If you have GNC's in Canada, they carry both supplements. Wal-Mart carries the COQ10, and so does Rite Aid and many other pharmacies in the vitamin section. L-carnitine is a bit trickier to find. If you can't find it locally, it's available online at both E-bay and other vitamin sites. One very reasonably priced site for many supplements (including the 2 talked about here) is http://www.puritan.com . Good luck finding a place to buy them. I also saw someone ask if they worked, well I know they've helped me, but as with everything discussed here it may or may not help you. You'll never know unless you try. However, even if it doesn't help you in loosing weight they are both products which promote healthy heart function and aid in fat burning, so they can't hurt.
