These were some of the best glucosamine and chondroitin pills I found based on their price, effectiveness and their strength. You can find a less expensive source however you end up taking three to six pills a day! Definitely worth buying the extra strength. Thankfully I don't need these any more since I went gluten free, but I understand that is difficult for many people. Definitely be sure to also drink plenty of water with these pills as with any other concentrated and coated supplement. I do not have arthritis or any other form joint ailment, so I am no expert on how well they work for those, but my joint pain was non existent as long as I took them everyday. I did also notice that it helped with the pain from my cyst, that also being flared up from gluten consumption. It is still there now, however it does not give me any pain. After my mother had join issues with her foot and getting on a glucosamine regimen cleared that right up.
