Accurate Supplements – NRF2 Activators

Dietary Supplementation

When considering the need, or at least the potential benefit, of taking a multi-vitamin supplement or other nutritional supplements on a daily or regular basis, one should ask first if they are already maintaining an ideal diet. If the answer is no, then the argument is established that there is at least a potential benefit. The question then becomes what supplements are best to provide nutrients that are most likely to be sub-optimal in your diet.

 

Based on current theories in nutrition, our diets should include plenty of vegetables (especially raw) and fruit. But most people probably do not get optimal amounts of the nutrients associated with these vegetables and fruits. These nutrients include vitamins, minerals, antioxidants and other nutrients. Vitamins and minerals are addressed elsewhere.

 

“Oxidative Stress” and Antioxidants

Current nutritional research supports the belief that many diseases, including diabetes, hypertension, cardiovascular diseases, obesity, liver disease, arthritis and some cancers, are a result of “Oxidative Stress.” Oxidative Stress is an over-abundance of reactive oxygen species (ROS), or “free radicals”, which are destructive molecules that are in our food, our environment and created by our cells during normal metabolic processes. ROS cause oxidation – or damage – to DNA, RNA, proteins and cells analogous to rust damaging steel. To combat these ROS, our cells have protective systems that manufacture antioxidants which neutralize ROS, but as we age there is a gradual impairment of these systems resulting in less antioxidant activity thus greater damage to our DNA, RNA and cells which impairs function and can lead to the above diseases.

 

Ever since Linus Pauling, science has turned to antioxidants to offset the damages of oxidative stress as a means of promoting health. Antioxidant supplements are widely recommended and their use is widespread. Studies have shown that diets high in natural antioxidants (such as the Mediterranean (anti-inflammatory) diet, Okinawan or Paleo diets) seem to provide protection against oxidative stress. Statistics suggest that populations following these diets have less degenerative disease and greater longevity.

 

NRF2 Activators

Recent research has identified certain processes to be very effective at stimulating our body’s natural mechanisms for creating antioxidants through a process called NRF2 activation. NRF2 (nuclear factor erythroid-2-related factor 2) is a transcription factor that activates over 500 genes via molecules called sirtuins. NRF2 activation can be achieved through exercise, calorie restriction (including fasting) and ingestion of natural nutrients that are NRF2 activators. Common NRF2 activators include curcumin (from turmeric spice – probably the best studied and most potent NRF2 activator), along with resveratol (from grapes), quercitin (from onions) and sulphoraphane (from broccoli) followed by antioxidants found in green tea and other soures. Different nutrients may activate NRF2 by different mechanisms and, when taken together, may be synergistic, or more effective when taken separately.

Supplementing with NRF2 activators is believed to offer a number of remarkable health benefits, from reducing inflammation and pain to protection against diabetes (reducing insulin resistance) and protection against a variety of degenerative and immune-based diseases.

 

Bioavailability

Because antioxidants and NRF2 activators are present naturally in many vegetables and fruits, when we eat these foods we reap the benefits.

But do we?

 

The truth is sometimes yes, sometimes no. When we cook plant foods, many antioxidants are destroyed, sometimes as much as 97%. Unfortunately, even when eaten raw the antioxidants in food are often poorly absorbed through the stomach or intestines. Even when they get absorbed into the blood, they often have poor penetration into cells, especially into the brain and nervous system. In many cases the antioxidants we ingest simply do not get to where they can do the most benefit: within the cells. In other words, nutrients in our food are sometimes not very bioavailable (not available to the cells that need them).

 

Nanoformulations

Over the last few years, science has developed new techniques to overcome the problem of bioavailability, including use of nanoformulations. Nanoformulations reduce the size of the nutrient particles down to tiny micron levels and sometimes attach the nutrient to a second component that allows for the particle to be much better absorbed. Studies have demonstrated that nanoforumulations such as “phytosomal curcumin” have improved absorption as much as 29 times more effective.

 

Microsizing and nanoformulations are revolutionizing the pharmaceutical industry by providing the means to allow medications and nutrients that are poorly absorbed to become effectively absorbable and bioavailable. Currently, NRF2 activators that have been nanoformulated include curcumin, quercitin, grape seed extract and green tea extract.

 

Benefits of NRF2 Activators

Recent research has found that “NRF2 activation” is very effective at stimulating our body’s natural protective mechanisms including promoting endogenous (natural)  antioxidant production.

 

Activation of NRF2 is believed to provide many health benefits including:

  1. Reducing systemic inflammation
  2. Lowering of oxidative stress (reducing cellular DNA, RNA and protein damage)
  3. Improving mitochondrial function (cellular energy production)

 

NRFT2 activation may have a positive impact on chronic inflammation and oxidative stress and so may be useful in the prevention or treatment of many common chronic disease processes including obesity and high blood pressure and reducing the risk of diabetes, cardiovascular disease and stroke. NRF2 activators have been shown to protect the liver in conditions of chronic hepatitis and fatty liver.

 

NRFT2 activation and Pain

NRF2 activation is thought to reduce pain related to many conditions. The muscle pain and  fatigue associated with  fibromyalgia is believed to respond to NRF2 activation. NRFT2 activation may reduce the central sensitivity associated with many chronic pain conditions including chronic headaches, chronic back pain, fibromyalgia and interstitial cystitis. There is evidence that NRFT2 activation may reduce the development of opioid tolerance and opioid-induced hyperalgesia (increased pain thought to possibly arise from the use of opioids).

 

NRFT2 activation and Obesity

Obesity, once thought to simply be an overabundance of stored fat is now understood to reflect a much more serious condition characterized by increased systemic inflammation and oxidative stress. As a consequence, obesity is clearly understood to be a major contributor to the development of hypertension, heart disease, stroke and some cancers. Evidence is mounting that NRFT2 activation helps protect against these conditions.

 

NRFT2 Activation and Addiction

Many of the brain’s neurotransmitters and neurochemical processes are impaired in conditions of chemical and behavioral addiction. NRT2 activation may play a role in facilitating restoration of these neurochemical processes and facilitate addiction recovery.

 

How is NRF2 activation achieved?

NRF2 activation can be achieved through:

  1. Exercise
  2. Calorie restriction (including fasting)
  3. Ingestion of natural nutrients and certain antioxidants that are NRF2 activators

 

Common NRF2 activators include curcumin (from turmeric spice – probably the best studied and most potent NRF2 activator), along with resveratrol (from grapes), quercetin (from onions), sulphoraphane (from broccoli) as well as many antioxidants found in green tea and other soures such as raspberries, pomegranates and dark chocolate.  Many of the beneficial effects of antioxidants are actually produced through the NRF2 regulatory response, rather than exclusively through direct antioxidant chemistry as previously believed.

 

Different nutrients may activate NRF2 by different mechanisms and when taken together may be synergistic, or more effective when taken together than when taken separately. NRF2 activators are also found in vegetables including brussel sprouts and garlic, and fruits such as blackberries, raspberries and pomegranates as well as red wine and dark chocolate.

 

Supplementing with NRF2 activators is believed to offer a number of potential health benefits, from reducing inflammation and pain to protection against diabetes (reducing insulin resistance) and protection against a variety of degenerative and immune-based diseases.

Vegetables in a capsule

 

The following is a list of common NRF2 activators:

  1. Curcumin (found in turmeric)
  2. Resveratrol  (found in grape skins and red wine)
  3. Pterostilbene (found in blueberries, cranberries and grapes)
  4. Silybin (found in milk thistle)
  5. Sulforphane (found in brocolli, brussels sprouts, cabbage, cauliflower, bok choy, kale, collards, and mustard)
  6. Alpha Lipoic Acid (found in red meat, organ meats (i.e. liver), and yeast, particularly brewer’s yeast)
  7. Vitamin D (found in egg yolks, saltwater fish, liver. and dairy products like milk)
 
Unfortunately, due to cooking, poor intestinal absorption and other factors, ingesting these foods may not allow adequate systemic absorption to provide the desired benefits from these nutrients. To overcome this problem of bioavailability, special “nanoformulations’ have been developed (see references below) that allow for much greater absorption and availability. 
 
 

Nanoformulations of NRF2 Activators:

  1. PolyResveratrol (a mixture of 6 NRF2 activators)
  2. Meriva (curcumin phytosome)
  3. Siliphos (silybin phytosome)
 
 
Additional nutrients that may offer synergistic benefits to NRF2 activators:
 

Nicotinamide Riboside – NR

Nicotinamide riboside (NR) is a recently discovered nutrient found in milk. It is a niacin-like nutrient (Vitamin B-3) that is a precursor to NAD, a molecule necessary for providing energy for the vital  intracellular pathways involved with NRF2 activation. Supplementing with NR may provide a synergistic benefit to use of NRF2 activators. NR is available as Niacel. (see NR)
 
 

Palmitoylethanolamide (PEA)

Palmitoylethanolamide (PEA), an endogenous fatty acid amide, is emerging as a novel agent in the treatment of pain and inflammation. Human studies demonstrate PEA benefits to include peripheral neuropathies such as diabetic neuropathy, chemotherapy-induced peripheral neuropathy, carpal tunnel syndrome, sciatic pain, osteoarthritis, low-back pain, failed back surgery syndrome, dental pain, central neuropathic pain in stroke and multiple sclerosis, chronic pelvic pain, postherpetic neuralgia, and rectal and vaginal pains. (see PEA)
