Vitamins of the Stars: Do They Work?

Dec. 18, 2007 — -- Madonna reportedly practices three hours of yoga a day, Gwyneth Paltrow swears by a macrobiotic diet consisting of mostly grains and uncooked vegetables and now Hilary Swank says she pops nearly 45 pills a day to maintain her celebrity physique.

During a recent interview with W Magazine, Swank ran through her supplement regimen, which includes not only tablets but also regular vitamin injections.

"This is my Aloe C, which I dissolve in water," Swank told the magazine, reportedly wielding a large orange pill. "Here's my flax. This one's for my immune system, and this one is my BrainWave. It's great, like if I have a lot of lines to memorize."

Swank is known for her grueling exercise regimen, which includes weight lifting, hiking and martial arts. She has packed on and lost muscle at will for movie roles like her Oscar-winning part in "Million Dollar Baby."

And on the red carpet last week at the premiere of her new film, "P.S. I Love You," the 33-year-old actress looked svelte and glowing in a strapless black dress.

Swank credits her fitness regimen as "one of the secrets to her success," according to W Magazine. But are such extreme measures — pills, potions and even injections — really all that healthy?

Swank insists they are.

"I just took my most important ones, which are my Oz Garcia Longevity Pak," she told W Magazine, describing a, $80-a-month bright-green bottle that includes "brain capsules" and "hormone capsules," among other pills.

"Oz has changed my life," she added. "The Longevity Pak is so awesome."

Garcia, a Manhattan-based self-described "life extension specialist" and often dubbed "nutritionist to the stars," says supplements are a necessity in today's high-pressure world, especially for his celebrity clients.

"She's going from city to city and on and off planes," Garcia told ABC News of Swank, whom he has treated for years and whom he helped get in shape to play a female boxer in 2004. "We've got tremendous demands and obligations. So I work with my clients to teach them how to work in an almost athletic lifestyle."
