I am 50 years old and have been struggling with rheumatism in my knees for more than 20 years. It was so bad that I got up early in the morning and could not climb stairs at all. When I first sat it was hard to get up. About 6 months ago I read the product on Facebook and decided to invest immediately in the hope that it would improve my mobility. I also play squash and because of the nature of the matter it also became so bad that I had to give up. After only one month, I felt a significant difference. I got up much easier in the morning and my knees did not hurt as much as in the past. I also climb many easier stairs and walk with much more convenience. Not only is the pain better, but my nails and hair grow so fast that I have to do it every three weeks, where I could last for 5/6 weeks. I also sleep more calmly and feel like I have more energy. This is truly a fantastic product and it tastes delicious. I would recommend it to anyone who has a pain or an ailment, because it's really a "miracle" treatment. To feel so much better at my age is truly fantastic.
