Here's what they don't want you to know about ni****ne:
A pro-metabolic, anti-inflammatory, performance-enhancing, dopaminergic, neuroprotective POWERHOUSE πͺ
We'll look at how ni****ne can be protective against a variety of health conditions including:
- Parkinson's disease
- Dementia
- Inflammatory bowel diseases
- Depression
- Schizophrenia
- COVID/mortality due to other viral infection
Ni****ne is an alkaloid derived from to***co
After entry into the blood, it is broken down into several different metabolites...
The primary bioactive metabolite is called cotinine, although others are currently being studied
Acetylcholine:
In the brain, ni****ne essentially "mimics" the neurotransmitter acetylcholine (ACh)
It does this through binding with 7-a-nicotinic acetylcholine receptors
Ni****ne also upregulates these receptors
Recent evidence suggest ni****ne may also inhibit acetylcholinesterase, the enzyme responsible for breaking down ACh, in the brain.
The result is increased cholinergic neurotransmission in the nervous system, which is thought to be one of the ways by which ni****ne enhances memory and learning.
This has downstream effects on numerous other neurotransmitter systems including:
- Dopamine
- Serotonin
- Glutamate
- GABA
Abundant evidence suggests a cholinergic deficit in the CNS is one of the drivers of MCI/Alzheimer's (AD)
One study found subcutaneous ni****ne to improve:
"primary and secondary cognitive measures of attention, memory, and mental processing"
Another study found inverse association between AD and smoking:
"A statistically significant inverse association between smoking and Alzheimer's disease was observed at all levels of analysis, with a trend towards decreasing risk with increasing consumption"
Cognitive benefits:
"1. Ni****ne improves attention in a wide variety of tasks in healthy volunteers.
2. Ni****ne improves immediate and longer term memory in healthy volunteers.
3. Ni****ne improves attention in patients with probable Alzheimer's Disease.
4. While some of the memory effects of ni****ne may be due to enhanced attention, others seem to be the result of improved consolidation as shown by post-trial dosing."
Ni****ne: An Anti-inflammatory Molecule
The ni****ne : acetylcholine interaction extends beyond cognitive benefits
Acetycholine is one of the primary tools used by the body to suppress inflammation and immune-hyperactivation
In this way, it can βswitch offβ an overactive immune system
It does this through a network of neuronal connections known as the "cholinergic anti-inflammatory pathway", which operates through the vagus nerve
Stimulating this pathway via different means has yielded promising results in a variety of chronic inflammatory diseases
"Ni****ne stimulation plays a key role in suppressing inflammatory cytokine production
- Can significantly down-regulate and delay inflammatory and autoimmune responses in the central nervous system
- Could further attenuate neuro-inflammation"
Anti-inflammatory effects pt.2
The following paper discusses anti-inflammatory and pro-inflammatory effects of ni****ne at length.
Read it and you will see the "anti" far outweighs the "pro"
"Of all the diseases summarized here concerning systemic inflammation, especially in sepsis and endotoxemia, ni****ne exerted the most pharmaceutical effect and significantly improved the survival.
Next, ni****ne is also a potential candidate for treating ulcerative colitis, rheumatoid arthritis, osteoarthritis, multiple sclerosis, and myocarditis;"
Protection against endotoxin:
"In this model of abbreviated inflammation, ni****ne exposure attenuates the febrile response to LPS and promotes a more prominent anti-inflammatory phenotype."
Ni****ne stimulates the release of dopamine in the midbrain and prefrontal cortex
Protects dopaminergic neurons from degeneration.
This protection extends to Parkinsonβs disease.
Smokers are vastly less likely to develop Parkinsonβs.
Even exposure to secondhand smoke drastically reduces the chances.
βThe link between smoking and a lower risk of Parkinson's disease (PD) is one of the strongest environmental or lifestyle associations in neuroepidemiology. Growing evidence supports the hypothesis that the association is based on a neuroprotective effect of smoking on PDβ
Neuroprotection / anti-excitotoxic:
Ni****ne exerts neuroprotective effects through reducing glutamate excitotoxicity in several regions of the brain, including the hippocampus.
This may help to explain positive neuropsychiatric benefits in conditions such as schizophrenia, bipolar disorder, ADHD and anxiety
Neurogenesis, NAD+ and Anti-Aging:
βF-FDG PET imaging revealed that ni****ne is also capable of efficiently inhibiting glucose hypermetabolism in aging male mice.
Additionally, ni****ne ameliorated cellular energy metabolism disorders and deferred age-related deterioration and cognitive decline by stimulating neurogenesis, inhibiting neuroinflammation, and protecting organs from oxidative stress and telomere shortening.
Collectively, these findings provide evidence for a mechanism by which low-dose ni****ne can activate NAD+ salvage pathways and improve age-related symptoms.β
Metabolism/Thyroid:
Ni****ne is well known to increase resting metabolic rate.
Ni****ne was shown to activate thyroid hormone receptor-B in the brain, and might βsubstituteβ for thyroid hormone to some extent.
Ni****ne stimulates the conversion of T4 to active thyroid hormone, T3, through increasing activity of deiodinase 2.
βni****ne reversed/ameliorated hypothyroidism-induced deficits in learning and memory at the molecular, cellular, and behavioral level.β
When smokers quit, the deficits in learning/cognition/memory could be alleviated by thyroid hormone supplementation.
Smoking and the thyroid:
Smokers on average have higher T3 levels, lower TSH and lower markers of thyroid autoimmunity.
Smokers have a significantly lower risk of developing hypothyroidism and autoimmune thyroid disease. This protection disappears 3 years after quitting smoking.
COVID & dysautonomia:
The fix for long-COVID (or vaccine-induced) Dysautonomia?
For many, its NI****NE
Why? Top-down control of the autonomic nervous system depends on cholinergic neurotransmission, involving the neurotransmitter acetylcholine.
Researchers found evidence of an interaction between SARS-CoV-2 spike protein & nicotinic-acetylcholine receptors (nAChRs), and hypothesize that this may impair the cholinergic system.
When the body loses control of acetylcholine, it loses control of the autonomic nervous system = dysautonomia.
Ni****ne binds with nAChRs and potentiates the action of acetylcholine.
Ni****ne UPREGULATES nAChRs. It is hypotethized that ni****ne may "counteract the viral blockade of nAChRs" and restore cholinergic activity.
It was known in the early days that smokers had much higher protection against infection, and it was thought this was related to the ACE2 receptor.
However, many are using it post-covid and even post-vaccination to re-establish autonomic balance.
A lot of people already know HIGH DOSE THIAMINE can be effective for long-covid/post-covid vaccine effects.
What many don't know is that thiamine is necessary for the release and action of acetylcholine at every step!!
The combination of thiamine + ni****ne could be a game changer.
Ni****ne can be used in gum, patches, or of course... combusted.
Vaporization would be my personal choice of entry
Ni****ne = Anti-estrogenic
Low dose of ni****ne inhibits aromatase, the enzyme which catalyses the conversion of androgen hormones into estrogen
This has been shown to occur in numerous regions of the brain
In animals: "In laboratory studies on female rats, we confirmed the aforementioned epidemiological findings that chronic ni****ne exposure reduced endogenous 17Ξ²-estradiol (E2; a potent estrogen) levels"
