Can vitamins be too much

I love taking vitamins. I currently consume about 5 types of Vitamins every day but my friends have advised me to reduce them because they believe that too many vitamins can have side effects. Kindly advise me.

Although consumers are bombarded with announcements that taking high doses of certain vitamins can benefit health in many ways, however, taking too much of some nutrients can be dangerous. While water-soluble vitamins are readily excreted from the body and not easily stored in tissues, the fat soluble ones are not. Some of the water-soluble vitamins include vitamin C, plus eight B vitamins (B1 to B8).

Because water-soluble vitamins aren’t stored but rather excreted through urine, they’re less likely to cause issues even when taken in high doses. However, taking megadoses of some water-soluble vitamins can lead to potentially dangerous side effects. For example, taking very high doses of vitamin B6 can lead to potentially irreversible nerve damage over time, while taking large amounts of niacin — typically in excess of 2 grams per day — can cause liver damage. Unlike water-soluble vitamins, fat-soluble vitamins do not dissolve in water and are easily stored in your body’s tissues.

There are four fat-soluble vitamins: Vitamin A, D, E and K. Given that fat-soluble vitamins can accumulate in the body, these nutrients are more likely to lead to toxicity than water-soluble vitamins. While rare, taking too much vitamin A, D, or E can lead to potentially harmful side effects.
