I have been around Vitamin B supplementation since the 1960s. I never heard of what you are suggesting.

There are endless professional scientific studies indicating the clear benefits of vitamins and other supplements.

The US NIH has recognized a wide range of these things.

If there is some kind of fringe problem with vitamin B6, that is only now being discovered, then we should, by all means, attend to those issues. Of course, there may be professional studies countering the idea that these levels of B6 are dangerous, I don't know. That is the nature of professional studies. There are, frequently, professionals who disagree. I know a bit about it, my ex was a 9 year post doc cancer researcher. Oh, yes, quite true. And yes, I helped her with her grant proposals.

So, while I don't have an MD or a Phd., I do know a few things.

So, for example, you took a supplement and four months later had a medical problem. That does not mean the two things are related. There could have been other, endless causes and the B6 was only coincidental during the period when the actual cause initiated the problems.

Or not. So, I take a Tylenol. Then, I get leg cramps. Did the Tylenol cause the leg cramps? Or were the leg cramps from doing my morning jog, but jogging twice the distance I usually jog?

Dr. Weil is an MD. He went to college. He got excellent grades. He got into medical school and graduated. He is a documented expert and professional. His advice is professional advice from an MD.

Anytime, anywhere, anybody suggests some herb or tea or vitamin can aid health, there is an immediate attack that tries to suggest all such things are nonsense. If you get into the science of it, that, oh....peppermint tea has no benefit, is really like saying that a healthy salad with leafy green vegetables can't possibly be good for you. That is the nonsense, the spin, the scam, the lie.

Of course supplemental nutrients aid health. Now, if you decide to drink 100 ounces of carrot juice daily and have some kind of toxic reaction to high levels of beta-carotene? Sure. If you do anything extreme, it can be dangerous.

I used to do accounting in a funeral home. One of the directors had been a rep for Big Pharma. He told me directly, that he and the other salesmen, used to go out for beers and laugh at how little of a bribe it took, for doctors to prescribe the drugs they wanted.

So, you know...please already, with the idea that every tea bag of chamomile tea is going to end civilization. Anytime big money is involved, there is plenty of corruption. And big Pharma deals in billions. And if you want corruption ...that is home base for it. Tormenting the poor, the disabled, and seniors with ridiculous prices for their life saving medication.

I personally witnessed an elderly lady at a local business, deeply upset because the insurance made a mistake and she was going to be charged $150 for blood pressure medication that usually cost her $15. She did not have the money. She was afraid without her medication, she might die. She was a nice lady that I had dealings with. I came up with the $150 to make sure she would not drop dead.

So please, re corruption and medicine. Any system that will let a nice elderly lady drop dead, because of ridiculous obstructive and abusive rules...is the enemy of decent society.

I take a multi-vitamin with B vitamins. I honor information. I honor knowledge. Because of what you wrote, before I would engage with a B vitamin complex with a large amount of B6, yes, I will look into it.

I respect information.

"Food sources of vitamin B-6 include poultry, fish, potatoes, chickpeas, bananas and fortified cereals."

It is a natural substance. So, if you are proposing the idea that B-6 had a toxic effect on you, you really ought to investigate the full range of foods and other exposures you had during that time.
Because there is every chance, the B6 levels were coincidental, and the real danger to you is out there, undiscovered.

So, say the levels you took were the equivalent of a can of chickpeas. That would be evidence that it is probably not the B6 that caused your problem. If the levels of B6 were the equivalent of 100 cans of chickpeas, a level of the substance you would never encounter in nature...then, sure, something like that could cause a problem.
