New findings have revealed multivitamins are largely ineffective.

A study out of the US examined over 400,000 Americans over 20 years and determined multivitamins didn't help them live longer - and found a link between daily usage and increased mortality.

Nutritionist Nikki Hart says people are spending money on an unnecessary solution. 

"It's like hope in a jar - and I think that's what people are using it for, they think it's magic."
