The internet doesn’t take days off when it comes to marketing the best new things for your penis. But the truth is, many herbal supplements and other “natural remedies for ED” aren’t exactly the safest substances to put in your body. 

While some products may increase blood flow to your equipment, they can also put you at higher risk of allergic reactions and serious side effects — including huge dangers for things like chest pain and heart attack.

This brings us to Nizagara — a so-called sildenafil citrate supplement you may have seen in banner ads. It’s sold in India (but not the United States) and touts the active ingredient in Viagra® (sildenafil).

Before you “buy Nizagara now” from a sketchy website, you may want to know how safe this product actually is. 

Below, we’ll cover what it is, how it compares to other medications for ED and what experts recommend on the “take Nizagara” or “avoid Nizagara” question.

Nizagara is a pretty tricky medication to track down real facts about. According to various online listings, it calls itself a Viagra supplement and is available in several dosages.

Nizagara 100 mg is a 100-milligram dose of the medication.

In addition to the active ingredient sildenafil, Nizagara contains various vitamins and nutrients like L-arginine, redberry, vitamin B6, vitamin B12, and folic acid. However, it’s hard to confirm the exact ingredients, as it’s not an FDA-approved medication.

Its medical claims are basically non-existent. But based on the ingredients listed, the product’s manufacturers suggest it can improve sexual activity, help you achieve erections and have enjoyable sexual intercourse — often for less than the cost of real Viagra.

Despite these claims, there’s zero research to support the safety or effectiveness of Nizagara, specifically.

Many of the ingredients it contains are suggested to have health benefits — including some adjacent to your sexual health. But while you technically get the active ingredient in Viagra, plus a multivitamin, for less than the price of Viagra, there’s a catch.

Nizagara’s claims are thoroughly unfounded, unproven and unsubstantiated. The studies and data supporting the medication are really just evidence from studies of its ingredients — not independent reviews of Nizagara itself.

In the United States, ED medications approved by the FDA (Food and Drug Administration) must undergo strict testing, have their dosages carefully maintained and meet rigorous CGMP quality and safety standards. Supplements, on the other hand, are generally not held to the same level of standards.

In other words, there’s a big difference between taking a 100-milligram tablet of Viagra and a 100-milligram tablet of Nizagara — starting with the fact that you may not get exactly 100 milligrams of the medication.

When you combine that with the potential of other ingredients magnifying or interfering with a sildenafil dosage, you get into some really dangerous territory.

genuine Viagra® makes it possible

Let’s assume for a moment that Nizagara does indeed contain a precise dose of sildenafil. If that’s the case, users could already risk side effects, including:

  • Low blood pressure

  • Irregular heartbeat

  • Lightheadedness

  • Indigestion

  • Stuffy nose

  • Increased risk of impairment from alcohol

Loss of vision is a very serious and rare side effect of sildenafil. Those with retinitis pigmentosa (a genetic disease that causes vision loss) shouldn’t take sildenafil, as it can worsen existing retinal damage.

Heart failure is also a major risk for people taking sildenafil who have existing cardiovascular disease.

Likewise, it could make for serious dangers if you take other medications. Drug interactions between sildenafil and other medications for ED and high blood pressure can increase your risk of heart failure and other side effects. 

You’d be very smart not to use Nizagara, but if you do, avoid mixing it with:

  • Nitrates

  • Alpha-blockers

  • Alcohol

  • Other ED meds

  • Medications for angina and arterial hypertension

You’re also wise to talk with a healthcare professional before using Nizagara if you have high blood pressure, Peyronie’s disease or any other medical conditions affecting your heart or penis.

But all these warnings are based on an assumption that what’s in the pill is what the makers say is in it — and this hasn’t been vetted by anyone we trust to give medical advice.

The only places you can find Nizagara info are the same places trying to sell it to you. Those websites feature 2006-style web designs, and they’re laden with typos, without a single word from a trusted medical organization.

Taking Nizagara isn’t substantially different from taking other unvetted products like “natural Viagra” or “herbal Viagra” in terms of risks.

At best, Nizagara is a Viagra pill with vitamins. But without someone overseeing its production, it’s just a game of Russian roulette, pill by pill.

Choose your chew

Sildenafil is both the active ingredient in and generic version of Viagra. It’s one example of a phosphodiesterase type 5 (PDE5) inhibitor — a drug that keeps you hard by keeping the blood vessels in your penis dilated and your corpora cavernosa engorged long enough for penetration.

When it’s FDA-approved and manufactured appropriately, sildenafil is considered an effective ED medication.

We realize some people look for alternatives due to cost. Luckily, generics are available:

Each of these medications works slightly differently. They come with side effects similar to those listed above but with a lower risk of danger from poor manufacturing quality or contraindications from unlisted ingredients.

Talking to a healthcare provider about sexual function problems can be embarrassing, leading many men to unproven internet pills as a possible solution.

We get it — but we’d like to remind you that the very real risk of dying from a poorly made ED pill would be pretty embarrassing, too.

You shouldn’t avoid professional help, and you shouldn’t ignore your ED, either.

For what it’s worth, ED is more common than you may think — an estimated 30 to 50 million men nationwide have erectile dysfunction.

So before you press “Buy now,” keep these things in mind about Nizagara:

  • Alternative ED medications from the internet, gas stations or supplement stores labeled as over-the-counter “Viagra” aren’t always safe. 

  • Nizagara might seem like a vitamin-rich version of Viagra, but there’s no research to back its claims — or even to convince us it’s safe.

  • Viagra is safe, but pills won’t always correct the problem. Stress, anxiety or underlying depression can cause ED, as can issues with sexual stimulation.

  • A healthcare provider can identify the cause of your erectile dysfunction and help you find the right treatments.

  • Talk to a provider who can treat both the symptoms and the underlying cause. This may save you from blood pressure or nutritional problems that could have far wider and more damaging impacts.

Erectile dysfunction can be scary, and due to the stigma, almost nobody wants to talk about having stamina or performance problems. But getting the problem solved is the only solution.
