Had my horse on it for a week and a half with no change yet. Will give it a few weeks and if no change will go back on the Equistro one which i know works but is more expensive!
Works well on every horse I've seen on it.
Has both magnesium and L-trytophan as the active ingredients and contains the most L-trytophan of any of the daily supplement calmers on the market.
There Super Kalm paste is a mega strong version of it great for shows but very strong so would only use if the normal version isn't strong enough. Also very expensive.
