In October I had a cartilage Transplantation of the left knee. From my orthopedic surgeon told me I had to leave after hyaluronic inject into the joint. Everyone who was operated on knee will ever agree with me that no one wants to voluntarily cut still inject the knee. So I searched for alternatives to these syringes whose efficacy has not really confirmed. In a journal I have become aware of glucosamine so I ordered this powder because one unlike capsules can dose the amount itself. Prescribed taking a teaspoon corresponds to 1000 mg glucosamine, I naturally raised. The recommended daily intake is 1250 mg glucosamine. So I take every day 1.5 teaspoons to me. Of course not pure, that makes no long :) But since glucosamine is water I mix it with water or juice. Then the taste is tolerable and after a while it even tastes After the operation I had a permanent crack in the knee got worse after I had my physiotherapy. After 2-3 week, reduced cracking, now after almost five weeks cracking is completely gone. The mobility has increased without the frightening cracking. I can only recommend to anyone this powder taking. It really works and is in contrast to the expensive Hyaluronspritzen (per unit approx 250 euros) more than just favorable lubricating effect for all joints and really effective. I will definitely order it again.
