Vitamin B17 (амигдалин, лаэтрил)

Vitamin B17, also known as amygdalin or laetrile, draws attention both in scientific circles and among the general public.

Since its discovery, this nutrient has been the subject of numerous discussions and debates regarding its role in human health.

Vitamin B17 is a glycoside that contains hydrogen cyanide. Its chemical formula is C17H23N1O8, and it consists of several components, including glucose, benzaldehyde, and cyanide. This structure allows the body to release cyanide, which sometimes raises debates about the safety of its consumption.

The History of the Discovery of Vitamin B17

Vitamin B17 was discovered in the early 20th century. Initially, it was studied by Dr. Ernst T. Krebs, who found that this compound is present in the seeds of fruits such as apricots and apples.

In 1952, Krebs published a paper claiming that B17 may have anti-cancer properties. However, his ideas sparked controversy in the medical community, and many scientists began investigating the potential risks associated with its consumption.

Despite the lack of official recognition, interest in vitamin B17 continues to persist, and research on it is still ongoing.

Sources of Vitamin B17

Sources of vitamin B17 include:

• apricot pits;
• peach pits;
• almonds;
• cherry seeds.

However, it is important to note that the content of amygdalin in these products may vary.

Possible forms and their learnability

Nutrient forms are listed from best to worst:

Injectable laetrile (intravenously or intramuscularly). Synthetic form of amygdalin, administered directly into the bloodstream. This form bypasses the digestive system, reducing the risk of cyanide release in the intestine. However, scientific studies have not confirmed the effectiveness of laetrile in cancer treatment, and its use may be associated with serious side effects.

Oral amygdalin (tablets or capsules). When ingested, amygdalin is broken down in the digestive tract, which can lead to the release of cyanide. This increases the risk of poisoning, especially when consumed with foods rich in vitamin C or beta-glucuronidase, which enhance the release of cyanide.

Natural sources of amygdalin. The seeds of some fruits contain amygdalin. However, their consumption can lead to the release of cyanide, especially when consumed in large quantities, which poses a serious health risk.

Role in the Human Body

Vitamin B17 plays a controversial role in the human body. It is believed that it may help improve metabolism and possesses antioxidant properties.

There are opinions that B17 may support the immune system and increase energy levels.

Some studies suggest that it may have anti-cancer properties by promoting apoptosis of tumor cells. However, this data is not conclusive, and further research is needed to confirm these claims.

In the 1970s, experiments were conducted suggesting that amygdalin could help in cancer treatment, but clinical trials did not confirm its efficacy.

Some sources claim that it helps normalize blood sugar levels.

Nevertheless, further research is needed to verify these effects.

It is important to remember that excessive consumption of vitamin B17 can lead to toxicity and negative health consequences.

Risks of Use

Consumption of vitamin B17 may pose risks, especially at high doses. Below are some potential issues:

• toxicity: vitamin B17 can release cyanide, which can be harmful to health if recommended doses are exceeded;
• allergic reactions: some individuals may experience allergies to the components found in vitamin B17 supplements.

It is important to consult a doctor before starting to take supplements containing vitamin B17.
