How Vitamin B6 Affects You

Vitamin B6 is vital to normal body function as it is involved in starting reactions involving substances called amino acids. It is a real team player as well. When processed in combination with vitamin B12 and folic acid, B6 can help prevent and fight heart disease as it can help to process homocysteine, a substance often associated with various cardiovascular problems.

It is quite rare for a person to have Vitamin B6 deficiency because it is a vitamin that is present in just about every food. In a sense, you’d have to work very hard to be deficient in it or have an underlying problem present that prevents your body from absorbing the vitamin properly.

Some things that can cause a person to absorb vitamin B6 insufficiently include:

  • Alcoholism
  • Persistent diarrhea
  • Starvation
  • Genetic disorders
  • Drug interactions

An interesting potential cause of vitamin B6 deficiency may be the use of contraceptive drugs. These drugs disturb the trytophan metabolism and can potentially create a B6 deficiency.

Also, a disease called pyroluria may actually be caused by B6 deficiency. This is where it gets serious because pyroluria carries among its symptoms mental problems and even schizophrenia.

The signs and symptoms of a deficient amount of vitamin B6 in the body can be all over the map, really. However, some people that suffer from this condition have symptoms like:

  • Insomnia
  • Irritability
  • Weakness
  • Paranoia
  • Depression
  • Anxiety
  • Lack of sex drive
  • Water retention
  • Rapid weight gain or loss
  • Problems with processing sugars
  • Problems walking
  • Cracked skin at the corners of the mouth

When present in infants, B6 deficiency can manifest itself through

  • Irritability
  • Seizures
  • Stunted growth

Studies have shown that the taking of dietary supplements may reduce a person’s risk of developing Parkinson’s disease by up to half. However, taking too many supplements could cause vitamin B6 toxicity, which has been shown to cause neurological problems, particularly pain.

Luckily for most people, vitamin B6 deficiency is fairly easy to prevent and treat. All you need to do is eat a balanced diet or take B6 supplements. If you have an underlying condition that may be preventing you from processing B6 properly, then treatment of these conditions should eliminate the problem. As always, see your doctor to make sure you have this deficiency before taking supplements or doing anything drastic. At home detection tests are meant to help you figure out if you have a problem and then seek the appropriate treatment, not to treat yourself.

    I’ve been told that increased Vitamin B6 supplements can help reduce the symptoms of tendinitis (“trigger fingers”). Is this true?

    The information given here is very informative for the lay person,as many do not know about the ins and outs of the needs of the human body,as all we know and are told by the medical profession is what is wrong and what drugs and medications they are going to describe ( prescriptions ) that you have to use or go onto Thank you Regards Thomas

    Another cause of significant B-6 deficiency is a too little known condition called Pyroluria. This is a genetic blood abnormality resulting in very low B-6 and Zinc, among other things. Many people with mental illnesses and conditions also have Pyroluria.

    The medical establishment doesn’t recognize the condition, and there is no known cure, but mega doses of the proper amounts of deficient nutrients has amazing results.

    i have been vit b6 def for many years but have learned to keep it under control with b6 suppliments. If i don’t take the b6 i get bad cracks in the corners of my mouth that are painful. within 48-hrs of taking the b6 the cracks will be gone.
    discovered this on my own after many visits to the dr about the cracks in the corner of my mouth and found the answer thru research.

    Cracks in the corners of your mouth could also be from folic acid deficiency. Folic acid deficiency can cause all-around malabsorbtion of all nutrients. Niacin deficiency can cause lack of stomach acid, which would make it harder to digetst proteins to get B vitamins. Just take a multi-vitamin. They usually have decent amounts, but may contain a little too much Vitamin D.

    I stopped smoking and drinking more than 2 years now. I definitely quit smoking. But I just started having a glass of wine or beer occasionally. The day I stopped smoking, I went on a strict dieting. But, I started suffering from gastritis to acute one. I experienced a sort of transformation happening in me and I was very uncomfortable. I also developed panic attacks. I went to the doctor several times and i was prescribed Nexium 40mg, xanor etc..I still felt very abnormal. I started fearing that I might be having something else. I was stressed, anxious, and could not tolerate any stressful conditions. I felt like suffocating in very stressful situation. I knew something was wrong somewhere. All the times I went to see the doctor, he prescribed me with more or less the same drugs. I could not concentrate properly, I had running minds, and my vision was not working at its best. Two days back I went to the doctor again, as I had to face some stressful situations haunting my mind. He prescribed me with lexotanil that I’m not taking. But, he, for the very first time, prescribed me some vitamins B6. And that was the miracle! After two days taking my B6 twice daily, I could see the a dramatic change and was feeling like I got my complete health back. I was Vitamin B6 deficient. I hope that my health continues to be as healthy as possible.
