Stem cell scientist · Co-founder of PetREGEN®

Formulated by the scientist who studied the ingredients.

Christian Drapeau, MSc, is internationally recognized as a pioneer of plant-based adult stem cell nutrition and wrote the bestselling book Cracking the Stem Cell Code. He created the first human stem cell-support formula. PetREGEN® brings that work to dogs and cats, and Drapeau is a named co-author on 4 of the 7 peer-reviewed references behind its ingredients.

He built PetREGEN® as Regenerative Nutrition for pets: whole-body, science-based nutrition designed to support natural stem cell activity, formulated to trigger a release of stem cells within 2–3 hours of a meal.

“I recommend PetREGEN… a game changer in bringing back the health and vitality of many pets.”

Meet “Dr. Zoolittle”

Penny Wood, BSc, is an animal health and longevity zoologist, known to pet parents as “Dr. Zoolittle.” Here's what she tells them to expect once PetREGEN® joins the daily bowl.

“We're working at the cellular level of the body. It's not just a band-aid on the surface.”

Penny Wood (“Dr. Zoolittle”)

✓Early on: better overall condition, coat texture, energy levels and that sparkle in their eye.

✓As it builds: more noticeable changes as the body's own stem cells get to work.

✓Whole body: “It's going to work across the whole board,” in her words.

Torn CCL

Featured story

Boosie's recovery story

From struggling to walk to playing again.

Boosie, a 6-year-old Rottweiler, was diagnosed with a torn CCL (similar to the ACL in humans) and was unable to walk or play for weeks. While waiting for veterinary care, his pet parent added PetREGEN® to his daily routine.

“Within 2 months, Boosie started walking and playing with other dogs at the park.”
