GNC Holdings has launched its new Marked line of nutrition products, developed in partnership with Mark Wahlberg.

Wahlberg worked with leading GNC scientists and wellness experts to develop the line of performance nutrition products and will also serve as brand ambassador.

"Much of my success can be attributed to my dedication and hard work. …I'm committed to living a healthy and productive life and helping the people around me do the same," says Wahlberg. "That's why I teamed up with GNC, a brand I trust for quality and integrity, to develop Marked, and I'm proud the line will contribute to my foundation that supports inner city youth."

Marked products include a daily multivitamin pack, pre-workout igniter, protein bar and protein drink. A portion of all sales will benefit the Mark Wahlberg Youth Foundation.

Marked is now available in GNC stores across the U.S. and will be expanded to other retailers and countries later this year.
