I love so much about this collagen. I have tried a few now but this has by far made the biggest positive impact. The refillable jar is a bonus, the requirement for less quantity due to the powerful nature of the ingredients is perfect. There is no smell or taste so your morning drink is not tainted at all. No more knee pain! My nails are growing and strengthening by the day. My hair has grown past its normal ‘stop zone’ which excites me, I also have so much more hair!! My skin really took a hit when my sister passed away suddenly - I looked saggy, loose with deep wrinkles. The colour seemed almost grey. The only change I have implemented is using this collagen. I love love love this product and shout it from the roof tops. I’ve added a before and after of how my appearance has changed.
