Vitamin B17, which is another name for amygdalin (laetrile is a purified form), has been used to prevent and treat cancer worldwide. Found in fruit pits, raw bitter almonds, and other plants such as millet and bean sprouts, cyanide is believed to be the cancer killing compound in amygdalin.
Buying Vitamin B17
Buying B17 Tablets from Health Food Stores:
The FDA does not allow information regarding potential medical benefits of Vitamin B17 to be posted or sold in the same area where supplies of B17 supplements are sold. Therefore, you should memorise or bring written dosage information with you to your local health food store (see "tips" for additional information).
Buying B17 Tablets Online:
It is easy to find sellers of B17 on the Internet by doing a search for "buy Vitamin B17." Check the location of the manufacturer and research the seller if possible. Laetrile from Mexico has been found to contain bacteria and other substances.
Buying Food Sources of Vitamin B17:
Raw apricot seeds (seven to ten a day) are thought to be the best natural source of Vitamin B17 (purchase online if you can't find them in your local health food store). Other sources include flax seeds and flax oil, barley, raw bitter almonds, lima beans, mung bean sprouts (approximately one cup constitutes a good serving of B17) and millet.
- Despite lack of FDA approval, a movement in alternative medical circles claims that Vitamin B17 is effective in the prevention and treatment of cancer. This camp claims the reason no controlled clinical trials have been conducted on laetrile is pharmaceutical companies have no incentive to pay for research, since amygdalin is available in foods that can be purchased at the supermarket.
- Dosage Information: "The Nature of Cancer" by Dr. Ernst Krebs is widely quoted in the alternative medical community as a source of Vitamin B17 dosage information. He recommends 100 mg tablets a day for cancer prevention and 500 mg a day (2 100 mg tablets taken 3 times a day) for cancer treatment. The 500 mg dosage may cause nausea and gastric problems. It may be beneficial to start with a smaller dosage and work up to 500 mg over the course of a few weeks.
- According to the National Institutes of Health's National Cancer Institute, anecdotal reports and laboratory and animal studies conducted on laetrile show little evidence that it is effective in the treatment of cancer. It is not FDA approved.
- Potential side effects include: vomiting, headache, dizziness, blue-looking skin from oxygen deficiency, liver damage, low blood pressure, sagging upper eyelids, nerve damage causing walking problems, fever, mental confusion, coma and death.
