My young horse has had a creaky fetlock joint that locks up sometimes. He’s had this since he was a yearling. I think it’s congenital or an old pasture injury. He’s been gettin Reach Joint Supplement for over three years now and the only time it “flares” up is if I run out of supplement and he has to go w/o it for more than a week. He gets 1 scoop in the morning-less than the reccomended dosage-works like a charm.I give a similar product to my dogs-not because they have joint issues- as a preventative. Flaxseed is a natural anti-inflamatory and may also help.
