There’s so many options!

What’s the difference between these nootropics?

Maybe you’re ready to make your first Modafinil order, but you want to get your hands on the best nootropic possible.

You just don’t know which exact supplement to choose.

That’s where I come in.

See, both smart drugs are somewhat similar, but the differences between Armodafinil and Modafinil are recognizable.

After testing, I have a definite preference – but other smart drug users disagree.

Ideally, you’ll test out both smart drugs and make the choice for yourself. The Armodafinil vs. Modafinil debate will be easily solved once you’ve tried both nootropics.

Your body and chemistry will tell you which smart drug works best for you.

The issue is sometimes money is tight. You may want to only order one type of nootropic. I get that. When I first started, I ordered a little Modafinil to test it out and they moved on from there.

If that’s you, then keep reading. I’ll help you detail the differences between Modafinil and armodafinil – along with figuring out which one is best for you.

Everything you need to know is covered here.

I’m no doctor. Not a lawyer, either. Before consuming any smart drugs or pharmaceuticals – like Modafinil and Armodafinil – make sure to consult with a medical professional. This is not advice – only for entertainment purposes. Please read my full disclaimer too.

What is Modafinil

What is Modafinil?

Modafinil, also known as Provigil, was developed in France. Originally, the pharmaceutical drug was developed to treat narcolepsy (Source).

The drug quickly gained stream, as doctors realized Provigil was fantastic treating sleep apnea and shift sleep disorder, too.

Shortly thereafter, many an entrepreneur found the pharmaceutical drug to be beneficial for cognition, focus, and productivity.

Nowadays, Modafinil is widely considered a smart drug used by digital nomads, CEOs, and students around the world.

Hell, most consider the stuff to be the most popular smart drug in the world.


Mainly because Modafinil just works!

What is Armodafinil? 

The company that developed Modafinil created Armodafinil, or Nuvigil, in 2007.

Modafinil’s patent had run out, so the pharmaceutical company created a new drug with similar effects, but a different chemical structure.

Armodafinil is enantiomer of Modafinil. This means that Modafinil contains the “R” and “S” enantiomers, while Nuvigil only contains the “R” enantiomer.

Due to the minor chemical changes, the company could get another patent for the new drug. As well, Armodafinil offers higher plasma concentrations throughout the day.

As such, some claim Armodafinil is a “pure” form of Modafinil or that the nootropic is stronger than it’s cousin.

The reality of the situation…

Well, that all depends on what smart drug works best for you.

With regards to the Modafinil vs. Armodafinil debate, I’ll break it down in detail below. But do know, there’s no “right” answer here.

Modafinil vs. Armodafinil: Similarities?

Modafinil vs. Armodafinil. Provigil vs. Nuvigil. Same thing, but with different names.

Luckily, it doesn’t matter what the name is – these smart drugs are fairly similar in a plethora of ways.

You’re going to find insane cognitive benefits from both Modafinil and Armodafinil.

But here’s are a few more commonalities:

~ Focus, Cognition, & Productivity

Personally, I found the main benefit of both Nuvigil and Provigil the same – improved brain power. On either smart drug, you’ll be able to crush your work, stay focus, and get a ton of stuff done.

This is why people take smart drugs like Modafinil and Armodafinil – the brain boost!

The effects in this regard are similar, as the compounds themselves are quite similar.

Personally, I found Modafinil to be a little stronger overall. However, others have said they feel more focus after taking Armodafinil.

If you want to make more money or get better grades and need to improve your focus and cognition, both of these nootropics will help you.

~ Solid Half-Life

Both of these smart drugs feature a similar half-life.

While some argue Armodafinil will last one or two hours longer, most users don’t experience much of a difference.

Depending on your dosage of Modafinil or Armodafinil, you’ll experience the effects of the pharmaceutical drug for 9-15 hours. For most dosages, the half-life is around 10-12 hours.

This means your brain will be more than enhanced for a full work day.

Armodafinil and Modafinil - The BIGGEST Differences

Armodafinil and Modafinil: The BIGGEST Differences

While the similarities between these nootropics are striking, there are some distinct differences.

It’s important to note that every user reacts to smart drugs differently. Some may disagree with my statements regarding the differences of Armodafinil and Modafinil.

However, these are simply what I noted after testing the smart drugs. Other users may experience different results.

Here are a few of the differences between Modafinil and Armodafinil I found:

~ Sleep Effects

I found it MUCH easier to fall asleep after taking Armodafinil compared to Modafinil.

With similar timing and dosing, I fell asleep about 2-3 hours earlier when taking Armodafinil – which was a huge surprise. Nuvigil simply didn’t disrupt my sleep as much as Provigil did.

On the flip side, if you’re trying to stay up all night or work late hours, then Modafinil may be a better choice – as it’s nearly impossible to fall asleep after taking the smart drug.

~ Feel-Good Feelings

Modafinil often produces a feel-good state It’s basically like a small high that makes working on tedious tasks somewhat enjoyable.

Personally, I like this aspect of my favorite nootropic.

With Armodafinil, I never had similar feelings. There was no “high” feeling for me. Just a smooth, focused energy.

This isn’t a huge deal, but definitely a plus for Modafinil in my book. Others may disagree.

~ Side Effects

Modafinil seems to have more side effects.

Personally, I struggle to sleep on Modafinil and often have an upset stomach. Others have experienced similar, albeit minor side effects.

After taking Armodafinil, I didn’t have any stomach issues and sleeping was much easier.

As Nuvigil is a bit “weaker” for me, it wasn’t a surprise that the side effects seemed to disappear, too.

~ Tolerance & Dosing

If you take 200 mg of Modafinil, you’ll only need about 150 mg of Armodafinil to feel similar smart drug effects.

Armodafinil is “purer” than Modafinil due to the single enantiomer structure. With Nuvigil, less seems to be more.

From a tolerance perspective, Modafinil seems to be slightly more addictive. Neither smart drug is habit forming whatsoever, but it’s easier to start depending on Modafinil than Armodafinil.

Using Nuvigil on a daily basis may be a better idea, as there are fewer side effects. Modafinil must be cycled properly, or issues could arise.

Armodafinil vs Modafinil - Which is Better for you

Which is Better For You?

Again, I must reiterate that this is simply my opinion after using both nootropics.

Personally, I see the Armodafinil vs. Modafinil debate like this:

  • Try both smart drugs and see which one you like better – if you have the funds.
  • If you want to really crush work 1-2 times a week, then Modafinil may be the better choice. I found the cognitive effects slightly stronger and with proper cycling, I prefer it.
  • For regular smart drug use, think 3-6 days a week, Armodafinil is the better choice. There are fewer side effects with this nootropic and it’s easier to get to sleep.

Overall, you can switch between these smart drugs pretty easily too.

You don’t have to just choose one.

If you’re talking smart drugs a couple days a week, take Modafinil on one day and then take Armodafinil on the other.

This will help with tolerance issues and keep the benefits of both smart drugs intact for you personally.

Armodafinil vs. Modafinil

Overall, it’s best to try both smart drugs and then see what you like best.

I found Modafinil to be strong, but with more side effects, albeit minor ones. Armodafinil is a little less heavy, but maybe better for regular, long-term usage.

There is no real “winner” here.


Because both Modafinil and Armodafinil work damn well.

These are two of the world’s most popular smart drugs for good reason. The cognitive benefits from either will ensure you get more stuff done, make more money, and retain more information.

That’s a guarantee…

That Armodafinil and Modafinil both just work!

HI Jake, thank you for the information and comparisons between the two smart drugs. Very informative information. Just a little confused though, on one hand you say:”I found it MUCH easier to fall asleep after taking Modafinil compared to Armodafinil. With similar timing and dosing, I fell asleep about 2-3 hours early when taking Armodafinil – which was a huge surprise. Nuvigil simply didn’t disrupt my sleep as much as Provigil did.

On the flip side, if you’re trying to stay up all night or work late hours, then Modafinil may be a better choice – as it’s nearly impossible to fall asleep after taking the smart drug.”

So, you found it much easier to fall asleep on Mondafinil…..but “if your’re trying to stay up all night, then Mondafinil may be a better choice”…”as its nearly impossible to fall asleep after taking the smart drug”?

You seem to contradict yourself often throughout the article on a few occasions. I’am just trying to get some clarity. Thanks

Hi Jake, I appreciate the information on both drugs. However, my experience with these drugs has been much different. I have taken Modafinil for several years. When I first started it I had difficulty falling asleep but only for a couple of nights. Now I fall asleep sitting in a chair. I took Nuvigil for a couple of years and actually found it to be much more effective in keeping me awake during the day (with no side effects) but couldn’t stay on it because of insurance coverage. Now that it is generic I’m hoping to be able to go back on it.

    I guess we all react to different products differently.

    Hope you’re able to get back on it if the stuff truly helps you.

    Cheers for the comment.
