most vitamins are not dissolved in water.\nSince Vitamins C can be dissolved by water, you can take a lot.\nNo, is not unlimited.\nEverything you can have TOO MUCH.\n\nToo much water can kill you, because it lower the Na and K in you blood too much and your heart will stop.\n4 to 5 gallons of water within 2 days in too much.\n\nMost vitamins, such as A,B,D,E, etc. is not dissloved by water ,but by oil.  So they get stuck in your body longer.  So is easier to have too much of these vitamins.\n\nDont over do anything, it is a simple rule to live by.

All vitamins should be taken with a meal.  Don't overdo E.  The super B will contain B-12 so you may want to space those out.  Be careful with doseages!

Lots of studies are showing you can over do it with vitamins.  Any over the counter multi-vitamin should be fine but there's no need to get carried away with it.  Eat the right things and you don't need them at all.  By the way, always eat to digest vitamins or most of them won't have time to get into your body before they're gone.

Go to Barnes & Noble and get a book called "the Vitamin Bible." It's only 7.95, I use mine all the time! It tells you what every vitamin does, how much your body can absorb at a time, where to get it in natural foods, it just tells you so much. You can also look things up by sympton like "bad skin" and it will tell you what to take.

Your body is like a dam when it comes to vitamins. First you have to fill it, then everything runs over the top or through it in the case of your body.  It is said that in America we have the most expensive urine in the world. This is becasuse of all the vitamin supplements we consume.  Make sure to drink lots of water with the vitamins you take.  Our bodies are 70% water. Not 70% coffee or 70% cola.

Yes you can.\n\n".Effects (of taking too much Vit C. include: renal colic (ie, nephrolithiasis), diarrhea, nausea, rebound scurvy in infants born to women taking high doses, hemolysis if G-6-PD deficiency is present, possible dental decalcification, and increased estrogen levels."\n\nWe get vit. C from these foods in our diet: Food sources : Apples, asparagus, berries, broccoli, cabbage, melon (cantaloupe, honeydew, watermelon), cauliflower, citrus fruits (lemons, oranges), fortified breads/grains/cereal, kale, kiwi, potatoes, spinach, tomatoes. \n\nDietary Reference Intakes (DRIs) : The recommended daily intake for Vit. C by the U.S. Food and Nutrition Board of the institute of Medicine for men older than 18-years-old is 90 mg/day; for women older than 18-years-old is 75 mg/day; for pregnant women older than 18-years-old is 85 mg/day; for breastfeeding women older than 18-years-old is 120 mg/day. Recently, some experts have questioned whether the recommended daily intake should be raised. Others have recommended higher intake in some individuals, such as smokers, in whom an additional 35 mg/day has been recommended by some.

Yes.  Taking too much of anything can hurt your body.  There are two types of vitamins: water-soluble vitamins and fat-soluble vitamins.  If the vitamin is water-soluble (e.g. vitamin C), it would take a lot of it to hurt your body, because it dissolves in water and will be excreted during urination.  However, if the vitamin is fat-soluble, it will be absorbed into your fat and remain in your body for a while.  Too much of a fat-soluble vitamin will be toxic.  That's why you should follow the "percentage of recommended daily intake" label on the side of the bottle.

If you take too much B12, you will lose what you don't need through urinating.  The only vitamins that can be dangerous to mega-dose on are A, D, E and K.  Those four vitamins are fat soluble, and do not leave your body when you take a mega-dose.  So, you are safe.

There's a GREAT source of information about vitamins at\n\nhttp://www.intelihealth.com/IH/ihtIH/WSIHW000/35320/35323/442717.html?d=dmtHMSContent\n\nIt describes different kinds of vitamins, when they are necessary--and this site goes beyond the usual "pregnant women should take a prenatal vitamin" advice that other sites give.\n\nThere is even more information at\nhttp://www.virtualhealthinfo.com/news_vitamins.shtml\n\nI remember hearing a few weeks ago on NPR that for the first time, a daily multivitamin was recommended for people, even those who eat a pretty normal diet because the nutritional value of the foods we eat is no longer as good as it used to be.  I suppose this is why we can get tomatoes that may not taste like much, but which travel to market without damage.  \nI looked for an article on this, but I couldn't find it.  (Sorry.)

Well I would wonder how many over the amount you take? Some is alright. I think the ones I take say 8 per day, my doctor says 2 per hour, all day if needed. The first two answers make no sense to me. The only way you would throw up is by having toooooooo many(like a full bottle or more) as for the other well, gee whiz any food or supplement will do that.... Talk with your doctor if you find you need more than the bottle directs, as it could be something else that needs attention. Good Luck

The craze over vitamin C's power to prevent and treat colds started with the Nobel Prize-winning chemist Linus Pauling's 1970 book Vitamin C and the Common Cold. Pauling advised taking 3,200 to 12,000 milligrams per day, far higher than conventional standards. The latest recommendation from the Institute of Medicine is 75 milligrams per day for women and 90 for men, with an extra 35 milligrams daily for smokers, who suffer higher levels of oxidative stress and cellular damage. This is a far cry from Pauling's original proposals. And studies testing Pauling's cold theory indicate that vitamin C probably does not prevent colds but may make them milder and shorten their duration.

Interestingly enough...to add to ur findings...I have been told by my family doctor that most people do not need a vitamin if they are healthy adults who eat right.  And I have personally never been able to take centrum because it would always make my stomach sick.  I'm checking out that site now.

Looking at your conditions, maybe you might want to try nutritional therapy to replenish your cells with the essential 46 vitamins. \n\nMy grandmother, 76 years old, who has been a diabetic patient for many years, and she is taking Spirulina (Certified Organic by Japan Health Food Association), and when the doctor diagnosed her, her blood sugar has dropped to normal level and she is feeling more energetic than last time.\n\nThe human requires 46 essential nutrients from the daily diet. Essential vitamins consist of vitamins, minerals, proteins (amino acids).\n\nEssential nutrients:\n\n1)Most are not produced by the body. ->100% sourced from our diet\n2)Many are broken down, lost or excreted daily. -> Required daily\n3)Should be consumed in balanced proportions.\n ->Nutritional intake should be balanced.\n4)Are interdependent and may not be able to function without the presence of others. -> The 46 essential nutrients should be presented at all times. \n\nLacking of 46 essential nutrients, Acidic body condition, unhealthy lifestyle will lead to unhealthy cells  Semi unhealthy state – headache, fatigue, shoulders ache  Long term will lead to high blood pressure, diabetes, cancer, leukemia, many 21st century common diseases.\n\nIf you want to know more information, you can email me at jaslinlee@yahoo.com I will glad to answer your enquiries.
