is a prescription drug and should not be taken without the advice of a doctor.
Is Zyrexin a Scam?
We hesitate to call Zyrexin a scam as there doesn't appear to be any evidence of questionable business practices,which is usually the hallmark of fraud.However,we aren't convinced that the supplement will help men with erectile dysfunction.Instead,it appears to be an overpriced herbal supplement with little effect.
There's no shortage of male enhancement products on the market,and many of them claim to help men with erectile dysfunction.Some Zyrexin alternatives are:
Experts at theMayo Clinicsay that it's normal for men to have difficulty getting an erection once in a while.However,if the problem is ongoing,you should talk to the doctor as it may be caused by an underlying condition.Possible underlying causes include obesity.
Bottom Line on Zyrexin
Is it time to run to the store for a bottle of Zyrexin?We don't think so.It's true that there is evidence suggesting that some of the ingredients might improve fertility but not that they help with erectile dysfunction.The information our research team discovered left us with some concerns,such as:
Many customers reported having uncomfortable and even frightening side effects.
We found little evidence suggesting the ingredients in Zyrexin do anything to allow men to achieve erections.
Considering there are only ten pills in a bottle,the cost is quite high.
Believe it or not,there are plenty of similarities between weight loss and muscle building.That's why we believe making lifestyle changes like eating right and exercising can benefit from a clinically-proven app.
Among the best lifestyle apps we've come across this year isNoom.Promoting muscle growth requires exercise and healthy meal choices with plenty of lean protein.Noom helps with human coaching,personalized meal plans,food and exercise tracking and more.
