What is Alcohol Flush Reaction?

Alcohol Flush Reaction is the simplest way a person can tell if he or she has ALDH2 Deficiency. Alcohol Flush Reaction is a series of negative physical symptoms that occur when drinking alcohol. In addition to intense red flushing of the face and skin, other symptoms include headache, overheating, dizziness, nausea, increased heart rate, and increased hangover. These symptoms are all a sign that something isn't right inside the body.

When alcohol is consumed, it is broken down into acetaldehyde, a toxic compound that is the cause of many of the negative effects of drinking alcohol. Those with ALDH2 Deficiency cannot break down acetaldehyde properly, and so it accumulates wildly in the body, causing the symptoms of Alcohol Flush Reaction. What's really happening is acetaldehyde is causing damage to DNA and proteins in the body, and causing inflammation in the skin, which leads to redness. 

Is it the same as Asian Flush or Asian Glow?

Alcohol Flush Reaction is commonly referred to as 'Asian Flush' or 'Asian Glow'. All of these names refer to the same reaction. It is often called this because ALDH2 Deficiency is most commonly found in people of East Asian descent, including Chinese, Japanese, Korean, Vietnamese, Filipino, and more.

Some people may be concerned or embarrassed about his or her face turning red when drinking, which is a natural response. However those who experience Alcohol Flush Reaction should also be concerned about the negative health implications ALDH2 Deficiency and exposure to acetaldehyde as Alcohol Flush Reaction is the sign of a larger issue. Those with ALDH2 Deficiency should practice moderation when consuming alcoholic beverages.

How does Essential AD2 help?

Essential AD2 is clinically proven to reduce acetaldehyde, the cause of Alcohol Flush Reaction, and also reduce the facial flushing that occurs when drinking. While Essential AD2 will fight acetaldehyde when taken as a single dose 45 minutes before drinking, for maximum benefit, Essential AD2 should be taken daily for at least 2 weeks. Why? Acetaldehyde levels in those experiencing Alcohol Flush Reaction are very high, and it takes time to create a build up of the beneficial compounds in Essential AD2 to have the most impact. In addition, Essential AD2 protects those with ALDH2 Deficiency from daily exposure to other sources of acetaldehyde. To learn more about these, visit Sources of Acetaldehyde. 

Will Essential AD2 get rid of Alcohol Flush Reaction completely? 

Essential AD2 is clinically proven to significantly reduce Alcohol Flush Reaction and acetaldehyde. However, it may not get rid of it completely. Everyone is different. If you are going to casually drink 2-3 drinks, Essential AD2 is a great option, and will help the redness. Some will experience 'pinkness', but it should be a noticeable reduction. Other symptoms like increased heart rate, overheating, or nausea may also be significantly reduced. This is also a sign that Essential AD2 is protecting from the damage occurring in the body.

Those who binge drink, or drink many alcoholic beverages in a short period of time, may still experience the symptoms of Alcohol Flush Reaction, as very high amounts of acetaldehyde are entering the body at once. It is strongly recommended that those with ALDH2 Deficiency not binge drink, as there is nothing that can protect from very high levels of the acetaldehyde toxin.

In addition, it is important to note that while Essential AD2 will reduce the symptoms of Alcohol Flush Reaction, it will protect those with ALDH2 Deficiency from acetaldehyde regardless of how frequently he or she consumes alcohol. There are many other sources of acetaldehyde, and it is constantly circulating in the body at low concentrations. In fact, acetaldehyde is actually produced inside the body as well.
