b6 can cause alot more than depression.
it can cause irreversible nerve damage.
from personal experience, be careful how much you take.
100mg-200mg daily for me caused some very disturbing symptoms.
numbness, tingling, pricks/pins/needles, shocks, buzzing/vibrating, muscle twitches, muscle weakness, severe fatigue, diziness, lighheadedness, anxiety, irritability etc.
was diagnosed with b6 toxicity recently. beware of b6. it is a dangerous "water-soluble" vitamin.
I recently had my vitamins and minerals checked and all were within range except for B6 which was 558 nmol/L (range 30-110 nmol/L). I was on a b complex (50mg b6) and multivitamin on and off for alot of last year just on days I felt a bit run down. When I got really ill last October I was pretty much taking my multi b (50mg b6) and multivitamin (25mg b6) every day up until I got my b6 result a couple of weeks ago.
Hi,
Regarding vitamin B6, a water soluble vitamin is essential for the normal and optimal functioning of the body. The Recommended Dietary Allowance (RDA) is the average daily dietary intake level that is sufficient to meet the nutrient requirements.
RDAs for vitamin B6 (in milligrams), are: 1.3 mg for men and women under age 50; 1.7 mg for men and 1.5 mg for women over the age of 50, 1.9 mg for pregnant women, and 2 mg for women who are breastfeeding.
7mm and 13mm. He took chemo: Folfox, Avastin, Oxaliplatin, and Xeloda until April 2008. The April CT scan revealed that the tumors had grown slightly and that there were four more small nodules visable. He discontinued Chemo and chose alternataive therapy with High Dose Vitamin C, and B17, changed his diet, and had some blood boosters. In August a new CT showed the good news that no new tumors were visable, but that the primary tumors were slightly larger.
I have been reading the posts on Vitamin b6 toxicity. I started having the pins and needles 6 months ago. My neurologist did a B6 test and my B^ level was 1400. I take no vitamins with b6 in them only Calcium and B3. I checked to make sure there was no B6. Since then it has fluxuated with the lowest being 285. I had a blood test last week and it is back up to 1000. Do you have any ideas of what to do next. My neurologist suggested that maybe I should see a endrocronologist.
My body smply could not tolerate the drug and while taking Xeloda I lost more than one pound per day, snd had relentless nausea and terrible pain in my hands and feet. After one three-week cycle my doctor discontinued the Xeloda. I was able to complete treatment with the oxiliplatin. This was in 2004 and I am cancer free today. Ask your mother's doctor for something else. If possible she should not stop chemo until her doctor is certain no trace of cancer remains in her lymph system.
Thyroid UK - The Role of Vitamins in Thyroid Deficiency
The Tolerable Upper Intake Level (all sources both diet and supplements) for vitamin B6 is 100 mg daily. The first major report of vitamin B6 toxicity appeared in the early 1980's. Until then, scientists believed vitamin B6 was like other water soluble vitamins and can could not be toxic. The reports of neurological damage were after taking 200mcg of vitamin B6 daily for two months or more.
Did you learn this from your doctor? Just wondering because one would think the doc would have something to say about this. If you look at the archives of MedHelp on this and other sites there are some very long threads about B6 neuropathy, which is the main concern some suffer when taking large amount of it. They generally speak of nerve pain, but there are other possible symptoms. Are you supplementing with it?
Vitamin B6 is found naturally in our foods, however, B6 supplements are the main reason for toxicity of vitamin B6. Long term (2+ years) supplementation of 500-5,000mg/day will result in medical issues, such as neuropathy which maybe reversible with discontinuing the supplement and lowering high B6 foods. The recommended daily dose is 1.3mg for men & women ages 19-50 and 1.7 for men >50 years old.
i've read on the internet that deficiency of vitamin B1 B3 B6 and B12 might make worse the feeling of anxiety and stress. does anyone know if these vitamins will help with this feelings of anxiety and stress?
Hi there,
Vitamin B-6 is essential for maintaining healthy nerves and muscle cells and is useful in the production of DNA and RNA. Vitamin B6 dietary allowance is 2 mg and toxicity may occur on taking 100 mg daily.Headaches, mood changes, severe fatigue, nerve damage are few common side effects reported. There is no prescribed treatment for vitamin b6 toxicity. You may limit the intake of foods and supplements rich in this vitamin to overcome the condition.
Yes I've heard the vitamin b6 and unisom help and it did. Just wondering if it worked for some and then stopped working?
It is recommended not to take any supplement of vitamin B6 and try not to eat large amounts of foods high in vitamin B6 at meals for 6 months. Vitamin B6 food sources are whole grains, legumes (beans), nuts, meats, and poultry and the sources with lowest amounts are: Peaches, Milk, Peas, Carrots, Ground Beef, Brown Rice, Soybeans, Avocado, Banana, and Turkey. It is a required vitamin and is needed in numerous necessary processes in our bodies. Eat with caution and small amounts.
I have, too, been experiencing all of the symptoms. I stopped B6 (synthetic forms) about a month ago and my symptoms are getting WORSE. However, I've heard that that is possible.
Now here is the tricky part -- does anyone else's symptoms exacerbate IMMENSELY after eating and then peak up in the afternoon??
Any insight is helpful, thanks!!
There is a condition called B12 anemia. I don't think you're that low, but the way to do this is to eat better, for starters. If you're a vegetarian, that explains the B12 shortage -- it's found largely in animal food. And make sure your supplement is the methylcobalamin form, not the cyanocobalamin form -- the methyl form is much more absorbable. Also, taking a sublingual will absorb better and more quickly, and you can take a whole lot more than 50mcg.
Saw a neurologist, had full MRIs, Echo, and blood work and the only thing that came up was high b6 at almost twice the upper limit. The thing is that most of my symptoms are on the right side of my body, so the neurologist is skeptical about the b6 toxicity diagnosis. The symptoms are:
- right foot feels tingly and there is a strange nerve sensation on the outside of my right leg.
