Too much of a good thing can have unexpected consequences. Just ask people who have gulped gallons of carrot juice, which is rich in beta carotene, only to find that the palms of their hands and the soles of their feet turned a dull yellowy orange.
The carrot-juice syndrome is generally thought to be harmless and reversible, but overdosing on some other vitamins and minerals can have serious side effects.
Vitamin A
Gorging on this vitamin compound in doses of more than 25,000 IUs (five times the RDA) can lead to liver damage, hair loss, blurred vision and headaches.
Bitamin B-6
Ingesting more than 400 mg a day (200 times the RDA) can cause numbness in the mouth and hands and difficulty in walking.
Vitamin C
It was once believed to cause kidney stones, but experts now say there is no solid evidence of dangerous side effects from vitamin C. High doses can produce stomachaches and diarrhea.
Vitamin D
In daily doses of 50,000 IUs (125 times the U.S. RDA), the sunshine vitamin can cause the buildup of calcium deposits that can interfere with the functioning of muscles, including heart tissue. While sunbathing will never create an overdose, taking too many supplements can.
Niacin
Doctors prescribe doses of 2,000 mg (100 times the RDA) to help lower cholesterol. But patients who take that much should be monitored for possible symptoms of jaundice and liver damage.
Iron
Those who want to bolster their red blood cell count, especially elderly people and menstruating women, have been taking iron supplements for years. Daily doses higher than 100 mg (six times the RDA) could interfere with absorption of zinc, a mineral that speeds wound healing and helps regulate the immune system.

Unless you have a rare disease, you should have about 30 units a day and not exceed 800. Lacking a rare disease, you're working on theory with zero evidence to back up the claims about your skin, so you can make up your own answer and be just as right as anybody else. Don't let this dissuade you, though, because the entire vitamin and supplement industry is built on unproven claims.

YES, definitely. If you read the bottle, then it should say the percentage of what you need and how much is in the vitamin. If you take too much or too many, then you might get kidney stones.
You also might start turning gray or something, it happened to my uncle. He was taking a handful of vitamins everyday, and his skin turned gray and he had kidney stones.

Over a period of time your body can accumulate excess amounts of the fat soluble vitamins, especially A and D. These can cause toxic symptoms.
Very large amts of vitamin C may be harmful
Don't forget, many multi-vitamin preparations contain Iron, and you can get Iron toxicity very acutely.
Vitamins are the epitome of the myth, "If a little is good, more is better."

You should stick to the recommended daily dose but it would take an awful lot to give harmful side effects - probably more that you could eat. There's no point overdoing it though as it wornt work better if you take more. Avoind too many "A" vitamins

I think you may mean vitamins.
Yes you can, but it is not the best way to overdose.
I recommend telephoning the Samaritans if you feel so bad about things that you are considering such measures.

if its the b-complex vitamins that is water soluble vitamins you can take as much as you want. since they are water soluble they can be easily excreted in urine.
lipid soluble vitamins (Vit. A,D,E,K) if taken in excess have an adverse effect and may cause poisoning and other side effects
