5 celebrities who invest in natural products

Fabio, Healthy Planet Vitamins

Could whey protein be the secret to Fabio's youthful appearance and flowing locks? Fabio Lanzoni is the president and founder of Healthy Planet Vitamins, which sells whey protein, glutamine and colostrum products. The company claims its products will "revitalize your inner youth, build healthy lean muscle, re-establish immune system strength and delay the effects of aging."

Fabio is pictured here at Natural Products Expo West looking decidedly youthful.

Mark Wahlberg, AquaHydrate

Actor Mark Wahlberg (also fondly known as Marky Mark) is a foundation shareholder and on the board of AquaHydrate, a purified, alkaline water enhanced with electrolytes and trace minerals.

The Oscar-nominated actor first used AquaHydrate while training for the film "The Fighter." "I drink it until I go to sleep," said Wahlberg. "That's all I drink. That's all my kids drink," he said at the IZOD Indy 500 Hollywood event this year, noting that he's usually not one to endorse a product.

Olivia Newton-John, Amazon Herb Co.

If you're around Olivia Newton-John and it's lunch time, chances are she'll share her Digestazon digestive enzymes with you, courtesy of her husband John Easterling's business, the Amazon Herb Co. The company offers dietary supplements made from rainforest botanicals and also provides assistance to indigenous communities to help secure a sustainable future for the Peruvian rainforest. That's one powerful digestive enzyme!

Newton-John's recent performances have been to promote her husband's products or raise funds for charities.

Apolo Ohno, 8Zone

Before entering his third Olympics, eight-time Olympic champion and short track speed skater Apolo Ohno founded 8Zone. 8Zone is a three-step weight loss dietary supplements system taken in eight hour increments to support activity, sleep and downtime. Two capsules are taken at the start of three zones, patriotically called the Red, White and Blue Zones.

The system retails for $100, which is a few hundred dollars less than some top-notch speed skates—and significantly easier to use.

Demi Moore, HAPPYFAMILY

HAPPYFAMILY, a premium organic baby and toddler food brand, has star-studded support from Demi Moore, who joined as a private investor during the company's second round of financing. The five-year-old company also added chef and restauranteur Tom Colicchio, Spanx founder Sara Blakely and Twilight producer Guy Oseary to its supporters this year.

Moore isn't new to the industry. We reported earlier this year how she tweeted about doing the Master Cleanse with husband Ashton Kutcher. Last year, Moore also invested in Vita Coco coconut water at Oseary's suggestion.
