How much vitamin B17 (amygdalin) can I take?

With cancer: It is most important to eat the kernels and everything else comes after. (Not counting prayer and understanding, which come first). The kernels should be chewed well. A few per hour is what should be ingested when you have cancer. The best results have come when the person eats 3-5 per waking hour. Alternatively they can be ground up and mixed with fruit juice or food, to make sure they get into the system. Some people find eating the kernels cures constipation! If this creates a problem the other way - this usually settles down soon.

Vitamin B17 tablets (amygdalin, laetrile, nitriloside) are water soluble and non-toxic. They are safer than sugar or salt. (However, you can get stomach cramps when you take too much - you must test and see just what your body needs.) Some people get nauseous if they take too much at one time. (This is also common when taking too much sugar, salt or water at one time.) If this is the case, take less amount of the vitamin tablets more often throughout the day. If you presently have cancer, you can have six to ten of the five hundred milligram tablets per day for the first month. (Taking two at a time is fine.) Most individuals with cancer only take 3 - 6 tablets per day. If you find that you are getting nauseous, cut the tablets in half and have one every other hour. It is a good idea to have a little food (but not raw fruit/vegetables) in the stomach just before taking the vitamin. From on 17.05.00. This website also emphasises that it is a good idea to have some food in the stomach when taking high doses of B17. (However, Binzel suggests taking the tablets on an empty stomach, so it is best to experiment. Personally we have found having food in the stomach best - but not raw fruit or vegetables. So bread, biscuits, cooked fruit or vegetables e.g. soup, etc would be fine.) (After the initial 21-30 days of the high dose, a subsequent dose of 3 - 6 tablets per day for the following three months is the proper protocol). The subsequent maintenance level is 2 - 3 tablets per day along with about 10 kernels per day. Studies show that cancer cannot grow anywhere else when there is amygdalin in the body.

Eating the kernels is different, ingesting vitamin B17 at much lower levels, usually more frequently. Whereas with the tablets it seems best to avoid eating raw fruit at the same time, when eating the kernels stated that it is also important to eat some nitrilosidic fruits, (e.g. apricots, peaches, plums, nectarines, apples, pears, cherries, grapes) There is something in the flesh of the fruit which will neutralise the minute traces of beta-glucosidase present in the saliva, the stomach and the intestines, which is what may cause some people to feel a bit nauseous.) Many people have found eating dried apricots together with the kernels works well.

NB. Dr Krebs recommended leaving 2 hours between eating kernels and concentrated laetrile tablets.

For prevention: if you do not have cancer Dr Krebs recommends eating 10 kernels daily. An alternative is taking one or two of the 100mg tablets per day. However, most people just eat the kernels. Dr Krebs states the whole food is best. This means eat the kernels no matter how bitter you think they are.

How soon should I expect results?

In 100% of skin cancer patients dramatic results are seen in just a few days. This is normal when the individual is taking at least 30 apricot kernels per day and a few of the B17 tablets. Bone cancers take the longest. Pain decreases over 80% of the time and completely stops over 50% of the time and is due to the stoppage of the cancer from getting larger and larger. Every cervical tumour we have dealt with has shrunk down within a couple of weeks. Carcinomas can take a few months to shrink.

Will the tumour completely disappear?

Most cancerous tumours will never completely disappear. This is where many people make their mistake of taking more chemotherapy to try to eliminate the tumour. My name is Jason Vale and I still have the tumour in my kidney. It shrunk down initially and then stopped shrinking. For oncology reports showing the tumour shrinkage see the website

Remember, a cancerous tumour is not fully cancer. It is mixed with benign cells and many times is only 5% to 50% cancerous. A tumour that is 5% cancer might only shrink 5%. A tumour that shrinks 5% will never come up as 'reduction in size' on the doctor's oncology report. It will be reported as 'no change'. The benign tumour is safe and in its core can even have some live cancer cells that have closed themselves off to the ongoing cyanide in the body ... (B17 and kernels). They are of no threat as long as you keep an adequate supply of nitrilosides (foods with B17 in them) in your food intake.

Can I take the B17 and chemotherapy together?

Yes. If you decide to have chemotherapy then taking the Vitamin B17 alongside will give extra strength to the blood and body as well as attacking the tumour. (However some people find it is difficult to do both at the same time and prefer to wait until their chemotherapy is over before starting on the B17 regime.) Please find out if there is any success rate with chemotherapy with the cancer you have. If the doctor says yes, then ask him if he means success as in cured, or success as in it might extend your life for a few months. If you are about to have an operation where the cancer cells are going to be disturbed, it is imperative that you take the kernels and the vitamin B17 to kill the free cells. Vitamin B17 can only help. It normalises blood pressure and is one of the healthiest foods on earth. It strengthens the arteries and heart and of course targets the cancer cells.

(Some of Jason Vale's other comments on chemotherapy: "If you have to do chemo make sure you don't overdo it. ... I've seen hundreds of people make the wrong decisions because they were expecting their tumour to disappear. Malignant (cancerous) tumours are only a small percent cancer and when the cancer part starts dying off the tumour only shrinks down the percent the tumour was cancerous. ... Most doctors will still see a tumour and continue to give a person chemotherapy (until they're dead) in attempts to make it disappear. ... Those that continue on with chemotherapy have a poor outcome.")

Can I have the kernels and the vitamin together?

Of course. There are many components of the kernels that are not included in the vitamin. The kernels have vitamin B17 in them as well as many other vitamins and minerals that help the actual vitamin B17 assimilate into the body. Remember our scientists have only identified about a thousand vitamins and minerals. They say that there are hundreds of thousands that are still not identified yet. That means that you cannot just be a supplement person. One study showed scientists feeding one group of rats all of the vitamins and minerals known. The second group was given garbage. The vitamin and mineral group was skinny and sickly after a couple of weeks, but the garbage eating group was, of course, strong and healthy. At the same token, a garbage eating group with supplements added can be even stronger. This study means always eat the whole foods along with the vitamins, as Dr Krebs states.

What should I take along with the vitamin B17?

The blood is the life of the flesh. Therefore Christian Brothers has put together a blood building blood cleansing package. Coral, enzymes and cansema (a herbal product containing chaparral, galangal, rhubarb, burdock, buckthorn, red clover, zinc oxide/zinc chloride, ascorbal palmitate).

(For other suggestions see Summary of Supporting Supplements).

Where can I go to get the injectable form administered?

You can just ask a nurse that will make a house visit to administer the injectable form. It is safe and non-toxic.

(For information on clinics in Mexico and Europe telephone Karen Kirkpatrick 01483 423235 (9am - 5pm Mon-Fri) in the U.K. This is a private line, if no answer - keep trying. Or phone Credence Helpline on 01622 832386)

Can it help me?

The kernels and vitamin B17 will help you even if you've been given a short time to live according to the medical prognosis. However, if the latter is the case, much more than just the vitamin B17 and the apricot kernels should be used.

See Summary of Supporting Supplements, Summary of Supporting Diet, Summary of Supporting Lifestyle and Recommended websites for suggested nutritional therapy and sources of supplements and other therapies which can work alongside vitamin B17.

If you have just been diagnosed and you're starting B17 therapy without chemotherapy or radiation you should be fine. Dr Krebs claimed a 98% rate and the Del Rio Hospital of Tijuana, Mexico claims nearly a 100% success rate with virgin cases. (A virgin case is an individual that has not had chemotherapy and/or radiation.)

Why don't medical doctors use vitamin B17? (In the USA)

Doctors are taught from the beginning while in school that Laetrile is not effective. On their own they are not allowed to use it or they will lose their license and face criminal charges. After attending years of medical school, internship and finally working in a hospital, most doctors only want to hear of the treatments they are allowed to administer, even if they are not successful. Only researchers can know the truth, those that seek knowledge. Start with Mr Griffin's book World Without Cancer.

The following notes give detailed information, from books and websites, of the recommended treatment for those with cancer.

World without Cancer website (not operational currently)

If you have cancer the most important single consideration is to get the maximum safe amount of vitamin B17 into your body in the shortest period of time.

  • Initial phase: B17: 3gms intravenous 2 times per day for 21 days. (2 vials directly into any vein or catheter) or 6 to 10 x 500mg tablets orally per day for 21 days.
  • Subsequent phase: 4 - 6 tablets per day for the following three months.
  • Maintenance phase: 1.5 gms (three 500mg tablets) orally per day, indefinitely.

It is good to take the apricot seeds with the B17 tablets - they contain components not included in the vitamin. A high intake of kernels is not necessary if you are taking tablets as well. Dr Krebs recommends 10 seeds daily for prevention. (But NB leave 2 hours between eating kernels and tablets.)

What should I take alongside B17? Worldwithoutcancer website quote Dr Contreras of the OASIS Hospital, Playas de Tijuana, Mexico. He recommends taking pancreatic enzymes, vitamin C, pangamic acid (B15), shark cartilage, vitamin A (emulsified), Barley Grass, antioxidants and other nutrients. The idea is to attack the cancer very aggressively, without doing any harm to the patient, while strengthening the immune system.

For those people who have had chemotherapy, radiotherapy and surgery, or damage from the cancer itself, there are other supplements which help - see the website (and others).

Oasis of Hope Hospital Website

At the Oasis of Hope Hospital in Baja, California, Mexico, which is 20 miles south of San Diego, California, U.S.A., the Contreras group of doctors treat the patient, not the disease. They will provide nutrition and non-toxic therapies that not only attack the cancer, but will equip the immune system to fight against the cancer itself.

A special detoxification program is included. The programs are eclectic and often include:

  • Laetrile (vitamin B17), enzymes, mega-doses of vitamins
  • Regenerating agents, Immune modulating agents
  • Organic foods and juices, Shark Cartilage
  • Antioxidants, Hormone therapy, O-Zone

Normally treatment is given over 21 days. However, the Oasis of Hope Hospital also offer a 4 day/3 night treatment designed for the person who is:

  • taking chemotherapy but wants to complement it with Alternative Medicine
  • wants to avoid the high price of 21 days treatment
  • does not have time for a 21 day stay at a hospital
  • not sure if Alternative Medicine is the best solution, but wants to try it

Binzel, Philip E. Alive and Well (American Media, California 1994)

Dr Binzel, an American GP, offered his patients vitamin B17 and nutritional therapy for 18 years until his retirement. His book covers the results of those 18 years. A summary of his therapy:

Whole objective of this nutritional programme is to do two things:

  1. To put into the body the nutritional ingredients that the body needs in order to allow its immunological defence mechanisms to function normally, and
  2. to take away from the body those things that are detrimental to the normal immunological defence mechanisms.

There are three parts to this programme:

  1. Vitamins and enzymes
  2. Nitrilosides (vitamin B17/laetrile/kernels)
  3. Diet

Vitamins and Enzymes to be taken with meals

  1. Multiple vitamin - 1 twice daily
  2. Vitamin C - 1 gram twice daily, increasing to at least 6 gms daily while taking high doses of laetrile. NB When reducing from high levels of vitamin C, please do so gradually.
  3. Vitamin E 400 units - 1 twice daily
  4. Univase Forte (formerly Megazyme Forte) providing pancreatic enzymes - 2 three times daily
  5. Pangamic acid (B15) 100mg - 1 three times daily
  6. Emulsified vitamin A providing 125,000 I.U. daily. (i.e. 8 drops of 'Vitamin A and E Emulsion drops')
  7. Binzel stresses the need for zinc, to be able to absorb the vitamin B17 - take separately if not in enzyme supplement. (A therapeutic dose is 15 - 50mg daily, or up to 150mg if deficient.)

Nitrilosides i.e. Vitamin B17

Dr Binzel uses Amygdalin (Laetrile) available in 500mg tablets and in vials (10cc-3gms) for intravenous use. The dosage he uses is as follows: for three weeks

  • intravenous Laetrile is given three times weekly for three weeks with at least one day between injections. Dosage: 1st dose 1 vial (3gms); 2nd and 3rd dose 2 vials (6gms); 4th- 9th dose 3 vials( 9gms).
  • The oral dosage is given in a dosage of 1gm daily (two 500mg tablets) on the days on which the patients do not receive the I.V. Laetrile. (adding the intravenous and oral doses together they total 79gms over 19 days i.e. average just over 4gms per day)

Dr. Binzel has them take both tablets at the same time at bedtime on an empty stomach with water. The water is important because there are some enzymes in the fruits and vegetables and in their juices which will destroy part of the potency of the Laetrile tablets while they are in the stomach. Once the stomach has emptied, this is no problem. (However, other sources recommend taking the tablets while having food in the stomach. Personally we have found having food in the stomach best - but not raw fruit or vegetables because they contain enzymes - see page 5.)

The next three months

Following this first three weeks of I.V. injections, the patient then has one injection of 1 vial - 3gms once weekly for three months. If the patient notices a considerable difference in the way he feels when the injections are reduced to once weekly, the injections are increased to two or three times a week for three weeks. This is repeated as often as necessary until the patient notices no difference with the reduced dosage. Eventually just one gram per day is taken orally, and this is continued indefinitely.

NB Dr Binzel does not start his patients on their Laetrile, either I.V. or orally, until they have been on their vitamins and enzymes and diet for a period of ten days to two weeks. He finds that the Laetrile seems to have little or no effect until a sufficient quantity of other vitamins and minerals are in the body. Zinc, for example, is the transportation mechanism for the Laetrile. In the absence of sufficient quantities of zinc, the Laetrile does not get into the tissues. The body will not rebuild any tissue without sufficient quantities of Vitamin C. When he starts the Laetrile he also increases the dosage of Vitamin C by 1 gm every third day until they reach a level of at least 6gms. (When reducing from high levels of vitamin C, please do so gradually.)

The level of nitrilosides in the body can be monitored. When the body metabolises nitrilosides, the by-product is thiocyanate. Thiocyanate levels in the blood can be measured. Dr Binzel finds in general, that patients who do best are those in whom the thiocyanate level is between 1.2 and 2.5 mg/DL. (A beneficial side-effect is that thiocyanate is known as a natural regulator of blood pressure.) (Griffin p 91). Laetrile is not the only source of nitrilosides. There are some 1500 foods that contain nitrilosides. These include apricot kernels, peach kernels, grape seeds, blackberries, blueberries, strawberries, bean sprouts, butter beans, and macadamia nuts. The advantage of taking laetrile is that it can raise the nitriloside level in the body (and, thus, re-establish the body's second line of defence against cancer) much more rapidly than can be done by diet alone.

Diet For patients:

If it is animal or comes from animals you cannot have it! i.e. all meat, poultry, fish, eggs, cheese, cottage cheese and milk. Reason: it takes large quantities of digestive enzymes to process animal protein (these are the enzymes that dissolve the protein lining of the cancer cells which can then be killed by white blood cells). Patient would be on this diet for a minimum of 4 months. To restore the enzymes back into the body for the first line of defence.

If it does not come from animal you can eat it, but not cook it! Reason: fresh fruit and vegetables contain important enzymes, but any temperature over 130 degrees will destroy enzymes. For this reason fruits and vegetables may not be cooked, canned or bottled. They may be frozen at home, but commercial frozen food has often been processed in some way. i.e. diet with lots of salads. Salad dressings: use vegetable oil and no refined sugar - use molasses or honey. Use sea salt in moderation, iodised is fine. Use herbs and spices. No white flour or white sugar. No food preservatives. Eat as wide a range of vegetables as possible. Aim for 60% vegetables and 40% fruit. Also wide variety of fruit - except for citrus fruits, eat the seeds of the fruit - apple seeds, grape seeds, apricot kernels, peach kernels, etc. have a high nitriloside content. Get protein from vegetables so that you use less pancreatic enzymes for digestion.

Protein content of diet can be cooked.
Wholewheat cereals, pasta, breads. Corn. Buckwheat high in protein.
Butter in small amounts - no margarine (see our comment below)
Nuts high in protein. (Not roasted peanuts because of an acid formed in roasting)
Dried fruit provide protein.
Beans when eaten for protein can be cooked. What can be eaten raw should be.
No milk other than what used on cereal and in cooking. (see our comment below) No caffeine. Herb teas OK.

At end of 4 months if patient is doing well, diet is liberalised. Add chicken, turkey and fish. 90% of the diet should be as above plus chicken, turkey and fish. Other 10% can be red meats, cooked vegetables and dairy produce.

Must always stay on vitamins, enzymes and laetrile (1gm daily).

Anticancerinfo comment on Binzel's regime: we would permanently cut out milk (and all dairy) entirely, substituting olive oil (in recipes substitute 1 tablespoon of olive oil for 1oz of butter), or use coconut oil as a spread - it is solid at room temperature in Northern Europe and is also good for cooking.

Griffin, G. Edward World Without Cancer (American Media, California 1974,1997)

Protocol for Laetrile for Cancer Patients

By 1974 Laetrile was being used intravenously 6-9gms daily. Generally it takes an accumulation of 50-70 gms over a period of about a week or 10 days before the patient can report tangible indications of improvements. (p33)

While the use of laetrile (B17) alone has proved to be effective in many instances, even better results usually are obtained with supplemental therapy as well. Dr John Richardson achieved one of the highest recovery rates among Laetrile practitioners (p110)

Dr. John Richardson's advice to patients (i.e. not for healthy people for whom it is unnecessarily restrictive)

Vegetable Kingdom Eat anything. Eat everything whole - all the edible parts, especially roughage. Preferably eaten raw. If necessary cook very lightly.

Animal Kingdom Eat any or all fish as fresh as possible and lightly cooked in the absence of animal fats. Eat the skin-free meat of poultry. Whatever does not fall within this formula, forget it. Don't eat it - i.e. no dairy products, beef, mutton, pork, bacon, ham, etc.

Vitamin supplements
Vitamin C 1.5 - 5gm
Vitamin E 800-1200 I.U.
Vitamin B15 (pangamic acid) detoxifies the liver, and increases the oxygen uptake potential of the tissues (cancer cells do not like oxygen)
Pancreatic Enzyme Supplementation - desiccated pancreas substances

Beverages: Adequate liquid intake with fresh juices plain or carbonated. Avoid alcohol, coffee.

Avoid toxins of all kinds including tobacco, alcohol, coffee, tranquillisers, sedatives, analgesics. Antibiotics OK.

Rest is important, while exercise should spare the affected area. see especially



This is a lot of information to take in. Unfortunately time is of the essence when someone has cancer, but it is worth trying to think carefully about what action to take. It is true that it is perfectly feasible to take the vitamin B17 and nutritional therapy alongside chemotherapy and radiotherapy. However, it has to be recognised that the people who have worked with cancer patients state that they have a much better success rate with patients who have not been subjected to chemotherapy and radiotherapy, both of which harm healthy cells as well as cancer cells. As cancer is a chronic metabolic disease, and such diseases have only ever been cured by a change in nutrition, then hitting the immune system with toxic substances might seem to be counterproductive.

If you are considering orthodox treatment, it would be worth asking what the success rate is, 'success' not meaning just being kept alive for a few more weeks or months with a quality of life greatly affected by the treatment. During his ten years as a statistician, Dr Ulrich Abel discovered that the method used for treating the most commonly occurring epithelial cancers (lung, breast, prostate, colon and other organs) has rarely been successful. Abel published a summary of the results of chemotherapy, Chemotherapy for Advanced Epithelial Cancer, in 1990.1 Some of the findings Dr Abel published are:

  • Colon and rectal cancer: There is no evidence at all that chemotherapy prolongs the life of patients
  • Stomach cancer: There is no evidence of effectiveness.
  • Pancreatic cancer: The largest study was "completely negative". The patients who experienced prolonged life were those who did not receive chemotherapy.
  • Bladder cancer: Chemotherapy is often applied but is not effective. No prospective study has been made.
  • Breast cancer: There is no evidence that chemotherapy raises the chance for a patient's survival. Its use is "ethically questionable".
  • Ovarian cancer: There is no direct evidence, but it might be worthwhile to research the use of platinum.
  • Uterine and cervical cancer: There was no improvement in the survival rate of those treated with chemotherapy.
  • Cancer of the head and neck: There was no benefit to receiving chemotherapy in terms of survival. There was the occasional benefit of reduction of tumour size.

'The fact is, for most of today's most common cancers, the ones that kill 90% of cancer patients every year, chemotherapy has never been proved to do any good at all and in fact may do harm.'2

The testimonies contained in the book by Dr. Philip E. Binzel Alive and Well (American Media, California, 1994) are worth reading. They are very encouraging. The book World Without Cancer by Edward G. Griffin (American Media, California 1974 and 1997), and the video3 by the same name give an account of the story of vitamin B17 and nutritional therapy. After watching the above video Dr Binzel started treating his patients with B17 and nutrition therapy. This book covers the 18 years from that time until his retirement and the phenomenal results that he had. See the notes 'B17 - does it work?' for results with patients at the Oasis of Hope hospital in Mexico which are dramatically better than those of conventional therapy.4

Most people reading these notes will either have cancer themselves or be reading them with someone else in mind who has cancer. Hopefully these notes will help make a more informed decision, and lead to other websites and publications for more details and organisations for more help. There are many actions that can be taken by individuals themselves to fight cancer. One of the most important is to try and work out what triggered the cancer in the first place. If this is not dealt with then the cancer is more likely to come back again even if treatment is at first successful. See 'Maintenance lifestyle for those who have had cancer' for action to take in addition to diet.

For those people who have had cancer and are now in remission, the information contained here will hopefully convince of the need to take action, even if the cancer is not currently a problem. Seize the opportunity to adjust diet and include foods containing vitamin B17, check pH levels and perhaps even have a month of a more concentrated regime to blitz any cancer cells which might be as yet unseen. People who have had cancer once are more susceptible, and perhaps need to take greater care.

Those who are looking after cancer sufferers are likely to be concentrating their attention on them. However, for cancer to become a thing of the past, a rare disease, it is necessary for us all to take note, and take action. It is far easier to take action before getting cancer, than afterwards. Dr Krebs, who first produced laetrile, the concentrated form of vitamin B17, was concerned that people should nevertheless obtain vitamin B17 from their food. There are many sources of this (see the notes 'Cancer Prevention - a change in our diet'). However, an easy way to make sure of taking vitamin B17 is to eat 10 apricot kernels per day for life (in two lots of five kernels with at least an hour inbetween). This amount will help prevent cancer. According to Dr Krebs if we all did this it is likely that cancer could be confined to the history books.
