I dont want you to agree with me Mill,
I just want you to consider... I dont want any body to stop on my account. Just keep an open mind. Im not trying to disway or discourage. Just be conciously aware of how your body reacts to them. Most of all, dont over do it..
An over dose of vitamins actually means intake of those nutrients more than what you need. Vitamins and minerals are needed for your growth and also for the treatment of certain diseases. But the need of these vitamins for your body is not unlimited. There is a certain amount of those nutrients that your body requires. It is necessary to fulfill that required amount. But if you exceed the limit, you will be harming yourself. Thats all Im saying..If you exceed then organs could get over worked. So I didnt make my previous point clear, my fault..
Vitamin C was believed to be a safe vitamin that is not dangerous when taken as over dose. But recently researches have shown that too much intake of vitamin C can lead to develop diarrhea.

On the other hand you need just a little amount of vitamin B6. The required amount is only one or two milligrams per day. So you need to take only one tablet in two days. If you take greater amount of vitamin B6, it may cause you great harms like, sensory control loss and motor control loss.
Again, the adequate amount of vitamin B6 that your body needs is one hundred to three hundred milligrams per day. If the amount is increased in your body the outcome may be very dangerous. An over dose of this vitamin can cause various bad effects such as blood clot, fatigue and other reproductive disorders.
If you do not know the consequences of over doses of vitamin A and vitamin D and intake these two vitamins as you do in case of vitamin C, you are doing another great mistake. Excessive amount of vitamin C can be passed through the kidneys. But the excessive amount of vitamins A and D remain stored in your body. It is generally stored in the liver and also in the fat. And this can cause dangerous results such as making your skin dry and itchy, fatigue and also cirrhosis of the liver.
Vitamin considerations should be evaluated on a case-by-case basis because one person may have high iron levels and should not be taking supplements containing iron, while another person with kidney stones caused by calcium would not want to take a supplement with calcium. Understand my point? "Many supplements out there don't go through the process of being tested because it is expensive," and with these vitamins, you don't know if you are getting what they say and you don't know if you are able to absorb it in the base they put it in."
Just be careful before taking mega doses of vitamins and also support for a general awareness relating to the growing problem of consuming extra doses of medicines specially the high power mega-vitamins.
My bottom line:
If you have an ailment of some kind perhaps Kidney stones, you could be adding to a problem that you did not know it was there! What is healthy in over dose or high doses can be toxic for the Kidneys..
The kidney is filter and with increased filtration it will work more than it should.
Just watch and regulate, be carefull and pay attention to how your body reacts..
