The NORI PROTOCOL

A Simple Approach Combining Diet and Select Nutraceuticals

There are two core elements of the NORI protocol which are a methionine restricted diet and the creation of oxidative stress. A methionine restricted diet is intended to slow cancer progression and weaken cancer cells. Oxidative stress is a powerful mechanism to trigger apoptosis selectively in cancer cells. This idea is contrary to the belief that antioxidants are beneficial for cancer treatment. Current studies show that antioxidants help the survival of cancer cells.


Diet is a powerful tool but diet alone is not sufficient in treating cancer. This is because there are many uncontrolled tumor growth factors and diet alone can not overcome these powerful tumor growth signals. One example is estrogen which must be appropriately addressed in ER+ breast cancers.


The NORI protocol is not based on building or boosting the immune system. It is not based on correcting nutritional deficiencies so it utilizes very minimal nutritional supplementation. Certain nutritional supplements are known to promote tumor growth so these are excluded from the protocol.

About Methionine and Cancer

Watch Dr. Michael Greger explain how methionine is critical to cancer cell growth. Methionine restriction is both a safe and practical dietary intervention if applied with proper supervision. NORI recommends that one enroll in our support program to implement methionine restriction safely and effectively.

How not to die from cancer

This video by Dr. Michael Greger shows how a plant-based diet is best for cancer prevention and can be a powerful tool in cancer treatment. IGF-1 is a major factor in cancer progression but there is much more that a plant-based diet can offer in slowing or reversing tumor growth.

Important information on the ketogenic diet for Cancer

In this video, Dr. Michael explains why the ketogenic diet approach is not appropriate for cancer treatment. A ketogenic diet is highly promoted currently for cancer treatment but the experience of NORI is that it is counterproductive and has resulted in rapid tumor progression.

Diabetes and Insulin resistance (It's the Fat)

In this video, Dr. Michael Greger explains the root cause of type II diabetes (Insulin Resistance). This is important to understand why a high fruit diet does not spike insulin and blood glucose. Keep in mind that insulin is a significant tumor growth promoter.

Anti-angiogenesis

Dr. Michael Greger explains how a plant-based diet is beneficial in suppressing angiogenesis which is crucial in preventing cancer and treating cancer.

The Science

Methionine Restriction for Cancer Therapy

Methionine restriction is a powerful dietary approach that attempts to starve cancer cells of an essential amino acid building block necessary for protein synthesis. Methionine restriction has other applications in extending lifespan, improving metabolic health and lowering inflammation. Of all the different dietary approaches to cancer, methionine restriction stands out as the approach most supported by scientific research. Methionine restriction not only limits the availability of one particular amino acid necessary for cancer cell growth and survival, but also limits other critical amino acids that cancer cells require for growth and division. Normal cells are unharmed through these intermittent nutritional interventions. NORI has developed a specific methionine restriction protocol that has been utilized for many years with proven success. It is recommended that one consults with NORI in applying a methionine restricted diet for best results. We offer low-cost programs to support you.


NORI has compiled many scientific papers on methionine restriction as a therapeutic tool in cancer therapy. Click here to download these studies that we have carefully reviewed and utilized in designing our methionine restriction protocol.

Sodium Selenite

Inorganic Selenium

Over 40 years of research has demonstrated that sodium selenite is a powerful selective chemotherapeutic agent. Click here to review the scientific studies on sodium selenite as an anti-tumor agent. Because sodium selenite is a non-patentable molecule, an insignificant amount of investment into clinical research has been available. Sodium selenite is very inexpensive readily available as a nutritional supplement. For cancer prevention, supplementation with sodium selenite at 200-400 micrograms per day is appropriate. For therapeutic purposes, the dose for sodium selenite ranges from 6,000-30,000 micrograms per day. Sodium selenite is a  small water soluble molecule so it has excellent bioavailability. It also has a sufficiently long plasma half-life to allow an excellent therapeutic response. Sodium selenite can be administered by IV injection or administered as a sublingual tablet. Do not self-administer sodium selenite as it can be toxic at excessive dosages and will cause severe nausea if if not taken properly. NORI can assist you with proper IV administration by working with your physician or through our support program.

The Science

Selenium for the Prevention and Treatment of Cancer

Selenium is possibly one of the most studied nutritional factors associated with cancer prevention. Because of the data collected on the importance of adequate selenium for cancer prevention, numerous studies have looked at various forms of selenium for cancer treatment. Sodium selenite appears to be one of the most effective forms of selenium for cancer therapy.  There is some concern regarding the toxic nature of selenium compounds but at the dosages required for cancer treatment, there is no potential toxicity. Excessive selenium intake can cause reversible hair loss and changes to the nails. There are ongoing clinical trials at the Karolinska Institute in Sweden to evaluate the safety and effectiveness of sodium selenite as a chemotherapeutic agent. When sodium selenite is combined with other pro-oxidants such as vitamin K3 and genipin, the response is enhanced through a synergistic mechanism creating a higher level of oxidative stress.

Lithium Chloride

Lithium for the Prevention and Treatment of Cancer

NORI is currently investigating the potential of lithium in the treatment of cancer. Lithium is a naturally occurring alkali metal commonly found in foods and is associated with a significantly reduced cancer risk. Various forms of lithium have been prescribed for decades as a treatment for bipolar disorder. Studies have identified pathways in cancer cells that are affected by lithium treatment which lead to apoptosis. One identified pathway is called GSK-3ß which lithium inhibits and leads to elevated ROS triggering apoptosis.


Lithium chloride is a highly water soluble salt that was once sold as a salt substitute. Lithium chloride can be toxic at high levels and prolonged exposure. However, for intermittent pulsed treatment, lithium chloride may prove to be safe and effective.  As an anti-cancer agent, lithium chloride is not likely to be effective alone but highly effective in combination with other anti-cancer agents. An in vivo study showed that lithium chloride acted synergistically with 5-FU resulting in highly significant survival.
