Simon Cowell Takes Vitamins Intravenously

Simon Cowell's daily routine is full of ways to keep himself looking and feeling young. Of that routine, the most bizarre anti-aging practice is probably his method of taking vitamins -- intravenously. 

"It's an incredibly warm feeling... You feel all the vitamins going through you. It's very calming," Cowell said.

Ursula Arens, a dietitian at the British Dietetic Association, says taking vitamins intravenously really doesn't make much of a difference. 

"The absorption of vitamins is very efficient so – apart from people who are very ill or have particular gut problems – nearly all of what you eat is taken up by your body," she said. "If you are worried about not getting enough vitamins from food, and cannot change your diet, then vitamin supplements are a simple way to give you reassurance."

Cowell anti-aging regimen also includes smoothies and ginger tea.
