N-acetylcysteine is an amino acid, that possesses the ability to stabilize and cross the blood brain barrier (BBB)[1] .  Once inside the brain it is a precursor (building block) to glutathione (GSH) which is the brain’s most potent and primary antioxidant.  These properties enable it to protect the brain from injury and aid in its recovery from injury and insult. 


Injury to the brain from a vaccine can be due to several factors such as: 

- disruption of the blood brain barrier (the blood brain barrier is what protects the brain from unwanted products in the blood system);

- direct insult to the brain from various additives such as alum;

- inflammatory response to the viral or bacterial particles or;

- a hypersensitized immune system. 

In any of these scenarios, the result is the same, an inflamed brain.  Inflammation of the brain, be it permanent or temporary, will inherently result in brain dysfunction. 


Of all the factors that can irritate the brain, the most controversial one is aluminum.  Alum is a form of aluminum that is used as an adjuvant.  Adjuvants are used to make vaccines more effective.  In fact, some vaccines would not work at all were it not for the adjuvants.  Here is where major concerns lay.  According to a study in Frontiers in Psychiatry, “Aluminum, as a known neurotoxicant, contributes to cognitive dysfunction and may contribute to Alzheimer’s disease. The important reason is that aluminum can enter and be deposited in the brain.”[1]  Once in the brain, it and other additives, including the virus being injected, can cause inflammation of the brain. Once inflamed, brain dysfunction can occur.  Brain dysfunction can come in the form of OCD, anxiety, depression, ASD, ADHD, bipolar disorder, tics and mood instability, to name a few[2].  

Fortunately, N-acetylcysteine (NAC) has the unique ability to detoxify the brain when the BBB has been crossed.  By increasing the production of glutathione, NAC reduces the inflammation and aids in the recovery of the brain from the toxic insults that may result from a vaccine. 


To make matters even better, NAC is safe in children and adults and the only real side effects are nausea and vomiting that occur when it is taken in too high a dose at too high a concentration[3].
