I work on my feet all day, and my right knee's been getting weak over the recent years. My physical therapist suggested I should start supplementing collagen and I've been doing that for the past six months or so with significant improvements. A month ago a friend recommend this collagen, she told me how great and delicious it was, but I was very skeptical because I was afraid I could lose my entire progress. However, I decided to give it a try, and I'm so glad I've made that decision! I have not lost any progress, my knee is great, the taste is better than a few others I have tried before and I think I don't feel as tired at work since I've started taking this product (I normally drink it around noon for a snack), possibly because of the mct content. I recommend this brand and collagen in general to anyone who has problems with their knees, joints, etc. It really works!!!I just ordered another jar, almost a month later, so I wanted to post a quick update as I'm now very confident that this product works well for me. I was reading other reviews and I've tried it with bulletproof coffee, makes the coffee taste great, thank you, everyone!
