In an ideal world, we'd all eat perfectly and we'd always get all the vitamins we need. However, that's not always possible, especially for the super-busy Heidi Klum. Still, she makes sure she gets her vitamins. Or, rather, her trainer makes sure she does.

Klum works out with David Kirsch, who also trains celebs like Naomi Campbell and Anne Hathaway, and he ships her cases of his Super Juice packets, which, when added to water, add just 30 calories but provide your daily vitamins. He also provides his clients with Thermo Bubbles, which is supposed to boost energy and metabolism.

How about you? Do you rely on supplements to get what your body needs, or do you get it all through your food?
