I just ordered Smartvite Senior from Smartpak for my 20 yr old horse. Long story, but he is lacking in vitamins and minerals and has always had a somewhat "dull" appearance, and wounds take a ridiculously long time to heal. He is also a hard keeper. (teeth checked regularly, wormed regularly, fecals checked and negative) Kind of mad at myself as I never really analyzed how little he was getting in the vit/min department even on TC senior and joint supplement that does have vit/min in it. He is low in things like B vitamins, zinc and copper among many others including potassium and magnesium, and unfortunately doesn't eat alot of hay due to worn down back teeth. He does get alfalfa cubes and will eat a flake or two of alf/grass mix a night, so I put him on the "grass" formula of Smartvite which is meant for grass or grass/alf mix eaters.
His issues have been the slow wound healing, hair not growing back in those areas either at all or very sparsely. Dull coat, poor winter coat, and just dull at times - like "blah" would rather nap right now! No wonder he perks up when I give him a banana, LOL - he loves them and turns out they have the potassium he is lacking!
The opinions/testimonials on Smartpak's site for the Smartvite is pretty impressive.
For those of you who added a vit/min supplement to your horse's diet, what were your results? Were there noticeable improvements? Any Smartvite users?
