The more alcohol you drink, the more likely it is you will experience symptoms. 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 from acetaldehyde. 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.
