Are they safe and do they work?

The story of a man who has ended up in a transplant after taking green tea capsules. What are some of the dangers of supplements and what are the health benefits?

When Jim McCants started taking green tea pills he had hoped he was giving his health a shot in the arm.

Instead, it appears the pills that require such an urgent transplant.

Experts point out that experiences like that of Mr McCants, are "extremely unusual".

In the UK, supplements are subject to EU regulations on their safety and health claims.

But Dr. Wayne Carter, from the University of Nottingham, says it's wrong to assume that food supplements do not have the potential to be harmful.

If you take supplements in quantities above recommended levels there are risks.

While in many cases excess levels of excreted, there is the potential for it to be toxic, particularly to the liver, which detoxifies the substances we consume.

"I think sometimes the idea that people will be good for me, so it will be even better," Dr. Carter says.

"This is not without risk."
