Many current research studies on cancer have allowed health professionals to understand the way the body detoxes. By analyzing upregulated genes in tumorous cells, researchers discovered the nuclear erythroid 2-related factor 2 signaling pathway, best known as Nrf2. NRF2 is an important transcription factor which activates the human body’s protective antioxidant mechanisms in order to regulate oxidation from both external and internal factors to prevent increased levels of oxidative stress.
Principles of Nrf2
NRF2 is essential towards maintaining overall health and wellness because it serves the primary purpose of regulating how we manage everything we’re exposed to on a daily basis and not become sick. NRF2 activation plays a role in the phase II detoxification system. Phase II detoxification takes lipophilic, or fat soluble, free radicals and converts them into hydrophilic, or water soluble, substances for excretion while inactivating exceptionally reactive metabolites and chemicals as a consequence of phase I.
NRF2 activation reduces overall oxidation and inflammation of the human body through a hormetic effect. To trigger NRF2, an inflammatory reaction due to oxidation must occur in order for the cells to produce an adaptive response and create antioxidants, such as glutathione. To break down the principle of Nrf2, essentially, oxidative stress activates NRF2 which then activates an antioxidant response in the human body. NRF2 functions to balance redox signaling, or the equilibrium of oxidant and antioxidant levels in the cell.
A great illustration of how this process functions can be demonstrated with exercise. Through every workout, the muscle adapts so that it can accommodate another workout session. If NRF2 becomes under- or over-expressed due to chronic infections or increased exposure to toxins, which may be observed in patients who have chronic inflammatory response syndrome, or CIRS, the health issues may worsen following NRF2 activation. Above all, if DJ-1 becomes over-oxidized, NRF2 activation will end too quickly.
Effects of NRF2 Activation
NRF2 activation is highly expressed in the lungs, liver, and kidneys. Nuclear erythroid 2-related factor 2, or NRF2, most commonly functions by counteracting increased levels of oxidation in the human body which can lead to oxidative stress. Nrf2 activation can help treat a variety of health issues, however, over-activation of Nrf2 may worsen various problems, which are demonstrated below.
Periodic activation of Nrf2 can help:
Aging (ie Longevity)
Autoimmunity and Overall Inflammation (ie Arthritis, Autism)
Cancer and Chemoprotection (ie EMF Exposure)
Depression and Anxiety (ie PTSD)
Drug Exposure (Alcohol, NSAIDs )
Exercise and Endurance Performance
Gut Disease (ie SIBO, Dysbiosis, Ulcerative Colitis)
Cancer (ie Brain, Breast, Head, Neck Pancreatic, Prostate, Liver, Thyroid)
Chronic Inflammatory Response Syndrome (CIRS)
Heart Transplant (while open NRF2 may be bad, NRF2 can help with repair)
Nephritis (severe cases)
Furthermore, NRF2 can help make specific nutritional supplements, drugs, and medications work. Many natural supplements can also help trigger NRF2. Through current research studies, researchers have demonstrated that a large number of compounds which were once believed to be antioxidants were really pro-oxidants. That’s because nearly all of them need NRF2 to function, even supplements like curcumin and fish oil. Cocoa, for example, was shown to generate antioxidant effects in mice which possess the NRF2 gene.
Ways To Activate NRF2
In the case of neurodegenerative diseases like Alzheimer’s disease, Parkinson’s disease, stroke or even autoimmune diseases, it’s probably best to have Nrf2 upregulated, but in a hormetic fashion. Mixing NRF2 activators may also have an additive or synergistic effect, as occasionally it can be dose-dependent. The top ways to increase Nrf2 expression are listed below:
HIST (Exercise) + CoQ10 + Sun (these synergize very well)
Broccoli Sprouts + LLLT on my head and gut
Butyrate + Super Coffee + Morning Sun
Acupuncture (this is an alternative method, laser acupuncture may also be used)
Lion’s Mane + Melatonin
Alpha-lipoic acid + DIM
The following comprehensive listing containing over 350 other ways to activate Nrf2 through diet, lifestyle and devices, probiotics, supplements, herbs and oils, hormones and neurotransmitters, drugs/medications and chemicals, pathways/transcription factors, as well as other ways, is only a brief guide as to what can trigger Nrf2. For the sake of brevity in this article, we have left out over 500 other foods, nutritional supplements and compounds which can help activate Nrf2. The following are listed below:

The nuclear erythroid 2-related factor 2 signaling pathway, best known by the acronym Nrf2, is a transcription factor which plays the major role of regulating the protective antioxidant mechanisms of the human body, particularly in order to control oxidative stress. While increased levels of oxidative stress can activate Nrf2, its effects are tremendously enhanced through the presence of specific compounds. Certain foods and supplements help activate Nrf2 in the human body, including the isothiocyanate sulforaphane from broccoli sprouts. Dr. Alex Jimenez D.C., C.C.S.T. Insight

Additional Topic Discussion: Acute Back Pain
Back pain is one of the most prevalent causes of disability and missed days at work worldwide. Back pain attributes to the second most common reason for doctor office visits, outnumbered only by upper-respiratory infections. Approximately 80 percent of the population will experience back pain at least once throughout their life. The spine is a complex structure made up of bones, joints, ligaments, and muscles, among other soft tissues. Injuries and/or aggravated conditions, such as herniated discs, can eventually lead to symptoms of back pain. Sports injuries or automobile accident injuries are often the most frequent cause of back pain, however, sometimes the simplest of movements can have painful results. Fortunately, alternative treatment options, such as chiropractic care, can help ease back pain through the use of spinal adjustments and manual manipulations, ultimately improving pain relief.
