I recently started taking one tablet a day of vitamin c, cod liver oil, and multivitamins, I never thought you could have too much of that! But my goals on here say that i'm supposed to have 100g of vitamin A and C, whereas these tablets have like 600% of what i need!
So, is it possible to have too many vitamins?

    yes, but not those.
    niacin, pyroxadine, and iron are the worst to over-take and are toxic
    niacin and pyroxadine are known as B vitamins, I can remember exactly their sub number though in the B vitamins.

    It's possible to "overdose" on vitamins. BUT, the supplements you buy over-the-counter are not going to cause you an issue if you're taking them according to the label instructions. If they were going to cause problems, you would need a prescription for them so you would take them only under a doctor's care. Don't worry about it. Don't take more than the label recommends, and otherwise don't sweat it.

    As long as you follow the label you are fine. There are side effect to too much of anything, there is a such thing as "Too much of a good thing". Even water soluble vitamins like C if taken too much can cause rashes. I take a multi, essential omegas and extra C (1000mg) every day.

    Vitamin A is the one you need to watch from those listed...not sure of the dosage but pregnant women or those that could become pregnant need to be extra cautious (hence no liver allowed as the levels are too high) If in doubt ask your pharmacist or Dr

    the RDA for vitamin A is 3,333 IU per day, and very slightly higher for pregnant women

    Make sure you are drinking lots of water if you are taking lots of vitamins.

    I agree with these previous posts. Especially the one about the over the counter vitamins.... Most of the vitamins you will encounter will exit the body through an increased amount of water intake.... I usually double up on my vitamins in the evening (after taking them in the morning) if i have had a big workout at the gym and perspired a lot....

    It is true that anything over 100% is not absorbed by the body. You just pee it out.try to find a multi where none go over 100%

    TO add to this, if you look at the labels on multi-vitamins it will have 200% of some vitamins, 100% of some, 10% of some, etc... and this doesn;t include what you eat.

    If you have ever noticed when start taking vitamins your urine is very yellow (usually a sign on dehydration), but in this case it is just your body getting rid of what it can't use.

    Don't sweat it. Just take them as labeled.

    FYI I would recommend a good multi-vitamin over taking certain ones indivivually.

    in general, vitamin supplements aren't going to give you any where near the amount of usable vitamins anyway, and you shouldn't use them as a replacement for vitamins received through food. The body wasn't designed to absorb vitamins "all at once" and in most cases, you'll receive a percentage of the total listed, in some of the name brand ones, it's a very small percentage. In short, use vitamins as a way to "top off" your vitamins, not fill a large gap.

    Google bio-availability for more information.
