For Shinamae, I've had multivits for years, Boots have perfectly decent range, but you do NOT need the ones labelled 'Senior', and beware of any with 'extra Iron'.
I do prefer to get those with the recommended dosage of Selenium, which I read somewhere is a key mineral (sorry, forgotten why!).
For those saying a "balanced diet" is fine, well, yes it's good, but one multivit a day isn't overdoing things, and may just make up for something you've missed?
I ALSO take a garlic cap every day, ( better if it's odourless!), helps ward off colds and flu for some people (and I don't get many colds, famous last words).
