Why I Created MD1
From the Clinic to Your Dog’s Bowl As a veterinarian, I’ve seen how the right nutrients can transform a dog’s health — brighter eyes, smoother movement, better digestion, calmer moods. But to get those results, I often had to send pet parents home with five or six different supplements. It wasn’t practical. MD1 is the supplement I always wished existed: one formula that combines high-quality ingredients in the right doses, designed to work synergistically. Built on an integrative philosophy — blending conventional science with holistic wisdom — MD1 supports the body’s natural intelligence while protecting against the wear and tear of modern life. The result? Simple, sustainable, effective wellness — so your dog can live not just longer, but better.
— Dr. Jenna Lenarz, Chief Veterinary Officer
