I am an ex-dancer with lots of ligament & tendon injuries. This collagen has been a great tool for my recovery. And it's really reasonably priced. Also, it has made my hair and nails grow faster. Bonus!

I'm a neuroscientist and research is my background. I researched not only collagen, but I asked Dr. Doug a ton of questions when I was visiting his office. Next I tried the product and I'm very, very happy. Great product. Outstanding formula. Congratulations.

Collagen product from Dr. Doug has really made a difference with my skin the most. I feel it has turned back the clock and my skin is clean, tight, healthy, and blemish free. It is the best longevity secret. I also love that I don't have to drink some disgusting concoction to get it in my body. Great Product!!

I've been aware of Collagen as a natural supplement that we should all take for longevity. It helps so many things in the body. Hair, skin, nails, cellular health. Muscle and Joints, etc. I've been taking Dr. Doug's Collagen formula for 8 weeks and I can really see a difference in my skin, my joints after exercise. And most surprising is my ability to recover from muscle soreness. Highly Recommend!!

Amazing service, prompt with delivery will be buying from them again
