N-Acetylcysteine (NAC) is potent anti-aging medicine. It extends lifespan, lowers inflammation, improves metabolism and even sexual function. Let's cover the numerous benefits, the science and how you can implement it:
N-Acetylcysteine + glycine increases lifespan by \~25%As precursors to the master antioxidant glutathione, this combination: ✓ Reduces organ damage ✓ Preserves mitochondrial function even at low amounts.
N-Acetylcysteine relieves asthma.Asthma is largely driven by glutathione depletion, but NAC: ⁂ Reduces inflammation: TNF-α, IL-5, IgE, eosinophils, nitric oxide ⁂ Improves antioxidant status ⁂ Normalizes lung pathology + symptoms
NAC + glycine is an anti-aging, metabolic elixir.➜ Reduces oxidative stress ➜ Improves mitochondrial function ➜ Improves cognitive function ➜ Reverses insulin resistance Nearly every metric of aging and disease imaginable.
NAC induces remission of inflammatory bowel disease.Another condition of oxidative damage and inflammation, adding NAC for UC: ➜ 4X'ed remission rates ➜ Improves symptoms and reduced inflammatory markers: ➜ ESR ➜ IL-1β ➜ IL-8 ➜ MPO ➜ CRP ➜ ESR ➜ Calprotectin
NAC drastically reduces gut inflammation.Another study confirmed that it: ◇ Improves clinical score ◇ Lowers IL-8 ◇ Lowers MCP-1 ◇ Lowers IL-6 in people with UC, when used in combination with standard therapy.
NAC enhances dopamine.Treatment was shown to support growth of dopamine producing cells in the brain. This coincided with improved symptoms from low dopamine.
NAC boosts testosterone, dramatically improves male fertility. Poor sexual function and fertility is actually an oxidative stress driven process, and NAC: ◇ Increases testosterone ◇ Normalizes pituitary hormones ◇ Improves sperm motility ◇ Increases sperm volume
NAC can reverse fatty liver disease.The liver is probably the most important organ that never gets talked about, and NAC keeps it healthy by: ➞ Shedding liver fat ➞ Reducing liver damage ➞ Improving insulin resistance ➞ Lowering inflammation
NAC is a powerful way to improve immune function.A study showed that HIV patients were 2X more likely to survive when incorporating NAC. The immune system depends heavily on proper antioxidant support. Here, NAC regenerated their T cells.
NAC is therapeutic in autoimmune disease.In autoimmune disease, the immune system's T cells are skewed towards an inflammatory type, but NAC: ➞ Improves symptoms ➞ Restores glutathione ➞ Enhances mitochondrial function resulting in improved disease progression.
Aluminum drives Alzheimer's disease - NAC prevents it.Aluminum is highly present in many foods / drugs / consumer products, and can be a neurotoxin by inducing oxidative damage in the brain. NAC: ➞ Improves memory ➞ Restores antioxidant status ➞ Normalizes brain structure \[\[Heavy metals change your personality and behavior\]\]
HOW NAC WORKS:Glutathione is the body's "master" antioxidant, which is vital for protecting against free radicals. Glutathione also acts as a detoxifying agent - it binds to various environmental toxins and aids in their excretion. Excess free radicals directly drive inflammation and insulin resistance, and slow down mitochondrial energy output - among other key processes. It is due to these actions that NAC has such a broad spectrum of benefit - many age related and metabolic conditions are inflammatory and oxidative stress driven in nature.
