Can you take to much of certain vitamins or supplements? Is the body able to only use what it needs and discharge any excess?
If so, is that all vitamins or just certain ones?
Vitamin Overdose?
Vitamin Overdose?
Good question!
I'm not familiar with the effects of excess vitamins so much as I am with herbs. Herbal supplements can and often are, taken in excess and it can effect a body negatively. Vitamins, from what I understand, are flushed out of the system when they exceed what is needed but I have encountered warnings about that so it would be interesting to learn more.

Vitamin Overdose?
here ya go:)Vitamins to Keep a Close Watch On
If you take any of the following dietary supplements, particularly in mega-dose form, or if you take a variety of multivitamins everyday, be careful that you are not exceeding a healthy amount. The Daily Recommended Dietary Allowances and Tolerable Upper Intake Levels listed below are provided only as a guide. Taking supplements in excess of or below these amounts should only be done under the guidance of a knowledgeable health care professional.
1. Iron
Taking too much iron can lead to liver problems, accumulation of fluid in the lungs, fatigue, headache, low blood sugar, coma and testicular problems in men.
Daily Recommended Dietary Allowance (RDA): 8 mg for men, 18 mg for women (8 mg for women 51 and over)
Tolerable Upper Intake Levels (UL) (This is the highest dose adults can take without experiencing adverse effects): 45 mg/day
2. Vitamin A
Excess vitamin A (even at just double the RDA) can increase the risk of birth defects and cause liver damage, reduced bone mineral density (which can lead to osteoporosis), and central nervous system disorders.
RDA: 3,000 IU (International Units) for men, 2,310 IU for women
UL: 10,000 IU/day
3. Vitamin C
Taking large amounts of vitamin C can lead to gastrointestinal upset and diarrhea. There are also reports (that have yet to be confirmed) that it may cause genetic mutations, birth defects, increased oxidative stress, kidney stones and even cancer.
RDA: 90 mg for men, 75 mg for women
UL: 2,000 mg/day
4. Calcium
Though rare, excessively high intakes of calcium can lead to hypercalcemia (elevated levels of calcium in the blood), impaired kidney function and decreased absorption of other minerals, including iron, zinc, magnesium, and phosphorus.
Before taking any dietary supplement, be sure to talk with your doctor. Many of them contain active ingredients that can interact with medications, foods and each other, causing some unwanted (and unexpected) effects.
RDA: 1,000 mg for adults 19-50, 1,200 mg for those 51 and over
UL: 2500 mg/day
5. Vitamin E
Because vitamin E is an anticoagulant, taking too much may increase the risk of bleeding problems. Also, according to the American Heart Association, excess amounts (even 400 IU/day or more) of this vitamin may increase the risk of death.
RDA: 22.5 IU
UL: 1,500 IU/day
6. Vitamin D
When taken in excess, vitamin D can raise blood levels of calcium, which can cause mental changes, such as confusion. It can also result in nausea, vomiting, poor appetite, constipation, weakness, and weight loss.
Adequate Daily Intake (AI) (used when there is not enough scientific evidence available to establish an RDA): 400 IU, 600 IU for those 71 and over
UL: 2,000 IU/day
7. Zinc
A zinc overdose (which can occur from as little as150 to 450 mg/day) can reduce immune function and good cholesterol levels, and alter iron function and copper levels.
RDA: 11 mg for men, 8 mg for women
UL: 40 mg
8. Selenium
In rare instances, too much selenium can result in a condition called selenosis (this occurs when selenium blood levels are greater than 100 µg/dL). Symptoms of selenosis include gastrointestinal upset, hair loss, white blotchy nails, garlic breath odor, fatigue, irritability, and mild nerve damage.
RDA: 55 µg
UL: 400 µg/day
9. Vitamin B6
At high doses (lower than 500 mg per day), vitamin B6 can result in nerve damage to the arms and legs.
RDA: 1.3 mg for those 19-50, 1.7 mg for men 51 and over, 1.5 mg for women 51 and over
UL: 100 mg/day
10. Copper
Taking too much copper can lead to organ damage (liver and kidneys) and neurologic problems. Other symptoms include weakness, abdominal pain, nausea, learning disabilities, memory lapses, diminished concentration, insomnia, seizure, delirium, stuttering and hyperactivity.
RDA: 900 mcg
UL: 10,000 mcg

Vitamin Overdose?
Good information El Guapo as with everything in life "Moderation" is the key. You can overdose on anything if taken to excess.
ALOHA!!
MOTTO TO LIVE BY:
"Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, chocolate in one hand, champagne in the other, body thoroughly used up, totally worn out and screaming.
WOO HOO!!, what a ride!!!"

And that's good advice as well.
Don't OD on Magnesium.
It makes for a very uncomfortable date.

Fat chance.
I conducted an experiment in my lab last night.
I placed one of my usual multi vitamins in a glass and covered it with white vinegar. Thats a close simulation to the stomachs acidity level.
After 1 hr. the pill was minimally dissolved.
Gel capsules do slightly better.
Liquid vitamins just slightly beter than gel capsules.
Spray vitamins (in the mouth) are about 95% absorbed.

The above information is out of date and inaccurate.
This RISK ASSESSMENT FOR VITAMIN D sets out the research up till last May using amounts up to 20,000iu/daily. Also recorded are examples where toxicity has been reported.
In order to produce hypercalcemia in an otherwise healthy adult sufficient vitamin D has to be consumed to raise status to above 350nmol/l.
Each 400iu daily of vitamin D will raise your status 9nmol/l
The average UK adult has a current (December) status of around 40nmol/l
5 x 400iu = 2000iu/daily will almost raise status to 80nmol/l the level associated with a 72% drop in colon cancer incidence and the level at which calcium uptake from diet is maximised.
10 x 400iu=4000iu/daily will raise your status to almost optimal. This level is associated with optimal feelings of well being, lower cancer incidence and maximum muscle strength. (ideal for cancer incidence is 137.5nmol/l)
For those fighting cancer 150nmol/l is the level to aim for. If you look at figures 1 & 2 here you will see how this level provides a stable amount of Calcidiol and optimum stores of D3.
However you would require 7000iu/daily to attain and maintain that level.
So rather than regarding 2000iu as a safe upper limit those wishing to achieve peak physical performance and optimal feelings of well being should be taking 4000iu daily. This should really be considered the Winter RDA with 2000iu being a sensible amount for summer use.

Vitamin Overdose?
An overdose of Iron or vitamin D can be fatal to children. There's also a rare case where a man overdosed on vitamin A when he consumed his sled dog's livers in order to survive in the antarctic.

I simply do not believe it has ever happened.
There is an interesting case of a 2yr old who overdosed on Vitamin D. Where the child consumed2,400,000 IU over 4 days but made a complete recovery.
As the most any child should be taking is 2000iu/daily/D3 the above amount represents 1200 days supply in over 4 days
So if you can name any other substance where a child could consume 3yrs+ daily dosage worth over a few days and still survive I'd like to know what it is.
Certainly if you drank 5 days worth (40glasses) of your daiily healthy intake of water (8glasses daily) in one day you would risk water intoxication so compared with water Vitamin D3 is a whole lot safer.
