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

Nizagara is a sildenafil citrate supplement sold in India but not the United States. It touts the active ingredient in Viagra® (sildenafil), but that doesn’t mean it’s as safe, effective, or legal.

Some ED supplements may increase blood flow to your equipment but can also put you at higher risk of allergic reactions and serious side effects — including for things like chest pain and a heart attack. Nizagara certainly makes this list.

Below, we’ll cover what it is, how it compares to other medications for ED, and what experts recommend about whether to take or avoid Nizagara.

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

Nizagara 100 mg is a 100-milligram dose of the medication, sold as a tablet.

In addition to the active ingredient sildenafil, Nizagara contains various vitamins and nutrients like:

  • L-arginine

  • Redberry

  • Vitamin B6

  • Vitamin B12

  • Folic acid

However, it’s hard to confirm the exact ingredients since it’s not an FDA-approved medication.

While Nizagara can’t make any real medical claims, manufacturers suggest these ingredients can work together to improve sexual activity, help you achieve erections, and have enjoyable sexual intercourse — often for less than the cost of actual Viagra.

Same ingredient as Viagra®, 95% cheaper

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

We know that the active ingredient in Nizagara is effective and many of its ingredients might 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 evidence from studies of its ingredients — not independent reviews of Nizagara itself. That means we don’t know how these ingredients interact or if they have different side effects when used together.

In the United States, ED medications approved by the Food and Drug Administration (FDA) must undergo strict testing, have their dosages carefully maintained and meet rigorous quality and safety standards.

On the other hand, supplements are generally not held to the same level of standards — and that’s the category that Nizagara falls into.

Furthermore, it can be hard to navigate all the supplement options because there are so many names for just a few ingredients. 

You may have heard of bestsellers like:

  • Cenforce Soft

  • Cenforce-D

  • Fildena

  • Kamagra Effervescent

  • Kamagra Gold

  • Kamagra Oral Jelly

  • Malegra

  • Suhagra

  • Super P-Force Oral Jelly

  • Silagra

  • Vidalista

  • Tadora

  • Kamagra Polo

Like Nizagara, these are all unregulated and potentially very risky.

ED treatment personalized

There’s a big difference between taking a 100 milligram tablet of Viagra and a 100 mg tablet of Nizagara — starting with the fact that you may not get exactly 100 milligrams of an active ingredient in the Nizagara tablet.

When you combine that with the potential for other ingredients to magnify or interfere with a sildenafil dosage, you get into some really dangerous territory. 

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

  • Low blood pressure

  • Irregular heartbeat

  • Lightheadedness

  • Indigestion

  • Stuffy nose

  • Increased risk of impairment from alcohol

Loss of vision is a severe 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 significant 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 the assumption that what’s in the pill is what the makers say it is — and for Nizagara, 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 are 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.

Sildenafil is both the active ingredient in and the generic version of Viagra. It’s a phosphodiesterase type 5 inhibitor (PDE5 inhibitor), which is a type of 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 and safe ED medication.

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

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

ED Treatment

Enjoy sex like you used to

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