IT bands are a bitch man, playing high school ball and a little bit at my hometown college did absolutely nothing good for mine. A quick exercise I did for strengthening was turning my feet inwards and doing very light leg presses. Also, try the IT band strectch, I am too lazy right at this moment but it helped me ALOT.
Also, for any type of connective tissue such as ligaments, and tendons Glucosamine is highly ineffective. Check out
Cissus RX by USP Labs in our board sponsor section, I, as well as many, many others reccomend this product highly.
