It’s a great story.

Natalie Kather, MD; double board certified in Family Medicine and Anti-aging, and her husband, world-renowned biochemist, Stephen Cherniske.

They retire from clinical medicine and research, and start looking for their next challenge. Like all dog lovers, Stephen and Natalie have struggled with the pain and suffering that often befalls dogs, most often after age 7, but sometimes much earlier.  So it was natural for them to turn their training and experience towards developing a comprehensive anti-aging program for dogs.

“We are “infomaniacs,” says Dr. Kather, “always looking for effective ways to improve quality of life.” At the top of their list?  Alleviating pain. Kather explains that most pain is caused by inflammation, and while she and her veterinarian colleagues have plenty of drugs at their disposal, many of those can have serious adverse side effects. “Stephen spent 15 years researching plant-based anti-inflammatory compounds,” explains Dr. Kather. “Using genomics and high-throughput screening, his group was able to create products with efficacy that was as good or better than commonly used pain-killers. In one clinical trial with dogs, Stephen’s plant-based compound was shown to be twice as effective as the leading glucosamine and chondroitin product. Most important, these results were published in a peer-reviewed biomedical journal. As a physician, I need that kind of gold-standard scientific support.”

It gets better

Searching the veterinarian journals, Dr. Kather found studies showing that DHEA had anti-aging benefits when given to dogs. “Most people know that my husband is one of the world’s foremost experts on DHEA,” notes Kather. “His book, The DHEA Breakthrough (Random House, 1996) was an international best-seller, and together with his 2003 sequel, The Metabolic Plan, reached over 1.5 million people. DHEA is a protein produced by the adrenal glands and brain. It is considered to be the body’s most comprehensive repair signal. Importantly, levels decline with advancing age in both humans and dogs, contributing to age-related degeneration. We were both excited to see research showing that dogs – just like humans – can benefit from supplemental DHEA.”

Further research found studies showing benefits for hydrolyzed collagen, and antioxidants derived from aronia berry.  The final formulation, called RenuVite4Dogs, combines all these ingredients, and according to Kather and Cherniske, is the only research-proven anti-aging product for dogs.

Does it work? “Ask any of the thousands of very happy customers,” says Dr. Kather. “Or go to and look at some of the photos and videos of dogs that got a new lease on life, with greater energy and mobility.”  Adds Cherniske, “it’s also telling that our biggest customers are veterinarians, who tell us that they’ve never seen results like this. Vets can place wholesale orders and dispense RenuVite4Dogs at their clinics.”
