Potentially dangerous supplement
This firms up all connective tissue...including the tissue that lines your blood vessels. I am 42 yo woman who took this supplement for almost a year. Initially, I was pleased with the aesthetic firming that this supplement gave me. However; over time I started experiencing bursting blood vessels in my fingers.
I have since found out that collagen can firm up the connective tissue in blood vessels too. Collagen also has an inhibitory effect on platelets. Throwing clots with hardened blood vessels can cause spontaneous bursting of those blood vessels. I thank God that I did not have a thrombosis in my heart, head or lung!
We all have different reactions to various medications and supplements. It may be my individual chemistry that does not work with this supplement, but I think that consumers should be informed of these potentially dangerous side effects.
If you have smoke, have atherosclerosis or a predisposition to forming blood clots DO NOT TAKE THIS SUPPLEMENT!!!!
