Briefly, I messed up both knees doing weird leg exercises in the park late this past summer, and it was so bad after about 2 weeks, I had trouble walking up the stairs, and had to hold on to the railing to go down. Imagine “Walter Brennan” from the old movies. That was me. I happened to hear Kevin Trudeau on his radio show talking about Royal Velvet, and he was interviewing the company spokesperson. I ordered it. I used it the first day, and when I woke up, my knee was tight, but there was no pain. By the second day, I had no pain. I was not only surprised, but stunned. I am a hard sell on health products. I have used Royal Velvet ever since. A friend who had some knee pain also tried it when I told her about my experience. Again, she also had a skeptical view. Within 2 days her knee felt better. I am sure there are other benefits. I have a lot more energy, and I actually sleep better. With my sleep, I have had terrible sleeping problems ever since I can remember. NOTHING helped. The fact I can now sleep 4 hours without waking up out of a sound sleep, for no reason, is amazing. Royal Velvet is a superb supplement that I will take from now on. This skeptic recommends the product highly!
