I have been on Collagen Plus a few weeks. I have seen a dramatic change in my skin. I no longer get the big red and purple bruises when I knock into something. I live in the desert southwest, the air is very dry. My skin requires moisturizer daily. I discovered that Collagen Plus has help my skin retain moisture. So, no “old lady” bruises and softer skin. Yea! If this bio nutrient is improving my outside, I am sure it is working well for the inside of my body! I love it. I put it in my morning coffee, it dissolves instantly.
