It is estimated that the US economy loses $179 billion to hangovers every year because of reduced productivity and taking sick days from work. Hangover prevention pills are a new “class” of supplements that have exploded onto the market as a solution to this problem. 

Flyby Recovery is one of the most popular hangover pills on the market and is designed to boost liver function so that your morning after is less painful. 

With so many new products emerging each year, it’s hard to know which one is actually the best and worth investing in. 

In this review, we’re going to see how Flyby recovery pills compare to the other top products on the market.

Flyby Recovery – Company background

This hangover pill is the brainchild of Eddie Huai, a young entrepreneur who is based in New York. Eddie came up with the idea of developing Flyby recovery after encountering a Japanese drinking supplement that made him wake up “feeling great”.

He brought the ingredient list back to the US and refined it with the help of a PhD scientist to create Flyby recovery pills. The rest is history!

Flyby is easily one of the best-selling hangover pills out there with thousands of positive reviews. They’ve expanded their range way beyond hangover supplements into lifestyle and hydration products as well.

Next up, we’ll take a closer look at the most important factor when it comes to how well a product works – The ingredients formula!

Flyby Recovery Ingredients

If you take a closer look at the ingredients label below, you’ll notice that the ingredients are split. The majority of the ingredient doses are hidden behind a proprietary formula. So we won’t know the exact doses of each ingredient. But nevertheless, we can get a good idea of what flyby recovery contains.

flyby recovery ingredients

Dihydromyricetin (DHM)

Dihydromyricetin (DHM) is a powerful flavonoid that is derived from the oriental raisin tree.

Its been shown by studies to up-regulate the activity of alcohol dehydrogenase (ALDH). This is the enzyme that breaks down acetaldehyde. Aside from dehydration, the damage caused by acetaldehyde is thought to be one of the main causes of hangover symptoms. 

Flyby claims to have extracted DHM via a proprietary method so as to preserve its highest efficacy and purity.

Milk Thistle

Silymarin, the active ingredient in Milk Thistle, is responsible for the herb’s perceived benefits. Studies have shown that it acts as a powerful antioxidant that can reduce liver inflammation.

Milk thistle has been used anecdotally for years to prevent hangovers and many people swear by it.

B-Complex Vitamins (B1, B2, B6, Folic Acid, Pantothenic Acid, and B12)

The B-Complex vitamins replenish your body with vital nutrients depleted by alcohol.  This can help regenerate the enzymes used by your liver to break down alcohol.


Insomnia and anxiety are two nasty symptoms commonly associated with alcohol side effects. L-theanine is extracted from green tea leaves and has been shown to increase brain alpha waves.

These are thought to induce a calming energy on the brain. There isn’t much research with regards to its use in hangovers, however, we can see why Flyby would include this ingredient.

Prickly Pear (Opuntia Ficus)

Prickly Pear or Opuntia Ficus is also part of Flyby’s Hangover cure and prevention formula. Various studies have shown its effectiveness in easing common hangover symptoms such as headaches, dry mouth, vomiting, and nausea.

Panax Ginseng

The results of one study showed that Panax Ginseng potentially enhances blood alcohol clearance. With that said, the study was tiny, with only 14 healthy male volunteers.

The results of this study are promising, but a lot more research needs to be done before its effects are proved.

L-Cysteine (NAC) 

Cysteine boosts the production of Glutathione. Glutathione is known as the bodys “master antioxidant” because it’s the most powerful known.


Alcohol is a diuretic which means it increases the loss of water from your kidneys. With this, you’ll also lose electrolytes like magnesium.  

How do Flyby Recovery pills actually work?

So now that we’ve covered the ingredients, we’re in a better position to explain how they work together. The science of hangovers is complicated, to say the least. It’s definitely not just “dehydration”. 

Hangovers are thought to be caused by a combination of factors that leave you feeling rough after a night out. So far, scientists agree that the following are likely contributors:

  • Inflammation: by-products of alcohol metabolism such as acetaldehyde react with your cells causing inflammation
  • Hormone imbalance: Alcohol wreaks havoc on several hormones including cortisol, insulin and Vasopressin secretion
  • Dehydration: Everyone knows dehydration is a key factor – alcohol blocks vasopressin which leads to water loss from the kidneys.
  • Sleep disturbance: Alcohol massively disrupts sleep quality by preventing the brain from reaching the REM stage which is critical for feeling well-rested.

So, how do hangover pills like Flyby recovery work?

According to the manufacturer, Flyby should help:  

  1. Boost your body’s ability to defend against the inflammatory response to alcohol.
  2. Support the metabolism of alcohol-induced toxins
  3. Replenish nutrients depleted by alcohol

The most important takeaway is that hangover pills are NOT cures. They do not prevent you from getting a hangover and certainly don’t protect against the long-term damaging effects of alcohol.

With that said, they may support recovery and should be seen as an additional aid alongside sensible drinking.

How do you take it?

The manufacturers advise taking 3 capsules before your first drink and 3 straight after your last. This is the standard dosing you’ll see in most top hangover supplements and there’s a good reason for it.

It’s essential that the ingredients get to work before alcohol does its damage. Once you’re already hungover, the damage is done. The only real healer is a takeaway, Netflix, and time!

Also, taking 6 capsules every time you drink may sound like a lot. But you have to bear in mind that there’s only a small amount of space in each capsule. To pack enough of each ingredient for it to have a proper effect is not an easy task.

Is It FDA Approved and Are There Any Side-Effects?

The ingredients in Flyby recovery are all natural with no artificial coloring, additives and medicines. In theory, the side effect profile should be low. 

With that said, everyone is different. You may have unknown intolerances or allergies to some of the herbal extracts and the high dose B vitamins can sometimes give you a bit of reflux.

In terms of FDA approval, supplements don’t require it. Becuase they don’t contain medicines, supplements don’t have to go through trials. However, manufactuers are obliged to meet certain standards to ensure purity and quality.

Flyby revoery is made by a US manufactuerer that adheres to these good manufactuering (GMP) practices.

Flyby recovery pill reviews

At the time of writing, Flyby recoveryhas a 4.3 out of 5 rating on Amazon with over 6000 total reviews! 

That’s more than any other product on the market. The majoirty of people thought that taking made a positive different to how they felt in the morning.

Anything else to consider?

When it comes to hangovers, it’s important to appreciate that prevention is ALWAYS better than “cure”. In fact, a cure doenst exist. 

Ensuring sensible drinking habits is key to preventing the worst hangovers. These include:

  1. Drinking water throughout the night. Ideally between every alcoholic drink to counteract the dehydrating effect of alcohol. You can enhance your hydration efforts by investing in rehydration salts which can support rapid absorption of water.
  2. Eating before drinking alcohol. Having food in your stomach slows down how fast alcohol is absorbed into your bloodstream.
  3. Avoid darker colored drinks (like bourbon and red wine). These contain high amounts of congeners which have been shown to make hangovers a lot worse.

If you’re planning on getting wasted, Flyby recovry pills are not going to help as much as you think. The same applies to every hangover recovery product on the market.

Review conclusion – Final Verdict

Overall, Flyby is a great product. It uses top ingredients that may help reduce the blow from moderate drinking.  It’s one of the most popular products on the market and has a good reputation. 

The only downside is the use of a proprietary blend which means we can’t see exactly how much of each ingredient is used. But overall this is a small thing to dwell on.
