What is B17 and its benefits?
Vitamin B17 is a supplement derived from apricot pits and other natural sources. The chemical name for this compound is Amygdalin or Laetrile. Extracted from the seeds of certain fruits and tree nuts, Amygdalin is found in more than 1,200 different foods such as apple seeds, almonds, cashews, plums. However, in nature the highest concentration of Amygdalin is found in Raw Bitter Apricot Seeds. Vitamin B17 can be used as a supplement and is beneficial to overall well-being, promoting optimal health.
Is B17 legal?
Absolutely! Before implementing any vitamin or nutrient into your diet it is always recommended to consult a health practitioner. Leave that up to your doctor—they're the experts!
Why is B17 important?
A balanced diet is essential to a healthy life, and few of us consume enough vitamins and minerals from the foods we eat. B17 contains powerful immunity-boosting properties to strengthen your body's natural defenses.
How should I take B17 for health benefits?
B17 is most commonly taken in the oral form via Raw Bitter Apricot Seeds, Apricot Seed Meal, bars, or capsules. B17 can also be administered intravenously.
Are there any side effects of taking B17?
B17 is generally considered safe when taken within recommended dosage guidelines. However, some individuals may experience an upset stomach. This is due to the interaction of Amygdalin/B17 with the beta-glucosidase enzyme found in high concentrations in cells with abnormal growth. The beta-glucosidase enzyme breaks down the B17 and releases the cyanide and benzaldehyde which together attack abnormal cells and release the toxins within them. It is these toxins that can cause nausea, but rest assured this is a good sign of progress.
It's important not to exceed recommended dosages. If you have any questions please advise with your trusted medical practitioner.

Do the Nutriseeds vitamins (B17, B15, Pro enzymes) interfere with other supplements or medications?
Upset stomach/nausea - This is a sign of the B17 and other RNC vitamins attacking the abnormal cell growth. When the abnormal cells die (apoptosis) they release toxins into your body, this is what causes the upset stomach for some individuals. With water, good diet, and exercise these toxins are flushed out of your body and gone with it any upset stomach or nausea you may have had.
Blood pressure medication - B17 is known to naturally reduce high blood pressure. This means that if you have low blood pressure and you are taking medication to increase your blood pressure, the Apricot Seeds and other B17 products may reduce the effectiveness of those medications because B17 itself is known to help increase and restore your blood pressure. In this way B17 may be able to help someone get off blood pressure lowering drugs.All supplements offered by Richardson Nutritional Center (RNC) are found in nature and have not been adulterated in any way. They are food products and not medications.
What is the purpose of taking Pro Enzyme and B15 along with Laetrile?
Pro Enzyme is our in house blend of digestive enzymes that help oxygenate the blood and assists with exercise and stamina. These enzymes aid in digesting animal proteins and offer various other benefits.
B15 has benefits related to oxygenation and can contribute to exercise and stamina as well.
Dr. John Richardson had both B15 and Digestive Enzymes in his protocols

Are there any specific guidelines for consuming Apricot Seeds?
Yes, it's essential not to consume Apricot Seeds at the same time as taking pure Amygdalin (Laetrile) capsules. This is because Apricot Seeds contain a certain amount of the enzyme Beta-Glucosidase, which can lead to the release of excess cyanide and benzaldehyde when taken together with Laetrile Capsules.
Is it harmful to ingest Apricot Seeds and Laetrile together?
While it is not inherently harmful, ingesting both Apricot Seeds and Laetrile simultaneously can lead to an upset stomach. It is recommended to wait three hours in between to prevent any discomfort.
Why is it recommended to ingest Apricot Seeds separately from Laetrile?
It is recommended to consume Apricot Seeds separately from Laetrile to prevent potential discomfort and upset stomach. When taken together, the combination of surplus beta-glucosidase in the seeds and the presence of Laetrile extract can burden the immune system, leading to instances of nausea and lightheadedness.
How can I counteract an upset stomach caused by consuming Apricot Seeds and Laetrile Capsules together?
To counteract an upset stomach, you can consume dried apricots, which contain the enzyme Rhodanese. Rhodanese can help mitigate the side effects of consuming Apricot Seeds and Laetrile Capsules together.

The three-hour interval recommendation primarily applies to individuals who have experienced instances of nausea when consuming both forms together. Some individuals may not have this issue and can adjust their timing accordingly based on their tolerance and gut microbiome composition.
Does Vitamin B17 contain cyanide?
In short: Yes, Apricot Seeds, as well as apple seeds, lima beans, yuca, flax seeds, spinach and other common foods we consume all contain a locked form of cyanide bearing compounds. It is important note that Vitamin B17 does NOT contain free cyanide radicals.In depth: In his book World Without Cancer; The Story of Vitamin B17, G. Edward Griffin discusses the breakdown of the cyanide component. The following information is for educational purposes only. Griffin explains that Laetrile, or Vitamin B17, contains two molecules of glucose, one molecule of benzaldehyde, and one molecule of hydrogen cyanide (HCN) all tightly locked togetherLaetrile, when consumed orally, is said to selectively target abnormal cell growth due to the enzyme beta-glucosidase that is present in higher concentrations in the abnormal cells compared to normal cells. This enzyme helps break down Laetrile, releasing the cyanide within the abnormal cells.The cyanide produced from Laetrile within abnormal cells is present in a form called Cyanohydrin. It is claimed that this molecule is relatively stable and does not easily release Free cyanide. According to Griffin's book, normal cells also contain Rhodanese, which converts cyanide to Thiocyanate in the presence of sulfur, minimizing the toxicity of cyanide. However, normal cells are supposed to have a protective mechanism that can neutralize any potential harm caused by the small amount of cyanide produced. Abnormal cells allegedly lack this protective mechanism, making them more susceptible to the toxic effects of cyanide.
