Bests & Worsts Reviews from Amazon

I started mixing this collagen with my protein shake each morning. All of a sudden I began to feel many different symptoms kind of arriving at the same time. Thinking that the only thing different in my diet or routine was this powder I stopped taking it. I felt better within a week of stopping it. Now let me tell you I was SICK. I am an otherwise healthy 65 yr old female who competes in horse show jumping. I first noticed blurred vision. Went to my opthamologist to see if my RX had changed. It had not. A week later I started feeling lightheadedness, shortness of breath, fatigue and indigestion for about a week. Checked with my Cardio and all was well. So what the? Now it's 2 weeks of feeling really crappy indigestion so much so that I was moaning really bad fatigue. Had carotid ultra sound, stress test, echocardiagram and thinking about seeing a pulmonologist. Then I stop taking the Dr Axe. Viola. One week later all better. Now this gets very good reviews and I'm sure it works for some people. But it really wreaked havoc with me.
