I took Boswelia Serrata (Frankinsense) for a while as well but didn't feel that it added much to what I was already doing. These supplements can be helpful but I spend a serious amount of money on this stuff, so when I try something new, I take it for a couple of months at least and then stop taking it for a week or so to determine if it's really helping. That's how I determined that the Glucosamine/Chondroitin I was taking was really helping, i.e. I stopped taking it for a while and could tell after a week how much of a difference it was making.
