B-17B-17 is NOT a vitamin in any way, shape or form. It is a glycoside and also known as laetrile and amygdain, and it can be toxic. Fourteen vitamins are recognized in human nutrition (Vitamins A, D, E, K,Vitamin B1 (Thiamine), B-2 (Riboflavin), B-3 (Niacin), B-5 (Pantothenic acid), B-6 (Pyridoxine and Pyridoxamine), B-7 (Biotin) Vitamin B-9 (Folic acid), B-12 (Cyanocobalamin) C, folacin, choline.
The substance B17can be extracted from the seeds of the bitter almond tree. Amygdain can also be extracted from the kernels or cakes of the bitter almond or the apricot.
Real research is published in peer-reviewed journals, not on personal and business websites. There was a case in Ireland in 2005 of a woman who had been taking the so called vit B17 who had cyanide poison

www.ncbi.nlm.nih.gov/pubmed/16014371?dopt=AbstractBeta-glucosidase, one of the enzymes that catalyzes the release of the cyanide from amygdalin, is present in the human small intestine and is in a variety of common foods. This leads to an unpredictable and potentially lethal toxicity when amygdalin or laetrile is taken orally.
Vit CVitamin C or L-ascorbic acid or L-ascorbate is an essential nutrient for humans. Vitamin C is a water-soluble vitamin, one that cannot be stored by the body except in insignificant amounts. It must be replenished daily. Like other vitamins, vitamin C is an organic compound. An organic compound is a substance that (1) occurs in living things, or organisms (hence, the word "organic") and (2) contains the elements carbon and oxygen, it helps produce collagen, a protein needed to develop and maintain healthy teeth, bones, gums, cartilage, vertebrae discs, joint linings, skin and blood vessels. It also does the following promotes the healing of cuts abrasions and wounds, helps fight infections, inhibits conversion of irritants in smog, tobacco smoke, and certain foods into cancer-causing substances, appears to dilate (widen, enlarge) blood vessels and so lessens the risk of developing high blood pressure and heart disease, aids in iron absorption. It also helps regulate cholesterol levels. And what its known most for it prevents the development of scurvy. Scurvy is rare today. (
It is available in the following foods -
Fruits - oranges, lemons, limes, grapefruits, tangerines, pears, bananas, melons, papayas, strawberries, mangos, blackberries, blueberries, kiwis, pineapples, watermelons, raspberries, cranberries, cantaloupes, rose hips, acerola cherries.
Vegetables - asparagus, broccoli, green peppers, red peppers, cabbage, kale, cauliflower, potatoes, sweet potatoes, yams, squash, peas, turnips, turnip greens, onions, corn, pumpkins, carrots, parsley, sauerkraut.
Herbs - garlic, watercress.
Also fish and milk
Some people taking
large amounts of vitamin C may experience diarrhea, nausea, skin irritation, burning upon urination, and depletion of the mineral copper. Also, there is some evidence that large doses of vitamin C may contribute to the development of kidney stones. Laboratory studies have shown that vitamin C can induce the formation of genotoxins (agents that damage DNA). If generated in significant amounts, these genotoxins could generate mutations and so conceivably contribute to cancer.
Vitamin C can cause adverse reactions when taken with some drugs. Vitamin C may increase adverse effects associated with acetaminophen or aluminum-containing antacids such as aluminum hydroxide (Maalox®, Gaviscon®).
Vitamin C may increase blood levels and adverse effects of aspirin, whereas aspirin may decrease blood levels of vitamin C.
The effects of vitamin C may be decreased by barbiturates including phenobarbital (Luminal®, Donnatal®), pentobarbital (Nembutal®), or secobarbital (Seconal®).
Vitamin C supplementation may decrease levels of the drug fluphenazine in the body.
Concomitant administration of high doses of vitamin C can reduce steady-state indinavir plasma concentrations.
There is limited case report evidence that high dose vitamin C may reduce side effects of levodopa therapy such as nausea or malcoordination.
Nicotine products such as cigarettes, cigars, chewing tobacco, or nicotine patches may decrease the effects of vitamin C.
Oral estrogens may decrease the effects of vitamin C in the body. When taken together, vitamin C may increase blood levels of ethinyl estradiol.
The effects of vitamin C may be decreased by tetracycline.
Vitamin C in high doses appears to interfere with the blood thinning effects of warfarin by lowering prothrombin time (PT).
High doses of vitamin C are not recommended in patients with kidney failure. Caution is advised when taking vitamin C and drugs that may damage the kidneys due to an increased risk of kidney failure.
Interactions with Herbs and Dietary Supplements
When taken together, vitamin C may increase the absorption of iron in the gastrointestinal tract, although this effect appears to be variable and may not be clinically significant.
Vitamin C may increase absorption of lutein vitamin supplements.
Large doses of vitamin C may interfere with the absorption and metabolism of vitamin B12.
In theory, large doses of vitamin C may also interact with herbs and supplements with hormonal, antibacterial and blood thinning (anticoagulant) activity.
