N-Acetylcysteine is a mental health marvel. From anxiety, to ADHD, autism and even suicidal depression, it acts as a master mood stabilizer. Let's talk about the benefits of NAC, the science and how to use it yourself:
N-Acetylcysteine cuts OCD in half.Titrated up to 2.4g per day (as add on treatment). NAC works here by reducing glutamate release from neurons. This glutamate is responsible for "excitatory" brain processes, which in excess can contribute to OCD.
N-Acetylcysteine cuts depression by >60%, anxiety by 50%.1.2 g per day. Excess glutamate in distinct brain regions can contribute to these feelings. NAC's ability to lower it in the ventrolateral prefrontal cortex contributes to its antidepressant and anti-anxiety effects.
N-Acetylcysteine rapidly reverses suicidal depression.Within days, it dramatically reduced: ⇨ Depressive symptoms ⇨ Suicidal thoughts This likely has to do with NAC's: ⇨ Dopamine balancing ⇨ Glutamate balancing ⇨ Antioxidant ⇨ Anti-inflammatory properties
N-Acetylcysteine treats autism.900 mg 2x per day significantly improves multiple symptoms of autism within a few weeks. ASDs are commonly characterized by: ➜ Brain oxidative stress ➜ Neuroinflammation ➜ Excess glutamate excitation
N-Acetylcysteine rapidly corrects ADHD.Within 3 doses of 2.4g, improvement was seen. ADHD is also characterized by: ➮ Mitochondrial dysfunction ➮ Dopamine dysfunction ➮ Glutamate excess ➮ Lowered brain volume ➮ Neuroinflammation all things NAC can favorably impact.
NAC stimulates brain growth.It was shown to restore the levels of: □ BDNF - neurogenesis, brain cell survival, growth □ Acetylcholine - neurotransmitter involved in attention, memory in response to stressors.
NAC improves memory, mitochondrial function.Energy production declines with age, leading to: ◇ Brain cell death, volume loss ◇ Impaired neurotransmitter production ◇ Worsened cognition NAC restores the activity of mitochondrial enzymes, improving memory in the process.
N-Acetylcysteine improves addiction.People were surveyed, and they voted that they were less willing to blow their money on cocaine when treated with NAC. Addiction is often accompanied by dysregulated glutamate and dopamine functioning. NAC helps.
PTSD improved with N-acetylcysteine.PTSD is a debilitating condition that often results in low dopamine and low glutamate. NAC is unique in that it can balance both of these key neurotransmitters. There's also a component of oxidative stress, which NAC helps to combat.
Aluminum decimates brain function - N-acetylcysteine restores it.Aluminum is a common additive in foods and drugs, and can contribute to oxidative damage in the brain, leading to Alzheimer's and cognitive decline. NAC protects against this by rapidly elevating glutathione. \[\[Heavy metals change your personality and behavior\]\]
N-Acetylcysteine works in a few different ways. Unlike most drugs or nootropics, NAC tends to raise or lower various neurotransmitters based on the circumstance. Primarily, glutamate and dopamine. In situations where one of these neurotransmitters is lacking, NAC can elevate levels. If in excess, NAC can lower levels. Hence, NAC can act as a master "stabilizing" agent. NAC also serves as an efficient precursor to our master antioxidant, glutathione, which serves a vital role in structurally protecting the brain. Part of that role is to protect the mitochondria, which can become damaged and cease energy production without sufficient glutathione. This also gives it a powerful anti-inflammatory effect. All of these processes are common in psychiatric and cognitive disorders - what defines them is to what extent and in what brain regions / scenarios they happen.
DOSING / USING NAC: ◇ As shown above, typical doses range from 600-2400 mg. ◇ I would start even less than that if you are interested, and titrate up depending on how you feel. ◇ NAC has the potential to cause GI side effects (though it also is used to treat inflammatory gut conditions) ◇ Its highly stabilizing properties on glutamate and dopamine can contribute to a lack of excitement in general, if you run high on these. In general, it's very safe.
