Marine collagen is also especially rich in the amino acid hydroxyproline, which is an essential component of skin, blood vessel walls, and other connective tissues. Additionally, bovine and porcine products often come from farmed animals exposed to hormones and antibiotics making any byproduts run the risk of said exposure. Some countries have cattle graze on grass all year long and are not treated with artificial growth hormones or excessive antibiotics, making this an excellent developing alternative for consumers.

    I have been taking Collagen-Flex for over 5 years and I really credit this product for the flexibility and energy it gives me to accomplish the busy schedule that I adhere to. I am retired and way over 65. I do my own yard work, do yoga every day, and keep up with my very energetic Labrador Retrievers. Do yourself a favor and keep moving!

  • Smooth Recovery

    I received shoulder surgery recently and recovery has been painstakingly slow. The pain continued into physical therapy and I wanted to try supplements to help speed up the recovery. After tons of research, I found liquid collagen to be the solution for helping my body repair itself. After taking liquid collagen twice a day, by week 2 I noticed a substantial increase in mobility and a decrease in pain. I went with Intenergy's Collagen Flex since it was the bang for buck and the results speak for itself. I plan to continue using this supplement throughout my recovery and my physical therapist is now recommending this product to future patients after seeing my results!
