Why is vitamin K7 illegal when its properties are known to prevent/cure cancer?

There is no K17.

Apricot seeds are very poisonous anyway. They contain enough cyanide to kill a small child.

Yikes. ;O

That is bad....

Great answer my2cents. ;))

Thank you. 

Your most welcome. ;))

I didn't catch this before, but she asked about K17 (no such thing), not B17, which is a completely different chemical. B17 is not a vitamin, but is actually a substance called amygdalin.. Its other name is Laetrile and was experimentally trialed in cancer research but showed only negative effects. Some thought it a wonder drug and were able to get it in Mexico as it was illegalized here. Steve McQueen was one of those patients but the cancer, caused by asbestos, got him at age 50. The treatment was useless.

Anytime #2 is brought up, I have to question it's validity.

Who has more power?  Pharmaceutical companies, or healthcare providers (hospitals, hospices, assisted-living centers, etc)?
Consider that treating cancer is a money hole ... and the "big name" treatment centers such as the Mayo Clinic and Shriners Hospitals have to get funding from other sources (donations, grants) to help pay for it.

I say if there was really an inexpensive way to treat cancer, healthcare providers would demand its availability.
Imagine the uproar Shriners Hospitals could cause with an ad campaign.  If you've ever seen their current ones, you know what I'm talking about.
Not to mention the pressure due to 60 Minutes and other investigative shows doing stories on such a conspiracy to prevent health care to millions of Americans (especially children).

You are most welcome to question anything you want... I am a Brit lol we are not the home of the conspiracy theory,  i must have been listening to too many Americans :P 
However, that said it is true that big pharma has a lot of power, how do we know this? Because factually, in the land of non-fake news we have seen many times where big pharma have overcharged the NHS for meds and they have continually brought out new brands, at a more expensive price, but with same ingredients just so they can charge more... they are known to hold their prices too high and refuse to reduce them... again costing the NHS millions that could be better spent. So this is fact not hype. 

Ir may well be the case that we have differing perspectives because we have slightly different set ups re the healthcare.. most of ours is provided by the govt. They don't have the power that perhaps private, money making health providers do.

Actually I got it from a nutritionist named Dr. Wallick. He was the one responsible for suing the FDA to make vitamins, all vitamins, legal. They used to be illegal. I give some credit to a Doctor who won such a revolutionary law suit against the FDA in favor of making vitamins available for everyone.

The FDA is now considering imposing stricter regulations on vitamins and supplements
Too many manufacturers make blatantly false claims and the ingredients aren't actually what is listed.

(that should do away with 99% of "diet supplements" on the market, at least)

Thats good. Most main stream vitamin suppliments are crap. The human body needs a total of 90 vitamins and minerals to stay healthy. Most store brands only have a fraction of that. ;o
