“Vitamin” B6 — A nerve toxin!

Based on my research below, I stopped taking B complex vitamins, specifically to avoid B6. I also stopped taking my ultra magnesium supplement, which had a high amount of B6.

Instead, I have had to start taking B vitamins individually. So far, I have only settled on taking 4-6 of them.

B1, B2, B7, and B12 I decided to take regularly.

B3 (niacin) I’m skeptical of taking, but I may take it occasionally.

B5 (pantothenic acid) I may also take occasionally, as it can be good to help tolerate the cold weather.

The body can synthesize B3 with proteins and B12.
The body can synthesize B5 with B12.

There are several key questions to ask about B6:

What is it? An alcohol.
What does it do? ??
Does it fit the definition of a vitamin? Maybe not.
Does it heal any deficiency disease? Maybe not.
Can the body make it? They say no. But I wonder.
How rare is deficiency? Very very rare.
What causes deficiencies? End stage kidney disease, or alcoholism, or drugs.
Do we need to supplement? Maybe not.
What is the RDA? 1.3 mg.
What is the upper limit? 21 mg – 100 mg
What are the toxic results at the upper limits? NERVE DAMAGE AT 200 MG, 500 mg, and 1000 mg.

What is it? pyridoxine, an alcohol

The RDA is 1.5 mg.

The highest food sources are:

Chickpeas, canned, 1 cup 1.1 mg
Beef liver, pan fried, 3 ounces 0.9 mg
Tuna, yellowfin, fresh, cooked, 3 ounces 0.9 mg
Salmon, sockeye, cooked, 3 ounces 0.6 mg

https://en.wikipedia.org/wiki/Vitamin_B6#History

“In 1934, the Hungarian physician Paul György discovered a substance that was able to cure a skin disease in rats (dermatitis acrodynia).”

What is Acrodynia?

https://en.wikipedia.org/wiki/Acrodynia

“Acrodynia is a condition of pain and dusky pink discoloration in the hands and feet most often seen in children chronically exposed to heavy metals, especially mercury.”

Mercury toxicity IS NOT a vitamin deficiency!

If this is a fraud, was it fraudulently established as a vitamin?

Maybe so?!

“Groups at Risk of Vitamin B6 Inadequacy
Frank vitamin B6 deficiencies are relatively rare in the United States”

Vitamin B6 and Health
–basically, not proven to do anything useful.

B6 as nerve toxin:

“However, chronic administration of 1–6 g oral pyridoxine per day for 12–40 months can cause severe and progressive sensory neuropathy characterized by ataxia (loss of control of bodily movements) [10,30-33].”

B6 is far more toxic than copper sulfate, a nerve healer.
Other nerve healers, such as B12, B1 and B2, have no upper limits!

Why is 50 mg of B6 (a nerve toxin) a standard in “high quality” B Complex vitamins?

Why is 50 mg of copper sulfate (a nerve healer) such a radical concept?

The upper limits of B6 in the USA is 100 mg. You can get that in 2 B Complex pills.

The upper limits in other nations are as low as 24 mg(!), half the dose in a single B complex dose.

In the Netherlands, it’s 21 mg, maximum dose!

https://www.lareb.nl/en/news/maximum-daily-dose-of-vitamin-b6-in-dietary-supplements-has-now-been-legally-established-in-the-netherlands

“The Netherlands Pharmacovigilance Centre Lareb received over 100 reports of neuropathy related complaints after use of freely available dietary supplements containing vitamin B6.”

We found 30 mg of “vitamin” B6 in our “Ultra Mag” supplement containing 5 forms of magnesium. We thought that “a B vitamin” was not a problem. Maybe it is! The company added it for “heart health”, supposedly, but there is no evidence that B6 supports heart health accoring to the NIH.

“Function
Vitamin B6 must be obtained from the diet because humans cannot synthesize it. “

B6 helps to make B3 from tryptophan.

Deficiency is seen among alcoholics, and people with end stage kidney disease.

Deficiency can manifest as internal mouth sores, or at the corners of the lips.

“Safety
Toxicity
Because adverse effects have only been documented from vitamin B6 supplements and never from food sources, safety concerning only the supplemental form of vitamin B6 (pyridoxine) is discussed. Although vitamin B6 is a water-soluble vitamin and is excreted in the urine, long-term supplementation with very high doses of pyridoxine may result in painful neurological symptoms known as sensory neuropathy. Symptoms include pain and numbness of the extremities and in severe cases, difficulty walking. Sensory neuropathy typically develops at doses of pyridoxine in excess of 1,000 mg per day. However, there have been a few case reports of individuals who developed sensory neuropathies at doses of less than 500 mg daily over a period of months.”

“Because placebo-controlled studies have generally failed to show therapeutic benefits of high doses of pyridoxine, there is little reason to exceed the UL of 100 mg/day.”

In other words, mega doses do not work, and carry risk of nerve damage.

“Can vitamin B6 be harmful?
People almost never get too much vitamin B6 from food or beverages. But taking high levels of vitamin B6 from supplements for a year or longer can cause severe nerve damage, leading people to lose control of their bodily movements. The symptoms usually stop when they stop taking the supplements. Other symptoms of too much vitamin B6 include painful, unsightly skin patches, extreme sensitivity to sunlight, nausea, and heartburn.”

  1. how about niacinamide instead of the niacin?

    Sure, your body can make it.
    It doesn’t mean it does.

    Estrogen and B6 deff direct tryptophan metabolism away from making B3. You can look this up – it’s there.

    B6 deff is more common that what you think – it’s a problem where it is high in blood, but low inside cells. It happens in hypophosphatasia and this is not as rare as the nets have it be.
    It also happens to many that have ill health.
    And no, supplementing doesn’t work for it, because it just ends up piling up more in the blood, and it still doesn’t get into tissues. Correcting your metabolic problem can normalize this distribution.

    Katerina Dalton worked with the UK government to set a limit to B6 supplements, I think it was either 10 or 20 mg a day, a few decades ago, based on her experiences treating women with it. Why did the government decide to change that again in more recent times? I am not sure.

    Same with tryptophan, it was banned as a supplement in the.. 80s. Now it is back on the market…
