It depends on the lifestyle and environment a person is exposed to. For a person who is working or studying, he/she spends a large portion of time out of home. Most of the time, the choice of food depends on the availability of healthy food from the vendors.
Unless a person is actively searching for healthy food, he/she cannot be certain that the food they eat while at work or in school is healthy, and contains the required vitamins and nutrients.
Therefore, taking vitamins and supplements is a personal choice, unless a need arises due to medical concerns.
There is no right age to start taking supplements. My 2-year-old is already taking Vitamin C, with his older brothers.
Lastly, yes, there is a chance of over supplementation, but in these cases, the doses have to be really huge to cause any damage as our bodies are more resilient than we think.
