gold label glucosmine - my large lad has this in the winter to help ease the stiffness and works pretty well, he just gets one scoop to take the edge off.
I give my pony EPA from Holland and Barrett! At the minute its £4.99 for 250 capsules. High concentrated omega 3 fatty acids. 3 a day is still far cheaper than equine supplements!
i feed glucocime/condritin from natures best £18 for 3 months supply and cider vinegar from morissons 79p a bottle just got some vedge oil form morrisons today to see if that helps! Oh and a bute a day!!!!! (as per vets instructions before i get told off!!!)
I use Cortaflex on my horse with cronic arthritis in his neck - allied with nobute he is like a different horse. I decided to go down the expensive route due to his extreme health problem.
