What is Vitamin B17 (Amygdalin)

Vitamin B17, commonly known as amygdalin, is a naturally occurring compound found in various nuts, plants, and seeds, including apple, peach, almond, cherry, and apricot seeds. Its scientific name is D-mandelonitrile-b-D-glucosido-6-b-D-glucoside.

Amygdalin has garnered attention in alternative health circles for its proposed medicinal properties. It is often confused with Laetrile, but the two are not the same.

Laetrile, a patented drug developed by Dr. Ernst T. Krebs, Jr. in 1952, contains a purified form of amygdalin and was originally marketed as a cancer treatment. To avoid the stringent regulations associated with pharmaceuticals, Laetrile was introduced under the label of vitamin B17, allowing it to be classified as a supplement instead of a drug. This strategic branding made it easier to promote, despite ongoing debates regarding its efficacy and safety in conventional medicine.

While the FDA does not recognize amygdalin as a legitimate cancer treatment, it remains a topic of interest in alternative health practices, where proponents suggest it may offer various health benefits.

Food Sources of Amygdalin (Vitamin B17)

Amygdalin, or Vitamin B17, is naturally found in a wide range of plant-based foods, particularly in the seeds and pits of certain fruits. While it’s often highlighted for its presence in apricot kernels, there are many other foods that contain this compound. Including these foods in your diet has become popular among those seeking natural ways to improve health, though it's essential to consume them in moderation due to potential cyanide toxicity when ingested in large amounts.

Here are some of the most common food sources of amygdalin:

• Apricot Kernels: One of the richest sources of amygdalin, often used as a natural supplement.
• Bitter Almonds: Contain higher amounts of amygdalin compared to sweet almonds.
• Apple Seeds: Though small, apple seeds are packed with amygdalin. Care should be taken not to overconsume them.
• Peach Pits: Another fruit seed rich in amygdalin, found within the hard pit of the peach.
• Plum and Cherry Pits: Like peaches, the pits of these fruits contain significant levels of amygdalin.
• Lima Beans: Some varieties of beans, such as lima beans, also contain amygdalin, though in lower amounts.
• Cranberries: An unexpected source, cranberries contain small amounts of this compound.
• Flaxseeds: Known for their other health benefits, flaxseeds also contain trace amounts of amygdalin.

Including these foods in your diet provides a natural intake of amygdalin, but it’s vital to balance consumption to avoid potential side effects associated with excessive amounts.

How Does Amygdalin (Vitamin B17) Work

When amygdalin (Vitamin B17) is ingested, it goes through a metabolic process that involves the release of several compounds, including benzaldehyde, glucose, and hydrogen cyanide. While cyanide is toxic in large amounts, the way amygdalin interacts with the body varies depending on dosage and individual metabolism.

Once ingested, amygdalin is broken down by specific enzymes in the digestive tract. The compound’s key components—glucose, benzaldehyde, and hydrogen cyanide—are released into the bloodstream. It’s the cyanide element that raises concerns about toxicity, as it has the potential to interfere with cellular respiration, which can be dangerous if accumulated in significant amounts. However, proponents of amygdalin believe that, in small, controlled doses, the body can detoxify and neutralize the cyanide through natural processes like conversion into thiocyanate, which is less harmful and is excreted via urine.

Amygdalin is also thought to provide antioxidant benefits due to the release of benzaldehyde, which has properties that may help combat oxidative stress. Additionally, some believe the glucose released during metabolism may support energy levels by providing a quick source of fuel for the body.

Though these mechanisms are often cited by alternative health advocates, it's crucial to note that scientific support for such claims remains limited, and the safety of amygdalin as a health supplement is a topic of ongoing debate.

Dosage and Forms of Amygdalin (Vitamin B17)

Amygdalin is available in several different forms, each with its own specific dosage and method of administration. The form chosen often depends on individual health goals, the recommendation of a healthcare provider, and personal preference. Here are the common forms of amygdalin and how they are typically used:

• Capsules: This is the most popular and convenient form of amygdalin. Capsule dosages typically range from 100 mg to 500 mg per capsule, and users are usually advised to take 1–2 capsules daily, depending on their specific needs and health goals. This form is often favored for daily supplementation.
• Powder: Amygdalin powder can be mixed with liquids, such as water or juice. The standard recommended dosage is about 1/4 to 1 teaspoon per day, depending on the concentration and the individual's needs. Powders allow for more flexible dosing but require careful measurement to avoid overconsumption.
• Liquid Extract: Liquid amygdalin is taken in smaller doses, typically ranging from a few drops to half a teaspoon mixed into water or taken directly. This form is ideal for those who prefer not to take capsules or powders.
• Intravenous (IV) Therapy: In some alternative therapies, amygdalin is administered intravenously (IV) under medical supervision. IV amygdalin bypasses the digestive system and is delivered directly into the bloodstream, allowing for faster absorption. Dosages for IV administration vary and are usually much higher than oral forms, with doses typically given over the course of several weeks in specific clinical settings. This form is generally used in alternative cancer treatment clinics, though it remains highly controversial due to safety concerns and lack of regulatory approval.

Given the potential for toxicity, especially with higher doses or IV forms, it is essential to consult with a healthcare provider who has experience with amygdalin before beginning any form of supplementation.

Amygdalin Benefits

While amygdalin is not approved by the FDA for medical use, its purported benefits in alternative health are often cited by advocates. Some of the claimed benefits include:

• Cancer Treatment: The most significant claim is its potential to fight cancer by releasing cyanide into cancer cells, which allegedly kills them without harming healthy cells. However, scientific support for this claim is limited.
• Boosts Immune System: Amygdalin is believed to strengthen the immune system by increasing white blood cell production, although this has not been definitively proven.
• Pain Relief: Some users report pain relief after taking amygdalin, particularly those dealing with chronic conditions or cancer.
• Detoxification: Advocates claim that amygdalin helps detoxify the body by aiding in the removal of harmful substances, though this effect lacks rigorous scientific validation.
• Improves Energy Levels: By enhancing metabolism and removing toxins, some believe that amygdalin can boost energy and reduce fatigue.

It is important to note that most of these claims are anecdotal, and rigorous clinical research does not support the use of amygdalin for these purposes.

Amygdalin Precautions

Before using amygdalin, there are several critical precautions to consider:

• Consult a Healthcare Professional: Since amygdalin releases cyanide when metabolized, it is essential to consult with a healthcare professional before starting this supplement to ensure it is safe based on your personal health history.
