Dean Karnazes

Ultramarathon Man

I'm Dean Karnazes, the Ultramarathon Man. I've run 50 marathons in 50 states in 50 straight days, won the 135-Mile Badwater Ultramarathon, and run for three straight days without stopping. That means I count on my joints to keep me moving.

I am now sponsored by Joint Juice®, but I've been a user for a long time. I was introduced to Joint Juice® supplement drink when it first came out by Dr. Kevin Stone, the founder. He told me about it and I've been using it ever since.

Simply put, glucosamine works for joint health. Numerous studies have shown the benefits and when I push my body to the extremes I've found the liquid form in Joint Juice® products to be most efficacious. People ask me how I recover so quickly and stay on the road, well, it's good conditioning, cross-training, and strong joints. Using Joint Juice® products makes a difference and allows me to continue pushing the envelope.
