Vitamin B overdosage?

Question

I have this energy drink from ASDA.

On the back it says per 250ml 250% RDA of vitamin B6

and 500% of vitamin B12 - over the past two days i've drank 2000ml of this drink.

If i'm calculating this rightly, i've had 2000% RDA of vitamin b12 and 1000% of vitamin B6 each day for two days.

I'm thinking that over intake of vitamin B can cause joint problems, such as premature arthritis (i did A level Biology) but am I in danger from drinking this? or are these variations of vitamin B not harmful?

Answer 1

Answer 2

B6 taken in excess for a prolonged peroid of time can cause nerve damage, so I would not make this a daily habit.

Answer 3

RDA is the recommended daily allowance.  This is the limit below which a  normal person will suffer from vitamin deficiency.  Higher levels of some B vitamins can be beneficial in certain circumstances.  If you overdose with B6 and B12, you'll pee out the excess - but you'll remember your dreams.

Answer 4

symptoms of a vitamin B overdose are normally the following...

Bloating of the stomach

Bleeding Of the nose

Belching

Breathlessness

Bollox swell

Bogey run

and

Bottom itch

Answer 5

Injections are the only way to overdose but even then the body just casts off what it can't use.

Toxicity

No toxic or adverse effects have been associated with large intakes of vitamin B12 from food or supplements in healthy people. Doses as high as 1 mg (1000 mcg) daily by mouth or 1 mg monthly by intramuscular (IM) injection have been used to treat pernicious anemia without significant side effects. When high doses of vitamin B12 are given orally, only a small percentage can be absorbed, which may explain the low toxicity. Because of the low toxicity of vitamin B12, no tolerable upper intake level (UL) was set by the Food and Nutrition Board in 1998 when the RDA was revised (6).

Answer 6

here could be problems with nerves so that the person would not feel the sense of touch very well or might have pain on the skin of the feet or might have problems keeping their balance when walking. There is no need to be supplementing your diet with B vitamins unless you talk to your pediatrician and he or she recommends it because you have a deficiency, or because of another health problem or medication that you are taking. If you have more concerns, you should contact your doctor.

B6 vitamin overdose:

Problems with sense of position and vibration, reduced tendon reflexes, numbness in hands and feet, problems walking, problems with memory, depression, headache and tiredness

Answer 7

Overdose of b6 can give rise to tingling in the fingers and feet, a feeling of being 'not quite there'.

As it is water soluble you will soon excrete it.

vitamin A overdose can make skin go orange and give rise to dizziness.

You should be ok after just 2 days, but do read the label and follow instructions.

Leave the drink alone for a few days!
