Updated on February 27, 2021

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 brand new class of supplement which have exploded onto the market in recent years.

Flyby is one of new brands on the scene designed to boost liver function in order to prevent some of the negative effects of alcohol.

With so many new products emerging each year, we thought it’s a good time to put Flyby to the test.

How does it fare against the top hangover prevention products?

To answer this question, we take a closer look at the company reputation, customer reviews and ingredient list to see whether Flyby can compete against the best.

Flyby – Company background

Flyby is a supplement that claims to be the best natural prevention for hangover symptoms.

This hangover supplement is the brainchild of Eddie Huai, a young entrepreneur who is based in New York.

Eddie came up with the idea of developing Flyby pills after encountering a Japanese drinking supplement that made him wake up ‘feeling great.”

Flyby claims that their hangover remedy is “built on science, not superstition”, and uses high-quality ingredients to formulate his supplement.

According to the manufacturer, Flyby should help:

  •        Prevent some of your hangover symptoms such as nausea, dry mouth, and loss of appetite
  •         Boost your body’s ability to defend against the inflammatory response to alcohol
  •         Effectively metabolize alcohol-induced toxins
  •         Replenish nutrients depleted by alcohol

So, with that in mind, lets take a closer look at the actual ingredient list.

Flyby Hangover Pills 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. Acetaldehyde is a well-known cause of almost all 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.

Flybys ingredients label says that their Silymarin content is standardized to 80% which is great, However, we still that no idea how much of it is in there.

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 proven its effectiveness in easing common hangover symptoms such as headaches, dry mouth, vomiting, and nausea.

Like Milk Thistle and Dihydromyricetin, Prickly Pear is also part of the proprietary blend. This simply means that we are still in the dark regarding its exact amount in this formula.

 Panax Ginseng

 The results of one study performed to assess the effects of Panax Ginseng found an interesting discovery. The extract enhanced blood alcohol clearance in 14 healthy male volunteers.

The results of this study are promising, however its limited by the the tiny size of just 14 subjects so more research needs to be done on this ingredient before its effects are proved.

Acetyl-L-Cysteine (NAC) 

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

Alcohols breakdown produces toxic by-products which cause “oxidative damage”. Antioxidants like glutathione help clear them from the body.


Alcohol is a diuretic which means it increases the loss of water from your kidneys. With this, you’ll also lose electrolytes like magnesium.  We’re happy to see its inclusion in Flybys formula to replenish stores.

So how does Flyby actually work?

So now that we’ve covered the ingredients, we’re in a better position to explain how they work together.

Hangovers are caused dehydration and “free radical damage” from the toxic by-products of alcohol breakdown.

The solution to dehydration is to drink more which is simple enough.

Free radicals are normally cleared by antioxidants which are produced by your liver, or you get them directly from the foods you eat.

This is where hangover supplements come in. They are essentially supercharged antioxidant blends that provide your liver with support to carry out its detoxifying functions.

How do you take Flyby?

The manufacturers advise taking 3 capsules before your first drink and 3 straight after your last.

This is a pretty standard dosing you’ll see in most top hangover supplements and there’s a good reason for it.

It’s essential that the ingredients in these supplements can work before the toxic waste products of alcohol can exert their damage.

Once you’re already hungover, the damage is done and the only real healer is time.

Are There Any Side-Effects with Flyby Hangover Pills?

We haven’t heard any complaints about anyone experiencing some nasty side-effects. It’s probably because they’ve used all-natural ingredients. For this, we applaud Flyby for creating a product that doesn’t use any harmful ingredients.

Flyby supplement reviews

At the time of writing, Flyby has a 4.5 out of 5 rating on Amazon with a total of 1447 reviews.

Overall the reviews are positive with most users having at least some reduction in their hangover symptoms.

Anything else to consider?

When it comes to hangovers, following the simple prevention steps such as drinking plenty of water throughout your night as well as eating a meal before going out is key.

Hangover supplements like Flyby only work as an aid to recovery. They are certainly not magic cure pills.

If you’re planning on getting wasted, Flyby or in fact any hangover supplement just won’t work like you may expect it to.
